Manual testing involves human testers executing test cases, while automation testing uses automation tools to run test cases. Manual testing is time-consuming and relies on human resources, whereas automated testing is significantly faster. While manual testing requires investment in human resources, automation testing requires investment in testing tools and automation engineers who have programming knowledge.

1 In manual testing, test cases are executed by a
human tester and software.
Automation Testing uses automation tools to execute
test cases.
2 Manual testing is time-consuming and takes up
human resources.
Automated testing is significantly faster than a
manual approach.
3 Investment is needed for human resources. Investment is required for testing tools as well as
automation engineers.
4 No need for programming in Manual Testing. Programming knowledge is a must in automation
testing.
5 Manual Testing has a higher risk of missing out the
the pre-decided test deadline.
Automated Tests have zero risks of missing out a pre-
decided test.
6 Focus on human resources. Focus on automation.
7 Comparatively slower. Significantly faster.
8 Suitable for small to medium scale projects. Suitable for a complex and large project.
9 Can be repetitive and boring. Helps to avoid repetitive tasks as a QA "delegates"
them to a computer.
10 Investment is needed for human resources. Investment is required for testing tools as well as
automation engineers.
