Top 5 Benefits of Website Automation Testing
Automation is a huge buzzword in software development. For a QA Engineer, you need to have automation on your resume if you want to land that high paying job. One of the things that you may be asked during an interview or even while working with your team is, “What are the benefits of automation testing?”.

I am going to cover my top five benefits of automation testing. If you are new to automation and want to learn how to do it from scratch, check out Website Automation Testing for Beginners with Protractor.
1. Save Time
A significant part of a QA Engineer’s time in a project is allocated to regression testing.
If you don’t know what regression testing is, just think of it as making sure that everything that worked before still works.
It is typical to have to perform regression testing every sprint cycle. This testing could take a couple minutes or several days if you were to manually run them. It all depends on what feature was added or changed and how many test cases would be affected by the change.
With automated tests, you will be able to have those tests run on their own.
Since you don’t have to run the tests manually, you now have more time to do something else.. like write more automated tests!
2. Reduced Cost
This one is pretty obvious after reading the previous bullet. Time is money! By savings working hours of the employees, you are going to save money.
3. Faster Feedback
Imagine that you have all your test cases automated.
Now imagine that once the tests are complete you get a full report of:
- the tests that were run
- the tests the passed and failed
- screenshots of each failure
- bugs automatically created
Now imagine that this happens every time that code is deployed to the testing environment.
This immediate feedback allows you and your team to have confidence that the code deployed is in a good state.
Have you ever had to run a test case that you had written six months ago?
Do you remember what the requirements were? Do you know what data to use? Is what you are seeing 100% correct?
These questions are a prime example of why we need automated tests. You are not going to remember everything about every feature in the application.
Reusability circles back to “Saves Time”. Regression testing does not only take time to run the tests, but it takes time to relearn how the feature was supposed to work six months ago.
Imagine that you have written 100 Web Application test cases. Does that mean you will run 100 tests? NO!
The world of Web Applications is a complex and diverse world.
Let me show you what your user base is going to be for Web Applications. Your goal as a software team is to support all of these combinations at a bare minimum.
Browsers: 5 (Chrome, Safari, Edge, IE, Firefox)
Browser Versions: 2 each (We will limit to 2 each. Latest release and the previous major version.)
Operating Systems: 5 (Windows 10, Windows 7, iOS, OSX, Android)
Viewport Sizes: 5 (Full desktop, Tablet Landscape, Tablet Portrait, Phone Landscape, Phone Portrait)
Now take all of those combinations and multiply it by 100.
That is a lot of tests!
It is not realistic that your engineers are going to run every single test on every single combination. That would take too long and cost too much money.
However, if you automated the test you could have them run simultaneously on every single combination listed above.
Go Automate Stuff
