Defined in:

Overview

Used with ‘predictor.use Crystalball::Predictor::ModifiedSupportSpecs.new`. Will find files that match passed regexp and return full spec files which uses matched support spec files. Perfectly works for shared_context and shared_examples.

Instance Method Summary

• #call(diff, map) ⇒ Array<String>

  The spec paths associated with the changes.

• #initialize(support_spec_pattern = %r{spec/support/.*\.rb\z}) ⇒ ModifiedSupportSpecs constructor

  A new instance of ModifiedSupportSpecs.

Constructor Details

#initialize(support_spec_pattern = %r{spec/support/.*\.rb\z}) ⇒ ModifiedSupportSpecs

Returns a new instance of ModifiedSupportSpecs.

Parameters:

• support_spec_pattern (Regexp) (defaults to: %r{spec/support/.*\.rb\z}) —

  • regexp to filter support specs files

  @support_spec_pattern = support_spec_pattern
end

Instance Method Details

#call(diff, map) ⇒ Array<String>

Returns the spec paths associated with the changes.

Parameters:

• diff (Crystalball::SourceDiff) —

  • the diff from which to predict

  which specs should run

• map (Crystalball::ExampleGroupMap) —

  • the map with the relations of

  examples and used files

Returns:

• (Array<String>) —

  the spec paths associated with the changes
