The correct sequence of tasks for refactoring test cases is:
* Identification: Recognize the need and potential areas for refactoring.
* Analysis: Assess the impact and dependencies related to the changes.
* Refactor: Make the actual modifications to improve the test cases.
* Re-run: Execute the modified test cases to ensure they still meet the required objectives.
* Evaluate: Assess the outcomes of the refactor to ensure effectiveness and efficiency.
This sequence is supported by the ISTQB documentation, emphasizing the methodical approach needed to efficiently update and improve test cases, ensuring they remain effective and relevant .
