Manual Testing is a process where testers evaluate software applications by executing test cases without the use of automation tools. This approach allows testers to interact with the application just like an end user would, identifying any bugs or issues that may affect the user experience. Testers rely on their intuition and experience to explore the software, ensuring it meets the specified requirements. In Manual Testing, the focus is on understanding the application's functionality and usability. Testers create detailed test plans and execute them step-by-step, documenting any discrepancies they find. This hands-on method is essential for catching issues that automated tests might overlook, making it a vital part of the software development lifecycle.
