Advantages & Disadvantages of Manual Testing

Manual Testing is a process of executing the test cases without using any automation tools. In fact, manual testing is not just running a couple of tests. Rather, it gives human perspective to the software, which never brings it to reality through any kinds of automation. This article will explore the advantages of manual testing that every business should be aware of.

Advantages of Manual Testing

1. High-Level Accuracy

One of the most significant advantages of manual testing is its ability to achieve high-level accuracy. Human testers can detect and analyze complex software behaviors and discrepancies that would leave out automated scripts. This is rather more important to be done at an early stage of development, where the sense of context and nuances in functionalities is important, rather than simple execution of test cases.

2. Real User Experience

Manual testing uniquely captures the real user experience, a critical factor for any business. A software tester can identify potential issues and the improvements required from the end user’s perspective and can also provide feedback on user interface & experience. This insight is invaluable in creating user-friendly and intuitive software products.

3. Flexibility in Testing Process

The flexibility offered by manual testing is unparalleled. Testers can quickly adapt to changes in test cases or project requirements without the need to rewrite scripts, as would be necessary in automated testing. This flexibility enables businesses to respond swiftly to new insights or changes in project scope.

4. Cost-Effective for Small Projects

For small-scale projects, manual testing can be notably cost-effective. Unlike automated testing, which requires significant initial investment in tools and scripting, manual testing can be implemented quickly with fewer resources. It is good and a practical choice for businesses with limited budget and short term projects

5. No Need for Complex Tools

Since the process of manual testing does not have to be complicated with tools or environment, it actually reduces many costs and lowers the entry barriers of a business or team.

6. Better Understanding of Customer Needs

In a nutshell, manual testing pinpoints precisely what customers are going to feel or expect from the system. Testers, by simulating the action and behavior of users, hence, can point out possible places of confusion or difficulty when using the product and provide very valuable feedback for improving its usability.

7. Identifying Visual Issues

For example, in this kind of sight, it will be okay for visual and UI problems running the test. For instance, during the automated execution of tests, a locator does not see very subtle visual bugs, so problems with alignment, colour, or font are ensured for the aesthetics of the final product.

8. Ideal for Short-term Projects

That makes manual testing quite ideal for short term or ad hoc projects. In an instance where very fast development and testing need to be conducted, this form of testing is very agile to be conducted within the needed project timelines.

9. Easier to Learn for New Testers

In general, manual testing is more approachable to the fresh arrival in the area of testing software and, after the testing tools and scripts are mastered, presents itself as quick regression testing to be run at the last minute before a release. Training new testers and increasing the size of the testing team should also be possible when needed.

10. Comprehensive Reporting

Reporting in manual testing is usually taken in the form of elaborate and detailed reporting. Testers report about the smallest details virtually; he lives in the test cases and can give out elaborate recommendations or suggestions in regard to development decisions in the reports in detail, which may be quite helpful for guiding future development decisions.

11. Effective for Exploratory Testing

Exploratory testing is the testing area wherein the testers rely a lot on the creative designing and execution of tests on the fly, guided only by their knowledge of the behaviour of the system under testing. This approach is able to give a tester an opportunity to find issues that predefined tests would never find.

12. Ideal for User-Centric Applications

For applications where user interaction is key, such as mobile applications, gaming software, or e-commerce platforms, manual testing is indispensable. It ensures that the user journey through the application is smooth, intuitive, and free from glitches.

13. Better Handling of Complex Scenarios

Manual testing is better suited for dealing with complex or non-repetitive scenarios. The testers are able to leverage their skills and experience, in this case, to explore and test the complicated features of the software—features that would be really hard to automate in practice.

14. Closer Team Collaboration

In fact, manual testing also puts more effort into working in a team setup and brings about better communication and understanding between the developers, testers, and even the project managers. That means they are likely to churn out well-rounded and cohesive software products.

15. Comprehensive Understanding of the Product

The manual testing of each product ensures the comprehensiveness for the tester of all offered features and products, including all related issues for enhancement. For the quality, the manual testing of each product is very important to ensure comprehension and reliability control.

advantages & disadvantages of manual testing

Disadvantages of Manual Testing

As a result, some phases of the software development life cycle definitely need manual testing; however, many inconveniences, from efficiency to accuracy, and in some cases, scalability, are related to it.

Here are five common drawbacks:

  • Time-Consuming: Each and every scenario needs human intervention in the form of manual tests, so it is way slower than automation, especially for big or complex applications. This can become a bottleneck for testing and increase the overall development cycle.
  • High labor cost: manual testing requires human resources, many of them, which are quite expensive; hence, it results in high labor cost. In long-term projects, this can take vast time and investment required for repetitive manual testing tasks.
  • Prone to human error: Manual testing is highly prone to human errors concerning the close attention to detail, experience, and fatigue levels of the tester. This is because naturally, human beings are forgetful; in particular, in the repetition of testing tasks that are monotonous, one is likely to miss errors and hence end up with inconsequent and inaccurate test results. Test coverage is reasonably high and detailed, although most test specifications target the requirements’ test level. This is the one that is likely, especially in complex systems, to fully test all of the related scenarios and may indeed prove to be impractical—leaving some areas not tested to an adequate level.
  • Non-functional Testing Difficulty: Performance, load, and stress testing provide a better way to pinpoint non-functional testing areas that could be done better. Basically, this necessitates the use of thousands of users in load conditions or the appraisal of how the application is going to respond at critical conditions, respectively, which is hard and inefficient to be done manually. When it is sometimes required to make a test, disadvantages can still be clear: as part of the testing, effectiveness, precision, and thoroughness for more software quality assurance efficiency.

When to use manual or automated testing?

Choosing from a manual to an automated testing process is a very crucial task for software product quality, efficiency, and economy assurance against the rapidly changing world in software development. Manual testing is a procedure of going through the software by hands in search of defects which are not replaceable in cases like exploratory, usability, or ad-hoc testing. It is most appropriate when the test calls for the human element of judgement, e.g., testing the qualitative attributes of the user interface and user experience of an application. The other aspect that makes manual testing preferable, in case there is early-stage-of-development software, while software is still changing, radical changes can take place. More room is left open for immediate feedback on issues which would be overlooked by automated tests.

However, automation testing that uses scripts and tools to autorun tests becomes absolutely excellent, including the conducting of regression testing, performance testing, load testing, and stress testing, where it may be required to rerun tests over a quite prolonged period. Automated testing is very effective for the automation of huge projects, also in testing the scenarios where high precision, responsibility, repeatability, and needed.

The time and effort required for the execution of large test cases is greatly reduced through such automation, thus making it indispensable for Continuous Integration and Delivery practices. Based on the characteristics like size and complexity, in which stage the cycle of development may be, the second part of using manual or automated testing would be decided. A balanced approach is usually that which takes from the manual and the automated the best, putting them to the most effective use.


Among the different advantages that manual testing is tagged with include high accuracy, flexibility, cost-effectiveness, and benefits that one may receive from understanding customer needs. While automation is an important aspect of modern software testing, manual testing continues to play a crucial role in ensuring the quality, usability, and success of software products. Businesses must recognize the value that manual testing brings to the table and leverage it effectively alongside automated testing strategies.


What makes manual testing highly accurate?

Manual testing’s high level of accuracy stems primarily from the human element involved in the process. Unlike automated tests, which follow predefined scripts, human testers can observe, interpret, and judge the application’s behavior more holistically. They can identify subtle nuances, inconsistencies, and complex issues that automated scripts might overlook. This includes understanding the context of the application, interpreting the results based on real-world scenarios, and noticing minor visual and functional defects that could impact the user experience. The attentiveness and insight provided by human testers are critical in ensuring that the software not only functions as expected but also meets the qualitative aspects desired in the final product.

Can manual testing truly replicate the user experience?

Yes, manual testing is particularly effective in replicating and understanding the user experience. This is because manual testing enables the tester to place himself in the shoes of an end-user, interact with the application as a real user would, and give feedback on the interfaces, design, usability, and experience of the user. They can easily spot such problems as poor navigation and elements with bad design and many other different usability problems that automated testing tools would never spot. This is what gives the human perspective on the software, making it built not just functionally but friendly and appealing.

Is manual testing sustainable for long-term projects?

Although many would argue that manual testing is only effective for small-time projects, it also helps in long-term projects a bit. In such projects, a mandatory manual testing activity is, at the same time, also of an exploratory nature. The objective is to continuously discover new test scenarios based on the understanding of the evolved software. Accuracy is of very high importance in these stages, when the test itself is of great importance—most notably when some major release or update is done. Still, from the point of view of long-term sustainability, most often manual testing is complemented by automated testing in order to smooth repetitive and regression testing.

How does manual testing contribute to understanding customer needs?

Manual testing is used for understanding the customer’s needs because it simulates the real environment and behavior of a user interfacing while working with the software. Manual testing allows testers to see how users are going to use your software, what are the issues they can face, and in which part of your application the user experience will be enhanced. This insight will be very essential to be able to create software that complies not only with the functional requisites but with what the users expect, prefer, and find friendly so that customer satisfaction is maximized, and it receives high adoption from the users.

Will manual testing remain relevant in the future?

However, with the development of automation, this future can bear no less relevance to manual testing. In other words, the fact that it can provide a human perspective, realise the experience of a user, and find many one-of-a-kind, and sometimes complex, issues means that it won’t be waning from the software development life cycle anytime soon. Such handling of routine and repetitive tasks might, with greater efficiency, be replaced by automation, while manual testing still stays as a major part toward the overall quality and user-friendliness of the software product. The future of software testing, balanced between the two, is arguably looking at a balanced combination of both manual and automated testing approaches to ensure the benefits of either test technique are optimally realized.
