Maven没有findJUnittesting运行
我有一个maven程序，编译得很好。 当我运行mvn test它不会运行任何testing（在TESTs头下说There are no tests to run. ）。
我已经用一个超级简单的设置重新创build了这个问题，我将在下面包括以及用-X运行时的输出。
unit testing在eclipse中运行良好（包括默认的junit包，以及包含由maven下载的junit.jar）。 另外mvn test-compile正确地创build了testing类下的类。 我正在使用Maven 3.0.2和java 1.6.0_24在OSX 10.6.7上运行此操作。
这是目录结构：
/my_program/pom.xml /my_program/src/main/java/ClassUnderTest.java /my_program/src/test/java/ClassUnderTestTests.java
pom.xml中：
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>my_group</groupId> <artifactId>my_program</artifactId> <packaging>jar</packaging> <version>1.0-SNAPSHOT</version> <name>My Program</name> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.1</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> </plugins> </build> </project>
ClassUnderTest.java：
public class ClassUnderTest { public int functionUnderTest(int n) { return n; } }
ClassUnderTestTests.java：
import org.junit.Assert; import org.junit.Before; import org.junit.Test; public class ClassUnderTestTests { private ClassUnderTest o; @Before public void setUp() { o = new ClassUnderTest(); } @Test public void testFunctionUnderTest_testCase1() { Assert.assertEquals(1, o.functionUnderTest(1)); } @Test public void testFunctionUnderTest_testCase2() { Assert.assertEquals(2, o.functionUnderTest(2)); } }
mvn -Xtesting结束：

默认情况下Maven在查找要运行的testing时使用以下命名约定：
-
Test* -
*Test -
*TestCase
你的testing类不遵循这些约定。 您应该重新命名它或者configurationMaven Surefire插件来为testing类使用另一种模式。
我还发现unit testing代码应放在testing文件夹下，如果放在主文件夹下面，则不能将其识别为testing类。 例如。
错误
/my_program/src/main/java/NotTest.java
对
/my_program/src/test/java/MyTest.java
另外一件事情，如果模块的包装没有被正确的声明，可能会导致Maven找不到testing。
在最近的情况下，有人有<packaging>pom</packaging> ，我的testing从未跑。 我把它改成<packaging>jar</packaging> ，现在工作正常。
此外，请检查您的testing类目录（例如src / test / java）是否对应于<build>属性下的pom.xml中属性<testSourceDirectory>中列出的目录。 花了我一段时间才发现。
检查（对于jUnit – 4.12和Eclipse的surefire插件）
- 在依赖项中添加POM.xml中所需的jUnit版本。 做Maven – >更新项目，以查看在项目中导出所需的jar子。
- testing类位于文件夹src / test / java和该文件夹的子目录下（或者可以在configurationtestSourceDirectory中的POM中指定基础文件夹）。 class级名称应该有“Test”字样。
- testing类中的testing方法应该有@Test注释
如果你有一个共享的Java / Groovy应用程序，并且你所有的都是Groovyunit testing，那么Maven将不会find任何testing。 这可以通过在src / test / java下添加一个unit testing来解决。
如果您使用“抽象”前缀进行testing，则会被默认忽略。
如果项目有<packaging>pom</packaging> Maven将不会运行您的testing
您需要将包装设置为jar（或其他一些java artefacttypes）以供testing运行： <packaging>jar</packaging>
我也有类似的问题，经过探索发现testng的依赖是造成这个问题。 从pom中删除testng依赖项（因为我不再需要它），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>
不运行testing用例的另一个原因发生在我身上 – 为了完全不同的目的，我有一个名为“test”的属性，但是它干扰了surefire插件。 因此，请检查您的POM：
<properties> <test>.... </test> ... </properties>
并删除它。
junitArtifactName也可能是如果使用的JUnit不是标准（ junit:junit ），但是例如…
<dependency> <groupId>org.eclipse.orbit</groupId> <artifactId>org.junit</artifactId> <version>4.11.0</version> <type>bundle</type> <scope>test</scope> </dependency>
