` javascript
var soap = require('soap');
var url = 'http://example.com/wsdl?wsdl';
var args = {name: 'value'};
soap.createClient(url, function(err, client) {
client.MyFunction(args, function(err, result) {
console.log(result);
});

`
This client has a built in WSDL cache. You can use the disableCache option to disable it.
$3
` javascript
var soap = require('soap');
var url = 'http://example.com/wsdl?wsdl';
var args = {name: 'value'};
soap.createClientAsync(url).then((client) => {
return client.MyFunctionAsync(args);
}).then((result) => {
console.log(result);
});
`
This client has a built in WSDL cache. You can use the disableCache option to disable it.
#### Options
The options argument allows you to customize the client with the following properties:
- endpoint: to override the SOAP service's host specified in the .wsdl file.
- envelopeKey: to set specific key instead of <soap:Body>soap:Body>
.
- preserveWhitespace: to preserve leading and trailing whitespace characters in text and cdata.
- escapeXML: escape special XML characters in SOAP message (e.g. &, >, < etc), default: true.
- suppressStack: suppress the full stack trace for error messages.
- returnFault: return an Invalid XML SOAP fault on a bad request, default: false.
- forceSoap12Headers: to set proper headers for SOAP v1.2.
- httpClient: to provide your own http client that implements request(rurl, data, callback, exheaders, exoptions).
- request: to override the request module.
- wsdl_headers: custom HTTP headers to be sent on WSDL requests.
- wsdl_options: custom options for the request module on WSDL requests.
- disableCache: don't cache WSDL files, request them every time.
- overridePromiseSuffix: if your wsdl operations contains names with Async suffix, you will need to override the default promise suffix to a custom one, default: Async.
- normalizeNames: if your wsdl operations contains names with non identifier characters ([^a-z$_0-9]), replace them with _. Note: if using this option, clients using wsdls with two operations like soap:method and soap-method will be overwritten. Then, use bracket notation instead (client['soap:method']()).
- namespaceArrayElements: provides support for nonstandard array semantics. If true, JSON arrays of the form {list: [{elem: 1}, {elem: 2}]} are marshalled into xml as . If false, marshalls into . Default: true.
Note: for versions of node >0.10.X, you may need to specify {connection: 'keep-alive'} in SOAP headers to avoid truncation of longer chunked responses.
$3
server can be a http Server or express framework based server
wsdl is an xml string that defines the service.
` javascript
var myService = {
MyService: {
MyPort: {
MyFunction: function(args) {
return {
name: args.name
};
},
// This is how to define an asynchronous function.
MyAsyncFunction: function(args, callback) {
// do some work
callback({
name: args.name
});
},
// This is how to receive incoming headers
HeadersAwareFunction: function(args, cb, headers) {
return {
name: headers.Token
};
},
// You can also inspect the original req
reallyDetailedFunction: function(args, cb, headers, req) {
console.log('SOAP reallyDetailedFunction request from ' + req.connection.remoteAddress);
return {
name: headers.Token
};
}
}
}
};
var xml = require('fs').readFileSync('myservice.wsdl', 'utf8');
//http server example
var server = http.createServer(function(request,response) {
response.end('404: Not Found: ' + request.url);
});
server.listen(8000);
soap.listen(server, '/wsdl', myService, xml);
//express server example
var app = express();
//body parser middleware are supported (optional)
app.use(bodyParser.raw({type: function(){return true;}, limit: '5mb'}));
app.listen(8001, function(){
//Note: /wsdl route will be handled by soap module
//and all other routes & middleware will continue to work
soap.listen(app, '/wsdl', myService, xml);
});
`
$3
You can pass in server and WSDL Options
using an options hash.
Server options include the below:
- pfx: A string or Buffer containing the private key, certificate and CA certs of the server in PFX or PKCS12 format. (Mutually exclusive with the key, cert and ca options.)
- key: A string or Buffer containing the private key of the server in PEM format. (Could be an array of keys). (Required)
- passphrase: A string of passphrase for the private key or pfx.
- cert: A string or Buffer containing the certificate key of the server in PEM format. (Could be an array of certs). (Required)
- ca: An array of strings or Buffers of trusted certificates in PEM format. If this is omitted several well known "root" CAs will be used, like VeriSign. These are used to authorize connections.
- crl : Either a string or list of strings of PEM encoded CRLs (Certificate Revocation List)
- ciphers: A string describing the ciphers to use or exclude, separated by :. The default cipher suite is:
` javascript
var xml = require('fs').readFileSync('myservice.wsdl', 'utf8');
soap.listen(server, {
// Server options.
path: '/wsdl',
services: myService,
xml: xml,
// WSDL options.
attributesKey: 'theAttrs',
valueKey: 'theVal',
xmlKey: 'theXml'
});
`
$3
If the log method is defined it will be called with 'received' and 'replied'
along with data.
` javascript
server = soap.listen(...)
server.log = function(type, data) {
// type is 'received' or 'replied'
};
`
$3
Server instances emit the following events:
* request - Emitted for every received messages.
The signature of the callback is function(request, methodName).
* headers - Emitted when the SOAP Headers are not empty.
The signature of the callback is function(headers, methodName).
The sequence order of the calls is request, headers and then the dedicated
service method.
$3
The so called one-way (or asynchronous) calls occur when an operation is called with no output defined in WSDL.
The server sends a response (defaults to status code 200 with no body) to the client disregarding the result of the operation.
You can configure the response to match the appropriate client expectation to the SOAP standard implementation.
Pass in oneWay object in server options. Use the following keys:
emptyBody: if true, returns an empty body, otherwise no content at all (default is false)
responseCode: default statusCode is 200, override it with this options (for example 202 for SAP standard compliant response)
$3
A service method can reply with a SOAP Fault to a client by throwing an
object with a Fault property.
` javascript
throw {
Fault: {
Code: {
Value: 'soap:Sender',
Subcode: { value: 'rpc:BadArguments' }
},
Reason: { Text: 'Processing Error' }
}
};
`
To change the HTTP statusCode of the response include it on the fault. The statusCode property will not be put on the xml message.
` javascript
throw {
Fault: {
Code: {
Value: 'soap:Sender',
Subcode: { value: 'rpc:BadArguments' }
},
Reason: { Text: 'Processing Error' },
statusCode: 500
}
};
`
$3
If server.authenticate is not defined then no authentication will take place.
` javascript
server = soap.listen(...)
server.authenticate = function(security) {
var created, nonce, password, user, token;
token = security.UsernameToken, user = token.Username,
password = token.Password, nonce = token.Nonce, created = token.Created;
return user === 'user' && password === soap.passwordDigest(nonce, created, 'password');
};
`
$3
The server.authorizeConnection method is called prior to the soap service method.
If the method is defined and returns false then the incoming connection is
terminated.
` javascript
server = soap.listen(...)
server.authorizeConnection = function(req) {
return true; // or false
};
`
SOAP Headers
$3
A service method can look at the SOAP headers by providing a 3rd arguments.
` javascript
{
HeadersAwareFunction: function(args, cb, headers) {
return {
name: headers.Token
};
}
}
`
It is also possible to subscribe to the 'headers' event.
The event is triggered before the service method is called, and only when the
SOAP Headers are not empty.
` javascript
server = soap.listen(...)
server.on('headers', function(headers, methodName) {
// It is possible to change the value of the headers
// before they are handed to the service method.
// It is also possible to throw a SOAP Fault
});
`
First parameter is the Headers object;
second parameter is the name of the SOAP method that will called
(in case you need to handle the headers differently based on the method).
$3
Both client & server can define SOAP headers that will be added to what they send.
They provide the following methods to manage the headers.
#### addSoapHeader(soapHeader[, name, namespace, xmlns]) - add soapHeader to soap:Header node
##### Parameters
- soapHeader Object({rootName: {name: 'value'}}), strict xml-string,
or function (server only)
For servers only, soapHeader can be a function, which allows headers to be
dynamically generated from information in the request. This function will be
called with the following arguments for each received request:
- methodName The name of the request method
- args The arguments of the request
- headers The headers in the request
- req The original request object
The return value of the function must be an Object({rootName: {name: 'value'}})
or strict xml-string, which will be inserted as an outgoing header of the
response to that request.
For example:
` javascript
server = soap.listen(...);
server.addSoapHeader(function(methodName, args, headers, req) {
console.log('Adding headers for method', methodName);
return {
MyHeader1: args.SomeValueFromArgs,
MyHeader2: headers.SomeRequestHeader
};
// or you can return "SomeValue "
});
`
##### Returns
The index where the header is inserted.
##### Optional parameters when first arg is object :
- name Unknown parameter (it could just a empty string)
- namespace prefix of xml namespace
- xmlns URI
#### changeSoapHeader(index, soapHeader[, name, namespace, xmlns]) - change an already existing soapHeader
##### Parameters
- index index of the header to replace with provided new value
- soapHeader Object({rootName: {name: 'value'}}), strict xml-string
or function (server only)
See addSoapHeader for how to pass a function into soapHeader.
#### getSoapHeaders() - return all defined headers
#### clearSoapHeaders() - remove all defined headers
Client
An instance of Client is passed to the soap.createClient callback. It is used to execute methods on the soap service.
$3
` javascript
client.describe() // returns
{
MyService: {
MyPort: {
MyFunction: {
input: {
name: 'string'
}
}
}
}
}
`
$3
$3
` javascript
client.MyFunction({name: 'value'}, function(err, result, rawResponse, soapHeader, rawRequest) {
// result is a javascript object
// rawResponse is the raw xml response string
// soapHeader is the response soap header as a javascript object
// rawRequest is the raw xml request string
})
`
The args argument allows you to supply arguments that generate an XML document inside of the SOAP Body section.
The options object is optional and is passed to the request-module.
Interesting properties might be:
* timeout: Timeout in milliseconds
* forever: Enables keep-alive connections and pools them
$3
` javascript
client.MyFunctionAsync({name: 'value'}).then((result) => {
// result is a javascript array containing result, raw and soapheader
// result is a javascript object
// raw is the raw response
// soapHeader is the response soap header as a javascript object
})
`
The args argument allows you to supply arguments that generate an XML document inside of the SOAP Body section.
##### Example with JSON for the args
The example above uses {name: 'value'} as the args. This may generate a SOAP messages such as:
` javascript
value
`
Note that the "Request" element in the output above comes from the WSDL. If an element in args contains no namespace prefix, the default namespace is assumed. Otherwise, you must add the namespace prefixes to the element names as necessary (e.g., ns1:name).
Currently, when supplying JSON args, elements may not contain both child elements and a text value, even though that is allowed in the XML specification.
##### Example with XML String for the args
You may pass in a fully-formed XML string instead the individual elements in JSON args and attributes that make up the XML. The XML string should not contain an XML declaration (e.g., ) or a document type declaration (e.g., ).
`
var args = { _xml: "
elementvalue
"
};
`
You must specify all of the namespaces and namespace prefixes yourself. The element(s) from the WSDL are not utilized as they were in the "Example with JSON as the args" example above, which automatically populated the "Request" element.
$3
` javascript
client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
// result is a javascript object
})
`
#### Options (optional)
- Accepts any option that the request module accepts, see here.
- For example, you could set a timeout of 5 seconds on the request like this:
` javascript
client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
// result is a javascript object
}, {timeout: 5000})
`
- You can measure the elapsed time on the request by passing the time option:
` javascript
client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
// client.lastElapsedTime - the elapsed time of the last request in milliseconds
}, {time: true})
`
- Also, you could pass your soap request through a debugging proxy such as Fiddler or Betwixt.
` javascript
client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
// client.lastElapsedTime - the elapsed time of the last request in milliseconds
}, {proxy: 'http://localhost:8888'})
`
- You can modify xml (string) before call:
` javascript
client.MyService.MyPort.MyFunction({name: 'value'}, function(err, result) {
// client.lastElapsedTime - the elapsed time of the last request in milliseconds
}, {postProcess: function(_xml) {
return _xml.replace('text', 'newtext');
}})
`
#### Extra Headers (optional)
Object properties define extra HTTP headers to be sent on the request.
- Add custom User-Agent:
`javascript
client.addHttpHeader('User-Agent', CustomUserAgent);
`
#### Alternative method call using callback-last pattern
To align method call signature with node' standard callback-last patter and event allow promisification of method calls, the following method signatures are also supported:
`javascript
client.MyService.MyPort.MyFunction({name: 'value'}, options, function (err, result) {
// result is a javascript object
})
client.MyService.MyPort.MyFunction({name: 'value'}, options, extraHeaders, function (err, result) {
// result is a javascript object
})
`
$3
node-soap is still working out some kinks regarding namespaces. If you find that an element is given the wrong namespace prefix in the request body, you can add the prefix to it's name in the containing object. I.E.:
`javascript
client.MyService.MyPort.MyFunction({'ns1:name': 'value'}, function(err, result) {
// request body sent with
- Remove namespace prefix of param
`javascript
client.MyService.MyPort.MyFunction({':name': 'value'}, function(err, result) {
// request body sent with

Client instances emit the following events:
$3
Emitted before a request is sent. The event handler has the signature (xml, eid).
- _xml_ - The entire Soap request (Envelope) including headers.
- _eid_ - The exchange id.
$3
Emitted before a request is sent, but only the body is passed to the event handler. Useful if you don't want to log /store Soap headers. The event handler has the signature (message, eid).
- _message_ - Soap body contents.
- _eid_ - The exchange id.
$3
Emitted when an erroneous response is received. Useful if you want to globally log errors. The event handler has the signature (error, eid).
- _error_ - An error object which also contains the resoponse.
- _eid_ - The exchange id.
$3
Emitted after a response is received. This is emitted for all responses (both success and errors). The event handler has the signature (body, response, eid)
- _body_ - The SOAP response body.
- _response_ - The entire IncomingMessage response object.
- _eid_ - The exchange id.
An 'exchange' is a request/response couple.
Event handlers receive the exchange id in all events.
The exchange id is the same for the requests events and the responses events, this way you can use it to retrieve the matching request
when an response event is received.
By default exchange ids are generated by using node-uuid but you can use options in client calls to pass your own exchange id.
Example :
`javascript
client.MyService.MyPort.MyFunction(args , function(err, result) {
}, {exchangeId: myExchangeId})
`
Security
node-soap has several default security protocols. You can easily add your own
as well. The interface is quite simple. Each protocol defines these optional methods:
* addOptions(options) - a method that accepts an options arg that is eventually passed directly to request.
* addHeaders(headers) - a method that accepts an argument with HTTP headers, to add new ones.
* toXML() - a method that returns a string of XML to be appended to the SOAP headers. Not executed if postProcess is also defined.
* postProcess(xml, envelopeKey) - a method that receives the the assembled request XML plus envelope key, and returns a processed string of XML. Executed before options.postProcess.
$3
` javascript
client.setSecurity(new soap.BasicAuthSecurity('username', 'password'));
`
$3
` javascript
client.setSecurity(new soap.BearerSecurity('token'));
`
$3
_Note_: If you run into issues using this protocol, consider passing these options
as default request options to the constructor:
* rejectUnauthorized: false
* strictSSL: false
* secureOptions: constants.SSL_OP_NO_TLSv1_2 (this is likely needed for node >= 10.0)
If you want to reuse tls sessions, you can use the option forever: true.
` javascript
client.setSecurity(new soap.ClientSSLSecurity(
'/path/to/key',
'path/to/cert',
'/path/to/ca-cert', /*or an array of buffer: [fs.readFileSync('/path/to/ca-cert/1', 'utf8'),
'fs.readFileSync('/path/to/ca-cert/2', 'utf8')], */
{ /default request options like /
// strictSSL: true,
// rejectUnauthorized: false,
// hostname: 'some-hostname'
// secureOptions: constants.SSL_OP_NO_TLSv1_2,
// forever: true,
},
));
`
$3
_Note_: If you run into issues using this protocol, consider passing these options
as default request options to the constructor:
* rejectUnauthorized: false
* strictSSL: false
* secureOptions: constants.SSL_OP_NO_TLSv1_2 (this is likely needed for node >= 10.0)
If you want to reuse tls sessions, you can use the option forever: true.
` javascript
client.setSecurity(new soap.ClientSSLSecurityPFX(
'/path/to/pfx/cert', // or a buffer: [fs.readFileSync('/path/to/pfx/cert', 'utf8'),
'path/to/optional/passphrase',
{ /default request options like /
// strictSSL: true,
// rejectUnauthorized: false,
// hostname: 'some-hostname'
// secureOptions: constants.SSL_OP_NO_TLSv1_2,
// forever: true,
},
));
`
$3
WSSecurity implements WS-Security. UsernameToken and PasswordText/PasswordDigest is supported.
` javascript
var options = {
hasNonce: true,
actor: 'actor'
};
var wsSecurity = new soap.WSSecurity('username', 'password', options)
client.setSecurity(wsSecurity);
`
the options object is optional and can contain the following properties:
* passwordType: 'PasswordDigest' or 'PasswordText' (default: 'PasswordText')
* hasTimeStamp: adds Timestamp element (default: true)
* hasTokenCreated: adds Created element (default: true)
* hasNonce: adds Nonce element (default: false)
* mustUnderstand: adds mustUnderstand=1 attribute to security tag (default: false)
* actor: if set, adds Actor attribute with given value to security tag (default: '')
$3
WS-Security X509 Certificate support.
` javascript
var privateKey = fs.readFileSync(privateKeyPath);
var publicKey = fs.readFileSync(publicKeyPath);
var password = ''; // optional password
var wsSecurity = new soap.WSSecurityCert(privateKey, publicKey, password);
client.setSecurity(wsSecurity);
`
Handling XML Attributes, Value and XML (wsdlOptions).
Sometimes it is necessary to override the default behaviour of node-soap in order to deal with the special requirements
of your code base or a third library you use. Therefore you can use the wsdlOptions Object, which is passed in the
#createClient() method and could have any (or all) of the following contents:
`javascript
var wsdlOptions = {
attributesKey: 'theAttrs',
valueKey: 'theVal',
xmlKey: 'theXml'
}
`
If nothing (or an empty Object {}) is passed to the #createClient() method, the node-soap defaults (attributesKey: 'attributes', valueKey: '$value' and xmlKey: '$xml') are used.
$3
By default, node-soap uses $value as the key for any parsed XML value which may interfere with your other code as it
could be some reserved word, or the $ in general cannot be used for a key to start with.
You can define your own valueKey by passing it in the wsdl_options to the createClient call:
`javascript
var wsdlOptions = {
valueKey: 'theVal'
};
soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
// your code
});
`
$3
By default, node-soap uses $xml as the key to pass through an XML string as is; without parsing or namespacing it. It overrides all the other content that the node might have otherwise had.
For example :
`javascript
{
dom: {
nodeone: {
$xml: '
siblingnode: 'Cant see me.'
},
nodetwo: {
parentnode: {
attributes: {
type: 'type'
},
childnode: ''
}
}
}
};
`
could become
`xml
`
You can define your own xmlKey by passing it in the wsdl_options object to the createClient call:
`javascript
var wsdlOptions = {
xmlKey: 'theXml'
};
soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
// your code
});
`
$3
By default, node-soap uses attributes as the key to define a nodes attributes.
` javascript
{
parentnode: {
childnode: {
attributes: {
name: 'childsname'
},
$value: 'Value'
}
}
}
`
could become
` xml
Value
`
However, attributes may be a reserved key for some systems that actually want a node called attributes
`xml
`
You can define your own attributesKey by passing it in the wsdl_options object to the createClient call:
`javascript
var wsdlOptions = {
attributesKey: '$attributes'
};
soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
client.method({
parentnode: {
childnode: {
$attributes: {
name: 'childsname'
},
$value: 'Value'
}
}
});
});
`
$3
In rare cases, you may want to precisely control the namespace definition that is included in the root element.
You can specify the namespace definitions by setting the overrideRootElement key in the wsdlOptions like so:
`javascript
var wsdlOptions = {
overrideRootElement: {
namespace: 'xmlns:tns',
xmlnsAttributes: [{
name: 'xmlns:ns2',
value: "http://tempuri.org/"
}, {
name: 'xmlns:ns3',
value: "http://sillypets.com/xsd"
}]
}
};
`
To see it in practice, have a look at the sample files in: test/request-response-samples/addPets__force_namespaces
$3
Sometimes it's useful to handle deserialization in your code instead of letting node-soap do it.
For example if the soap response contains dates that are not in a format recognized by javascript, you might want to use your own function to handle them.
To do so, you can pass a customDeserializer object in options. The properties of this object are the types that your deserializer handles itself.
Example :
`javascript
var wsdlOptions = {
customDeserializer: {
// this function will be used to any date found in soap responses
date: function (text, context) {
/* text is the value of the xml element.
context contains the name of the xml element and other infos :
{
name: 'lastUpdatedDate',
object: {},
schema: 'xsd:date',
id: undefined,
nil: false
}
*/
return text;
}
}
};
soap.createClient(__dirname + '/wsdl/default_namespace.wsdl', wsdlOptions, function (err, client) {
...
});
`
$3
The XML specification specifies that there is no semantic difference between and , and node-soap defaults to using the format. But if your web service is particular, or if there is a stylistic preference, the useEmptyTag option causes tags with no contents to use the format instead.
`javascript
var wsdlOptions = {
useEmptyTag: true
};
`
For example: { MyTag: { attributes: { MyAttr: 'value' } } } is:
* Without useEmptyTag:
* With useEmptyTag set to true:
Handling "ignored" namespaces
If an Element in a schema definition depends on an Element which is present in the same namespace, normally the tns:
namespace prefix is used to identify this Element. This is not much of a problem as long as you have just one schema defined
(inline or in a separate file). If there are more schema files, the tns: in the generated soap file resolved mostly to the parent wsdl file,
which was obviously wrong.
node-soap now handles namespace prefixes which shouldn't be resolved (because it's not necessary) as so called ignoredNamespaces
which default to an Array of 3 Strings (['tns', 'targetNamespace', 'typedNamespace']).
If this is not sufficient for your purpose you can easily add more namespace prefixes to this Array, or override it in its entirety
by passing an ignoredNamespaces object within the options you pass in soap.createClient() method.
A simple ignoredNamespaces object, which only adds certain namespaces could look like this:
`
var options = {
ignoredNamespaces: {
namespaces: ['namespaceToIgnore', 'someOtherNamespace']
}
}
`
This would extend the ignoredNamespaces of the WSDL processor to ['tns', 'targetNamespace', 'typedNamespace', 'namespaceToIgnore', 'someOtherNamespace'].
If you want to override the default ignored namespaces you would simply pass the following ignoredNamespaces object within the options:
`
var options = {
ignoredNamespaces: {
namespaces: ['namespaceToIgnore', 'someOtherNamespace'],
override: true
}
}
`
This would override the default ignoredNamespaces of the WSDL processor to ['namespaceToIgnore', 'someOtherNamespace']. (This shouldn't be necessary, anyways).
If you want to override the default ignored namespaces you would simply pass the following ignoredNamespaces object within the options:
`
var options = {
ignoredNamespaces: {
namespaces: ['namespaceToIgnore', 'someOtherNamespace'],
override: true
}
}
`
This would override the default ignoredNamespaces of the WSDL processor to ['namespaceToIgnore', 'someOtherNamespace']. (This shouldn't be necessary, anyways).
Handling "ignoreBaseNameSpaces" attribute
If an Element in a schema definition depends has a basenamespace defined but the request does not need that value, for example you have a "sentJob" with basenamespace "v20"
but the request need only: set in the tree structure, you need to set the ignoreBaseNameSpaces to true. This is set because in a lot of workaround the wsdl structure is not correctly
set or the webservice bring errors.
By default the attribute is set to true.
An example to use:
A simple ignoredNamespaces object, which only adds certain namespaces could look like this:
`
var options = {
ignoredNamespaces: true
}
`
soap-stub
Unit testing services that use soap clients can be very cumbersome. In order to get
around this you can use soap-stub in conjunction with sinon to stub soap with
your clients.
$3
`javascript
// test-initialization-script.js
var sinon = require('sinon');
var soapStub = require('soap/soap-stub');
var urlMyApplicationWillUseWithCreateClient = 'http://path-to-my-wsdl';
var clientStub = {
SomeOperation: sinon.stub()
};
clientStub.SomeOperation.respondWithError = soapStub.createErroringStub({..error json...});
clientStub.SomeOperation.respondWithSuccess = soapStub.createRespondingStub({..success json...});
soapStub.registerClient('my client alias', urlMyApplicationWillUseWithCreateClient, clientStub);
// test.js
var soapStub = require('soap/soap-stub');
describe('myService', function() {
var clientStub;
var myService;
beforeEach(function() {
clientStub = soapStub.getStub('my client alias');
soapStub.reset();
myService.init(clientStub);
});
describe('failures', function() {
beforeEach(function() {
