Syntax-Based Testing in Software Incoporate PDF417 in Software Syntax-Based Testing




How to generate, print barcode using .NET, Java sdk library control with example project source code free download:
Syntax-Based Testing use software pdf 417 printing toinsert pdf 417 for software Microsoft's .NET Framework an execution of a subpath Software PDF-417 2d barcode from the deleted de nition of x to the output without an intervening de nition (def-clear). Since the output is considered a use, this satis es the criterion. Second, if x is not an output variable, then not de ning x at si must result in an incorrect output state.

This is possible only if x is used at some later point during execution without being rede ned. Thus, t satis es the all-defs criterion for the de nition of x at si , and the mutation operator yields all-defs, ensuring that mutation subsumes all-defs. It is possible to design a mutation operator speci cally to subsume all-uses, but such an operator has never been published or used in any tool.

. EXERCISES Section 5.2. 1. Provide reachability co Software PDF 417 nditions, infection conditions, propagation conditions, and test case values to kill mutants 2, 4, 5, and 6 in Figure 5.1.

2. Answer questions (a) through (d) for the mutant in the two methods, ndVal() and sum(). (a) If possible, nd a test input that does not reach the mutant.

(b) If possible, nd a test input that satis es reachability but not infection for the mutant. (c) If possible, nd a test input that satis es infection, but not propagation for the mutant. (d) If possible, nd a test input that kills mutant m.

3. Refer to the TestPat pr Software pdf417 ogram in 2. Consider Mutant A and Mutant B given below: (a) If possible, nd a test case that does not reach the mutant.

(b) If possible, nd a test input that satis es reachability but not infection for the mutant. (c) If possible, nd a test input that satis es infection, but not propagation for the mutant. (d) If possible, nd a test input that kills mutant m.

(a) while (isPat == false && isub + patternLen - 1 < subjectLen) while (isPat == false && isub + patternLen - 0 < subjectLen) // Mutant A (b) isPat = false; isPat = true; // Mutant B 4. Why does it make sense to remove ineffective test cases . Coverage Criteria 5. De ne 12 mutants for th pdf417 2d barcode for None e following method cal() using the effective mutation operators given previously. Try to use each mutation operator at least once.

Approximately how many mutants do you think there would be if all mutants for cal were created . public static int cal (int month1, int day1, int month2, int day2, int year) { //*********************************************************** // Calculate the number of Days between the two given days in // the same year. // preconditions : day1 and day2 must be in same year // 1 <= month1, month2 <= 12 // 1 <= day1, day2 <= 31 // month1 <= month2 // The range for year: 1 ..
