qunit-harness

A library for running qunit tests on a local machine and in the SauceLabs environment.

Install

$ npm install qunit-harness

Usage

var QUnitHarness = require('qunit-harness');

function configQunitServerApp (app) {
    app.post('/my-custom-request', function (req, res) {
        res.end('ok');
    });
}

function before () {
    // do some stuff when the server is created
}

function after () {
    // do some stuff when the server is about to be closed
}

//Local machine testing
var qunitHarness = new QUnitHarness
    //specify the path to the tests
    .fixtures('/tests/')
    //specify qunit server ports
    .port(2000)             //by default 1335
    .crossDomainPort(2001)  //by default 1336
    //add the index.js script content as <script src='/tested-script.js'> to the head of the test page
    .scripts([{ src: '/tested-script.js', path: '/lib/index.js' }])
    .css([{ src: '/style.css', path: '/lib/style.css' }])
    //extend the qunit server application for test purposes
    .configApp(configQunitServerApp)
    .before(before)
    .after(after)
    .create();

QUnit tests

Wait for an async action

window.QUnitGlobals.wait(condition, ms);    // returns Promise
// condition is a function
// The test will fail with the timeout error if 'condition' returns 'false' within 'ms' milliseconds (3000 ms by default).

Example:

asyncTest('test with wait', function () {
    var resolved = false;

    window.setTimeout(function () {
        resolved = true;
    }, 50);

    window.QUnitGlobals.wait(function () {
            return resolved;
        })
        .then(function () {
            ok(true);
            start();
        });
});

Wait for an iframe action

window.QUnitGlobals.waitForIframe(iframe, timeout);    // returns Promise
// iframe is an iframe element to wait for
// The test will fail with the timeout error if the 'load' event for the iframe is not raised within <timeout> or
// window.QUnitGlobals.WAIT_FOR_IFRAME_TIMEOUT ms.

Example:

window.QUnitGlobals.WAIT_FOR_IFRAME_TIMEOUT = 5000;

asyncTest('test with wait for iframe', function () {
    var iframe = document.createElement('iframe');

    iframe.src = window.QUnitGlobals.getResourceUrl('../data/iframe.html');

    document.body.appendChild(iframe);

    window.QUnitGlobals.waitForIframe(iframe).then(function () {
        ok(true);
        start();
    });
});

Get test server hostname

window.QUnitGlobals.hostname;               //http://localhost:1335/
window.QUnitGlobals.crossDomainHostname;   //http://localhost:1336/

Get test resource

window.QUnitGlobals.getResourceUrl(pathToResourceFile[, urlAlias])

By default the resource has the http://<hostname>/test-resource?filePath=<resourceFilePath>&base=<currentTestFilePath> url. To customize the url, use the urlAlias argument:

window.QUnitGlobals.getResourceUrl('../data/script.js', 'my-custom-script/script.js');
//returns "http://<hostname>/test-resource/my-custom-script/script.js?filePath=..."

Example:

<!-- data/iframe.html -->
<!DOCTYPE html>
<html>
<head>
    <title>Iframe page</title>
    <meta charset="utf-8">
</head>
<body>
    Some content
</body>
</html>

// tests/test1-test.js
asyncTest('iframe test', function () {
    var iframeSrc = window.QUnitGlobals.getResourceUrl('../data/iframe.html', 'iframe.html');
    $('<iframe></iframe>').src(iframeSrc).appendTo('body');
    //appends an iframe with the url http://<hostname>/test-resource/iframe.html
    ...
});

Run a test with some markup on the page

Put the testname-test.js and testname.html files to the folder with the -test postfix. Then, the markup from the .html file will be included into the testname-test.js test page.

Example:

<!-- tests/markup-test/index.html -->
<div id="#test-element"></div>

// tests/markup-test/index-test.js
test('check element', function () {
    ok($('#test-element').length);  //success
});
