Lettuce is a BDD (Behavior Driven Development) testing tool for Python based on the excellent Cucumber project. It has most of the same features that Cucumber has, and has proven invaluable in my projects. I discovered an undocumented feature the other day called “Tags”. Cucumber has them, so I also assumed that Lettuce had them. Tags allow you to selectively skip or run scenarios. For instance:
Feature: Some Feature Scenario: This is scenario 1 Given I do stuff And I see stuff Then I am stuff @mytag Scenario: This is scenario 2 Given I do more stuff And I see more stuff Then I am more stuff
You can use tags in many ways.
lettuce --tag=mytag # Run only scenarios with this tag lettuce --tag=-mytag # Don't run scenarios with this tag ./manage.py harvest --tag=mytag # Django/Lettuce way of using tags.
