Azure DevOps流水线中maven-surefire-plugin触发TestNG测试失败

本地IntelliJ中可正常运行TestNG测试用例，但在Azure DevOps流水线执行maven-surefire-plugin:3.0.0-M7的test目标时失败，报错无法在类路径中找到WfmsgFunctionalitiesSmokeTestcases.WfmsgSimpleLoginTest类。

解决方案 #

• 确保编译步骤执行：将流水线的maven goals改为clean compile test，强制先编译生成class文件，避免因依赖缺失导致测试类未被编译到classpath中。
• 校验TestNG配置文件：检查testng.xml中配置的类名WfmsgFunctionalitiesSmokeTestcases.WfmsgSimpleLoginTest是否与实际代码的包名、类名完全一致，注意大小写和拼写（即使Windows系统不区分大小写，编译后的class文件路径仍需严格匹配）。
• 配置maven-surefire-plugin：在pom.xml中明确指定TestNG的测试套件文件路径，确保插件能正确找到测试类，示例配置：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.0.0-M7</version>
            <configuration>
                <suiteXmlFiles>
                    <suiteXmlFile>src/test/resources/testng.xml</suiteXmlFile>
                </suiteXmlFiles>
            </configuration>
        </plugin>
    </plugins>
</build>

• 确认工作目录与pom路径：检查流水线中mavenPomFile的路径是否正确，如果pom.xml不在代码仓库根目录，需调整为相对路径（如./submodule/pom.xml）。
• 统一JDK版本：确保本地开发使用的JDK版本与流水线指定的1.8一致，避免因版本差异导致编译后的class文件不兼容。
