如何使用 Google 测试捕获断言? [英] How to catch an assert with Google test?

问题描述

我正在使用 Google 测试框架编写一些单元测试.但是我想检查一些断言是否放置得很好并且有用.有没有办法在 Google 测试中捕获断言?

I'm programming some unit test with the Google test framework. But I want to check whether some asserts are well placed and are useful. Is there a way to catch an assert in Google test?

测试中的示例代码:

int factorial(int n){
    assert(n >= 0);
    //....
}

然后是测试:

#include <gtest/gtest.h>
TEST(FactorialTest,assertNegative){
    EXPECT_ANY_THROW({
         factorial(-1);
    });
}

但是 EXPECT_ANY_THROW 不会捕获断言，而只会捕获异常.我正在寻找捕获断言的解决方案.

But EXPECT_ANY_THROW doesn't catch the assert but only exceptions. I'm searching for a solution to catch asserts.

推荐答案

Google 测试提供 ASSERT_DEATH、EXPECT_DEATH 等相关宏.

Google test provides ASSERT_DEATH, EXPECT_DEATH and other related macros.

这个问题和什么是谷歌测试，死亡测试是彼此的答案.这是否会使它们重复?;-)

This question and What are Google Test, Death Tests are each other's answers. Does that make them duplicates, or not? ;-)
