What are the best practices of unit testing?

Software testing has become an integral part of the software development process. Since enterprises want bug-free and high-quality software, it is very necessary to do software testing at each stage of the software development lifecycle. There are varieties of tests that are performed at each stage of SDLC. Unit testing is one such software testing type that performed at the initial phase of SDLC. Let us now try to understand some of the best practices of this testing type in detail.

What is unit testing?

It is the first level of Software Testing Life Cycle (STLC). In this individual components/units of the software are tested to validate there are no defects in the modules/components of the software and they perform as expected. Usually, this testing is done by the developers in the early stage of the Software Development Lifecycle to remove any defects in the initial phase itself. In this, each unit of the system is isolated to identify, analyze, and fix the defect.

Why is unit testing required?

Below listed are some of the reasons why this test is required:

·         It helps to find and fix bugs earlier in the SDLC

·         It reduces complexities present in the code

·         It helps businesses to save time and money

·         It aids in the development of quality product

·         It enhances code coverage

What are the best practices of unit testing?

1.       Test should be reliable: The unit test should fail if the code is broken and should pass if the test is not broken. Basically, the test results should depict clear and accurate conditions of code. It does not depict so, the test is unreliable.

2.       Test should be easy to read and maintain: Usually, the production codes are updated from time to time. And multiple developers work on single software. Therefore the codes should be easy to read and understand not only for those who wrote it but also for the developers

3.       Always verify one use case per unit test: It is always advisable to check one use case per test. This means using a minimum of assertions per test. This makes the test easy and more understandable.

4.       Properly name unit tests: Giving a good test name makes it easy to maintain. Test name should be self-explanatory and should provide information about what is being tested, conditions under which it is being tested and expected results

5.       Always isolate the unit test codes: Testing should be done in an isolated condition and should have no dependency on external factors or environments. Isolation helps in the easy identification of defects and easy fixing of bugs.

6.       Automate the unit test: Automating the unit test helps in better planning and action. Running tests daily, every hour helps in building stable software and gives reports code coverage, performance, frequency of test, etc.

Conclusion: As businesses continue to conduct unit testing of their software it is very important that some best practices should be considered. In this article, we have mentioned some of the best practices that businesses should look at in order to achieve effective results from the unit testing process. Leverage unit testing from a next-gen QA and software testing services provider to get high-quality software.
