What is Unit Testing and its Tools

Software testing is the major requirement for the present digital era for delivering quality software applications. It is the practice of helping many enterprises in ensuring that the developed application is as per the business and user requirements. Thus, it is essential for the teams to validate every testing practice from the initial stage, i.e. from the Unit Testing phase itself.

Unit testing is considered to be the first software testing phase in the software testing lifecycle (STLC). It is practiced before integration testing and helps in validating the correctness and completeness of the smallest component. Since it is the first testing practice, it is essential for the teams to perform this with clear understanding so that testing of applications is efficient from the first phase itself.

What is Unit testing?

Unit testing is the initial software testing phase where the smallest individual components of a software are tested and validated to ensure each unit of the code performs as expected by the enterprises or the clients. It is performed during the development phase of the application by developers.

3 Types of Unit testing

There are three types of unit testing; and each of the testing types is having different properties.
• Gray Box Testing: This unit testing type is used for executing test cases, test suites, and to test various other methods.
• Black Box Testing: In this unit testing type, the testing teams are allowed to test the user interface of the application along with the output and input.
• White Box Testing: In this unit testing type, developers test the functional behavior of the application for validating their execution.

5 Unit Testing Tools to help you

NUnit: This is a unit testing framework widely preferred for all most all .net languages. It is an open-source tool allowing developers to write scripts manually and perform data-driven tests.
JUnit: This is a free testing tool used that provides assertions for identifying test methods. With this tool, the testers are allowed to test the data first and then insert the code.
HtmlUnit: This is an open-source Java library tool that supports JavaScript and provides other GUI features such as tables, forms, links, etc.
JMockit: This is an open-source unit testing tool that allows mocking API with verification and recording syntax. With this tool, the teams can obtain features related to code coverage, data coverage, and path coverage.
PHPUnit: This tool is widely preferred by the PHP programmer. In this tool, small portions of code known as units are considered for testing each of them separately.

Unit testing is the first software testing phase and also an important phase to ensure the further testing phases are functioning well. Leverage unit testing services from next-gen QA testing services provider to ensure each of the smallest code is performing as expected.
