谷歌測試

Google Test 是由 Google 維護的 C++測試框架。 它需要構建 gtest 庫並在構建測試用例檔案時將其連結到測試框架。

最小的例子

// main.cpp

#include <gtest/gtest.h>
#include <iostream>

// Google Test test cases are created using a C++ preprocessor macro
// Here, a "test suite" name and a specific "test name" are provided.
TEST(module_name, test_name) {
    std::cout << "Hello world!" << std::endl;
    // Google Test will also provide macros for assertions.
    ASSERT_EQ(1+1, 2);
}

// Google Test can be run manually from the main() function
// or, it can be linked to the gtest_main library for an already
// set-up main() function primed to accept Google Test test cases.
int main(int argc, char** argv) {
    ::testing::InitGoogleTest(&argc, argv);

    return RUN_ALL_TESTS();
}

// Build command: g++ main.cpp -lgtest
