Intellij测试通过，MVN测试失败 [英] Intellij tests pass, mvn test fails

问题描述

我正在开发一个Spring Boot应用程序. 我已经测试了@autowired serivces.当我在IntelliJ中运行它们时，所有测试均通过.但是，当我从命令行运行mvn test时，会抛出nullpointer-exceptions.

I am working on a spring-boot application. I have test, with @autowiredserivces. All tests pass when I run them in IntelliJ. However, when I run mvn testfrom command line, nullpointer-exceptions are thrown.

非常感谢您的帮助！

@ExtendWith(SpringExtension.class)
@SpringBootTest(classes = Application.class,
        webEnvironment = SpringBootTest.WebEnvironment.NONE)
public class CategoryServiceTest extends ServiceTestBase {

    @Autowired
    private CategoryService categoryService;


    @Test
    public void testNoCategory() {
        List<Category> categories = categoryService.getAllCategories(false);
        assertEquals(0, categories.size());
    }
    //...
}

应用程序类

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

在命令行中输出(使用服务的每个测试一个)

org.olaven.quizgame.services.QuizServiceTest.testQuizWithoutSubCategoryFails()  Time elapsed: 0 sec  <<< FAILURE!
java.lang.NullPointerException
    at org.olaven.quizgame.services.QuizServiceTest.testQuizWithoutSubCategoryFails(QuizServiceTest.java:219)

QuizServiceTest.java第217-220行

Long categoryId = categoryService.createCategory(getRandomString(10));
Long subCategoryId = categoryService.createSubCategory(categoryId, getRandomString(10));
Long quizId = quizService.createQuiz(subCategoryId, getRandomString(10), "1", "2", "3", "4", 0);

推荐答案

尝试将更新的maven-surefire-plugin版本添加到pom.xml中:

Try to add newer maven-surefire-plugin version into your pom.xml:

<build>
     <plugins>
         ....
         <plugin>
             <groupId>org.apache.maven.plugins</groupId>
             <artifactId>maven-surefire-plugin</artifactId>
             <version>2.22.0</version>
         </plugin>
         ....
     </plugins>
 </build>
