Manual Testing Interview Questions and Answers
Question - 81 : - What is unit testing?
Answer - 81 : - Unit testing is the first level of testing and it involves testing individual modules of the software. It is usually performed by developers.
Question - 82 : - What are the different types of integration testing?
Answer - 82 : -
The different type of integration testing is-
- Big bang Integration Testing – In big bang integration testing, testing starts only after all the modules are integrated.
- Top-down Integration Testing – In top-down integration, testing/integration starts from top modules to lower-level modules.
- Bottom-up Integration Testing – In bottom-up integration, testing starts from lower-level modules to higher-level modules up in the hierarchy.
- Hybrid Integration Testing – Hybrid integration testing is the combination of both Top-down and bottom-up integration testing. In this approach, the integration starts from the middle layer and testing is carried out in both the direction
Question - 83 : - What is a stub?
Answer - 83 : - In the case of top-down integration testing, many times lower-level modules are not developed while beginning testing/integration with top-level modules. In those cases, Stubs or dummy modules are used that simulate the working of modules by providing a hard-coded or expected output based on the input values.
Question - 84 : - What is a driver?
Answer - 84 : -
In the case of bottom-up integration testing, drivers are used to simulating the working of top-level modules in order to test the related modules lower in the hierarchy.
Question - 85 : - What is system testing?
Answer - 85 : - System testing is the level of testing where the complete software is tested as a whole. The conformance of the application with its business requirements is checked in system testing.
Question - 86 : - What is acceptance testing?
Answer - 86 : - Acceptance testing is testing performed by the potential end-user or customers to check if the software conforms to the business requirements and can be accepted for use.
Question - 87 : - What is UAT Testing?
Answer - 87 : - UAT testing is the last phase of the testing lifecycle. Its main focus is to validate that software is working in accordance with business requirements.

Question - 90 : - What is beta testing?
Answer - 90 : - Beta testing is the testing done by end-users at the end user’s site. It allows users to provide direct input about the software to the development company.
