问题:

I've got a repository which is integrated with travis. I've got QUnit tests which I'd like to run from grunt/node server side and AMD (requirejs). This is the source of my AMD init.js:

(function () {
    require.config({
        baseUrl: "../src"
    });

    require(["../test/suites/basic",
        '../test/qunit-extend',
        'qunit'
    ], function(BasicTests) {
        QUnit.config.autoload = false;
        QUnit.config.autostart = false;
        BasicTests.run();
        QUnit.load();
        QUnit.start();
    });
}());

When I run those QUnit tests within my browser - everything works perfectly. But when I try to run them from grunt level (server-side using phantomjs), it fails. I get:

Running "qunit:all" (qunit) task
Testing test/index.html 
Warning: PhantomJS timed out, possibly due to a missing QUnit start() call. Use --force to continue.

all the time. I was trying to do evetyrhing the same way as it's done in this tutorial, but still I get wrong results (phantom being hanged instead serving QUnit tests)...

回答1:

I am using grunt-contrib-qunit to run QUnit tests via grunt. It uses phantomjs internally.

I was getting the same error as the OP after upgrading grunt-contrib-qunit to the latest version (0.7.0):

PhantomJS timed out, possibly due to a missing QUnit start() call.

To fix this problem, I had to first load QUnit via require() and then execute QUnit.start() and define all my QUnit modules and tests after that.

The HTML file looks something like this:

<!DOCTYPE html>
<html>
<head>
    <title>QUnit + RequireJS + PhantomJS</title>
    <link rel="stylesheet" href="lib/qunit/qunit/qunit.css">
</head>
<body>
    <div id="qunit"></div>
    <div id="qunit-fixture"></div>
    <script src="lib/requirejs/require.js"></script>
    <script src="mytests.js"></script>
</body>
</html>

Then the mytests.js file:

require.config({
    paths: {
        'qunit': 'lib/qunit/qunit/qunit'
    }
});

require(['qunit'], function(QUnit) {

    QUnit.start();

    QUnit.module('My Module');

    QUnit.test('some normal test', function(assert) {

        assert.ok(true, 'can run a normal QUnit test');
    });

    QUnit.test('some asynchronous test', function(assert) {

        var done = assert.async();

        setTimeout(function() {

            assert.ok(true, 'can run an asynchronous QUnit test');
            done();

        }, 50);
    });
});
