TestNG - 带有故障安全插件的自定义报告器侦听器问题 [英] TestNG - Custom reporter listener issue with failsafe plugin

问题描述

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，之前我修改了 TestNG 的默认 XML 报告 以自定义项目需求.

I have a project in which I used maven fail-safe plugin to run the integration tests. I am using the Maven + TestNG framework combination. For the project purpose, earlier I have modified the TestNG's default XML Report to customize the project needs.

我在扩展 TestNG 的 IReporter 接口的 CustomReporter 类中实现了上述要求.之前我使用了surefire插件来运行这些测试方法，并且在surefire插件中添加了listener机制可以正常工作.

I implemented the above said requirement in a CustomReporter class which extends the TestNG's IReporterinterface. Earlier I used surefire plugin to run these test methods and adding the listener mechanism in the surefire plugin works as expected.

现在对于某些项目需求，我需要迁移到故障安全插件.所以我通过配置POM文件绕过了surefire的test阶段执行

Now for certain project needs, I need to migrate to failsafe plugin. So I bypassed the test phase execution of surefire by configuring the POM file.

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

然后我在 POM 文件中添加了故障安全配置，如下所示；

Then I have added the failsafe configuration in the POM file as below;

 <

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；

即使我在 integration-test 阶段使用了 failsafe 插件，我也遇到了异常

Eventhough I am using failsafe plugin in the integration-test phase, I am getting the exception

使用以下命令配置 TestNG:[e-mail].`SurefireReflectionException

Configuring TestNG with: org.apache.maven.surefire.testng.conf.TestNGMapConfigurator@ab50cd org.apache.maven.surefire.util.`SurefireReflectionException

如何解决这个问题?

注意:当我尝试使用 surefire 插件执行测试时，listener mechanishm 按预期工作.

Note : When I tried to execute the tests using surefire plugin, the listener mechanishm works as expected.

推荐答案

其实问题在于与 Failsafe 和 TestNG 版本的兼容性.我使用 TestNG 5.9v 和 failsafe plugin 2.12v.这是问题的根本原因.

Actually the issue is, the compatibility with Failsafe and TestNG versions. I was using TestNG 5.9v with failsafe plugin 2.12v. This is the root cause for the issue.

我将 Failsafe 版本降级到 2.5v，问题得到解决.

I downgraded the Failsafe version to 2.5v and the issue got resolved.
