Question

我试图升级黄瓜以使用并行执行功能，最终导致报告门户出现问题。

在兼容性矩阵中表示：

黄瓜java和黄瓜junit的版本-4.0.0-4.2.6黄瓜代理4.0.0的测试版本

我尝试使用黄瓜剂4.0.0替换不同版本的黄瓜4.0.0、4.2.3、4.2.2、4.2.6 它说

cucumber.runtime.CucumberException：无法加载插件类： com.epam.reportportal.cucumber.ScenarioReporter。它没有实现 banana.api.Plugin

Answer 1

从Cucumber 4及更高版本开始，自定义插件需要实现Cucumber.api.event.EventListener或Cucumber.api.event.ConcurrentEventListener接口之一。其他人也可以实现cumulative.api.StepDefinitionReporter和/或cumulage.api.SummaryPrinter。这些反过来扩展了cucumber.api.Plugin接口。

您使用的插件实现了gherkin.formatter.Formatter和gherkin.formatter.Reporter接口

对此已经存在一个问题-https://github.com/reportportal/agent-java-cucumber/issues/10，并且在同一问题中给出的解决方案-https://github.com/reportportal/agent-java-cucumber/issues/10#issuecomment-438434717。

在github页面上还提到了不同黄瓜版本的兼容性表-https://github.com/reportportal/agent-java-cucumber#compatibility-matrix-for-cucumber-agents
