How can test execution tools be of most benefit during exploratory testing?
Answer(s): A
Exploratory testing is used when it is unclear what the system is supposed to do. Therefore test execution tools are of little use because expected results cannot be predicted. However, the record feature of a test execution tool can be used to log the actions performed so that defects can be recreated (option (A)) and rectified more easily.
Which of the following types of test tool are most likely to include traceability functions? (i) Performance testing tool(ii) Requirements management tool(iii) Configuration management tool(iv) Static analysis tool
Answer(s): C
Requirements management tools (ii) have traceability because they enable test conditions and subsequently test scripts and defects to be traced back to requirements. Configuration management tools (iii) also need to trace the appropriate version of a test script to the release or version of a system or module.Performance monitoring tools (i) and static analysis tools (iv) are designed for specific objectives. Neither of these tools particularly need traceability functions.
A system is designed to accept values of examination marks as follows:Fail: 039 inclusivePass: 4059 inclusiveMerit: 6079 inclusiveDistinction: 80100 inclusiveIn which of the following sets of values are all values in different equivalence partitions?
Answer(s): B
A washing machine has three temperature bands for different kinds of fabrics: fragile fabrics are washed at temperatures between 15 and 30 degrees Celsius; normal fabrics are washed at temperatures between 31 and 60 degrees Celsius; heavily soiled and tough fabrics are washed at temperatures between 61 and 100 degrees Celsius.Which of the following contains only values that are in different equivalence partitions?
Answer (A) includes two values from the lower partition, answer (B) contains two values from the second partition, answer (D) contains one value that is invalid (out of range).
Consider the following pseudo code:1 Begin2 Read Time3 If Time < 12 Then4 Print(Time, "am")5 Endif6 If Time > 12 Then7 Print(Time -12, "pm")8 Endif9 If Time = 12 Then10 Print (Time, "noon")11 Endif12 EndHow many test cases are needed to achieve 100 per cent decision coverage?
The three decisions are in sequence and the conditions are all mutually exclusive (if any one is true the others must be false). Hence a test case that makes the first decision true will make the second and third decisions false and so on.So test case 1 (say Time = 6) would exercise the path True, False, False, test case 2 (say Time = 15) would exercise the path False, True, False. Test case 3 would have to be Time = 12. This combination achieves 100 per cent decision coverage because each decision has been exercised through its true and its false outcomes.
