I want to make Sham itself to throw Exceptions. Currently you need to use whatever testing framework you are using for asserting. This means that for example with PHPUnit your assertions will look something like this:
$this->assertTrue($stub->calls('method', 'param 1')->once());
This is too verbose.
To integrate with PHPUnit correctly I would need to throw
PHPUnit_Framework_AssertionFailedError exceptions. This would make Sham
assertions report correctly as failures, and not as errors. However, I don’t
want to integrate only with PHPUnit, I want Sham to be as simple and generic as
What we need is an
AssertionException class in PHP’s itself. This small
addition would make testing tools play nicely together. PHPUnit would extend
AssertionException and so would Sham. We would all have the same meaning for a
This kind of thing would be easy to implement in PHP, but as far as I know there is no way of implementing anything in PHP that would be included in PHP. That is, all the SPL classes are implemented in C.
Taking this a bit further, there should also be something in PHP that would throw
these AssertionErrors. For this I propose the
assert keyword. The assert
statement would look like this:
If the expression evaluates to false, an
AssertionException would be thrown.
assert(), the function, but it’s hideous.
Maybe I’ll pick up my dusty Extending and Embedding PHP someday and whip up a patch. Until then, any takers?
