What Is Automation Testing? Why It’s Preferred Over Manual Testing.

What is automation testing? 
Automation testing refers to the process of using a software that executes a test case suite. This software or automation tool can also be used to generate results by entering test data into the system that is to be tested, then comparing or analyzing the given details. This type of testing is very different from manual testing, which needs a person to sit in front of their computer so they can manually execute the required steps for testing.

The Returns On Investment (ROI) of automated testing has greatly improved over time despite the fact that it costs more than manual testing. Once you execute the testing steps via automation, you will not need to manually perform any task which frees you to handle other rewarding tasks.

When you have your automated test in place, you can tweak and modify it so it can perform multiple tasks, something that cannot be achieved via manual testing. Due to this, automation testing has slowly curved a niche for itself as a crucial part of any development project.

Is automated testing better than manual testing? 
Here is a quick comparison of the two.
– Automation testing uses a software which would not get bored. The person who tests manually may sometimes get bored, which allows for errors. The automation tool on the other hand will perform the desired task with precision and execute everything to the last detail.
– Manual testing does not allow for testing of multilingual sites, something that is efficiently done via automation testing.
– An automated test can run for the longest time without human intervention. However, manual testing requires you to be present after set periods of time.
– Performing manual tests consumes a lot of time that could be invested towards other productive activities.
– Automation testing is fast and has a wider test coverage.

Which test cases are mostly automated?
An automated testing tool can be scheduled to replay actions that were previously recorded, compare results from manual tests, then provide an insight into anticipated actions to the test engineer. Here are some of the areas that are easily automated when testing.

1. The ones that are highly repetitive.
2. The ones that consume a lot of time if done manually.
3. Tedious tasks, the ones that cannot be manually performed.
4. High risk test cases.

Are there test cases that should not use automation testing? 
Yes, here is a list of some.
1. Very new test cases that have not yet been run through a manual testing procedure.
2. Test cases that are constantly updating their requirements.
3. Ad-hoc basis test files.

What happens when automation testing? 
The process can be explained in these simple terms. The first step is the test tool selection, then you will be required to define the scope of your automation procedure. Planning, design and development will be the next move right before you execute the test. The last step is maintenance which is routinely done to ensure that things are going according to plan.

Automated testing has provided a way to improve the coverage, efficiency and effectiveness of software testing. Remember, the goal of automated testing is not to completely erase manual testing but to simplify it and provide accuracy where humans may err.
