Unit-testing (utest)

Detailed Description

Versions of gtest macros that run tests in a coroutine environment and other helpers.

There are the following extensions:

1. _MT ("multi-threaded") macro versions take 'thread_count' integer as the 3rd parameter at the test definition. It specifies the number of worker threads that should be created for the test. By default, there is only 1 worker thread, which should be enough for most tests;
2. GetThreadCount() method is available in the test scope.

Usage examples:

UTEST(Semaphore, PassAcrossCoroutines) {
    engine::Semaphore s{1};
    std::shared_lock guard{s};
 
    auto task = utils::Async("test", [guard = std::move(guard)] {});
    task.WaitFor(utest::kMaxTestWaitTime);
    EXPECT_TRUE(task.IsFinished());
}

UTEST_MT(SemaphoreLock, LockMoveCopyOwning, 2) {
    engine::Semaphore sem{1};
    engine::SemaphoreLock lock(sem);
    ASSERT_TRUE(lock.OwnsLock());
 
    const engine::SemaphoreLock move_here{std::move(lock)};
    // NOLINTNEXTLINE(bugprone-use-after-move,clang-analyzer-cplusplus.Move)
    EXPECT_FALSE(lock.OwnsLock());
    EXPECT_TRUE(move_here.OwnsLock());
}
