Constructor Details

#initialize(test_to_sources, tests_to_categories: {}) ⇒ TestFileMappingData

Returns a new instance of TestFileMappingData.

    Test files mapped to all source files they cover

  • tests_to_categories (Hash<String, Array<String>>) (defaults to: {}) —

    Test files mapped to their feature categories

end

Instance Method Details

#as_db_table ⇒ Array<Hash<Symbol, String>>

Rows for shared.test_file_mappings, one per test-and-source pair.

Carries no group, stage or section on purpose. Those describe the category rather than the mapping and change whenever stages.yml is reorganised, so storing them on every mapping multiplies rows for no gain.

Readers resolve ownership from shared.category_owners through category. That table keeps every historical row, up to 57 for one category, so a plain join fans out; dedupe it with ORDER BY category, timestamp DESC LIMIT 1 BY category.

Examples:

Return value

[
  { test_file: "spec/models/user_spec.rb", source_file: "app/models/user.rb",
    category: "team_planning" },
  ...
]

Returns:

  • (Array<Hash<Symbol, String>>) —

    Mapping data formatted for database insertion
