Here are the few difference between manual vs automated testing
| Manual testing | Automated testing |
| Testers manual tests and find out defects | Here tools to run the tests are automated to find the defects. |
| Since done by humans, the errors are more. | Minimal error since it is done by tools. |
| Tests which require human validation this method is very useful | Here tools can only execute the automated tests. |
| It is time consuming | It runs in unattended mode and runs parallel in different platforms hence save time. |
| Low cost since it is done for short product life cycle | High cost of implementation and ROI in long term. |
| Higher errors are found due to monotonous work | High accuracy and quicker. |
