QA Dilemma: Manual Test vs Automated Test
Testing is one of the most important aspects of software development. In simple terms, testing means testing product software to detect any errors or bugs. The quality of the software product is determined by the level at which it meets the stated requirements, user expectations, and requirements.
Manual testing is performed by testers to check for software errors. It is done in accordance with a written evaluation system that includes a set of different test cases. Testers work as first-time users and analyze software product behavior. They should express disagreements and inconsistencies with expected behavior and report errors to developers.
QA dilemma analyzes how easy it is to use, and how simple and useful the software or product is for the end-user. In usability testing, human testing is an important factor, which is why this type of testing should be done in person.
In this case, the analytical and intellectual skills, knowledge, art, knowledge, and understanding of the examiner are must-haves. Often this type of test includes poorly defined texts and you can’t afford to spend a lot of time running. This situation requires the skills and knowledge of the person to perform the tests.
Test-Driven Development cannot exist without automatic testing. In TDD first, you write the Unit Test and the actual code appears. Once the engineer has completed the code, the time for the unit test to be executed arrives. Then this code is redone or other tests are added and activated, where compliance depends on the result.
Automatic testing is ideal for retrofit tests because engineers change the code from time to time and the descent can be done quickly.
Includes UI testing to see if the GUI meets all the required requirements.
Where should you use a manual test?
- Testing – This is the first test of completely new features. Since the function involved is new and no ready-made test cases are available, performing this type of test is not possible.
- Visual GUI and usability testing – Testing user interactions and user information involves visual testing and requires personal observation.
Where should you use the automated test?
- Smoke testing assesses significant performance. It is usually the same and reused.
- The reversal test re-evaluates existing performance after updating the application itself or the operating system and is designed to detect if a conflict is occurring.
Advantages of automatic testing
Automation saves time on some time-consuming things
Testing software can be time-consuming and often repetitive for example, when testing whether an app is performing the way it should after it has been updated to the app itself or the operating system.
The default can help fight human errors
People make mistakes and may miss things. The machines, if properly designed, make no mistakes. And if there is an error in the test code or its execution, you will know as soon as the test will fail.
The default can save you money
This seems easier when QA dilemma spends less time on the job, less expensive. In discussions of manual testing compared to default, this fact often emerges.
Disadvantages of automatic testing
Automatic testing is more complex than manual testing
Texts are not written. QAs write their own tasks for each task, and this means that the QA automation engineer needs editing skills and knowledge of at least one programming language.
Automatic testing is not the answer to all problems
There are things that automatic testing can do with current technology.
Advantages of manual testing
Manual testing is easy to use
It is much easier to equip your company with qualified QA professionals as opposed to automated professionals. Many self-paced tasks can be performed without access to the code and without any coding experience.
Manual testing is the right choice for the most difficult tasks
When you consider the most complex features, the time to do the actual tests and the cost of doing so can sometimes be less than the time and money required to write the default scripts.
Self-assessment is best suited for specific tasks
Visual interface design, user information, and usability have not yet been tested for scripts. This test requires a personal response – sometimes from a quality assurance specialist, sometimes from a user test team.
Disadvantages of manual testing
Self-examination is slow in nature
The same task that can take a person’s QA a few hours or days to complete will take just minutes or seconds on the machine. Computer systems and text scripts process data faster than humans.
Self-examination is often flawed
People may miss details when it comes to repetitive tasks, such as reviewing a feature after each review. Spreading attention over multiple points in a single task can also lead to a problem in QA, making test results less reliable.
Over time, manual testing alone can be very expensive
It is true that with automated testing a company needs to invest a lot of money sometimes from when you leave, both in software and in hiring qualified staff.
After all the discussion the main point is that there is no answer to the question if the automatic test is better than the manual test or vice versa. Selection should be made based on the project you have, and the best way is to combine both manual and automatic testing as we do in anise.
