Test coverage refers to the degree to which a software testing suite covers the functionality and requirements of the system under test. It measures the extent to which the test cases have executed and evaluated the code, and identifies any gaps in testing that may exist. Test coverage is important for ensuring that the software is reliable and functional, and that it meets the intended specifications and requirements.
Functional testing is a type of software testing that evaluates the functionality of a software application by testing its individual features or functions. It involves testing the software to ensure that it meets the requirements and specifications outlined in the project documentation. The main objective of functional testing is to verify that the software is performing as expected and meets the end-users' needs. This type of testing involves both manual and automated techniques and includes testing different scenarios, inputs, and outputs of the application to ensure that it is working correctly. Functional testing is an essential part of the software development lifecycle and helps to ensure that the software is reliable, efficient, and meets the user's expectations.
Non-functional testing is a type of software testing that evaluates the performance, usability, reliability, and other aspects of the system that are not related to its functionality. It includes testing the software to ensure that it meets non-functional requirements such as scalability, security, maintainability, and compatibility with different platforms and devices. Non-functional testing is important because it ensures that the software is not only functional but also reliable, efficient, and user-friendly. This type of testing involves both manual and automated techniques and includes testing different aspects such as response time, load testing, stress testing, and security testing. Non-functional testing is an important part of the software development lifecycle and helps to ensure that the software meets the end-users' expectations and performs well in various environments.
Test Phases
Test phases refer to the different stages involved in the software testing process. These phases typically include planning, preparation, execution, and reporting. During the planning phase, testers work with project stakeholders to determine the scope and objectives of the testing process, define test requirements, and develop a test plan. In the preparation phase, testers create test cases, develop test scripts, and set up test environments. The execution phase involves running the tests and identifying any defects or issues that arise. Finally, in the reporting phase, testers analyze the results of the testing process, report on any defects found, and provide recommendations for improvements or further testing. Test phases help ensure that the testing process is thorough, well-organized, and effective in identifying any issues or defects in the software.
