Top 10 Essential Software Testing Interview Question

Software Testing Interview Question

Are you searching for software testing interview questions?  The team at GoApti has prepared a list of 10 important questions you maybe quizzed on.

Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Software testing can also provide an objective, an independent view of the software to allow the business to appreciate and understand the risks of the software implementation.

Test techniques include the process of executing a program or application with the intent of finding software bugs (errors or other defects) and verifying that the software product is fit for use.

Software testing involves the execution of a software component or a system component to evaluate one or more properties of interest. In general, these properties indicate the extent to which the component or system under test:

  • Meets the requirements that guided its design and development,
  • Responds correctly to all kinds of inputs,
  • Performs its functions within an acceptable time,
  • Is sufficiently usable,
  • Can be installed and run in its intended environments.
  • Achieves the general result of its stakeholder’s desire.

1. What are quality assurance and quality control in software testing?

Quality assurance comes in process-oriented activities. It is used to ensure the prevention of defects in the process or methodology used to make software applications. Quality assurance prevents defects the whole application development is complete.

Quality control comes in product-oriented activities. It executes the script logic to identify the defects and the bugs in the software application.

2. What is the meaning of audit, inspection, and debugging in software testing?

  1. Audit − It is a well-planned systematic process to determine the testing process is conducted within an organization. it is independent of the processes involved during the testing of software in the company.  It is a review of documented processes which is used in the company. Types of the audit include Internal Audit, Legal Compliance Audit, and System Audit.
  2. Inspection – It is a formal evaluation technique in which software requirements codes; designs are examined in more detail by a person or a group other than the developer of software to detect defects, violations of development standards, or any other problems. It is a way to formal or informal review s of any developed artifact technically by identifying any defects or gaps.
  3. Debugging – It is processed to find out the root cause of the bug. It is performed by a software developer. IDE is used to perform the debugging where the developer run the software in debugging mode and go into code line by line to find out the exact root cause of the bug

Q3. Explain the white box testing how many types of white box testing and what are the steps of white box testing?

In White box test cases selected based on an analysis of the internal structure of the system and its subcomponents, it includes Code coverage, paths coverage, condition coverage branches coverage, etc.

  • Decision Coverage
  • Statement Coverage

   Steps of the white box testing are given below.

  1. Verify the flow of system’s and its components structure according to the document specification
  2. Verify broken paths in the code
  3. Verify the security holes in the code
  4. Verify the expected outputs
  5. Testing of the conditional loops in the code to ensure the complete working functionality of the software application.
  6. The software is tested line by line to ensure the 100% coverage of testing

Q4. Explain the black box testing? What is the different type of black-box testing that exists in software industries?

This is the most common Software testing question which is asked in an interview. The functionality of the software application is tested in black-box testing. Black box testing is the software testing methodology in which software is tested without knowing how It is implemented, how the code is flowing, how is the internal structure, what code has been written for a particular functionality. The different type of black-box testing techniques are given below

  1. Equivalence Partitioning
  2. Cause-effect graphing
  3. Boundary value analysis

Q5. Explain the differences between static and dynamic testing?

  1. Static testing: In static testing, code execution does not perform, it is done by testing documentation
  2. Dynamic testing:  In dynamic testing, a code is executed to perform the testing.

Q6. What are the tables in the test plans?

The test plan document contains the following things Scope, Test design, test strategies, and many other details.

  • Test strategy & Test approach
  • Test case identifier
  • Features to be tested
  • Test deliverables
  • Scope
  • Risk and Contingencies
  • Staffing and training
  • Features not to be tested
  • Responsibilities

Q7. What is the difference between System Testing and User Acceptance Testing?

  1. System Testing: In this type of testing, the software application undergoes from the start stage until the end. It is a way to find the defects when the system undergoes testing including all the components at the same time, that’s why it is known as an end to end testing.
  2. User Acceptance Testing: It involves running an application software by a sequence of specific test cases which determines whether the software will meet the needs of its users’ requirements.

Q8. Explain the difference between test cases, test scenarios, and test script?

  1. Test Cases:  it is a document of test cases to be executed it is created an earlier stage of software development.
  2. Test Scenarios:  Test scenarios are prepared in an earlier stage of the software testing; it includes many things like plans for the testing product, environmental condition, and several team members, making test plans, making test cases, and all the features that are to be tested for the application.
  3. Test Script:  It is written in programming language dependents on the requirement and in simple terms, it is a program which going to test part of the functionality of the software system or subsystem.

Q9. What is the testing type and what is the testing type?

To get the desired test result a standard procedure and steps are followed which is called Testing Type.

Commonly used testing types are

  1. Agile Testing: It is a way of testing by the Agile technique
  2. API Testing: Different testing APIs created for the application
  3. Unit Testing:  It is the testing of a small bock of the code of an application
  4. Install/ Uninstall Testing: Testing done from the point of end-users’  requirement
  5. Integration Testing: All the Individual  small modules are combined then tested
  6. System Testing: Is the whole testing of the system.

Q10. Explain the difference between the Traceability matrix and the Test matrix?

  1. Traceability Matrix: It is mapping between customer requirements and test cases.
  2. Test Matrix:  It is used to a grape effort, actual quality, resources the plan and time required to capture all phases of software application testing.
