android - cucumber-android 无法在项目中找到步骤定义 (MissingStepDefinitionError)

Question

我正在尝试在我的 Android 项目中使用 Cucumber-JVM。
我可以很好地运行示例(android-test 和 cukeulator-test)。

当我将 cucumber-android 引入我自己的 Maven 项目时，我得到以下 MissingStepDefinitionError。就好像 cucumber-android 不知道在哪里可以找到它的步骤。最初我认为是 org.picocontainer.paranamer.NullParanamer 导致了这个问题，但是示例项目也有这个错误并且它们运行得很好。所以这可能是一条红鲱鱼。

如有任何帮助或建议，我们将不胜感激。

Answer 1

我能够通过反复试验找出问题所在。

首先尝试将我的步骤定义从 src/main 移动到 src/test 但这没有帮助。

最终起作用的是确保步骤定义不在用@CucumberOptions注释的同一个类中。这没有意义，因为这就是示例的设置方式并且它们可以正常工作。但是在我的项目中，如果步骤定义在带有选项注释的类中，则不会被拾取。同一个包中的另一个 Java 类就可以了。

有点奇怪。
