test plan

Testing a custom web application before deployment involves a systematic process to ensure its quality, functionality, and stability. This process includes different types of testing, such as unit testing, integration testing, system testing, and acceptance testing. Each type focuses on specific aspects of the application and helps identify any issues or bugs. Testing is done using various techniques and tools, including manual testing and automated testing. It is essential to create a test plan, define test cases, execute test scenarios, and document any discovered defects. Thorough testing helps mitigate risks, improves user experience, and ensures the application performs as expected.
