What is Unit Testing : Advantages & Disadvantages

What is Unit Testing?


This is a type of testing which is done by software developers in which the smallest testable module of an application - such as functions, interfaces, or procedures - are tested to ascertain if they're fit to use.


The objective of unit testing is to split each portion of the source code and also check that each part works properly. This ought to mean that if any group of input is fed to function or procedure, it should return an expected output.


Advantages of unit testing:


  1. Defects are observed at an early stage. As it is done by the dev group by testing individual pieces of code prior to integration, it assists in fixing the issues early on in source code without impacting other source codes.
  2. It will help maintain the code. As it's accomplished by individual programmers, stress is being put on making the code interdependent, which then reduces the chances of impacting other sets of source code.
  3.  It aids in cutting the cost of defect fixes because bugs are found early on in the growth cycle.
  4.  It assists in simplifying the debugging process. Only the latest changes made from the code have to be debugged in case a test case fails while doing unit testing.


Disadvantages of Unit Testing


  1. While there are benefits to unit testing, there are some disadvantages, too. Code testers will tell you there are a few problems with UT that have to be considered.
  2. You usually have to compose one or more unit tests determined by how complex things are. While the test code should be rather easy, this testing method is still more work and more code which means more hours and more cost.
  3. Unit tests are debatable when you have to check your user interface (UI). They are good for when you need to check business logic execution but not good for UI.
  4. There is a circle of thought which unit tests are debatable to get a product's structural layout. They solidify the arrangement of code which means change can be problematic when required.


Conclusion


While there are strong proponents on each side of this UT problem, the middle ground says to use it within reason. Should you include a unit evaluation best practice program that creates limitations and guarantees worth and precision, it makes sense to use it to its entire potential.


Many will state that using unit tests prior to integration testing is great if it does not hijack the general process.


No matter what code you are testing, finding bugs and errors beforehand is helpful. If you are working with a fantastic QA group, covering your bases in UT should be efficient and useful if you know what to avoid.

Explore the Basic Types of Software Testing

Software testing is a vital procedure in the IT industry. The method involves testing the features and validating the operation of the program effectively. This is a very important branch of this IT field since any applications created are tested to make sure its effectiveness and proficiency based on its specifications and testing strategies. It also helps to detect any type of defects and flaws in the functioning of the applications which in turn helps the programmer to take the mandatory measure and create software with flawless operation. There are different types of software testing done based on purposes. Every type is this classification relies upon its function and importance in the testing process. There is functional testing that is done in order to test any kind of functional defects in the software and ensure proper operation. Then there is performance testing that is principally done when the software is not functioning correctly.  Under such a situation tes...

What is test automation & what are some ways of automating software testing?

Software development is one of the most important activities in the Information technology domain. From small to large-scale complex software applications, Software Development Life Cycle (SDLC) process needs to be implemented strategically. To ensure that software is bug-free and of the best quality, built according to user and business-specific requirements, software testing is implemented. Test automation is one of the most important components of software testing. In this article, you will get to know about test automation and some of the ways to automate software testing . What is test automation? It is a process where automated tools are used for efficient software testing activities. It helps in managing test data, running tests and leveraging results for developing a high-quality software product or application. Much of the manual requirements are relieved through the tactical implementation of test automation. Test automation is also referred to as “automation testing” or...
