Automation & Manual Testing

Automation & Manual Testing

Software testing, essentially comprises of 2 methods –Manual & Automated. There are distinct differences between the testing types. To eradicated human effort is where automation came into existence! Automation Testing is the process of using tools, scripts, and software to perform test cases by repeating pre-defined actions. Test Automation focuses on replacing manual human activity with systems or devices. Because automated testing is done through an automation tool, it consumes less time in exploratory tests and more time in maintaining test scripts while increasing overall test coverage. The benefit of manual testing is that it allows a human mind to draw insights from a test that might otherwise be missed by an automated testing program. Automated testing is most preferable for large projects that require testing the same areas over and over.

The test automation performs testing at three different levels:

Unit Level Automation

API Testing

User Interface

Some of the reasons why Automation Testing is important:

Running Tests 24/7: You can start the test from anywhere in the world and anytime you want to. You can even do that remotely if you don’t have a lot of devices or you don’t have the possibility to buy them.

Fewer Human Resources: You just need a test automation engineer to write your scripts to automate your tests, instead of a lot of people doing boring manual tests over and over again.

Reusability: The scripts are reusable and you don’t need new scripts every time. Also, you can redo the steps that are exactly as the previous ones.

Bugs: Automation helps you find bugs in the early stages of software development, reducing expenses and working hours to fix these problems as well.

Reliability: Automated testing is more reliable and way quicker when running boring repetitive standardized tests which cannot be skipped, but may cause errors when manually tested.

Manual Testing is one of the most fundamental testing processes as it can find both visible and hidden defects of the software. The difference between expected output and output, given by the software, is defined as a defect. The developer fixed the defects and handed it to the tester for retesting.


Manual testing is mandatory for every newly developed software before automated testing. This testing requires great efforts and time, but it gives the surety of bug-free software. Manual Testing requires knowledge of manual testing techniques but not of any automated testing tool.


Whenever an application comes into the market, and it is unstable or having a bug or issues or creating a problem while end-users are using it.

If we don't want to face these kinds of problems, we need to perform one round of testing to make the application bug free and stable and deliver a quality product to the client, because if the application is bug free, the end-user will use the application more conveniently. If the test engineer does manual testing, he/she can test the application as an end-user perspective and get more familiar with the product, which helps them to write the correct test cases of the application and give the quick feedback of the application.


Types of Manual Testing

There are various methods used for manual testing. Each technique is used according to its testing criteria. Types of manual testing are given below:

White Box Testing

Black Box Testing

Gray Box Testing
