The source code has 10 packages: correct, mutant1, mutant 2, …, and mutant 9. TriangleSides.java in the “correct” package is the original correct version. The reportTriangleType method in TriangleSides.java reports the type (EQUILATERAL, SCALENE, ISOSCELES and NOTRIANGLE) of a triangle, given the lengths of three integer sides a, b, and c. TriangleSides.java in each mutantX (X=1, …, 9) package is a mutant of the original version, where the reportTriangleType method is modified. The modifications are summarized below. mutantX Original Mutated version 1 if (a<b+c && b<a+c && c<b+a){ if (b<a+c && c<b+a){ 2 if (a==b && b==c) if (b==c) 3 if (a==b || b==c || c==a) if (a==b || c==a) 4 return TriangleType. SCALENE; return TriangleType.ISOSCELES; 5 if (a<b+c && b<a+c && c<b+a){} else return TriangleType.NOTRIANGLE; if-else removed 6 if (a==b || b==c || c==a) if (a==b || b<=c || c==a) 7 if (a<b+c && b<a+c && c<b+a){ if (a<b+c && b<=a+c && c<b+a){ 8 if (a<=0 || b<=0 || c<=0) if (a<=0 && b<=0 && c<=0) 9 if (a<=0 || b<=0 || c<=0) return TriangleType.NOTRIANGLE; // if (a<=0 || b<=0 || c0 AND b>0 AND c>0) On failure: return “NOTRIANGLE” (2) Validated: (a+b>c AND a+c>b AND b+c>a) On failure: return “NOTRIANGLE” Postconditions (3) IF (a=b AND b=c) THEN return “EQUILATERAL” (4) IF ((a=b AND b¹c) OR (a=c AND b¹c) OR (b=c AND b¹a)) THEN return “ISOSCELES” (5) IF (a¹b AND b¹c AND a¹c) THEN return “SCALENE” a b c a=b b=c a=c a+b>c b+c>a a+c >b Non-errorrequirements Errorrequirements Test Case ID Test input Expected result Test requirements in (2.1) satisfied by the test a b c Non-error requirements Error requirements 1 2 … Provide the source code of your TriangleSpecficationTest.java and a screenshot of your test execution result.
