如何在多个 Catch2 测试用例中检查相同的条件

Question

我必须在几个测试用例中检查某些条件（例如初始状态）。我不能在函数中使用 CHECK，如果可能的话，我想替换当前的宏。

#include "catch.hpp"

#define CHECK_INITIAL_STATE() \
    CHECK(first_condition); \
    CHECK(second_condition);

TEST_CASE("first_test") {
    CHECK_INITIAL_STATE();
    // do something
    // restore state
    CHECK_INITIAL_STATE();
}

Answer 1

Catch2 以非常优雅的方式内置了此功能：

TEST_CASE("first_test") {
    CHECK(first_condition);
    CHECK(second_condition);

    SECTION("do something 1") {
        // this test is executed after the code outside of the section
    }
    SECTION("do something 2") {
        // this test is executed after the code outside of the section
        // but without executing the previous section
    }
}
