英文:
Maven won't run JUnit5 tests
问题
以下是翻译好的部分：
（顺便说一句：是的，我在我的 pom 中包含了 Maven surefire 插件。）
我无法说服 Maven 运行我的 JUnit5 测试。
- 我正在使用 Maven surefire 插件版本 2.22。
- 我尝试将 surefire 插件降级到 2.19。
- 我正在使用与另一个正常运行的项目相同的依赖项和插件。
- 如果我将项目导入 Eclipse，Eclipse 可以找到并执行测试。
- 测试的类文件，app.AppTest.class，位于目录 target\test-classes\app 中。
- 我没有从 Maven 获取任何错误消息；它只是说“Tests run: 0, Failures: 0, Errors: 0, Skipped: 0”。
我在下面包含了我的 pom 的内容。有人可以告诉我我做错了什么吗？谢谢帮助。

(BTW: Yes, I am including the Maven surefire plugin in my pom.)
I can't persuade Maven to run my JUnit5 tests.
- I am using the Maven surefire plugin version 2.22
- I tried downgrading the surefire plugin to 2.19
- I'm using the same dependencies and plugins as another project which runs fine
- If I import the project into eclipse, eclipse finds and executes the tests
- The class file for the test, app.AppTest.class, is in directory target\test-classes\app
- I don't get any error messages from Maven; it just says "Tests run: 0, Failures: 0, Errors: 0, Skipped: 0"
I am including the contents of my pom, below. Can anyone tell me what I'm doing wrong? Thanks for the help.

也许你的代码导入了错误的Test注解；org.junit.Test，org.testng.annotations.Test，...
应该导入org.junit.jupiter.api.Test。
package app;
import static org.junit.jupiter.api.Assertions.fail;
import org.junit.jupiter.api.Test;
public class AppTest {
@Test
void test() {
fail("Not yet implemented");
}
}
英文:
Maybe your code imports wrong Test annotation; org.junit.Test, org.testng.annotations.Test, ...
org.junit.jupiter.api.Test should be imported.
package app;
import static org.junit.jupiter.api.Assertions.fail;
import org.junit.jupiter.api.Test;
public class AppTest {
@Test
void test() {
fail("Not yet implemented");
}
}

似乎您错过了测试方法的注解。只需将您的代码调整为：
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.Test;
import java.net.URL;
import javax.swing.JOptionPane;
class AppTest
{
@Test
void test()
{
System.out.println("*************");
URL resURL = getClass().getClassLoader().getResource("ResFile.txt");
System.out.println(resURL);
assertNotNull(resURL);
if (resURL != null)
{
System.out.println(resURL.getPath());
}
}
}
英文:
It seems that you missed the annotation on your test methods. Just adapt your code to:
import static org.junit.jupiter.api.Assertions.*;
import org.junit.jupiter.api.Test;
import java.net.URL;
import javax.swing.JOptionPane;
class AppTest
{
@Test
void test()
{
System.out.println( "*************" );
URL resURL = getClass().getClassLoader().getResource( "ResFile.txt" );
System.out.println( resURL );
assertNotNull( resURL );
if ( resURL != null )
{
System.out.println( resURL.getPath() );
}
}
}

参数由Surefire插件（自2.2版本起）使用，并且值得仔细检查，以考虑项目目录结构：
testSourceDirectory：测试源代码目录，包含测试类源代码。
默认值为：${project.build.testSourceDirectory}（默认值：src/test/java）。
classesDirectory（用于测试的生成类）。
默认值为：${project.build.outputDirectory}（默认值：target/classes文件夹）。
要在pom.xml中更改默认值：
```xml
<build>
<testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
-> 修改为：
<build>
<testSourceDirectory>${project.basedir}/myPath</testSourceDirectory>
更多信息请参考：http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html

<summary>英文:</summary>
Parameters used by Surefire plugin (since 2.2) and worth double checking taking into account the project directory structure:
testSourceDirectory: the test source directory containing test class sources.
Default value is: ${project.build.testSourceDirectory} (default: src/test/java).
classesDirectory (for generated classes being tested).
Default value is: ${project.build.outputDirectory} (default: target/classes folder).
To change the defaults in pom.xml:
<build>
<testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
->
<build>
<testSourceDirectory>${project.basedir}/myPath</testSourceDirectory>
