What is regression testing?

Regression testing is an important software testing type that revolves around re-running the functional and non-functional tests. A regression test is done to verify that the existing product remains unaffected after frequent code changes or updates. It helps to check that the previous functionality of the software works as expected even when new features are added or code changes have been introduced.

Regression Testing

What is unit testing?

Unit testing is a software testing method, where individual units of the software are isolated and tested. It is done to check that each unit of software works as expected. Unit testing is the first level of software testing. It is performed by developers during the development or coding phase.

Benefits with Regression Testing taken up in Agile Environments

Agile and DevOps have reinvented the way how software is developed, tested, and delivered to the customer. Agile methodologies focus on improving the quality of software by working in sprints. Regression testing in agile ensures continuity of business functions by focusing on the development of new features in the sprint along with the overall functionality. Let us now take a closer look into what is meant by regression testing in agile and what are the benefits associated with it.

What is regression testing in agile?
Regression testing is a software testing type that is performed to verify the impact of any new code on the existing functionality of the product. This method of testing allows testers to identify bugs or errors in the software whenever code changes are made. It ensures that all the features and functionalities of the product remain unaffected and work seamlessly even when code changes are done. Regression testing is a black-box testing method that ensures any frequent code changes made in the product will not impact the system’s functionality.

What is the significance of regression testing in agile?
Agile methodology focuses on faster and iterative development where the product is developed in sprints and features are rolled out in each cycle. Ideally, testing cycles are kept short to ensure a proper balance between the sprint development and iterative test cycles. In an agile environment, developers roll out features quickly, and therefore it is necessary that testing should go hand in hand to deploy features after testing them
In agile regression testing, the testing is done on new and old features, and simultaneously the developers develop new features or make any addition or improvement in the code
Thus, regression testing has its significance, and this testing process ensures functionalities remain unaffected for every build. This regression testing process is critical for the product’s success as it ensures all functionalities work as per the given requirements in an agile environment.

What are the benefits of regression testing in agile?
Below mentioned are some of the benefits of regression testing in agile:
• It helps to build a stable product as testing is taken up in sprints along with development.
• It ensures that the newly developed or existing functionalities remain unaffected and works as per requirements.
• Helps in early identification and resolution of defects
• Automated regression tests in agile reduces the re-work and frees up testers so that they can focus on other important tasks
• Helps in improving the overall quality of the product and ensures a great user experience

In an agile environment, iterative changes are made to the product. Also, there are more frequent build cycles and continuous changes are added to the application. Therefore, to test these frequent changes, software regression testing should be taken up in agile practices.
Thus, for successful regression testing in agile businesses should leverage regression testing from a next-gen QA and software testing services provider. Get in touch with our experts to know more.

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.

Agile methodology is one of the most widely accepted approaches of software development and it is considered one of the favorites among the IT industry. Today, almost every IT organization seems to have adopted and practice the agile process for once at least. But what makes agile methodology or agile software development so important? Well to answer this, we need to get into the basics of agile methodology.


What is an agile methodology?
Agile methodology is a process in which agile teams break the project into smaller stages and make continuous iteration with the help of constant collaboration with stakeholders. In agile methodology, development and testing go hand in hand, unlike the waterfall model.

What is agile software development?
Agile software development is focused on iterative development.

Key To Successful Unit Testing

Unit Testing is certainly not a new concept. It’s been there since the beginning of programming. As a rule, engineers and in some cases White box analyzers compose Unit tests to improve code quality by confirming each unit of the code used to actualize utilitarian necessities (otherwise known as test drove advancement TDD or test-first turn of events). 

“Unit Testing is the strategy for checking the littlest bit of testable code against its motivation.” If the reason or prerequisite flopped then the unit test has fizzled.

Importance Of Writing Unit Tests

Unit Testing is utilized to structure strong programming parts that help keep up code and kill the issues in code units. We as a whole know the significance of finding and fixing abandons in the beginning phase of the product improvement cycle. This testing fills a similar need. 

It is an indispensable piece of the nimble programming improvement process. At the point when a daily form run unit test suite should run and report ought to be produced. In the event that any of the unit tests have fizzled, at that point, the QA group ought not to acknowledge that work for confirmation. 

In the event that we set this as a standard procedure, numerous imperfections would be trapped in the early improvement cycle, sparing a lot of testing time. 

I realize numerous engineers hate to compose unit tests. They either disregard or compose terrible unit experiments because of tight planning or absence of reality (yea they compose void unit tests, so 100% of them pass effectively;- )). It’s essential to compose great unit tests or don’t think of them by any stretch of the imagination. It’s considerably increasingly essential to give adequate time and a strong situation for genuine advantages.
