undefined method `keys' for #<Cucumber::Messages::GherkinDocument::Feature:0x0801ea30> (NoMethodErr or)

Facing problem when try to run 'parallel_tests' in Cucumber + Ruby framework. Command which I use:

bundle exec parallel_cucumber -n 3 features/someFeature --group-by scenarios

Error I get:

undefined method `keys' for #<Cucumber::Messages::GherkinDocument::Feature:0x07fba0b0> (NoMethodErr

Thing I want is to run different scenarios in different processes to minimize tests running time.

  • Cucumber version 3.2.1
  • Ruby version 2.6.0
  • parallel_tests 3.0
  • cuke_modeler 3.1.0
  • cucumber-gherkin 14.0.1

Update After updating cucumber to 4.1 I get another error

Solution

  • I've solved the problem. Seems that something went wrong with dependencies and versions. Combination of:

    • cucumber (3.1.2)
    • parallel_tests (2.32.0)
    • NO cuke_modeler AT ALL

    works fine for me!
