Testing Interview Questions and Answers
Question - 111 : - What is random/monkey testing? When is it used?
Answer - 111 : -
Random testing is often known as monkey testing. In such type of testing data is generated randomly often using a tool or automated mechanism. With this randomly generated input, the system is tested, and results are analyzed accordingly. These testing are less reliable; hence it is normally used by the beginners and to see whether the system will hold up under adverse effects.
Question - 112 : - Which of the following are valid objectives for incident reports?
Answer - 112 : -
- Provide developers and other parties with feedback about the problem to enable identification, isolation, and correction as necessary.
- Provide ideas for test process improvement.
- Provide a vehicle for assessing tester competence.
- Provide testers with a means of tracking the quality of the system under test.
Question - 113 : - Consider the following techniques. Which are static and which are dynamic techniques?
Answer - 113 : -
- Equivalence Partitioning.
- Use Case Testing.
- Data Flow Analysis.
- Exploratory Testing.
- Decision Testing.
- Inspections.
Data Flow Analysis and Inspections are static; Equivalence Partitioning, Use Case Testing, Exploratory Testing and Decision Testing are dynamic.
Answer - 114 : -
Because they share the aim of identifying defects but differ in the types of defect they find.
Question - 115 : - What are the Structure-based (white-box) testing techniques?
Answer - 115 : -
Structure-based testing techniques (which are also dynamic rather than static) use the internal structure of the software to derive test cases. They are commonly called ‘white-box’ or ‘glass-box’ techniques (implying you can see into the system) since they require knowledge of how the software is implemented, that is, how it works. For example, a structural technique may be concerned with exercising loops in the software. Different test cases may be derived to exercise the loop once, twice, and many times. This may be done regardless of the functionality of the software.
Question - 116 : - When should “Regression Testing” be performed?
Answer - 116 : -
After the software has changed or when the environment has changed Regression testing should be performed.
Question - 117 : - What is negative and positive testing?
Answer - 117 : -
A negative test is when you put in an invalid input and receives errors. While positive testing is when you put in a valid input and expect some action to be completed in accordance with the specification.
Question - 118 : - What is the purpose of a test completion criterion?
Answer - 118 : -
The purpose of test completion criterion is to determine when to stop testing
Question - 119 : - What are the Experience-based testing techniques?
Answer - 119 : -
In experience-based techniques, people’s knowledge, skills, and background are a prime contributor to the test conditions and test cases. The experience of both technical and business people is important, as they bring different perspectives to the test analysis and design process. Due to previous experience with similar systems, they may have insights into what could go wrong, which is very useful for testing.
