QA Automation

What are the drawbacks and pitfalls for not using automation testing in the project?

1- Manual testing takes a lot of time and effort, especially for repetitive tasks. This often results in longer testing cycles and delays in releases. ?

2- Since manual testing relies on human accuracy, it can sometimes be inconsistent and may miss critical defects. ?

3- Manual regression testing can be tedious and time-consuming, often leading to gaps in coverage of previous functionality, which can allow regressions to slip through. ??

4- Manual testing isn't suitable for performance, load, and stress testing because these require simulating many users and high-stress scenarios. ??

5- Automated tests can be reused across different projects and iterations, ensuring consistency and saving time. Manual tests don't offer this advantage, leading to repeated efforts.
