使用DynamicNode并需要生命周期挂钩才能在所有测试完成后运行 [英] Using DynamicNode and need a lifecycle hook to run after all tests have completed

问题描述

我在一个动态生成测试并执行它们的框架中非常成功地使用了DynamicNode.

I'm using DynamicNode very successfully in a framework that dynamically generates tests and executes them.

现在，在所有DynamicNode集合执行之后，我需要执行一些代码.这可能意味着我只有一个JUnit5类，其中包含多个返回Iterable<DynamicNode>的方法，但是我只想在所有测试方法都完成后才运行某些东西.

Now I have a need to execute some code after all DynamicNode collections have executed. This can mean that I have a single JUnit5 class with multiple methods that return Iterable<DynamicNode>, but I want to run something only after all the test methods have completed.

有没有一种方法可以自动执行此操作?

Is there a way to do this automatically ?

理想情况下，我希望我的框架注入要自动执行的代码，而无需用户在方法上添加@AfterAll批注并编写一些额外的代码.

ideally I would like my framework to inject the code to be executed automatically, without the user needing to add a @AfterAll annotation on a method and write some extra code.

推荐答案

用@TestFactory注释的每个方法都参与默认的生命周期.这意味着在您的情况下，应使用@AfterAll带注释的方法来解决问题.

Each method that is annotated with @TestFactory takes part in the default lifecycle. That means in your case an @AfterAll annotated method should do the trick.

@AfterAll

@AfterAll

表示带注释的方法毕竟应该执行 @Test，@RepeatedTest，@ParameterizedTest和@TestFactory 当前类中的方法；类似于JUnit 4的@AfterClass. 此类方法是继承的(除非它们被隐藏或覆盖)，并且 必须是静态的(除非每类"测试实例生命周期是 使用).

Denotes that the annotated method should be executed after all @Test, @RepeatedTest, @ParameterizedTest, and @TestFactory methods in the current class; analogous to JUnit 4’s @AfterClass. Such methods are inherited (unless they are hidden or overridden) and must be static (unless the "per-class" test instance lifecycle is used).
