`Module`

Methods and options (including the one letter shorthands) are the same when using as a Node module, however a more verbose version of both commands (methods) and options (parameters) are available and encouraged to use for code clarity.

`$3`

- getTestStatus(id, options, callback)-getTestResults(id, options, callback)-getLocations(options, callback)-getTesters(options, callback)-getTestBalance(options, callback)-runTest(url_or_script, options, callback)-runTestAndWait(url_or_script, options, callback)-restartTest(id, options, callback)-cancelTest(id, options, callback)-getHARData(id, options, callback)-getPageSpeedData(id, options, callback)-getUtilizationData(id, options, callback)-getRequestData(id, options, callback)-getTimelineData(id, options, callback)-getNetLogData(id, options, callback)-getChromeTraceData(id, options, callback)-getConsoleLogData(id, options, callback)-getTestInfo(id, options, callback)-getHistory(days, options, callback)-getGoogleCsiData(id, options, callback)-getResponseBody(id, options, callback)-getWaterfallImage(id, options, callback)-getScreenshotImage(id, options, callback)-createVideo(tests, options, callback)-getEmbedVideoPlayer(id, options, callback)-listen(port, options, callback)-scriptToString(script)

#### Notes

- getWaterfallImage and getScreenshotImage callback function has a third parameter info which is an object with {type: 'image/jpeg or png', encoding: 'utf8 or binary'}-scriptToString script array values 1-N are optional. e.g:

`javascript const script = wpt.scriptToString([ { logData: 0 }, { navigate: "http://foo.com/login" }, { logData: 1 }, { setValue: ["name=username", "johndoe"] }, { setValue: ["name=password", "12345"] }, { submitForm: "action=http://foo.com/main" }, "waitForComplete", ]);

`javascript wpt.getTestResults("121025_PT_N8K", (err, data) => { console.log(err || data); });`

#### 6. Get test waterfall thumbnail from repeat view as data URI

`javascript wpt.getWaterfallImage( "121025_PT_N8K", { thumbnail: true, repeatView: true, dataURI: true, }, (err, data, info) => { console.log(err || data, info); } );`

#### Run test on https://docs.webpagetest.org/api/integrations/ and poll results every 5 seconds timing out in 60 seconds

`javascript wpt.runTest( "https://docs.webpagetest.org/api/integrations/", { pollResults: 5, timeout: 60 }, (err, data) => { console.log(err || data); } );`

#### Or run test on https://docs.webpagetest.org/api/integrations/ and wait results listening on localhost\ port 8000\\*

`javascript wpt.runTest( "https://docs.webpagetest.org/api/integrations/", { waitResults: "localhost:8000" }, (err, data) => { console.log(err || data); } );`

_\* hostname and port are optional, defaults to \:\<8000\>_

_\\ localhost:8000 must be reacheable from WebPageTest server_

`Server mode`

WebPageTest API Wrapper comes with a handy RESTful API proxy

`$3`

`bash webpagetest listen 8080 --server wpt.foo.com`

`bash server listening on port 8080 http://localhost:8080`

`bash curl http://localhost:8080/help curl http://localhost:8080/test/webpagetest.org/?location=SanJose_IE9`

`bash webpagetest listen 8443 --key key.pem --cert cert.pem --server wpt.foo.com`

`bash server listening on port 8443 https://localhost:8443`

#### Notes

- port _8080_ is optional, default port is _7791_ -wpt.foo.com is overriding the default www.webpagetest.org server but can still be overridden with serveroption - when _--key_ and _--cert_ are provided, HTTPS is used instead of default HTTP server

`$3`

`javascript const server = wpt.listen(8080, (err, data) => { if (err) throw err; console.log("listening on " + data.url); }); // listen on port 8080 (optional), default port is 7791

setTimeout(() => { server.close(() => { console.log("server closed"); }); }, 10000); // wait for 10s before stop listening`

`Batch`

Batch command is available as command line only and loads a batch file containing one WebPageTest CLI command with options per line. It runs all commands in parallel, but returns an array of results in order as they appear in the batch file once all results are ready. The exit status code is the sum of all individual commands' exit status code.

By running

`bash webpagetest batch commands.txt`

where commands.txt contains:

`bash test https://docs.webpagetest.org/api/integrations/ --first --location foo test https://docs.webpagetest.org/api/integrations/ --first --location bar`

It schedules the 2 tests above returning an array of size 2 in the same order as in commands.txt file:

`javascript [ { "statusCode": 200, "statusText": "Ok", "data": { "testId": "130715_AB_C1D", ... } }, { "statusCode": 200, "statusText": "Ok", "data": { "testId": "130715_CD_E2F", ... } } ]`

With exit status 0 in case none of commands returns an error:

`bash echo $? 0`

By running multiple sync tests, i.e. with either --poll or --wait, all tests are scheduled and results are polled or wait in parallel; meaning, if tests are set to run in different locations or same location with multiple agents, the final result might come together, but the result array will only return once _all_ tests are done. e.g.:

commands.txt:

`bash test https://docs.webpagetest.org/api/integrations/ --first --location foo --poll --timeout 60 test https://docs.webpagetest.org/api/integrations/ --first --location bar --poll --timeout 60`

`Test Specs (Continuous Integration)`

WebPageTest API Wrapper provides a simple seamless way to integrate WebPageTest with Continuous Integration tools.

See dedicated page

`Tests`

`bash npm test``
