当断言失败时,FluentAssertions提供了一些选项来处理失败情况。以下是一些常见的处理方式: 抛出异常:可以使用Throw方法来验证代码是否抛出了特定类型的异常。例如,result.Should().Throw<Exception>()可以验证代码是否抛出了Exception类型的异常。 自定义错误消息:可以使用WithMessage方法来指定自定
然后我们使用 Throw() 方法来断言该方法是否抛出了 Exception 异常,并使用 WithMessage() 方法来断言异常消息是否为 "error"。如果方法未抛出预期的异常,该断言将抛出异常,测试失败。 # 嵌套断言 有时候我们希望测试一个对象的属性是否满足特定条件。FluentAssertions 允许我们使用嵌套断言来测试对象的属性。下面是一个...

The event monitor will now ignore all events that throw exceptions when subscribing (add) or unsubscribing (remove) them.Note, that if there is an exception in the add event accessor, the event cannot be asserted, as it cannot be subscribed successfully....
Hi 🙋♂️. I'm Nico Jansen, a manager at Info Support. For years, we've sponsored FluentAssertions, a comparable assertion library. My colleagues also contributed a lot of code to the project. Unfortunately, they have decided to change the...

The fluent interface provides aand()andor()method to group assertions. This is useful when you want to make multiple assertions at once and a singular combined error. useExeQue\FluentAssert\Assert;$assert= Assert::for('fizz buzz');// Using `and()` will throw an exception if any of the...
