# The LLVM libc unit test framework This directory contains a lightweight implementation of a [gtest](https://github.com/google/googletest) 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.
