JUnit的@TestMethodOrder注释不起作用

Question

我在进行以下集成测试时遇到问题

import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.TestMethodOrder;
import org.junit.jupiter.api.MethodOrderer.OrderAnnotation;

@SpringBootTest
@ActiveProfiles("test")
@TestMethodOrder(OrderAnnotation.classs)
public class FooServiceIT {
    @Test
    @Order(1)
    void testUploadSuccess() { ... }
    @Test
    @Order(2)
    void testDownloadSuccess() { ... }
    @Test
    @Order(3)
    void testDeleteSuccess() { ... }
}

我希望在运行测试时，执行顺序为1、2、3，但由于某种原因，实际的执行顺序为2、3、1。

Tbh，我不知道为什么注释不起作用。我正在将Spring Boot 2.1.3与JUnit 5.4一起使用。

Answer 1

您需要正确配置您的IDE。

需求

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.4.0</version>
</dependency>

请勿使用提供您的IDE的JUnit 5。如果将其添加为库，您将获得：

No tests found for with test runner 'JUnit 5' 
==================== and this exception ===================
TestEngine with ID 'junit-vintage' failed to discover tests
java.lang.SecurityException: class "org.junit.jupiter.api.TestMethodOrder"'s signer information does not match signer information of other classes in the same package

因此只包括提到的依赖项，您的代码将按预期工作：

import org.junit.jupiter.api.MethodOrderer;
import org.junit.jupiter.api.Order;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.TestMethodOrder;

@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
public class FooServiceIT {

    @Test
    @Order(1)
    public void testUploadSuccess() {
        System.out.println("1");
    }

    @Test
    @Order(2)
    public void testDownloadSuccess() {
        System.out.println("2");
    }

    @Test
    @Order(3)
    public void testDeleteSuccess() {
        System.out.println("3");
    }
}

JUnit结果：

1
2
3

您需要正确配置pom.xml。见我的：

<properties>
    <!-- Dependency versions -->
    <junit.jupiter.version>5.6.0</junit.jupiter.version>
    <maven-surefire-plugin.version>3.0.0-M4</maven-surefire-plugin.version>

    <!-- Java 10 -->
    <maven.compiler.source>1.10</maven.compiler.source>
    <maven.compiler.target>1.10</maven.compiler.target>

    <!-- Encoding -->
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>

<!-- Jupiter API for writing tests -->
<dependencies>
    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-engine</artifactId>
        <version>${junit.jupiter.version}</version>
        <scope>test</scope>
    </dependency>
</dependencies>

<!-- Maven Surefire plugin to run tests -->
<build>
    <plugins>
        <!-- plugin to run test cases from maven -->
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>${maven-surefire-plugin.version}</version>
        </plugin>
        <!-- Maven plugin to use perticular java version to compile code -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>${maven.compiler.source}</source>
                <target>${maven.compiler.target}</target>
            </configuration>
        </plugin>
    </plugins>
</build>

现在，您的Junit 5注释必须正确运行

根据先前推荐的解决方案应用所有设置后。我仍然有相同的反向或随机@ order执行。

Pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.3.RELEASE</version>
</parent>

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

<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter-engine</artifactId>
    <version>5.4.0</version>
    <scope>test</scope>
</dependency>

Maven依赖树：

mvn dependency:tree -Dverbose -Dincludes=org.junit.jupiter:junit-jupiter-engine

[INFO] com.personalitytest.demo:personalitytest:jar:1.0-SNAPSHOT
[INFO] \- org.junit.jupiter:junit-jupiter-engine:jar:5.4.0:test

JUnit测试：

@SpringBootTest
@ActiveProfiles("test")
@TestMethodOrder(MethodOrderer.OrderAnnotation.class)
public class JUnitOrderTest {

    private static final Logger log = LoggerFactory.getLogger(JUnitOrderTest.class);

    @Test
    @Order(1)
    public void testUploadSuccess() {
        log.info("Junit - Order 1");
    }

    @Test
    @Order(2)
    public void testDownloadSuccess() {
        log.info("Junit - Order 2");
    }

    @Test
    @Order(3)
    public void testDeleteSuccess() {
        log.info("Junit - Order 3");
    }
}

输出：

Running com.personalitytest.demo.security.JUnitOrderTest
08:48:35.470 [main] INFO com.personalitytest.demo.security.JUnitOrderTest - Junit - Order 2
08:48:35.480 [main] INFO com.personalitytest.demo.security.JUnitOrderTest - Junit - Order 3
08:48:35.481 [main] INFO com.personalitytest.demo.security.JUnitOrderTest - Junit - Order 1

来自文档https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/TestMethodOrder.html

 @TestMethodOrder(MethodOrderer.OrderAnnotation.class)
 class OrderedTests {

     @Test
     @Order(1)
     void nullValues() {}

     @Test
     @Order(2)
     void emptyValues() {}

     @Test
     @Order(3)
     void validValues() {}
 }
