Maven Surefire 双重计数测试

Question

虽然我不太精通 Maven 生命周期，但我在过去三天阅读了大量文档，但没有发现任何显示构建周期、目标或我的插件与我遇到的问题之间的关系看到了。

我在使用最新的 Surefire 插件 (3.0.0-M1) 时遇到了一个奇怪的问题，我的单元测试成功完成但似乎运行ning 两次（或者可能只是被计算了两次？).

一些上下文 - 在我在此 POM 文件中指定任何插件或版本之前，Surefire 运行单独使用默认版本使用：

mvn clean package

我不知道为什么。我从来没有真正停下来问为什么会这样。它总是如此，所以我把它当作 g运行ted，现在它表现得很奇怪。这可能是我应得的。

这是运行的 POM 文件（删除了一些属性和分布）：

所以 - 没有提到 surefire 插件，但它运行无论如何我的测试。运行所有测试并返回 144 作为计数（正确）。一年多以来都是这样，但我添加了一些代码调整，现在我需要将其作为插件包含在内，因为我的测试需要一些环境变量，如下所示：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M1</version>
        <configuration>
            <environmentVariables>
                <env>dev</env>
                <ENV>DEV</ENV>
            </environmentVariables>
        </configuration>
</plugin>

但是现在当我运行我的测试套件时我得到了这个：

第一个问题是：我是不是疯了？当我不包含该插件时，当我什么都不做时，surefire 插件默认为运行ning（我什至不知道如何关闭它），当我包含它时，它似乎运行两次。我的其他插件之一运行没有广播它吗？这是一个我不引以为豪的问题。但是然后 - 如果我将插件作为一个行项目包含在我的 POM 中，但将其设置为 "default" 版本：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.12.4</version>
        <configuration>
            <environmentVariables>
                <env>dev</env>
                <ENV>DEV</ENV>
            </environmentVariables>
        </configuration>
</plugin>

我得到了预期的 144 计数和我的测试运行，因为它们具有所需的变量。那么最新版本的surefire可能有问题吗？或者只是我将它包含在其他包中的方式？

有人用这个新的 Surefire 遇到过这个问题吗？或者也许是这种插件组合？

Answer 1

请参阅此 answer to Maven: Lifecycle vs. Phase vs. Plugin vs. Goal 的 参考资料 部分，了解为什么插件运行在 Maven 构建期间没有声明它们。

关于您的双重测试的疯狂猜测：在您的第一张图片中，我们可以看到您正在运行宁 TestSuite。也许您的测试运行（或计数）一次通过此套件，一次单独进行。如果你 remove/disable 套房怎么办。
