Some test code was doing loose conversions caught by compiler warnings in the Fuchsia build. This included duplicated code in a few tests that was reconsolidated with the existing header file copy of the same functions. The MemoryMatcher abstraction presumes gtest-style matcher support, which is not available in Fuchsia's zxtest library. It's avoided in favor of simpler memory-comparing assertions.

The LLVM libc unit test framework
This directory contains a lightweight implementation of a gtest like unit test framework for LLVM libc.
Why not gtest?
While gtest is great, featureful and time tested, it uses the C and C++ standard libraries. Hence, using it to test LLVM libc (which is also an implementation of the C standard libraries) causes various kinds of mixup/conflict problems.
How is it different from gtest?
LLVM libc's unit test framework is much less featureful as compared to gtest. But, what is available strives to be exactly like gtest.
Will it be made as featureful as gtest in future?
It is not clear if LLVM libc needs/will need every feature of gtest. We only intend to extend it on an as needed basis. Hence, it might never be as featureful as gtest.
