Integration testing primarily focuses on verifying data communication among different modules of the software project.  Integration tests determine the effectiveness and performance of different software modules when they are connected to each other. It rather determines whether a system of multiple modules work together as per the requirements specified. Individual units are culminated together and tested as one unit to validate the performance, functionalities, and reliability of the software. The formal software testing process involves testing different modules initially with unit testing and then moved further for integration testing. Why Integration Testing is Essential within the SDLC? The software has changing requirements and new patches of code are developed frequently. When these patches are grouped together to form one software, this testing process should be taken up. Usually, when complex software is built, it is classified into different modul...

The enterprises of the present digital world are effectively in need of applications to enhance their visibility and productivity. During this application building process, the products undergo several modifications apart from the already listed requirements. And, this way of performing frequent changes can lay down several defects and cause many challenges to the already existing functionalities. This exclusively calls the need for regression testing to validate if the changes made to the application are not affecting the already existing functionalities of the software. Regression testing is one of the very essential software testing types for re-executing the test cases and validating if the latest changes made to the application have not affected the already existing functionalities of the software application. There are several benefits with regression testing such as: ·          Helps in identifying bugs and defects · ...

 What is Unit Testing? Unit testing is one of the software testing types which includes the initial testing phase where the smallest components or the modules of a software are tested individually. With this method of testing, both testers and developers can isolate each module, identify and fix the system defects at a very early stage of the software development lifecycle (SDLC). Primarily, a unit test verifies different behavioral aspects of the system under test and can be broadly classified into state-based and interaction-based unit testing. A typical unit test consists of three phases which include the first initialization phase where it initializes a small piece of an application it wants to test. The second phase is the addition phase where it adds a stimulus to the system under test and finally, the third phase is the result phase where it observes the resulting application behavior. Evidently, if the observed behavior is consistent with expectations, then the unit test pa...

What is Regression Testing? According to Wikipedia, Regression testing is an important type of software testing that revolves around re-running functional and non-functional tests. These tests are conducted to ensure and check the previously developed and tested software still perform well even after a change is made in the software.  Primarily, it checks whether the previous functionality of an application is working as intended even with a new feature added. It checks for any new bug or error in the existing software and is a verification process that takes place in the software. Whenever the new software is released, there is an essential need to test the new functionality. There is a necessity to re-run the old tests to ensure that new software does not re-introduce any old defects or create new ones that might affect the existing functionality.  Though software regression testing seems to be a simple concept, it is quite challenging as it tests the funct...
