I get the following when running the qunit-runner.js script with phantomjs:

TypeError: 'undefined' is not an object

qunit-runner.js:180

Any ideas?

QUnit.log isn't checking "details" is an object. console.log(details) within that function and add a check to verify it's an object at the top of that function.

gcoop commented Apr 25, 2012

have updated to include the test, you shouldn't get the above error now. For the record I am not actually using this script anymore, I migrated everything to user busterjs which does all this in a simpler fashion http://busterjs.org/

Should it not be:

if (!details.result || typeof details == "undefined") {

Added the "!"

After adding the "!" it's not throwing that error anymore, but it's alos not creating the xml output file.

It's also producing this error now (for every QUnit test): ReferenceError: Can't find variable: log

Plse ignore the "Can't find variable: log" error.

But, it's showing FAILED for even tests that passed, and is still not creating the output file.

Any ideas?

gcoop commented Apr 25, 2012

You might be using a different version of QUnit try this one https://gist.github.com/2488794

Brilliant! Thanks!

The console is now producing the correct results, but the XML output file only contains this:

gcoop commented Apr 25, 2012

Have updated the gist, I just checked we still have some tests being run with this on our ci server. Using that version of QUnit and the updated runner file you should be good to go.

I have updated both QUnit.js and the runner with ur latest versions, but still get the same output in the XML file.

Owner

gcoop commented Apr 25, 2012

try now. I have just run it manually and get xml file correctly with pass and failed tests defined.

Owner

gcoop commented Apr 25, 2012

sorry by try now, i mean update your file with the file i just updated above and run it.

Nope. Same result:

Owner

gcoop commented Apr 25, 2012

it wont overwrite the .xml file so make sure u delete it each time.

Yeah, I've tried that, but same results.

Owner

gcoop commented Apr 25, 2012

can you paste all the output of the command somewhere please (including the command line)

The command that I execute from the command line:
/usr/local/phantomjs/bin/phantomjs qunit-runner.js --qunit /Users/cas/Desktop/POC/baseline/test/qunit/qunit.js --tests /Users/cas/Desktop/POC/baseline/test --junit /Users/cas/Desktop/POC/baseline/test/qunit-results.xml

Command line output:

Not too sure then. The only extra info I can give you is all my test files follow the format below.

test("Some description about the test", function () {
ok(true === true, "true is equal to true");
});

XLM Output:

<?xml version="1.0" encoding="UTF-8"?> <testsuites name="testsuites"> </testsuites>

I have created a new test file and included your sample test, but get exactly the same results.

I've added this line junitxml += xml; just after line 157. now the XML produces:
`

`

Running a single test file is not possible.

When providing the location to a JavaScript (.js) file as the value of the argument "--tests", the following exception is thrown:

Error: Cannot find test directory '/Users/stephenmathieson/{...}/phantom-tests.js'.

This is due to your "validate" method (lines 61 through 67). You're throwing an error if the value of "tests" ends in ".js" and is not a file, which is expected. However, if the value of "tests" is an existing JavaScript file, an exception is thrown because it is not a directory.

A simple fix:

    if (this.options.tests === undefined) {
        throw new Error("You need to specify where your tests live, like: `--tests mytests.js`.");
    } else if (this.options.tests.indexOf('.js') !== -1) {
        if (!this.fs.isFile(this.options.tests)) {
            throw new Error("...");
        }
    } else {
        if (!this.fs.isDirectory(...)) {
            throw new Error("...");
        }
    }

I got the latest code. And run it on my local machine. I found that there is bug with the script that the phantomJS will not execute the QUnit.moduleDone event for the last module even it has ready run all the tests of it. I can't figure out how to fix it. Can somebody give me a help please? :)

hjwp commented Nov 6, 2013

Am I right in thinking this only finds tests in .js files? It won't find tests in .html files?

ChanderG commented May 3, 2014

As AgileAce says:

I've added this line junitxml += xml; just after line 157.

Needed to get valid (almost) xml.

When i am executing "...../phantomjs-2.1.1-windows\bin>phantomjs.exe qunit-runner.js --qunit ./qunit.js" i am getting error message TypeError: undefined is not an object (evaluating 'args.length') phantomjs://code/qunit-runner.js:30 in QUnitRunner.
I am using Phantomjs 2..1 and all the required files are in same directory i.e. bin of phantomjs.

moos commented Aug 18, 2016

phantom.args is no longer available in 2.x. You'll need

var system = require('system');
system.args.shift();  // skip first arg (runner)
var args = system.args;

var runner = new QUnitRunner(args);
runner.run()
