Maven没有找到要运行的JUnit测试

我有一个maven程序，它编译得很好。当我运行mvn测试时，它不运行任何测试(在测试头下说没有要运行的测试。)

我用一个超级简单的设置重新创建了这个问题，我将在下面包括这个设置以及使用-X运行时的输出。

单元测试在eclipse中运行良好(使用默认的junit包和使用maven下载的junit.jar)。mvn test-compile也正确地创建了test-classes下的类。我在OSX 10.6.7上运行，使用Maven 3.0.2和java 1.6.0_24。

下面是目录结构:

/my_program/pom.xml
/my_program/src/main/java/ClassUnderTest.java
/my_program/src/test/java/ClassUnderTestTests.java

pom.xml:

ClassUnderTest.java:

public class ClassUnderTest {

    public int functionUnderTest(int n) {
        return n;
    }

}

    }

    @Test
    public void testFunctionUnderTest_testCase2() {
        Assert.assertEquals(2, o.functionUnderTest(2));
    }
}

mvn -X测试结束:

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:

<properties>
  <test>.... </test>
  ...
</properties>

然后取出来。

其他回答

我也有类似的问题，经过探索发现测试依赖导致了这个问题。从pom中删除测试依赖后(因为我不再需要它了)，它开始为我工作得很好。

    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.8</version>
        <scope>test</scope>
    </dependency>

检查一下(对于jUnit - 4.12和Eclipse surefire插件)

在依赖的POM.xml中添加所需的jUnit版本。Do Maven ->更新项目，以查看所需的jar导出项目。 Test类在src/ Test /java文件夹下和该文件夹的子目录下(或者可以在配置testSourceDirectory的POM中指定基本文件夹)。类名后面应该有“Test”字样。 测试类中的Test Method应该有注释@Test

如果您的测试类名不遵循标准命名约定(如上面的@axtavt突出显示的那样)，您需要在pom.xml中添加模式/类名，以便Maven选择test -

...
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <includes>
                    <include>**/*_UT.java</include>
                </includes>
            </configuration>
        </plugin>
    </plugins>
</build> 
...

/my_program/src/test/java/ClassUnderTestTests.java

应该是

/my_program/src/test/java/ClassUnderTestTest.java

Maven找到那些以Test结束或以Test开始的自动运行。

但是，你可以使用

mvn surefire:test -Dtest=ClassUnderTestTests.java

做你的测试

如果您用JUnit 4编写测试，并将JUnit 5依赖项添加到surefire插件，那么您的测试将无法运行。

在这种情况下，只需从surefire插件注释JUnit 5依赖项:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.19.1</version>
            <!--<dependencies>-->
                <!--<dependency>-->
                    <!--<groupId>org.junit.platform</groupId>-->
                    <!--<artifactId>junit-platform-surefire-provider</artifactId>-->
                    <!--<version>1.0.0</version>-->
                <!--</dependency>-->
                <!--<dependency>-->
                    <!--<groupId>org.junit.jupiter</groupId>-->
                    <!--<artifactId>junit-jupiter-engine</artifactId>-->
                    <!--<version>${junit.version}</version>-->
                <!--</dependency>-->
            <!--</dependencies>-->
        </plugin>
