A test framework agnostic vcr implementation that uses nock.
npm install nock-vcr-recorderA test framework agnostic vcr implementation that uses
nock. Can be used in isolation or test specific
libraries can be written around it.
``bash`
npm install --save-dev nock-vcr-recorder
Use vcr.useCassette and pass in a callback with the test to run. All http
requests will be recorded using nock and stored in a cassettes directory for
playback on later test runs. It expects the callback to return a promise for
asyncronous actions and it returns a promise that resolves when it's finished.
Example using mocha:
`js
var RSVP = require('rsvp');
var request = RSVP.denodeify(require('request'));
var assert = require('assert');
var vcr = require('nock-vcr-recorder');
describe('standard test', function() {
it('caches request', function() {
return vcr.useCassette('normal test - works', function() {
return request('http://localhost:4000/users').then(function() {
assert(true, 'request works');
});
});
});
});
// Usage with test specific options
//
// This test will not record the request to localhost:4000 and it will not use
// any saved fixtures
describe('normal test', function() {
it('works', function(done) {
return vcr.useCassette('normal test - works', {
excludeScope: 'localhost:4000'
mode: 'all'
}, function() {
return request('http://localhost:4000/users').then(function() {
assert(true, 'request works');
});
});
});
});
`
You can also call vcr.nockReset() if you need to programmatically remove all mocks.
Defaults:
`js
{
// Don't record any requests to this scope
// It can be an array or string
excludeScope: ['localhost', '127.0.0.1', '0.0.0.0'],
// Re-record and overwrite your current fixtures
// Possible values: 'all'
mode: undefined,
// Write recorded fixtures when the test fails. We don't do this by default
writeOnFailure: false
}
`
To overide these you can call vcr.config with an object to
override them for ALL tests.
You also are able to pass in test specific options as the second parameter to
vcr.useCassette()`. See the "Usage" section above for an example.
