* Speedups: remove dependency on c++ * Speedups: intset: handle malloc failing * Speedups: intset: fix corner case for int64 on 32bit systems original idea was to only use bucket->val if int<pointer, but we always have a union now anyway * Speedups: add size comment to player_set bucket configuration * test: more tests for LocationStore.find_item * test: require _speedups in CI This kind of tests that the build succeeds. * test: even more tests for LocationStore.find_item * Speedups: intset uniform comment style * Speedups: intset: avoid memory leak when realloc fails * Speedups: intset: make `gcc -pedantic -std=c99 -fanalyzer` without warnings Unnamed unions are not in C99, this got fixed. The overhead of setting count=0 is minimal or optimized-out and silences -fanalizer (see comment). * Speedups: don't leak memory in case of exception * Speedups: intset: validate alloc and free This won't happen in our cython, but it's still a good addition. * CI: add test framework for C/C++ code * CI: ctest: fix cwd * Speedups: intset: ignore msvc warning * Tests: intset: revert attempt at no-asan We solve this with env vars in ctest now, and this fails for msvc. * Test: cpp: docs: fix typo * Test: cpp: docs: fix another typo * Test: intset: proper bucket count for Negative test INTxx_MIN % 1 would not produce a negative number, so the test was flawed.

# C++ tests
|
|
|
|
Test framework for C and C++ code in AP.
|
|
|
|
## Adding a Test
|
|
|
|
### GoogleTest
|
|
|
|
Adding GoogleTests is as simple as creating a directory with
|
|
* one or more `test_*.cpp` files that define tests using
|
|
[GoogleTest API](https://google.github.io/googletest/)
|
|
* a `CMakeLists.txt` that adds the .cpp files to `test_default` target using
|
|
[target_sources](https://cmake.org/cmake/help/latest/command/target_sources.html)
|
|
|
|
### CTest
|
|
|
|
If either GoogleTest is not suitable for the test or the build flags / sources / libraries are incompatible,
|
|
you can add another CTest to the project using add_target and add_test, similar to how it's done for `test_default`.
|
|
|
|
## Running Tests
|
|
|
|
* Install [CMake](https://cmake.org/).
|
|
* Build and/or install GoogleTest and make sure
|
|
[CMake can find it](https://cmake.org/cmake/help/latest/module/FindGTest.html), or
|
|
[create a parent `CMakeLists.txt` that fetches GoogleTest](https://google.github.io/googletest/quickstart-cmake.html).
|
|
* Enter the directory with the top-most `CMakeLists.txt` and run
|
|
```sh
|
|
mkdir build
|
|
cmake -S . -B build/ -DCMAKE_BUILD_TYPE=Release
|
|
cmake --build build/ --config Release && \
|
|
ctest --test-dir build/ -C Release --output-on-failure
|
|
```
