# 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 featurful 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.
