[enhancement] add informal aliases for Expect tests.

[glennj]

equals, doesNotEqual
isGreaterThan, isLessThan, isGreaterThanOrEqual, isLessThanOrEqual
isNull, isNotNull
hasSameItemsAs
abortsWith, doesNotAbort

These look nice, shouldn't this also include isEqual and isNotEqual though?

This would un-deprecate abortsWith

[joshgoebel]

For completeness also isSameItemsAs? Thoughts?

[glennj]

Indeed, I missed that one.

Although I find toIncludeSameItemsAs pretty niche. Have you had circumstances where you need that kind of test? It strikes me that would be a time to write a Set class with an == method.

[joshgoebel]

I added things as needed so I bet it was used in one of the test suites... IIRC its useful for resolving indeterminate order results without having to sort() both sides [which is stupidly annoying] for equality. To me it seems a useful assertion for exactly that purpose, though perhaps there is a better name to be found?

[glennj]

No suggestions for improvement, except that wren needs a sorted() method that returns a new list, leaving the original untouched.

sorted() { this[0..-1].sort() }
sorted(comparer) { this[0..-1].sort(comparer) }

[joshgoebel]

Perhaps. :-)

I'd still hate to type sorted() everywhere. Seems like this is a problem a test library is well suited to solve for the user, no? :-)

You could open an issue on wren/wren.

Yes, I didn't add it for no reason. 🤪
