Question

我有一个项目，我使用maven fail-safe插件来运行集成测试。我正在使用Maven + TestNG框架组合。出于项目目的，我早些时候修改了TestNG的默认 XML报告 来自定义项目需求。

我在 CustomReporter 类中实现了上述要求，该类扩展了TestNG的IReporter接口。之前我使用surefire插件来运行这些测试方法，并在surefire插件中添加listener mechanism按预期工作。

现在针对某些项目需求，我需要迁移到failsafe插件。所以我通过配置POM文件来绕过test surefire阶段执行。

 <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
            <skip>true</skip>
        </configuration>
</plugin>

然后我在POM文件中添加了failafe配置，如下所示;

 <

plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.12</version>
    <executions>
        <execution>
            <id>fail-safe-myplug</id>
            <phase>integration-test</phase>
            <goals>
                <goal>integration-test</goal>
            </goals>
            <configuration>
                <skip>false</skip> 
                    <properties>                
                        <property>  
                        <name>listener</name>
                            <value>com.CustomXmlReport</value>
                                </property>
                            </properties>
                            <includes>
                                <include>**/*Test.java</include>
                            </includes>                     
                        </configuration>
                    </execution>
                </executions>

            </plugin>

使用这个新的POM，使用failsafe插件的集成测试调用失败。以下是日志;

尽管我在failsafe阶段使用integration-test插件，但我得到了异常

使用以下命令配置TestNG：org.apache.maven。surefire。testng.conf.TestNGMapConfigurator @ab50cd org.apache.maven.surefire.util.`SurefireReflectionException

如何解决此问题？

注意：当我尝试使用surefire插件执行测试时，侦听器机制按预期工作。

实际上问题是，与Failsafe和TestNG版本的兼容性。我在TestNG 5.9v使用了failsafe plugin 2.12v。这是该问题的根本原因。

我将Failsafe版本降级为2.5v，问题得到了解决。
