无法识别带有 org.junit.Test 注释的测试

Question

每当我用 org.junit.Test 注释测试时，在 mvn test 或 mvn clean install 期间无法识别测试。但是当我用 org.junit.jupiter.api.Test; 注释时它被识别 pom.xml

有什么方法可以让 maven 提取带有 org.junit.Test 注释的测试吗？

更新：- 添加了完整的 pom.xml 以供参考我也在使用 powermockito 来存根我的静态方法。如果我还可以添加任何其他内容，请告诉我，以便帮助您调试问题

Answer 1

据我在 pom.xml 中所见，存在一些冗余依赖项。选择 org.junit.jupiter.api.Test 的原因是因为它是 Junit5 的一部分，并且作为 Maven 依赖项添加到 spring-boot-starter-test。基本上，您的问题是您使用的是 2 个不同版本的 junit - 4 和 5。

如果您想使用 junit 4，请删除依赖项 - spring-boot-starter-test 并试一试。

请告诉我结果。希望这有助于进一步调试！

Answer 2

我假设，你是运行它来自IDE，如果是这样，请检查你没有在"Run Configurations"下选择Junit5。您可以在此对话框中找到该选项，

希望这对您有所帮助，否则请告诉我。

Answer 3

其实你的问题就在这里

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

通过排除 junit-vintage-engine 你说你的应用程序中没有任何 junit4 测试用例。但事实并非如此....

因此无需删除整个依赖项....只需删除排除项，您的 junit4 测试用例将运行。

Answer 4

如果您想运行同时测试 JUnit4 和 JUnit5，您现在必须这样做：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>junit-4-5</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.6.2</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.junit.vintage</groupId>
            <artifactId>junit-vintage-engine</artifactId>
            <version>5.6.2</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>3.0.0-M4</version>
            </plugin>
        </plugins>
    </build>

</project>

控制台输出：

[INFO] --- maven-surefire-plugin:3.0.0-M4:test (default-test) @ junit-4-5 ---
[INFO] 
[INFO] -------------------------------------------------------
[INFO]  T E S T S
[INFO] -------------------------------------------------------
[INFO] Running pkg.JUnit5Test
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.053 s - in pkg.JUnit5Test
[INFO] Running pkg.JUnit4Test
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.035 s - in pkg.JUnit4Test
[INFO] 
[INFO] Results:
[INFO] 
[INFO] Tests run: 2, Failures: 0, Errors: 0, Skipped: 0

和测试：

import org.junit.Test;

public class JUnit4Test {
    @Test
    public void test() {

    }
}


import org.junit.jupiter.api.Test;

public class JUnit5Test {
    @Test
    public void test() {

    }
}

在 Surefire 和 Failsafe 的未来版本 3.0.0-M5 中，您会更容易，并且不需要引擎：

    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter-api</artifactId>
        <version>5.6.2</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.13</version>
        <scope>test</scope>
    </dependency>
