Differences: Manual VS Automation Testing - Which One Should You Use?

by Diya S. Digital Marketer

What is Manual Testing?


Manual testing is the testing of software where the tests are performed manually by done by a software tester. It is done to find out bugs in the software under-development.


With manual testing, the software tester checks all the important features of the provided software or application. During this procedure, software testers perform test cases to produce test reports without the help of automated software testing tools.



What is Automation Testing?


In Automation Testing, the software testers write codes or test scripts for automating test performance. Testers use suitable automation tools for developing the test scripts as well as validate the software. The objective is to complete the test executions in less time.


Automation Testing completely depends on the pre-scripted tests that run automatically to associate actual results with the anticipated results. It helps the software tester to define whether or not the application works as expected.



What’s the Difference?


Software testing is an enormous domain however, this can be largely characterized into two different areas named manual testing and automation testing.


Both manuals as well as automation testing offer advantages as well as disadvantages. So, it’s important to understand the difference as well as where to utilize one or another to get the finest results.


In manual testing, the test cases are implemented manually by a human without using any scripts or tools. However, in automation testing, the test cases are implemented with the help of scripts, tools, and software.



Manual vs. Automation Testing: Pros & Cons


Both Manual testing, as well as automation testing, comprise two huge areas. Within every category, particular testing techniques are accessible like a white box testing, black-box testing, load testing, system testing, integration testing, and performance testing. Let’s go through a brief evaluation along with their pros & cons:




  • Manual testing can’t be so accurate because of human errors, therefore, it is lesser reliable.
  • Automation testing is more dependable because it is done by scripts or tools.


  • Manual testing takes more time because of human resources.
  • Automation testing is performed by software, therefore it is considerably quicker than the manual approach.


  • Manual testing is practical only when the tests are run 1-2 times and frequent recurrence is not needed.
  • Automation testing is a more practical choice when the tests are run frequently over a longer time.

Human Observation

  • Manual testing allows human observation that might be more helpful if the objective is accessibility and better customer experience.
  • Automation testing does not involve human observation so it cannot promise accessibility and progressive customer experiences.



Manual Testing Should Be Preferred For the Following Scenarios:

  • Ad-hoc Testing

With this scenario, no particular approach is available. It is a completely unplanned testing method where the insights and understanding of the software tester is the only essential factor.

  • Exploratory Testing

In this type of testing, you need a software tester’s knowledge, creativity, experience, analysis or logical skills, and perception. This test is categorized by poorly-written documentation or shorter execution time. We need human skills for executing the testing procedure in the scenario.

  • Usability Testing

It is the area where you have to measure how efficient, user-friendly, and convenient the product or software is for its end users. Therefore, human observation is the most significant factor, so the manual approach is desirable.



Automation Testing Should Be Preferred For the Following Scenarios:

  • Regression Testing

Automation testing is appropriate here due to frequent code changes as well as the capability of running the reversions on time.

  • Load Testing

Automation testing is the best way of completing the testing proficiently when comes to using load testing.

  • Repeated Execution

Testing that needs repeated task execution is the best Automation.

  • Performance Testing

Testing that needs simulation of thousands of users needs automation.


If you consider all these factors, you can discover the finest enterprise solutions in given testing situations as well as get quality outputs within your timeline and budget.
