如何通过依赖注入使用空手道 (Picocontainer)

Question

我有一个项目，我使用黄瓜、rest-assured、selenium 和 Appium，我正在尝试将 API 测试转移到 Karate 并且无法将它与 pom.xml 中的 picocontainer 依赖项一起使用.

    org.picocontainer.injectors.AbstractInjector$UnsatisfiableDependenciesException: com.intuit.karate.ScriptEnv has unsatisfied dependency 'interface com.intuit.karate.cucumber.KarateReporter' for constructor 'public com.intuit.karate.ScriptEnv(java.lang.String,java.io.File,java.lang.String,java.lang.ClassLoader,com.intuit.karate.cucumber.KarateReporter)' from org.picocontainer.DefaultPicoContainer@66ac5762:11<|

How can I add karate setup with dependency injection like picocontainer.

Answer 1

空手道不支持 Cucumber DI，实际上也不需要它。

因为您可以很容易地调用 Java 代码和 re-use 如果需要：https://github.com/intuit/karate#calling-java

但我们鼓励您尽可能先学空手道，然后学 JS，这样您才能获得最大收益。
