Feature: Randomize
Use the `--order random` switch to run scenarios in random order.
This is especially helpful for detecting situations where you have state
leaking between scenarios, which can cause flickering or fragile tests.
If you do find a randmon run that exposes dependencies between your tests,
you can reproduce that run by using the seed that's printed at the end of
the test run.
Background:
Given a file named "features/bad_practice.feature" with:
"""
Feature: Bad practice
Scenario: Set state
Given I set some state
Scenario: Depend on state
When I depend on the state
"""
And a file named "features/step_definitions/steps.rb" with:
"""
Given(/^I set some state$/) do
$global_state = "set"
end
Given(/^I depend on the state$/) do
raise "I expect the state to be set!" unless $global_state == "set"
end
"""
Scenario: Run scenarios in order
When I run `cucumber`
Then it should pass
@spawn
Scenario: Run scenarios randomized
When I run `cucumber --order random:41515`
Then it should fail
And the stdout should contain:
"""
Randomized with seed 41515
