Regression Testing in a Microservices Architecture

 It is a testing method that verifies whether new changes or updates made to the code do not alter or modify the existing functionalities of the software application. There can be scenarios wherein modification or amendment can introduce new bugs in the software. Similarly, a slight change in functionality can re-introduce older bugs. Hence, regression testing is conducted to make sure that post-changes done to the application should not alter the core functionality.  

Any new code that has been added to the program should not disrupt the existing features and functions. Whenever there are changes in functionality, upgrades, updates etc., it is better to conduct regression testing. 

 

What is a microservices architecture? 

Microservices refers to an application that has been further divided into autonomous components. Microservices can easily communicate via shared database records, common files, event queues or REST APIs. A major impact on quality can be witnessed by the communication mechanism between microservices. Each microservice will have its own test pipeline, a separate build and its own development team including some of the following test types: 

  • Regression tests 
  • End-to-end/integration tests 
  • Functional tests 
  • Unit tests
  • Manual tests 
  • Exploratory tests. 

 

The relevance of regression testing in microservices architecture: 

There are many developers who have understood the value of microservices and hence is considered to be one of the important architectural approaches. A part of the business is implemented by each microservice, which is considered to be completely independent. Each microservice can be scaled, updated and deployed without other microservices getting impacted and the entire process is automated. 

Continuous delivery plays a crucial role in the development process of microservice-based systems. Software reliability is one of the key challenges of automatic deployment of new releases to the production environment. To ensure software reliability, a regression test is considered to be a viable platform wherein two system versions are compared based on various metrics. The operability of the last developed version is properly tested by regression testing.

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...

Best Practices in Web Application Testing

With an increasing number of users accessing sites on their mobile phones, tablets, and computers, it has become essential for businesses to maximize their web applications for mobile devices. At the same time, each company needs to test the web application ultimately to ensure that it provides richer consumer experience across several browsers and under different conditions. While studying new web programs, QA professionals have to address challenges associated with integration, interoperability, functionality, usability, and security so that the QA professionals should follow simple best practices to test the web applications more effectively. Best Practices for Web Application Testing Nowadays, many businesses opt for responsive website design to make their web programs provide a richer user experience on each device. The new approach requires developers to create websites responsive by employing open web technologies like HTML5, CSS3, and JavaScript. Currently, old ve...

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...
