Is there any better alternative that you can propose? 回答1: Refer to Oracle's "Java Scripting

问题 Is there a way I can debug through the test in a similar way that I would debug a Java app using Maven? For example, if I set breakpoint in the implementstion of step and click on debug with next parameters of CL: mvn clean test -Dkarate.options="--tags ~@ignore" -Dtest=MainRunner -DforkCount=0 and I'm getting next errors: [INFO] --- maven-surefire-plugin:2.22.2:test (default-test) @ karateSberApi --- [WARNING] useSystemClassloader setting has no effect when not forking [INFO] Running
