Quality Assurance (QA) plays an important role in making any software reliable, safe, and user-friendly. Every company wants to deliver a product that works smoothly and meets customer expectations. To achieve this, QA helps check the quality at every step of development. It is not only about finding bugs but also about improving the overall process so that mistakes can be prevented early. In simple words, Quality Assurance ensures that the software is built in the right way

Manual testing is the most important step in making any software reliable and user-friendly. It helps testers check an application step by step, just like a real user would. This process ensures that the software works correctly before it is released to the public. In manual testing, testers follow written instructions called test cases. These test cases guide them through different features of the software to check whether everything works as expected. If something is not wo

Learning how to test APIs is an important skill for anyone working in software development or testing. Postman is one of the most popular tools used for this purpose because it is easy to use and provides a clear interface for sending and checking API requests. Whether you are a student, tester, or developer, Postman helps you understand how different systems communicate with each other. Postman allows you to send different types of requests, such as GET, POST, PUT, and DELET

Software testing becomes easier when both technical and non-technical team members understand how the application should behave. This is where Cucumber helps. It is a popular tool used for Behavior Driven Development (BDD), which means it focuses on the behavior of the software from the user’s point of view. The main advantage of Cucumber is that it uses plain English to describe test scenarios, so anyone can read and understand them. In Cucumber, you describe how the system

Performance testing is an important part of software development to ensure that an application works smoothly under different loads. Apache JMeter is one of the most popular tools used for testing the performance and stability of web applications.
