在IntelliJ中运行Cucumber测试的IncompatibleClassChangeError

当我在IntelliJ中运行黄瓜测试功能时,它显示的是带有堆栈跟踪的IncompatibleClassChangeError:

Empty test suite.

这是IntelliJ IDEA 2018.1.4 (Ultimate Edition), Build #IU-181.5087.20,与Cucumber for Java version 181.5087.20

如问题#1392中所述

这是由IDEA的CucumberJvm2SMFormatter引起的.它是Cucumber2的格式化程序,在Cucumber 3中遇到了一个突破性的变化.

最简单的解决方法是--plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvm2SMFormatter从运行配置中删除程序参数.

这是在最新版本中解决的.

您可以重新创建配置(因此它将自动更新),或者您可以使用替换程序参数

--plugin org.jetbrains.plugins.cucumber.java.run.CucumberJvm3SMFormatter

旧版本的插件与黄瓜java版本3及更高版本不兼容.如果您遇到那个问题,可以更新build.gradle以明确指定版本2:

dependencies {
    ...
    testCompile 'io.cucumber:cucumber-java8:2.+'
}
