Manual Testing Interview Questions And Answers

Manual testing is a method of software testing where the tester manually executes test cases without any automation tools. The process involves carefully analyzing the functionality, design, and usability of a software application to identify bugs, defects, and errors. During a manual testing interview, candidates are typically asked a variety of questions to assess their understanding and experience in this field. These questions may cover topics such as testing techniques, bug tracking, test case creation, and defect management. Well-structured and comprehensive answers showcasing practical knowledge and problem-solving abilities can greatly increase the chances of success in a manual testing interview.

1 - What is the importance of manual testing?

Manual testing is a crucial phase in the software development life cycle. It helps in identifying defects and verifying whether the software meets the expected requirements. It also allows for the detection of any usability or user interface issues.

2) What are the different types of manual testing?

Some of the different types of manual testing include functional testing, regression testing, smoke testing, exploratory testing, user acceptance testing, and integration testing. Each type of testing focuses on a specific aspect of the software's functionality.

3) What is exploratory testing?

Exploratory testing is an informal and ad hoc testing technique that involves simultaneous learning, test design, and test execution. Testers explore the software without a specific test script or plan and provide rapid feedback on its usability, functionality, and user experience.

4) What are the main components of a test plan?

A test plan consists of the following components:

  Objective, scope, and strategy

  Features/functionality to be tested

  Test environment and tools required

  Test schedule and resources

  Risks and mitigation strategies

  Test cases and scenarios

  Entry and exit criteria

  Traceability matrix

5) What is a test case?

A test case is a document that specifies the steps to be executed and expected results for a particular test scenario. It helps in ensuring that all aspects of the software are thoroughly tested.

6) What is regression testing?

Regression testing is executed to validate that the recent code changes have not affected the existing functionality of the software. It is performed after a new feature has been added or a bug has been fixed.

7) What is a defect?

A defect is a deviation or flaw in the software that does not meet the expected requirements. It can also be referred to as a bug or an issue.

8) How is a defect classified?

A defect can be classified based on its severity and priority. Severity refers to the impact of the defect on the system, while priority indicates its urgency to be fixed.

9) What is a test report?

A test report is a document that provides a comprehensive summary of the testing activities, including the number of test cases executed, passed, and failed. It also includes details about defects found and their status.

10) What are the different levels of testing?

The different levels of testing include unit testing, integration testing, system testing, acceptance testing, and user testing. These levels are organized based on the progression of software development from individual components to the entire system.

11) What is a test environment?

A test environment is a setup of software and hardware where the testing is carried out. It should mimic the production environment to ensure accurate and reliable results.

12) What is the difference between verification and validation?

Verification verifies whether the software meets the specified requirements and follows the design. Validation evaluates whether the software meets the user's actual needs and expectations.

13) What is black box testing?

Black box testing is a technique where the tester has no knowledge of the internal structure or code of the software. It focuses on the software's inputs, outputs, and expected behavior without considering its internal workings.

14) What is white box testing?

White box testing is a technique where the tester has knowledge of the software's internal structure and code. It involves testing at the code level to ensure the internal logic and branches are functioning correctly.

15) What is a test oracle?

A test oracle is a mechanism or source that determines the expected output for a given set of inputs. It can be a manual review, documentation, or an automated tool.

16) What is a boundary value analysis?

Boundary value analysis is a testing technique that involves testing the software with values at or just outside the specified boundaries. This helps in identifying the maximum and minimum values that can be inputted in the system.

17) What is positive and negative testing?

Positive testing is executed to validate the software's expected behavior when correct and valid input is provided. Negative testing is executed to validate the software's response to incorrect, invalid, or unexpected input.

18) What is usability testing?

Usability testing is a type of manual testing that involves evaluating the ease of use, learnability, and user experience of the software. It provides insights into how users interact with the software and identifies any issues with its user interface.

19) What is the difference between smoke testing and sanity testing?

Smoke testing is a basic level of testing that ensures the critical features of the software are functioning correctly. Sanity testing is a more in depth level of testing that verifies the recent changes to the software have not caused any major issues.

20) What is the defect life cycle?

The defect life cycle is a series of steps that a defect goes through, from its discovery to its resolution. The steps include identification, reporting, triaging, fixing, retesting, and closure.
