|
Definition
| Use equivalence partitioning by three criteria, coverage, disjointedness, representation |
|
|
Term
| In blackbox testing, what are two guidelines for selection of equivalence classes? |

Term
| What are 3 pros of blackbox testing? |
|
Definition
| testers can be non-technical, test cases can be designed early, identify vagueness of requirement |
|
|
Term
| What are 3 cons of blackbox testing? |
|
Definition
| might be too many inputs, chance of having non-covered case, difficult to apply tricky inputs |
|
|
Term
| What does whitebox testing focus? |
|
Definition
| coverage of different cases |
|
|
Term
| What are four types of white-box testing? |
|
Definition
| statement testing, loop testing, path testing, branch testing |
|

|
Term
| Compare blackbox and whitebox testing, giving 3 points for each |
|
Definition
Whitebox: potentially infinite number of path needs to be tested, tests what is done instead of what should be done, cannot detect missing use cases
Blackbox: potential combinatorial explosion of test cases, not clear if a test case will uncover particular error, fails to discover side effects |
|
|
Term
| Why both blackbox and whitebox testing are needed? |
|
Definition
| Because they are at the extreme ends of testing space |

Term
| What are 8 steps of unit testing heuristics? |
|
Definition
1. Create unit tests when object design is completed
2. Develop the test cases
3. Cross-check the test cases
4. Desk-check source code
5. Create a test harness
6. Describe the test oracle
7. Execute the test cases
8. Compare the results of the test with the test oracle |

| Describe 5 stages of Test-Driven Development Cycle |
|
Definition
1. Add a new test to the test model
2. run the automated tests
3. write code to deal with the failure
4. run the automated tests
5. refactor code |
