Feature: Argument validation
In order to catch errors fast
As a user
I need to see warnings and errors when I pass incorrect arguments
Scenario: Passing zero arguments to a variadic command
Given a WP installation
When I try `wp plugin install`
Then the return code should be 1
Then STDOUT should contain:
"""
usage: wp plugin install
"""
Scenario: Validation for early commands
Given an empty directory
And WP files
When I try `wp core config`
Then the return code should be 1
And STDERR should contain:
"""
Parameter errors:
"""
And STDERR should contain:
"""
missing --dbname parameter
"""
When I try `wp core config --invalid --other-invalid`
Then the return code should be 1
And STDERR should contain:
"""
unknown --invalid parameter
"""
And STDERR should contain:
"""
unknown --other-invalid parameter
"""
When I try `wp core version invalid`
Then the return code should be 1
And STDERR should contain:
"""
Error: Too many positional arguments: invalid
"""
And STDOUT should be empty
