How to suppress Cucumber/Junit assertion stack trace

I have a cucumber scenario and the step uses assertEquals. My results report shows the stack trace which is not end user friendly. How can I suppress it

  Scenario: Add two numbers
    Given I have two inputs "3" and "2"
    When I add them
    Then the output should be "15"

junit

Solution

  • You're correct in observing that the default XML output (assuming you're not outputting to JSON or text, but you didn't say) from a Junit tests show stack traces for failed steps. This isn't actually a Cucumber thing. CucumberOptions won't help you here.

    You can:

    1. Use a different or custom Runner for your test and then setup a tag that controls what is included in the output, or what will be read by the CI software of your choosing. For example the Confulence API API for doing this tells how "debugger"
    2. Same type of deal for Ant Scripts to tweak the output, so that is doesn't show the output. A good Tutorial for learning how to use Any scripts to fire off your Cucumber JUnit Test is here.
    3. Other have build a custom formatter for JUnit by implementing XMLJUnitResultFormatter API, explained more here - How do I configure JUnit Ant task to only produce output on failures?

    Hope that gives you what you need.
