Recently in the review software worker here today to summarize the various white box tests covered ~
Order from high coverage to low coverage:
1.Path coverage
2.Combinatory coverage(multiple condition/combination coverage)
3. The Clause/ the Branch coverage
例 句 : The Clause is for coverage.
例 句 : The government has Branch coverage of the country.
6.Statement coverage
Here’s an example:
Path coverage – Path coverage
For path coverage, every combination of every path is traversed.
Here I have marked the abcDEF paths that may fork. For path coverage, I should go through the following paths:
acef
bcef
acdf
bcdf
Multiple condition coverage/combination coverage combinatory coverage
Every combination of clauses in every judgment is covered
X >3 and z<10
| x>3 | z<10 | x>3 and z<10 | |
|---|---|---|---|
| 1 | T | T | T |
| 2 | T | F | F |
| 3 | F | T | F |
| 4 | F | F | F |
X ==4 or y>5
| x==4 | y>5 | x==4 or y>5 | |
|---|---|---|---|
| 1 | T | T | T |
| 2 | T | F | F |
| 3 | F | T | F |
| 4 | F | F | F |
A set of test cases: (you will find that after inspection can meet all of the above 8) 1) {x = 4, y = 6, z = 5} 2) {x = 4, y = 3, z = 10} 3) {x = 3, y = 4, z = 5} 4) {x = 3, y = 6, z = 11}
Condition/judgment override
Clause coverage
The different true and false values of each clause in each judgment are taken once
X == 3 x==4 y == 3 x== 3 y == 3 x== 3 And so on and so forth
A set of test cases:
- {x=4, y=5, z=5}
- {x=3, y=6, z=15}
Judge to cover branch coverage
Marked on the graph, each judgment is followed by a result of T and F.
Judgment coverage is covered in test cases that can take at least one T and at least one F for each judgment.
A set of test cases:
- {x=4, y=5, z=5}
- {x=2, y=5, z=5}
