Software testing is used to test the application and see weather features are working fine or not and the process of finding defects and ensure the app is working fine.
Software testing is the most important process to ensure the product is working according to the given standards.
In software testing we have different types of testing they are unit testing system testing regression testing smoke testing integration testing performance testing UAT testing.
Testing techniques are black box testing , white box testing, grey box testing white box testing is done by SDE and black box testing is done by QA and grey box testing is done by SDET
The relevance of software testing is to ensure that the product quality is up to the standards
Software testing is the process of evaluating and verifying that a software product or application performs as expected. It aims to identify defects, validate functionality, and ensure that the software meets user requirements. Here are some key points about software testing:
Importance of Testing:
Preventing Bugs: Effective testing helps prevent defects and bugs from reaching end-users, improving overall software quality.
Performance Enhancement: Testing identifies bottlenecks, performance issues, and areas for optimization.
Risk Mitigation: Testing reduces the risk of software failure, security vulnerabilities, and data loss.
Types of Software Testing:
Unit Testing: Validates individual software units (e.g., functions, methods) to ensure they work correctly.
Integration Testing: Verifies that different components or modules of the software interact seamlessly.
Functional Testing: Tests specific functions based on business scenarios and requirements.
Regression Testing: Ensures that new features or changes do not break existing functionality.
Performance Testing: Evaluates how the software performs under different workloads.
Security Testing: Validates that the software is secure and not vulnerable to attacks.
Usability Testing: Assesses how well users can interact with the system.
Testing Techniques:
Black-Box Testing: Focuses on external behavior without knowledge of internal code. Testers create scenarios based on requirements.
White-Box Testing: Examines internal code logic, ensuring all paths are tested. Typically done by developers (SDEs).
Grey-Box Testing: Combines elements of both black-box and white-box testing. Often performed by SDETs.
Continuous Testing:
Testing should start early in the development process and continue throughout the software lifecycle.
