Constructor Details

#initialize(test_record:, repository:, test_records:) ⇒ ChangesVerifier

Returns a new instance of ChangesVerifier.

Parameters:

  • test_record (Dragnet::TestRecord) —

    The TestRecord object to verify.

  • repository (Dragnet::Repository) —

    A Dragnet::Repository object linked to the repository where the verification should be executed.

  • test_records (Array<Hash>) —

    The hash of all the test records. This is used to determine if the changes in the repository are only in the Test Record Files, in which case the Test Records will still be considered valid.
