Manual testing is the most basic form of testing in which a tester runs tests on software, comparing the expectations to the actual outcomes in order to find software errors. This is a classic type of testing that has been incorporated in tech companies for years and is usually the best option for smaller projects.
Manual testing has it’s pros such as a lower short-term cost, a greater flexibility, and a less robotic testing process. However, in some cases manual testing may not be the best option for your project. There are a few cons and downfalls, especially when dealing with large projects. Depending on your project, the downfalls may outweigh the pros and you may realize there are better alternatives out there– such as automated testing. So why NOT to use manual testing?
Here is 3 Reasons Not to use Manual Testing:
Frequent code changes
Manual testing is usually not the preferred option when dealing with regression, load, or performance testing. Automated testing is seen as the more suitable option here because of the frequent changes in code, the thousands of users simulated to test performance, and the overall large quantity of material. If a task needs to be repeated for a certain number of times– let’s say 300– then the repeated execution would be tiring and take way too long if not done automatically.
If you are under a hard deadline and short on time, manual testing is probably not the best option. It is time consuming and will take more human resources than automatic testing. If faced with a quick deadline, the testers might not be able to test the software thoroughly and catch all of the errors. Automatic testing is more reliable since it is performed through tools and by scripts; it is also much faster.
Running tests simultaneously
One reason why you may not want to use manual testing is because you cannot reuse the manual tests. If you add anything to the test cases, you have to run the tests again by hand. This can be very annoying if you need to add multiple things. You do not have to set anything up again with automatic tests. Just add what you need to the program and rerun it instantly.
While there are both pros and cons to manual testing, it is really up to you to decide if this method will work. Use common sense and ask yourself if manual testing fits the specifications you need. Consider the size of the project and also consider the budget set aside for testing.
We hope that this reasons on not to use manual testing will help you make sense of things.
