Re: [Simpletest-support] customized assert methods?

[T.J.Hunt <t.j...@op...>]

The right way to do extensions like this is to create a new Expectation class. For example like https://github.com/moodle/moodle/blob/master/lib/simpletestlib.php#L105.

You can then use that as

$this->assert(new MyExpectation($parameters), $value);

That is the best way for tests you will want to reuse a lot. In other situations, a simple helper method is fine, but as you say, the default display is unhelpful. You can improve the display with a custom reporter. For example: https://github.com/moodle/moodle/blob/master/admin/report/unittest/ex_reporter.php#L160. That does a good job of showing just the interesting bits of the stack-trace, but not all the layers of the simpletest library.

All that code is GPL, so you can copy it if you are working to a suitable open source license.

Tim.

Subject: [Simpletest-support] customized assert methods?

Hi - I've been using Simpletest successfully and happily for a few years --
thanks -- and now want to wade in a little deeper.

In particular, I'd like to write some customized assertions, for instance

function assertLoginSuccessful($userName, $passWord)
{
        $this->setField('username',$userName);
        $this->setField('password',$passWord);
        $this->click('Login');
        return $this->assertText('Login successful!');
}

This works fine, but I'd like one more thing - if the assertText fails, I'd
like to see the line where assertLoginSuccessful was called.

It looks like I could hack this together myself by calling the assert method
directly, but then it seems I have to recreate assertText.

What's the right way to create new assert methods that behave like the
built-in ones, and also build on the built-in ones?

Thanks.
