Karate-Netty: Variables defined in calling feature are not present in the called features.

karate-sample-persistent-state-dynamic-scope.zip

Hello! I don’t know if is intended or not, but the dynamic scope in MockServer features doesn’t work, the test fails in the last line of the second proxy.feature Scenario.

proxy.feature

    * def outer_scope_variable = "hello"
    * call common_outer_scope  ERROR: org.graalvm.polyglot.PolyglotException: ReferenceError: "outer_scope_variable" is not defined

The call to common_outer_scope fails because it can’t find the outer_scope_variable defined anywhere. Also the built-in objects, like request\response are not accessible. This is only for karate-netty, in client features everything works as expected:

first-case.feature:

  * def outer_scope_variable = "hello"

  # Here the feature just logs the value of the `outer_scope_variable`, to demostrate
  # that the problem is only in karate-netty feature files
  * call common

I found another bug while investigating this, as you can see in proxy.feature, to the first call to common_request is specified an argument.

Scenario: pathMatches('resource')

    * match request == body_req

    * call common_request ({ test: 1, default_argument: "not default anymore" })
    ...

In the second call btw, (the second Scenario), the argument is not passed, but the called feature continues to see the old value.

Scenario: pathMatches('resource/bad')
    
    * match request == body_req_2

    * call common_request ({ test: 10 })

common-request.feature

    * def default_argument = karate.get('default_argument', "default value")
    * karate.log("Default Argument: ", default_argument)

EveryTimes it prints:

Default Argument: 'not default anymore'

This can endanger behaviours of feature files which relies upon defaults, making them not trustworthy.

hi, I had a look yesterday and this project is overly complex

the problem seems to be, on a server side feature, when calling another scenario with no arguments, the called scenario can not see the global variables from calling scenario

Attached is a minimun project that shows this error… karate-mocks-server-calling-other-scenario-error.zip
