尝试使用Junit和Spring启动Web应用程序TESET时出错

发布于 2025-01-19 05:34:37 字数 7605 浏览 0 评论 0原文

我正在尝试测试 java spring web 应用程序，特别是我想尝试一些注入到应用程序上下文中的类。为了做到这一点，我发现使用 @SpringBootTest 注释我可以获得应用程序上下文。我想创建一个简单的测试来验证我是否确实可以使用它。我对以下测试用例有问题：

@TestMethodOrder(OrderAnnotation.class)
@SpringBootTest
class ProvaContext {

@Autowired
protected ApplicationContext apt;

@Test
@Order(0)
void test1() {
    assertNotNull(apt);
}
@Test
@Order(0)
void test2() {
    apt=ContextLoader.getCurrentWebApplicationContext();
    assertNotNull(apt);
}

}

当我启动服务器并尝试使用 eclipse 运行 junit 测试时，我收到此错误：

我无法找出问题。 pom.xml 文件具有以下依赖项：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <version>2.6.1</version>

如果没有 @SpringBootTest 注解，测试将运行，但 viriable apt 为 null。谢谢

i'm trying to test a java spring web application and in particular i want to try some class that are injected in the application context. In order to do this i've found thate using the @SpringBootTest annotation i can obtain the application context. I wanted to create a simplet test to verify that i can actualy use it. I have a problem with the following test case:

@TestMethodOrder(OrderAnnotation.class)
@SpringBootTest
class ProvaContext {

@Autowired
protected ApplicationContext apt;

@Test
@Order(0)
void test1() {
    assertNotNull(apt);
}
@Test
@Order(0)
void test2() {
    apt=ContextLoader.getCurrentWebApplicationContext();
    assertNotNull(apt);
}

}

When i start the server and try to run junit test with eclipse i get this error:

I can't figure out the problem. The pom.xml file has the following dependencies:

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <version>2.6.1</version>
        <scope>test</scope>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter-api -->
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>

        <scope>test</scope>
    </dependency>
</dependencies>

Without the @SpringBootTest annotation the test run but the viriable apt is null. Thanks
