Description

Create a Universal_Runtime_Preparation to handle all preparations required for when at least one Runtime_Check is being run.

This Preparation depends on the following issues and should be started once they are complete.

• Create Minimal_Theme_Preparation #56
• Create Force_Single_Plugin_Preparation #58

Acceptance Criteria

• Class Universal_Runtime_Preparation should be created and exists at includes/Checker/Preparations/Universal_Runtime_Preparation.php.
• Class Universal_Runtime_Preparation should extend Preparation interface.
• Class has a protected $check_context property.
• Class constructor accepts an instance of the Check_Context and assigns it to the $check_context property.
• Class contains a prepare() method that accepts no parameters and will do the following:
  • Instantiate the Use_Minimal_Theme_Preparation to use the wp-empty-theme in the Plugin Checker.
  • Instantiate the Force_Single_Plugin_Preparation to activate the plugin being checked.
  • Runs the prepare() method on the instances of both Use_Minimal_Theme_Preparation and Force_Single_Plugin_Preparation
  • Returns a cleanup function that loops over the cleanup functions returned by both the Use_Minimal_Theme_Preparation and Force_Single_Plugin_Preparation prepare methods.

Test Coverage

• Test the prepare method returns a callable cleanup function.
• Test that Use_Minimal_Theme_Preparation was successfully prepared by testing get_option( 'template' ) returns wp-empty-theme slug.
• Test that Force_Single_Plugin_Preparation was successfully prepared by testing get_option( 'active_plugins' ) returns the plugins basename.
