Advantages of Manual Testing /Functional Testing

Manual testing refers to the process of testing software manually, without the use of automated testing tools. While there are many advantages to automated testing, there are also many advantages to manual testing, especially in certain situations.

In this article, we will explore the advantages of manual testing in detail, and discuss the situations in which it can be most effective. We will also examine some of the challenges associated with manual testing, and suggest strategies for overcoming these challenges.

Advantages of Manual Testing


One of the biggest advantages of manual testing is its flexibility. Because manual testing is performed by a human tester, the tester can adapt and change their testing approach based on the specific requirements of each test case. This flexibility makes it easier to test scenarios that may be difficult to automate.

For example, manual testing can be useful for testing scenarios where the expected outcome is difficult to predict or where the steps required to reproduce the scenario are complex. In such cases, a human tester can use their judgment and experience to guide the testing process, and can adjust their approach as needed to achieve the desired outcome.

Exploratory Testing

Manual testing is particularly useful for exploratory testing, where the tester actively explores the software and tries to find defects. Exploratory testing is a type of testing that is often performed in conjunction with other types of testing, such as regression testing or functional testing.

Exploratory testing can uncover defects that may not be caught by automated tests, especially if the defects are related to usability or user experience. By actively exploring the software, the tester can identify potential issues and suggest improvements to the development team.

Early Detection of Usability Issues

Manual testing can detect usability issues early in the development cycle. Usability testing is an important aspect of software development, as it helps ensure that the software is easy to use and meets the needs of its users. Manual testing is particularly useful for detecting usability issues because it allows the tester to experience the software from the perspective of the end user.

For example, a manual tester can identify issues with navigation, layout, or user interface design that may be difficult to detect with automated tests. By identifying these issues early in the development cycle, the development team can make changes to the software before it is released to the end user.


Manual testing can be more cost-effective than automated testing in some cases, especially for smaller projects or projects with a limited budget. Automated testing can be expensive to set up and maintain, and requires a significant investment in time and resources.

Manual testing, on the other hand, is relatively simple and straightforward, and can be performed by a single tester or a small team of testers. This can make it a more cost-effective option for smaller projects or projects with a limited budget.

Human Touch

Manual testing can provide a human touch to the testing process, which can be particularly valuable in projects where the end user is a human. By using a human tester, the testing process can be tailored to the needs and expectations of the end user.

For example, a human tester can provide feedback on the user interface design, the ease of use of the software, and the overall user experience. This feedback can help the development team improve the software and make it more user-friendly.


Manual testing requires less preparation and setup than automated testing. Automated testing requires the development of scripts and the configuration of testing tools, which can be time-consuming and complex.

Manual testing, on the other hand, is relatively simple and straightforward. It requires only a tester, a test plan, and a set of test cases. This simplicity can be useful in projects where the testing requirements are not complex.

Contextual Understanding

Manual testers can bring their contextual understanding of the application to bear during testing.
