Add a test suite

[watzon]

Currently we have access to one "test method" as far as I can tell, and that's assert. It's nice to have, but there's only so much you can do with it. It would be nice to have a more fully featured test suite built in so that we could do things like:

assert_eq(foo, bar)
assert_panics(im_broken())
assert_not_empty(some_array)
// etc etc

This would be extremely helpful, especially when it comes to debugging tests since currently assert doesn't actually tell you what the value was that made the assertion failed. It just panics and tells you the line.

assert_eq is already here (assert)
assert_non_empty is just assert some_array.len == 0

assert_panics I agree with.

[medvednikov]

doesn't actually tell you what the value was that made the assertion failed.

this will be fixed soon

I just figured something like this would require an assert_eq type function, unless it's all compiler magic. Either way that's the main thing I want. Saves a lot of debugging time.

Yes, this will be compiler magic :)

Assert is a builtin keyword.

I figured as much. Any reason to not keep assert but also have a test suite built on top of it that's a little more flexible and easy to modify? Compiler internals are a little harder to contribute to, especially for newcommers.
