JUnit 5-全局超时? [英] JUnit 5 -- global timeout?

问题描述

在JUnit 5中，对所有测试强制执行全局超时的最佳方法是什么?

In JUnit 5, what is the best way to enforce a global timeout for all tests?

我看到JUnit 4具有@Rule功能，但是在JUnit 5中已将其删除.我希望不必复制粘贴

I see that JUnit 4 has a @Rule feature, but this has been removed in JUnit 5. And I would prefer not to have to copy-paste assertTimeoutPreemptively for every test.

推荐答案

您提到了JUnit 4 @Rule ，它允许在每个测试类的基础上指定超时. JUnit 5.5在

You mentioned the JUnit 4 Timeout @Rule, which allows specifying timeouts on a per-test class basis. JUnit 5.5 has a direct equivalent as an experimental feature in the @Timeout annotation. This can be applied to the class level in the same manner as the JUnit 4 rule, in which case it applies to all tests within the class and its @Nested classes. It can also be applied to individual @Test or lifecycle (@BeforeAll, @BeforeEach, @AfterEach, or @AfterAll) methods.

根据 JUnit 5用户指南:

通过@Timeout批注，可以声明如果执行时间超过给定的持续时间，则测试，测试工厂，测试模板或生命周期方法应失败.持续时间的时间单位默认为秒，但可以配置.

The @Timeout annotation allows one to declare that a test, test factory, test template, or lifecycle method should fail if its execution time exceeds a given duration. The time unit for the duration defaults to seconds but is configurable.

[...]

要将相同的超时应用于测试类及其所有@Nested类中的所有测试方法，可以在类级别声明@Timeout批注.然后，它将被应用于该类及其@Nested类中的所有测试，测试工厂和测试模板方法，除非被特定方法或@Nested类上的@Timeout注释覆盖.请注意，在类级别声明的@Timeout注释不适用于生命周期方法.

To apply the same timeout to all test methods within a test class and all of its @Nested classes, you can declare the @Timeout annotation at the class level. It will then be applied to all test, test factory, and test template methods within that class and its @Nested classes unless overridden by a @Timeout annotation on a specific method or @Nested class. Please note that @Timeout annotations declared at the class level are not applied to lifecycle methods.
