What are the techniques used in manual testing?

Manual testing means testing an application with an actual keyboard or mouse. You can test the entire application or only a specific function with manual testing. Manual testing has the disadvantage that you can't see the result of your work immediately and that there is a possibility of human error. However, manual testing has a good side: manual testing is cost-effective. Manual testing is also called _white box testing_, " which means you test the application as if you were programming it. That is, you can test the application as an initial requirement specification.

What is a manual testing life cycle?

The manual test life cycle is a well-accepted model of a software testing process. This model, developed over the years, includes steps such as preparation, execution, recording, review, and correction.

Which testing is performed first?

The manual testers start with the user interface (UI). First, they check that the keys are clearly labeled and all the buttons are clearly labeled. If the UI has pull-down menus, the testers make sure that the menus are clear and can be easily understood. The number of items should be indicated. 

Next, the testers go through the reports, orders, and billing forms and make sure that all the fields are displayed correctly and can be read easily. They check that all the fields can be properly filled and that the fields are arranged logically. The testers also confirm that the colors, layouts, and font types used in the reports, orders, and billing forms are visible and easy to read. Hire manual testers to review the existing error messages and ensure they can be easily understood.

What is the difference between manual and automated testing?

Manual testing refers to the techniques used by testers (e.g., exploratory testing, white-box testing, black-box testing, exploratory testing). Automated testing refers to the application of automated testing tools such as PHPUnit, Selenium, etc. Manual, automated testing refers to integrating automated tools with manual testing techniques.
