Good Tests Flashcards
What four aspects of a program can be tested?
- Functional
- Operational
- Structural
- Usability
What is the functional aspect of a program?
Requested features working?
Input → expected output
- What is the operational aspect of a program?
2. How do you test it?
- Speed (memory/cpu usage)
2. Run program and check computer ressources
- What ist the structural aspect of a program?
2. How do you test it?
- Quality of the code
2. Manual review with best practices
What are the three measurements of Usability?
- Task performance
- Questionnaires
- Behaviour and physiology
What are the three (four) levels of functional testing?
- Unit
- Integration
- System
(4. Acceptance)
What are the principles for functional testing?
- Incremental
- Iterative
- Continous
What is incremental testing?
From function to system
What ist iterative testing?
Always test after modification
What is continuous testing?
Automatic build and testing on every push = iterative testing
What is a unit test?
Code testing the public behaviour of a class
What are the four Phases (As) of unit testing?
- Arrange (Setup)
- Act (Execute)
- Assert (Verify)
- Annihilate (Teardown)
What is test data?
Expected test results
What is a test case?
Set of input values, preconditions, expected results and postconditions
What is test fixture?
A fixed state of fake objects for running tests
