Maven does not find JUnit tests to run
我有一个Maven程序，它编译得很好。当我运行

默认情况下，Maven在查找要运行的测试时使用以下命名约定：
Test* *Test *TestCase
您的测试类不遵循这些约定。您应该重命名它，或者配置maven-surefire插件为测试类使用另一个模式。
我还发现单元测试代码应该放在测试文件夹下，如果把它放在主文件夹下，它就不能被识别为测试类。如。
错误的
1 | /my_program/src/main/java/NotTest.java |
赖特
1 | /my_program/src/test/java/MyTest.java |
如果模块的包装声明不正确，另一件事可能会导致Maven找不到测试。
在最近的一个案例中，有人使用了
更新：
正如@scottyseus在评论中所说，从Maven Surefire 2.22.0开始，以下就足够了：
1 2 3 4 5 | <plugin> <groupId>org.apache.maven.plugins</groupId> maven-surefire-plugin</artifactId> <version>2.22.1</version> </plugin> |
在使用JUnit5时，我遇到了同样的问题。Maven Surefire需要一个插件来运行JUnit 5测试。将此添加到我们的
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <plugin> <groupId>org.apache.maven.plugins</groupId> maven-surefire-plugin</artifactId> <version>2.21.0</version> <dependencies> <dependency> <groupId>org.junit.platform</groupId> junit-platform-surefire-provider</artifactId> <version>1.2.0-M1</version> </dependency> <dependency> <groupId>org.junit.jupiter</groupId> junit-jupiter-engine</artifactId> <version>5.2.0-M1</version> </dependency> </dependencies> </plugin> |
来源：https://junit.org/junit5/docs/current/user-guide/运行测试构建maven
此外，检查您的测试类目录(例如SRC/Test/Java)是否对应于在EDOCX1×4属性中的POM.XML中的属性EDOCX1 3中列出的目录。我花了一段时间才找到那个。
检查(对于JUnit-4.12和Eclipse Surefire插件)
如果项目有
您需要将包装设置为JAR(或其他一些Java人工制品类型)，以便运行测试：EDCOX1×6
如果在测试前面加上"abstract"，默认情况下也会忽略它。
如果你有一个共享的Java/Groovy应用程序，所有的都是Groovy单元测试，那么Maven就不会找到任何测试。这可以通过在SRC/Test/JAVA下添加一个单元测试来固定。
我也有类似的问题，在研究发现testng依赖性导致了这个问题之后。在从pom中删除了testng依赖项之后(因为我不再需要它)，它开始对我起作用了。
1 2 3 4 5 6 | <dependency> <groupId>org.testng</groupId> testng</artifactId> <version>6.8</version> <scope>test</scope> </dependency> |
这些答案中的许多在过去对我非常有用，但我想添加一个额外的场景，这让我花费了一些时间，因为它可能在将来帮助其他人：
确保测试类和方法是公共的。
我的问题是我使用的是我的IDE(Intellij)的自动测试类/方法生成功能，出于某种原因，它将它们创建为包私有。我发现这比人们想象的要容易错过。
1 | /my_program/src/test/java/ClassUnderTestTests.java |
应该是
1 | /my_program/src/test/java/ClassUnderTestTest.java |
Maven会找到这些结束测试或从测试开始自动运行。
但是，您可以使用
1 | mvn surefire:test -Dtest=ClassUnderTestTests.java |
运行测试。
如果测试类名不遵循标准命名约定(如上面@axtavt所强调的那样)，则需要在
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | ... <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> maven-surefire-plugin</artifactId> <configuration> <includes> <include>**/*_UT.java</include> </includes> </configuration> </plugin> </plugins> </build> ... |
另一个不运行测试用例的原因发生在我身上——我有一个名为"test"的属性，用于完全不同的目的，但它干扰了Surefire插件。因此，请检查您的POM：
1 2 3 4 | <properties> <test>.... </test> ... </properties> |
把它拿走。
还有一个提示(除了前面的答案之外)：
在Eclipse中，转到项目的属性>单击
"This page allows you to manage launch configurations with the
currently selected resource"
在这里，您可以添加(新的…)或删除(删除)您在项目中的任何JUnit(JUnit)测试(在
如果您已经在JUnit4中编写了测试并向Surefire插件添加了JUnit 5依赖项，那么您的测试将不会运行。
在这种情况下，只需注释来自SureFire插件的JUnit 5依赖项：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <plugin> <groupId>org.apache.maven.plugins</groupId> maven-surefire-plugin</artifactId> <version>2.19.1</version> <!--<dependencies>--> <!--<dependency>--> <!--<groupId>org.junit.platform</groupId>--> <!--junit-platform-surefire-provider</artifactId>--> <!--<version>1.0.0</version>--> <!--</dependency>--> <!--<dependency>--> <!--<groupId>org.junit.jupiter</groupId>--> <!--junit-jupiter-engine</artifactId>--> <!--<version>${junit.version}</version>--> <!--</dependency>--> <!--</dependencies>--> </plugin> |
在我的例子中，它添加了JUnit Vintage引擎，使其与旧版本的JUnit测试兼容，并可以运行它们。当我使用JUnit 5时。
1 2 3 4 5 | <dependency> <groupId>org.junit.vintage</groupId> junit-vintage-engine</artifactId> <scope>test</scope> </dependency> |
我也面临同样的问题，它通过在pom.xml中进行以下更改来解决：
1 2 | <build> <testSourceDirectory>test</testSourceDirectory> |
…
改为：
1 2 | <build> <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory> |
