A Guide to Automated Regression Testing Tools: Beginner’s

functional vs regression testing

Any software cannot run in a completely similar way all the time. Software development activity is always a part of it, where small and substantial changes continue in different phases.

Reinventing products with new features and functions is the only way to sustain in today’s business environment and meet the emerging requirement of the market. Software change brings reinvention.

These changes sometimes affect the functioning and performance of the software. Hence, to avoid any malfunctioning because of the modification and update to the code, regression testing is performed.

Regression testing tools detect any bugs that are caused because of the new changes applied. The old version of the software is tested in the latest version and then compared to see the response of the software’s capabilities in terms of the old functionalities. 

Why do you Need Regression Testing?

Regression testing tools develop the software applications by changing, adding, and eliminating any existing features or functions. For example:

  1. Adding a new feature:
  • When a software application is downloaded, it allows the user to log in through their email credentials.
  • However, the new feature also allows you to log in through Facebook. Here, regression testing comes into the picture and checks if the old log-in with email credentials works accurately or not.

2. Change Requirements and defects are fixed:

  • You log in through user id and password; however, the password option is removed from the first page for faster and straightforward login, this is a change that is executed.
  • While logging in, if the login button pops up an error, the developers resolve the issue. Post that, the automation regression testing is executed to check the fixed log-in functionalities.

3. Resolving operating issues:

  • If the software application is slower while operating, a few codes are modified, and the load time is decreased, let’s say from 7 seconds to 3 seconds. This may affect the software and create glitches in the functionalities.
  • Here again, regression testing tools are executed to check any issue disturbing the operation and performance of the software.  

How to Select Regression Testing Tools for Web Applications?

Once you are sure enough about the duration and the opportunity of the project and you see there is a requirement of upfront efforts to execute automation, you must choose the best regression testing tools that comprise the following features.

  • User-friendly tools anyone can use, a non-technical person can also pull off the test
  • Uninterrupted integration of TFS DevOps incorporation that includes builds and deployments
  • Capable of managing the entire QA process, from test creation to comprehensive reporting
  • A tool that works efficiently in multiple environments, multiple browsers, and multiple platforms and servers
  • The tool should provide keyword and facts-driven testing 

Along with the above properties, it is also imperative that the tool is reliable, scalable, and easy to maintain. Continuous technical support where 24*7 customer service is available. Regression testing tools are full of conceptualization and logic and are community-based.

Things to Consider While Using the Automated Regression Testing Tools:

  • Planning and targeting the QA strategy is a must. Once you have identified the correct tool to optimize the QA procedure, create sufficient time in the product and service’s life process, and find out where the QA fits most appropriately.
  • It is to check if the automated regression testing tools can test every story and if yes, then what kind of approach is required.
  • Identifying those test cases that need an update, modification and automation is the critical aspect and is the most essential at the same time.
  • In those activities where a lot of manual intervention is required, there the chances of human error increase and are time-consuming. Hence, after finding out those kinds of areas where the manual work gets complex to perform, automation is implemented to make the work easier.
  • Early and regular testing is the effective way. When regular testing happens, it detects the bugs at an early stage, and the impact on the project decreases. Prevention is always better than cure.
  • Also, if the bugs are detected early, they consumed less time while fixed. The cost of resolving the issue also decreases compared to discovering a bug at the time of production deployment.
  • Incorporating a QA and development team together makes the work easier. When the Automation and development team work collectively, the process becomes more seamless to achieve the target within the expected time.
  • It also eliminates any miscommunication leading to an increase in the efficiency of the individuals, and the entire development cycle works effortlessly under close monitoring.
  • Building standard quality test data is another significant function. Once the testing is executed and the outcome is up to the mark, using an external data source to check the reliability of automated tests, whether they are reusable and easy to care for or maintain, is essential. To add various test cases and scenarios, files are extended. 
  • Implementing tests considering UI resistant change factors. It means establishing the tests that are not reliable on location-based coordinates, where to find an object, unique names are not mandatory to provide for various control sections.
  • That means the testing is not dependent and limited to any particular data and cannot be collapsed because of any UI change. This way, a stable script is built that works.
