Renaming test functions?

[sethaxen]

Currently we have fails(f) and errors(f). I wonder if it would make more sense to rename these to test_fails(f) and test_errors(f), similar to the @test_throws, @test_broken macros provided by Test.

Perhaps even better, it would simplify user code if we make these macros so users could call @test_fails f(...) and @test_errors f(...).

Here's some discussion on why they weren't macros to begin with:
JuliaDiff/ChainRulesTestUtils.jl#60 (comment)

the macro looks like @test_throws and @test_broken
but it does not at all work like those do.

@test_throws catchs the exception.
@test_broken x is very similar to @test !x + some extra stuff

I would worry that people might think @test_failure x is the same as same as @test !x
