Manual Testing Activities: Advantages and Disadvantages

Benefits of Manual Testing Activities


Manual Testing is a fundamental part of every effective programming venture. Divergent variables such as venture necessities, course of events, appropriateness and mastery dictate how the manual testing activities will be performed (either manually or automated). The three fundamental elements to the testing process include time, cost,. and quality. Conducting a successful test necessitates limiting the amount of time and resources expended throughout the process.


Manual vs. Automated Testing

Manual testing is conducted by an individual with no assistance from instruments or otherwise. On the other hand, automated testing requires the use of devices, contents, and programs.


Manual and automated testing procedures are mutually exclusive of one another, each employing different techniques and strategies, including discovery testing, reconciliation testing, white box testing, execution testing, framework testing and load testing, to name a few. Some of these techniques work best for manual testing activities, while the application of others are best for automated testing.


Note the advantages and disadvantages of each below:


Manual Testing

In manual testing, a product is checked against non-practical and utilitarian prerequisites manually, usually supervised by a quality affirmation group.

This method involves a bit of beta-testing, like running the application on various gadgets to discovering possible deviations from the initial prerequisites. The quality group uses some redefined test cases to measure quality, keeping a watchful eye on any possible blunders or defects with the application’s utility, UX, and outline.

Manual Testing Activities


Requirements Analysis:

This is where the analyzers familiarize themselves with the app’s details so as to identify any errors.


Test Cases Creation:

With the useful details in hand, the testing group begins a series of experiments on the item, covering every real component and plan components inside the product.


Conducting the Tests:

Tests are carried out one after the other, armed with a good understanding of the product and how it operates.

Logging Bug Reports:

As the tests are conducted, the existing bugs and blunders are noted, logged, and presented in a detailed report including recommendations for remediation.

Advantages and Disadvantages




Manual testing is Consistent with Life Testing

Manual testing seeks to use the product in a perceived real-time, mirroring the exact environment in which the application will be utilized. As a result, a preventative discovery of potential bugs or blemishes can be identified prior to the client launching the application.


Exhaustive Plan Audit

Obviously, an automated system can not offer criticism regarding the application’s look and feel, unlike a cognitive, real-life perspective. An individual’s honest feedback about the physical qualities of the application is usually thorough and insightful.


Cost Effectiveness

When it comes to additional device usage, the manual testing process saves resources. Also, no pre-requisites, certifications, or discernment applies to the candidate(s) interested in performing the review – anyone can do it. Friends and colleagues, for instance, could be enlisted to perform quality checks.

Expanded Adaptability

With manual testing, there is the flexibility advantage where adjustments can be done quickly and on the go.



Risks of Disappointment

Since manual testing rests on the shoulders of the person responsible, the findings may prove less precise; with an exhaustive process. Minor outline blunders and blemishes may not be identified due to the margin of human error. Further, when a QA group is conditioned to a product and the process, they may lack the foresight in identifying new bugs.


Requires More Time and Assets

Manual testing can be a slow, meticulous process. The simplicity of automation testing lies in the usage of just one single machine to run all tests. The need to expend human resources is only in the instance of each set of tests. As your program advances, so does the increase in costs and expenses.

Lack of Manual Intervention 

There are a few limitations to the manual testing approach, as in the instance of direct load and execution testing. In this instance, many users, analyzers and gadgets are interconnected in tandem to run the program.

Also, Manual Testing may produce inefficient, unreliable or ambiguous results, with particular difficulty in testing reusability. Large projects with short deadlines are not suitable for manual testing. Load and performance testing is wholly impossilbe to employ manually.


Automated Testing:

Automation testing requires executing pre-scripted tests on a product before discharging it into creation. Manual and mechanized testing has a fundamental distinction in techniques. Test robotization apparatuses are utilized in automated tests to perform tests, reporting of outcomes, and comparison with prior trials. Involving less human touch, it takes different test reruns as the need arises.


The Ups and Downs of Automation:




Speed and Efficiency

Since tests are conducted by programs and instruments, robotized testing takes less time and energy. Once set up, the testing system automatically does the work, with the test reuse in perspective. The tests run concurrently on different machines and programs, reducing testing time and exertion. Computerized testing can be accurate since it depends solely on calculations.



Robotization may be more cost-efficient in the long run. Simply set up a computerized structure once and more experiments can be included as the item develops. Additionally, when the tests needs to be run over and over, robotization saves time and cash for the QA group, while ensuring reliable outcomes.

Straightforward and Fastidious

Unlike the manual procedure where only the analyzer can see prompt outcomes, automated testing uses committed devices for QA robotization. Everyone on the team has the capability to see progress and resulting outcomes. Robotized testing also enables detailed application testing of aspects that cannot be tried physically.




Requires Additional Cost

An automated system requires a custom robotization structure, regardless of the nature of the device. A legitimate testing process is also rather costly to establish, yet advantageous as the apparatus and assembled structure can be reused for other tests. Yet underlying system costs are weighty, as well as regular maintenance expenditures.


Lack of Human Input on UI and Usability

Machines lack the power of vision, and subsequently cannot provide an unprejudiced analysis on the application’s UX or plan. The automated systems would simply check each component against pre-established parameters.


Limitations and In-Built Issues

Preset testing machinery often does not have the range of parameters the user needs to test the product. These parameters can be extended and modified by the user to a limited extent. Additionally, these programs come with their own bugs and issues, which if left undetected, may negatively affect the testing procedure. Here are a few other points on the downside of automation:

  • Automation requires substantial investment in skills and tools
  • Automation cannot replace the human intellectual skills factor needed for evaluating the software’s UI or UX
  • It requires basic programming knowledge
  • May require training for manual test resources
