Maven报告它运行了测试套件，但没有运行任何JUnit测试

Question

我正在尝试使用JUnit从Maven测试一个Java应用程序。

我有以下POM（仅限相关部分）。

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <dependencies>
                    <dependency>
                        <groupId>org.apache.maven.surefire</groupId>
                        <artifactId>surefire-junit4</artifactId>
                        <version>2.7.2</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <includes>
                        <include>**/*Test.java</include>
                    </includes>
                </configuration>
  </plugin>

似乎正在运行“某事”。这是“mvn -X test”的输出：

Running TestSuite
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.769 sec

Results :


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

注意“运行TestSuite”。但是它仍然无法找到我的测试方法。我怀疑它可能与此有关：

[DEBUG] Adding to surefire test classpath: /home/julien/.m2/repository/org/apache/maven/surefire/surefire-testng/2.4.3/surefire-testng-2.4.3.jar
[DEBUG] Adding to surefire test classpath: /home/julien/.m2/repository/org/apache/maven/maven-artifact/2.0/maven-artifact-2.0.jar
[DEBUG] Adding to surefire test classpath: /home/julien/.m2/repository/org/codehaus/plexus/plexus-utils/1.0.4/plexus-utils-1.0.4.jar
[DEBUG] Adding to surefire test classpath: /home/julien/.m2/repository/junit/junit/3.8.1/junit-3.8.1.jar
[DEBUG] Adding to surefire test classpath: /home/julien/.m2/repository/org/apache/maven/surefire/surefire-api/2.4.3/surefire-api-2.4.3.jar

它说它正在使用Junit的3.8.1版本......

然而它继续说：

测试类路径：

 [DEBUG]   /home/julien/.m2/repository/junit/junit/4.8.2/junit-4.8.2.jar

我想知道“surefire test classpath”和“Test classpath”之间的区别是什么？

以下是我的测试方法的命名和注释方式：

 @Test
    public void test() {

...

它位于：

src/test/java/com/cheetah/web/pages

知道我错了什么吗？

这是有效的POM：

Answer 1

在maven中运行junit测试需要最少的设置。将junit添加到依赖项：

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.7</version>
    <scope>test</scope>
</dependency>

在src / test / java / com / cheetah / web / pages：

中创建一个类

public class FooTest {
    @Test
    public void writingToStdOut_succeeds() throws Exception {
        System.out.println("I work!");
    }
}

运行mvn test。就这样。在surefire插件中无需配置任何内容。战争项目与jar项目没有什么不同。如果你做了这两件事并且它不起作用，那么其他地方的东西就会被错误配置，我们可能需要看到整个pom，或者更好的是effective pom来告诉你发生了什么。

请注意，Surefire只会运行testng测试或junit测试，但不会同时运行。

Answer 2

只是提到每个人都已经知道的事情，但仍然一次又一次地抓住了我。请记住，有一个命名约定，将会是什么样的测试＆＃34;看到＆＃34;如果您没有正确命名测试类，则会被忽略。

运行

mvn -X test

告诉我们（裁减）：

[DEBUG] Configuring mojo 'org.apache.maven.plugins:maven-surefire-plugin:2.19.1:test' with basic configurator -->
[DEBUG]   (s) additionalClasspathElements = []
...
[DEBUG]   (s) excludes = [**/Abstract*.java]
[DEBUG]   (s) includes = [**/*Tests.java, **/*Test.java]

因此，默认情况下，只有结束＆＃34; Test.java＆＃34;或者＆＃34; Tests.java＆＃34;将被接走。

Answer 3

在我的情况下问题是maven版本依赖。我手动添加了它，我犯了一个错误。

提醒：

您应该始终通过＆＃34; Insert Dependency＆＃34;添加依赖项。菜单。它可以通过使用快捷键＆＃34; crtl＆＃34; +＆＃34; space＆＃34;来显示。当光标位于xml文件中的<dependency>和</dependency>之间时。当你进入＆＃34;选择依赖＆＃34;菜单输入＆＃34; junit＆＃34;在＆＃34;输入......＆＃34;文本框并选择您的junit版本。点击＆＃34; ok＆＃34;您的依赖项将自动添加。这有助于避免手动输入错误版本的问题。
