Surefire 重新运行失败的测试不起作用

问题描述

我想重新运行一个我知道会失败的测试，因为我正在尝试测试 Surefire 参数以重新运行失败的测试.我尝试使用这两个命令运行 Maven，但它们都没有按预期工作

I want to rerun a test that I know will fail cause I am trying to test the Surefire parameter for re-running the failing tests.I tried running Maven with these two commands neither of them works as expected

-Dsurefire.rerunFailingTestsCount=2 -Dtest=TestThatFails test

和

-Dsurefire.rerunFailingTestsCount=2 -Dtest=TestThatFails surefire:test

这是pom.xml

<dependency>
    <groupId>org.apache.maven.surefire</groupId>
    <artifactId>surefire-api</artifactId>
    <version>2.19.1</version>
</dependency>
<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>2.53.1</version>
</dependency>

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>

我原以为 Surefire 会在失败后重新启动测试，但 Maven 只是抛出此错误，我知道如何解决，但我希望重新运行测试.

I was expecting that Surefire would restart the test after failure but Maven just throws this error, which I know how to solve but I want the test to be rerun.

Results :

Tests in error:
  testA(selenium.services.TestThatWillFail): Element is not currently visible and so may not be interacted with(..)

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0

推荐答案

尽管文档中缺少该参数，但参数 rerunFailingTestsCount 是在 Maven Surefire 插件 2.18 版中引入的，如SUREFIRE-1087.由于您使用的是默认版本 2.12.4(来自 Super POM)，因此该选项不可用.

Although that is missing from the documentation, the parameter rerunFailingTestsCount was introduced in version 2.18 of the Maven Surefire Plugin, as mentioned in SUREFIRE-1087. Since you're using the default version of 2.12.4 (that comes from the Super POM), that option is not available.

因此，修复只是将 Surefire 版本更新到至少 2.18 的版本；例如，最新的，目前是 2.19.1:

Therefore, the fix is simply to update the Surefire version to a version that is at least 2.18; for example, the latest, which is currently 2.19.1:

<pluginManagement>
  <plugins>
    <plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.19.1</version>
    </plugin>
  </plugins>
</pluginManagement>

请注意，此参数仅适用于 JUnit 4+(这是您的情况，因为您使用的是 JUnit 4.12).

Note that this parameter only works with JUnit 4+ (which is your case, since you have JUnit 4.12).
