When karate-config.js fails it prints error for each feature

问题

Karate-Netty version 0.9.2

Whenever my karate-config.js evaluation fails it prints:

16:49:28.753 [ForkJoinPool-1-worker-1] ERROR com.intuit.karate - evaluation of 'karate-config.js' failed: javascript function call failed: unexpected 'configure' key: 'followRedirectss'
16:49:28.761 [ForkJoinPool-1-worker-1] ERROR com.intuit.karate - javascript function call failed: unexpected 'configure' key: 'followRedirectss'
16:49:28.762 [ForkJoinPool-1-worker-1] ERROR com.intuit.karate - failed function body: function fn(){   
   << MY SUPER AMAZING SCRIPT HERE >>
}

Note here I made if fail on purpose with trivial error just to provoke it ^

After the error it would print it for every scenario in every feature file I have, so having 55 feature files with 304 scenarios and karate-config.js with 104 lines you can imagine that this gets bad very fast.

So karate-config 5 lines long with intentional fail + 2 features with single scenario look something like this:

Any way to avoid this and to have fail on karate-config.js cause run to stop all together?

回答1:

As you know karate-config.js is executed before every scenario. A problem with this is considered "catastrophic". Karate is designed to try and move on to the next scenario.

Feel free to open a feature request and even contribute a fix - but my guess is because of the concept of a callSingle() it would be difficult to have the logic in place to do what you are requesting.

My personal opinion is that this behavior is acceptable, if karate-config.js fails - you have to fix it rather quickly. You can always use the JUnit runner or IDE integration to work on one feature and resolve this before moving on to the whole suite.
