Software Testing and Quality Control Questions

Multiple choice

Which of the following is called regression testing?

  1. This testing ensures that the changes have no side effect on the rest of the applications after executing the same test that are previously conducted.

  2. This testing is used to test the failed cases again.

  3. This testing is used to test the software under some predefined constraints.

  4. This testing is used to test the software with extra data and inputs to check the efficiency of the software.

  5. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is true about regression testing.

Multiple choice

What are the following statements is/are not true?

  1. Regression is a planned testing.

  2. Regression testing is applied for the passed test cases.

  3. Retesting is a planned testing.

  4. Retesting is applied for the failed cases.

  5. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is a false statement as it is not a planned testing, while retesting is a planned testing.

Multiple choice

Which of the following is not a typical black-box test design techniques?

  1. All-pairs testing

  2. Equivalence partitioning

  3. Boundary value analysis

  4. Path testing

  5. Decision tables
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Basis path testing, or structured testing, is a method for designing test cases intended to examine each mathematically possible path of execution at least once.It is a white-box testing technique.

Multiple choice

Which of the following is not a type of control structure testing?

  1. Equivalence partitioning

  2. Branch testing

  3. Data flow testing

  4. Condition testing

  5. Loop testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Equivalence partitioning (also called Equivalence Class Partitioning or ECP) is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. It is a black-box testing technique. It is nota form of control-structural testing.

Multiple choice

Which of the following types of testing is usually done to determine if the system can sustain the continuous expected load?

  1. Stress testing

  2. Load testing

  3. Soak testing

  4. Spike testing

  5. Isolation testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Soak testing, also known as endurance testing, is usually done to determine if the system can sustain the continuous expected load. During soak tests, memory utilization is monitored to detect potential leaks. Also important, but often overlooked is performance degradation. That is, to ensure that the throughput and/or response times after some long period of sustained activity are as good or better than at the beginning of the test. It essentially involves applying a significant load to a system for an extended, significant period of time. The goal is to discover how the system behaves under sustained use.
