An Approach of Vulnerability Testing for Third-Party Component Based on Condition and Parameter Mutation

Table 7

The testing result of parameter mutation.

Method name	Value constraint	Relational constraint	Time for generating test cases	Number of all test cases	Number of test cases that find faults	detecting rate
JudgeTriangle(int a, int b, int c)	𝑎>0; 𝑏>0; 𝑐>0	𝑎+𝑏>𝑐; 𝑎+𝑐>𝑏; 𝑏+𝑐>𝑎	218 ms	663	339	51.13%
Add(int a, int b)	𝑎>−10; 𝑏>−10	𝑎≥𝑏	62 ms	60	15	25%
Query(String s)	—	—	422 ms	9	1	11.11%
GetCharacterCount(String s)	—	—	An infinite loop is caused by data overflow	9	1	11.11%
IsAcuteTriangle(int a, int b, int c)	𝑎>0; 𝑏>0; 𝑐>0	𝑎∗𝑎+𝑏∗𝑏==𝑐∗𝑐	63 ms	964	543	56.33%
CIsLargest(int a, int b, int c)	𝑎>0; 𝑏>0; 𝑐>0	𝑐≥𝑎 && 𝑐≥𝑏	157 ms	615	112	18.21%
IsQuotient(int a, int b, int c)	𝑏≠0; 𝑎≥0; 𝑐≥0	𝑐∗𝑏==𝑎	250 ms	981	327	33.33%
