When to Perform Manual Testing?
Manual testing is done when automation can’t be used or isn’t enough. Here are key reasons and scenarios:
- Exploratory Testing: Discovering issues in new or unclear features by exploring them.
- Usability Testing: Checking if the UI is easy to use and looks good.
- Ad-Hoc Testing: Doing quick, informal tests after updates or bug fixes.
- Visual/GUI Testing: Checking the layout, colors, or how the site looks across different browsers.
Manual testing should be conducted when:
- Flexibility is required: With manual tests, QA can quickly test and provide fast feedback.
- Short-term projects: It is not advisable to invest more money and effort to set up short-term projects that focus on minor features because such setup will require huge effort and money that would be too high for such small projects.
- When testing end-user usability: Humans can use their sensibilities to understand the application behavior if the application offers a satisfactory user journey. No machine can perform this task as humans can.

When to Perform Automation Testing?
- When need to run repetitive tasks: Automated tests are the best option in scenarios where there is a requirement to run repetitive tests. For example, in the case of regression tests must be executed periodically to make sure that the newly added code does not disrupt the existing functionality of the software.
- When human resources are scarce: Automated tests are viable and the best option to get tests executed within deadlines when there are only a limited number of dedicated testers.
