#[test] fn is_true_when_even() { assert!(is_even(4)); } #[test] fn is_false_when_odd() { assert!(!is_even(5)); } } assert!(is_even(4)); uses the assert! macro to ensure that is_even(4) returns true. If is_even(4) returns false, the test will fail, indicating a...
assert_eq! 宏: assert_eq!宏用于比较两个值是否相等,如果不相等,则会触发断言失败。 示例使用assert_eq!宏: rustCopy code fn main() { letx=5;lety=3+2;assert_eq!(x, y, "x and y must be equal"); // 如果 x 和 y 不相等,则会触发断言失败println!("x and y are equal");} 在上面...
Right nowassertandassert_eqhave specific parse code to make sure we parse the correct number of arguments. This has a few issues: Not passing the correct number of arguments leads to a parsing error, which might be more confusing than "wrong number of arguments" If the number of arguments ...

gtest 如何输出内容到控制台 android gtest assert,介绍gtest是谷歌开发的用来做C++单元测试的测试框架基本概念使用gtest,你就需要写断言(assertions),用来检查一个表达式是否为true。断言的结果有三个:正确、非致命错误、致命错误。如果出现致命错误,就会退出当前函数
