The following is the comment written for a C function

/* This function computes the roots of a quadratic equation a.x^2 + b.x + c = . The function stores two real roots in *root1 and *root2 and returns the status of validity of roots. It handles four different kinds of cases. (i) When coefficient a is zero irrespective of discriminant (ii) When discreminant is positive (iii) When discriminant is zero (iv) When discriminant is negative. Only in case (ii) and (iii) the stored roots are valid. Otherwise 0 is stored in roots. The function returns 0 when the roots are valid and -1 otherwise. The function also ensures root1 >= root2 int get_QuadRoots( float a, float b, float c, float *root1, float *root2); */

A software test engineer is assigned the job of doing black box testing. He comes up with the following test cases, many of which are redundant.

Which one of the following option provide the set of non-redundant tests using equivalence class partitioning approach from input perspective for black box testing?

Consider the method mcq ( ):
int mcq(boolean a, boolean b, boolean c, boolean d)
{
   int ans=1;
   if(a) { ans = 2; }
   else if (b) { ans = 3; }
   else if (c) {
                      if (d) { ans = 4; }
   return ans;
}
if
M1 = Number of tests to exhaustively test mcq( );
M2 = Minimum number of tests to achieve full statement coverage for mcq( ); and
M3 = Minimum number of tests to achieve full branch coverage for mcq( );
then (M1, M2, M3) = __________.

Which of the following statements is/are FALSE with respect to software testing ?
S1 : White-box tests are based on specifications; better at telling whether program meets specification, better at finding errors of omission.
S2 : Black- box tests are based on code; better for finding crashes, out of bounds errors, file not closed errors.
S3 : Alpha testing is conducted at the developer’s site by a team of highly skilled testers for software that is developed as a product to be used by many customers.

What is the availability of the software with following reliability figures
Mean Time Between Failures (MTBF) is 20 days
Mean Time To Repair (MTTR) is 20 hours

Regression testing is primarily related to

Regression testing is primarily related to

Acceptance testing is done by

Beta testing is carried out by

The approach to software testing is to design test cases to

Match List I with List II

	List I		List II
A	Scenario testing	I	To verify the I/O behaviour of text object
B	Regression testing	II	user acceptance methodology
C	Component testing	III	No new bugs after changes in the program
D	Beta testing	IV	The documentation of a use case

Choose the correct answer from the options given below:

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Validity checks real need of system users
Reason R: Completeness checks system user defined requirements
In the light of the above statements, choose the correct answer from the options given below

For a function of two variables, boundary value analysis yields,

Fault base testing technique is

Alpha and Beta testing are forms of

Black Box Software Testing method focuses on the:
