ONE-CLICK RETEST
Pattern summary
Retesting a specific test case should be as easy as one mouse click
Category
Execution
Context
This pattern helps to efficiently retest previously failed tests.
This works if the system is state-less, i.e. you don't get different results depending on the state of something.
Description
Make the retest of a specific test case as easy as possible. If you have a TEST AUTOMATION FRAMEWORK to support you, you should be able to select the test case and run it literally with one mouse click
Implementation
If you can PRIORITIZE TESTS, it will be relatively easy to change the priorities to select only the desired test case. If you add another level of prioritization, you can reduce this effort even more (see Example 1)
Recommendations
An extra level of prioritization allows you to use this pattern even if you have INTERDEPENDENT TEST CASES (see Example 2)

Experiences
Here two examples from Seretta:
Example 1:
We have written some quite long test suites and even if we do have prioritisation in place (we distinguish between High, Medium, Low and Irrelevant), it took time to change the priorities so that only the one test case could be run for retest.
One of our typical test suites has a structure like this:
Business Process: My Test suite
Business Case: Business Case 1
Test Case: Test Case 1.1
- Test Procedure: Test procedure 1.1.1
- Test Procedure: Test procedure 1.1.2
- Test Procedure: Test procedure 1.1.3
- Test Procedure: Test procedure 1.1.4
- Test Procedure: Test procedure 1.1.5
- Test Procedure: Test procedure 1.1.6
Test Case: Test Case 1.2
- Test Procedure: Test procedure 1.2.1
- Test Procedure: Test procedure 1.2.2
- Test Procedure: Test procedure 1.2.3
- Test Procedure: Test procedure 1.2.4
- Test Procedure: Test procedure 1.2.5
- Test Procedure: Test procedure 1.2.6

Business Case: Business Case 2
Test Case: Test Case 2.1
- Test Procedure: Test procedure 2.1.1
- Test Procedure: Test procedure 2.1.2
- Test Procedure: Test procedure 2.1.3
- Test Procedure: Test procedure 2.1.4
- Test Procedure: Test procedure 2.1.5
- Test Procedure: Test procedure 2.1.6
Test Case: Test Case 2.2
- Test Procedure: Test procedure 2.2.1
- Test Procedure: Test procedure 2.2.2
- Test Procedure: Test procedure 2.2.3
- Test Procedure: Test procedure 2.2.4
- Test Procedure: Test procedure 2.2.5
- Test Procedure: Test procedure 2.2.6

Business Process and Business Case are just containers that allow us to categorize correctly the test cases. The test cases are composed of test procedures that call the actual test scripts.
The objects are colour coded to represent the priority. In this example all test procedures have priority High.
If we wanted to execute only Test Case 2.1 we would have to set the priority of all the other test cases to Medium, then execute the test case and finally not forget to reset the priorities for the next complete test run. It works, but it takes time and it’s error prone.
To solve this problem we introduced a second layer of prioritisation, which we called “To be executed”. We can choose from:
- On request
- With parent object
- Always
- Never
Now you can set this parameter to "On Request" for all objects, with the exception of test procedures. Test procedures are set to "With parent object". To select Test case 2.1 for execution we now only have to select the test case and click on the execution menu "To be executed". We don’t need to change any priority!

Example 2:
Lets take our test suite from above and lets imagine that any test case can can only be executed after Test case 1.1.
In this case we could set this parameter to "Always" for Test Case 1.1 and we leave the rest as defined in Example 1. Now when we execute Test Case 1.2 the system will always execute first Test Case 1.1!
