########################################################### I created a Maven project with cucumber framework and wrote a feature file, step definitions, test runner and hooks file. When I run my test runner I am getting "io.cucumber.java.InvalidMethodSignatureException", when I import io.cucumber.java.before/after but my test is running when I import from junit, but @before and @after doesn't work in cucumber if we import from juint. I not understanding why I am getting InvalidMethodSignatureException. I tried providing order=0 for @Before annotation. It doesn't work Above is the code, please help me.

Answer 1

You get this issue because methods annotated with io.cucumber.java.Before have to be void.

In your example it returns WebDriver. This is why you get InvalidMethodSignatureException.
