Consider the following state transition diagram of a two-speed hair dryer, which is operated by pressing its one button. The first press of the button turns it on to Speed 1, second press to Speed 2 and the third press turns it off. Which of the following series of state transitions below will provide 0-switch coverage?
- A.
A,C,B
- B.
B,C,A
- C.
A,B,C
- D.
C,B,A
Correct Answer
C. A,B,CExplanation
Evaluating the options:
In State transition testing a test is defined for each state transition.
The coverage that is achieved by this testing is called 0-switch or branch coverage.
0-switch coverage is to execute each loop once (No repetition. We should start with initial state and go till end state. It does not test ‘sequence of two state transitions’).
In this case the start state is ‘OFF’, and then press of the button turns it on to Speed 1 (i.e. A). Second press turns it on to Speed 2 (i.e. B) and the third press turns it off (i.e. C).
Here we do not test the combinations like what if the start state is ‘Speed 1’ or ‘Speed 2’ etc.
An alternate way of solving this is check for the options where it starts with ‘OFF’ state.
So we have options ‘a’ and ‘c’ to select from. As per the state diagram from ‘OFF’ state the dryer goes to ‘Speed 1’ and then to ‘Speed 2’. So our answer should start with ‘A’ and end with ‘C’.Rate this question:

Correct Answer
B. 2Explanation
Branch Coverage (BC):
To calculate Branch Coverage, find out the minimum number of paths which will ensure covering of all the edges. In this case there is no single path which will ensure coverage of all the edges at one go. By following paths 1A-2C-3D-E-4G-5H, maximum numbers of edges (A, C, D, E, G and H) are covered but edges B and F are left. To covers these edges we can follow 1A-2B-E-4F. By the combining the above two paths we can ensure of traveling through all the paths. Hence Branch Coverage is 2. The aim is to cover all possible true/false decisions.Rate this question:

Using equivalence partitioning method how many test cases are required for testing valid and invalid inputs for an input box accepting numbers from 1 to 1000?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
C. 3Explanation
Test cases for input box accepting numbers between 1 and 1000 using Equivalence Partitioning:
1) One input data class with all valid inputs. Pick a single value from range 1 to 1000 as a valid test case. If you select other values between 1 and 1000 then result is going to be same. So one test case for valid input data should be sufficient.
2) Input data class with all values below lower limit. I.e. any value below 1, as a invalid input data test case.
3) Input data with any value greater than 1000 to represent third invalid input class.
So using equivalence partitioning you have categorized all possible test cases into three classes. Test cases with other values from any class should give you the same result.
We have selected one representative from every input class to design our test cases. Test case values are selected in such a way that largest number of attributes of equivalence class can be exercised.
Equivalence partitioning uses fewest test cases to cover maximum requirements.Rate this question:

A junior tester with equivalence partitioning and BVA experience
- B.
A tester capable of preparing a test case for automation
- C.
An automation specialist capable of making it into a regression script
- D.
The most senior tester because this is a complex scenario
Correct Answer
A. A junior tester with equivalence partitioning and BVA experienceExplanation
The test lead should assign this test to a junior tester with equivalence partitioning and Boundary Value Analysis (BVA) experience because this test involves checking different ranges of percentages and their corresponding grades. Equivalence partitioning is a technique used to divide the input data into different equivalence classes, and BVA is used to test the boundaries of these classes. A junior tester with experience in these techniques would be able to effectively design and execute test cases for this scenario.Rate this question:

The V-Model test levels are:
- A.
Component (unit) testing, integration testing, system testing, acceptance testing
- B.
Component (unit) testing, acceptance testing, integration testing, system testing
- C.
Component (unit) testing, system testing, integration testing, acceptance testing
- D.
Component (unit) testing, integration testing, acceptance testing, system testing
Correct Answer
A. Component (unit) testing, integration testing, system testing, acceptance testingExplanation
The V-Model test levels are arranged in a sequential manner, starting with component (unit) testing, followed by integration testing, system testing, and finally acceptance testing. This order allows for a systematic approach to testing, where each level builds upon the previous one. Component testing involves testing individual components or units of the software, integration testing focuses on testing the interaction between these components, system testing verifies the entire system's functionality, and acceptance testing ensures that the system meets the user's requirements. Therefore, the correct order of the V-Model test levels is component (unit) testing, integration testing, system testing, and acceptance testing.Rate this question:

- D.
100% Path coverage
Correct Answer
D. 100% Path coverageExplanation
100% Path coverage offers the best coverage because it ensures that every possible path through the code has been tested. This means that all possible combinations of statements and branches are executed, resulting in a more thorough testing of the code. Decision coverage, statement coverage, and branch coverage may not cover all possible paths and therefore may not provide as comprehensive testing.Rate this question:

- B.
100% Statement coverage
- C.
100% Branch coverage
- D.
100% Path coverage
Correct Answer
B. 100% Statement coverageExplanation
100% Statement coverage offers the least coverage because it only ensures that every statement in the code has been executed at least once. It does not guarantee that all possible paths, branches, or decisions within the code have been tested. Therefore, there may be untested scenarios or potential bugs that could go unnoticed.Rate this question:
