Regression Testing Service implementation at Testvox

What is Regression Testing?

A type of software testing that assures the consistent functioning of all previously existing features and functionalities of an application software after a new feature has been launched into the application or a code change on behalf of this application software has been made is called Regression Testing. We re-execute all test cases regarding the existing features and functionalities of the application software to ensure this. To ensure consistency, we again test those parts of the application software components unaltered by the latter code changes.

Regression Testing also ensures the non-reappearance of the bugs already fixed before the code update. It is a vital part of software maintenance. The number of test cases mapped to regression testing will increase after each code update in the software application. This is due to the accommodation of new test cases corresponding to the newly introduced functionality changes and features. When conducting regression testing next time , execute these new sets of test cases in addition to the already existing ones.

Why Regression Testing

We need to plan this testing strategy when

Regression Testing Methods

Basically there are 2 methods

(i) Manual Regression Testing, and
(ii) Automated regression testing.

We initially prepare test cases that corresponds to the functionalities and features of the application software. Each test case represents a sub-functionality, functionality, or feature. It consists of a sequence of events to be executed that are numbered stepwise. We manage the created test cases using a testing management tool.

Manual Regression Testing:-

The Software Testers create the test cases related to the areas of the application software given for testing. They proceed with running the application stepwise as entered in the test cases. The software testers execute test cases one by one, report the bugs found to the clients, and keep track of them using a testing management tool. Manual testing is advantageous when,
(i) We test the functionalities and features that change frequently,
(ii) The product given for testing is not yet stable, and
(iii) The functionalities and features that are difficult to be automated are tested.

Automated Regression Testing:-

To make this type of testing possible, we need to fulfill the prerequisites listed below.
(i) We need to run the sequence of events incorporated into each test case in the application software given for testing. An automation tool should record them simultaneously. We must save these recordings and ensure they are ready for execution at any time, or

(ii) We need to write series of scripts corresponding to the sequence of events incorporated into each test case. The automation tool we use should support the scripting language used to write these scripts. We should save them and make them ready for execution at any time.

We execute the series of pre-written scripts or run the saved recordings for automated testing. They correspond to test cases belonging to the modules of the application to be tested after a code change.

Automated Regression Testing has the following attractions.

(i) Manual regression testing process is slow and time-consuming and can be tiresome and error-prone. Automation of regression testing overcomes these vulnerabilities and the recordings or scripts can be run continuously for days with the automation tool without exhaustion unlike humans. This makes faster delivery of the product possible.
(ii) The software testers can be allocated to work on more valuable tasks as automated regression testing requires little human intervention only.
(iii) This type of testing is the best option to test scenarios or functionalities that are predictable or stable and frequently repeated.

Implementation of Regression Testing at Testvox

Testvox handles both manual and automated regression testing based on
(i) Requests received from clients, or
(ii) As per requirements identified while proceeding with the testing of the application software.
The automation tools used mostly are Selenium WebDriver for testing web applications, WebdriverIO for testing both mobile and web applications, APPIUM for testing mobile applications, etc.
Test cases are created module wise initially based on the requirements when an application software is entrusted with us for testing. We then decide the testing method that we follow.
(i) If clients suggest or we decide on manual testing based on the testing project, our software testers will execute each test case stepwise on the software application given for testing.
(ii) If we recommend automated regression testing, our software testers will create test scripts.   An alternate is to execute the stepwise actions in each of the test cases ,record them using the automation tool, and save them. We run these test scripts or recordings on the application software during automated regression testing.

We will report bugs found after the completion of the regression testing. On rectification of these bugs, the whole collection of created test cases regarding or related to the modules where bugs were found will be executed again either manually or using automation tool. This ensures the absence of all previously identified bugs and new bugs.

We will deliver the test scripts created corresponding to the formed test cases to the clients upon their request. We will also impart the knowledge on their functioning to the clients through knowledge transfer or mentoring sessions. So even after the completion of the contract with <a ” href=”https://testvox.com/”>Testvox, the clients can utilize these test scripts on their own when required for testing their software application.
