Missing colons are not reported as invalid syntax

[thigg]

Describe the bug
If the colon after a scenario is missing, the scenario is simply not run, instead of being reported as invalid
To Reproduce
Steps to reproduce the behavior:

1. Create the following feature:

Feature: I am buggy

  Scenario: I put the colon in the end:
    Then I run the test

2. Run the feature

Expected behavior
The scenario is reported as invalid
Context & Motivation

It costs a lot of time if this happens, because the misplaced colon is not obvious

Your Environment
Cucumber 6.8.1

Fair enough.

For now I would recommend using an IDE with syntax highlighting. It should make it more apparent what the problem is:

Feature: I am buggy

  This a general description of the feature to explain what it does and put the scenarios in to context.
  It can be multiple lines long.

This will take a lot of effort to fix, and I don’t think it’s worth the effort. Thoughts?

[mpkorstanje]

I'm not sure. With the way the grammar is defined the Scenario keyword line terminates the description. The Step keyword line could be used in the same way and then used to detect this problem.

Thats why I opened a second issue at intellij ;)

Intellij was perfectly fine with the colon free version...
