| # 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. |
