What Are The Disadvantages Of Unit Testing

1. What Are The Disadvantages Of Unit Testing?

2. What is unit testing? There is no doubt that unit testing is considered to be productive and rewarding. But, on the flip side, it comes with a few disadvantages too. This does not mean ignoring unit testing, but, rather being more strategic and aware of the outcomes of unit testing, thus saving time and cost. The objective is to provide knowledge and let the developers and testers know as to how unit testing can prove to be less effective in certain scenarios or may not be able to provide justifiable testing outcomes. In this article, you will get to know as to what are the disadvantages of unit testing.

3. Following are the disadvantages of unit testing It is a time-consuming process: Even if one small unit test needs to be developed, it takes quite a bit of time and when it comes to larger ones, the time taken is obvious. Developers need to spend time on research, experimentation and figuring out the structure of the test method and what are the parameters, methods and objects, the test case needs. The time that is invested is not only on developing the unit test, but also on analyzing the best way to use the unit test. 2. The issue with GUI code: When GUI code is being developed, the key thing is to test the code and make sure that it is working as expected. When it comes to unit testing, GUI code is not in line when it comes to the testing part. The complexity of the GUI code is one of the reasons that can be cited. Another key reason is the way the system is being interacted with the GUI code. 3. Quite complex to work upon legacy code: When it comes to performing unit testing on the legacy code, it becomes quite vague because there is no specific beginning and there is no practicality of tests. In order to be clear as to when testing should be initiated, there should be clarity on the specific parts of the code that needs to be tested. Upon that, if the developer does not have a good hold on the legacy code, then it becomes even more difficult to work on the testing process.

4. 4. The maintenance factor: Unit testing can prove to be laborious and time-consuming. One of the misconceptions is that labor and time are only required, when the unit test is initially created. But, if there is a need to consistently test interactive and complex systems, then the team members need to put in a huge amount of effort and time to maintain ongoing tests. Depending upon the code, the amount consumed for maintenance can be determined. 5. All errors cannot be detected: Though unit testing is conducted to test the individual units of a code and to a great extent many of the errors are identified, but, not all. The aim of software testing is to reduce and eventually eliminate defects and bugs from the system or application. But, to attain this specific objective, there is a well-defined testing strategy that needs to be followed. This also means to detect all the errors, key testing types such as penetration testing, performance testing, system, testing, integration testing and acceptance testing should also be taken into consideration.
