Software Testing (Manual & Automation)

Automation Testing Vs. Manual Testing: What’s the Difference

Automation testing is a process of changing any manual test case into the test scripts by using automation testing tools, and scripting or programming language is called automation

What is Manual Testing?

Manual testing is testing of the software where tests are executed manually by a QA Analyst. It is performed to discover bugs in software under development.

In Manual testing, the tester checks all the essential features of the given application or software. In this process, the software testers execute the test cases and generate the test reports without the help of any automation software testing tools.

Less reliable testing method because it’s conducted by a human. Therefore, it is always prone to mistakes & errors.
The manual testing process can’t be recorded, so it is not possible to reuse the manual test.
In this testing method, certain tasks are difficult to perform manually which may require an additional time of the software testing phase.

It is a classical method of all testing types and helps find bugs in software systems. It is generally conducted by an experienced tester to accomplish the software testing process.

KEY DIFFERENCE

Manual Testing is done manually by QA analyst (Human) whereas Automation Testing is done with the use of script, code and automation tools (computer) by a tester.
Manual Testing process is not accurate because of the possibilities of human errors whereas the Automation process is reliable because it is code and script based.
Manual Testing is a time-consuming process whereas Automation Testing is very fast.
Manual Testing is possible without programming knowledge whereas Automation Testing is not possible without programming knowledge.
Manual Testing allows random Testing whereas Automation Testing doesn’t allow random Testing.

What is Automation Testing?

In Automated Software Testing, testers write code/test scripts to automate test execution. Testers use appropriate automation tools to develop the test scripts and validate the software. The goal is to complete test execution in a less amount of time.

Automated testing entirely relies on the pre-scripted test which runs automatically to compare actual result with the expected results. This helps the tester to determine whether or not an application performs as expected.

Automated testing allows you to execute repetitive task and regression test without the intervention of manual tester. Even though all processes are performed automatically, automation requires some manual effort to create initial testing scripts.
