Ruby / Cucumber错误：步骤定义必须始终具有proc或符号

Question

My automation test suite for an application is written using Ruby/Cucumber. When I try to run the tests using the cucumber command, and I receive the following error: Step definitions must always have a proc or symbol . I can't find any references to this error online except for the source code itself.

Full stack trace:

Step definitions must always have a proc or symbol (Cucumber::Glue::StepDefinition::MissingProc)

Answer 1

I searched through my step definition files and found an incomplete step definition with no block:

Given 'There is a user'

The block was removed while resolving merge conflicts, and completing the step definition solved the error:

Given 'There is a user' do 
    (do stuff)
end
