This directory contains a lightweight implementation of a gtest like unit test framework for LLVM libc.
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.
LLVM libc's unit test framework is much less featureful as compared to gtest. But, what is available strives to be exactly like gtest.
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.
