Question

@SelectPackages和@SelectClasses标签没有使用maven test命令进行解析。尽管它在IDE中工作正常。甚至我在pom.xml中尝试使用tag。

以下是代码段：

PaymentServiceTest.java

package xyz.howtoprogram.junit5.payment;

import static org.junit.jupiter.api.Assertions.assertEquals;

import org.junit.jupiter.api.Test;
import org.junit.platform.runner.JUnitPlatform;
import org.junit.runner.RunWith;

@RunWith(JUnitPlatform.class)
public class PaymentServiceTest {
  @Test
  public void doPaymentZeroAmount() {
    assertEquals(1, 1);
  }
}

UserFeatureSuiteTest.java

@RunWith(JUnitPlatform.class)
@SelectPackages("xyz.howtoprogram.junit5.payment")
public class UserFeatureSuiteTest {
}

它没有在包下运行任何测试用例。虽然它下面有一个测试用例。

xyz.howtoprogram.junit5.payment - ＆GT; PaymentServiceTest.java

Running xyz.howtoprogram.junit5.suite.UserFeatureSuiteTest
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0 sec - in xyz.howtoprogram.junit5.suite.UserFeatureSuiteTest.

即使我尝试更改pom.xml，例如添加'include'标记。

的pom.xml

以下是最终的POM，现在正在运作。

            <configuration>
                <includes>
                    <include>**/*SuiteTest.java</include>
                </includes>

        </plugin>

</build>

    <dependency>
        <groupId>org.junit.platform</groupId>

        <version>${junit.jupiter.version}</version>
        <scope>test</scope>
    </dependency>

所以输出是：

Answer 2

很抱歉让我感到困惑......我只是仔细看看你的代码并意识到你正试图混合两个概念。

您的测试代码使用JUnit 5 @Test进行注释。因此，此代码必须使用junit-jupiter-engine运行。该引擎 NOT 支持声明性套件，但是从maven-surefire-plugin读取配置。

@RunWith是一个JUnit4注释，在junit-jupiter-engine中被完全忽略。我不认为它会导致测试失败，但它也不会启用任何JUnit 5测试。在此上下文中，您放置在套件类中的@SelectPackages注释将仅帮助确定运行哪些JUnit 4测试 - 但您没有。

Answer 3

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configure Maven Surefire Plugin以使用其他模式进行测试类。

可能导致Maven无法工作的另一件事是所有测试都应该在以下文件夹中：

/my_application/src/test/java/MyFirstExampleTest.java

Here你可以看到一个很好的问题，可以概括你的问题，从我的答案的某些部分。你应该看看它。

在这里，您可以看到一个示例，说明您的pom.xml应该如何：

正如您在此配置文件中所看到的，您可以指定：


依赖关系：您需要JUnit的测试范围依赖项才能运行测试

在构建部分中，您将添加将运行测试及其依赖项的surefire插件

运行测试套件在junit5到maven

PaymentServiceTest.java

UserFeatureSuiteTest.java

的pom.xml
