Regression testing is one of the most critical aspects of quality assurance. It helps developers to check for issues that are introduced by new additions to their codebase or due to a bug fix.
The aim is to check all those pieces of code that could be impacted due to these changes. It goes without saying that adopting effective regression testing strategies can save development teams hundreds of hours of debugging.
Before taking up the task of regression testing, the team needs to define the test framework that they plan to use. This framework should contain all those test cases that could have been impacted due to the changes.
Moreover, the selection of appropriate test cases and prioritizing error-prone test cases could take up a lot of time and resources. Hence, automating regression testing is necessary to stay in bounds within the strict timelines.
Testsigma, a tool for automated regression testing, provides a cloud-based test automation ecosystem which contains all the essential elements that would be required for automated regression testing. It is an ideal automated regression testing tool which suggests affected or relevant test cases after there is a feature enhancement or bug fix.
It lets you run your regression tests automatically within a sprint. With Testsigma, you get the following features to improve your regression testing experience.
- Automates your regression tests using simple English.
- AI creates regression test plans containing all the affected test cases.
- It helps you to maintain or heal your regression tests automatically for any changes in UI elements.
- Reduces your feedback time by executing multiple tests in parallel.
- Provides continuous integration to run test cases after every new build.
- Generates comprehensive reports to determine the release readiness.
Here are a bunch of factors that make it easier for you to perform regression testing using Testsigma.
Introducing new features to the code could unintentionally affect pieces of codes in different modules. This is largely due to the dependencies between the modules. Such regressions need to be resolved within the sprint to ensure that the bug doesn’t reach the production level code.
Testsigma provides AI-driven features that can automatically detect test cases that could have been affected due to such changes.
For example, if you want to change a certain UI component, it would detect all the Test Cases that are dependent on this UI Identifier and lets you run regression tests on all these Test Cases.
To see the list of all such affected Test Cases, click on the UI Identifiers button present inside the Test Development view on the left pane and click on the View button under the Affected list parameter of the UI Identifier on which you have made changes.
This will pop up a list of Test Cases that could be affected due to the change in the corresponding UI Identifier.
You can click on the Run Now button to execute all such Test Cases.
Testsigma allows you to prioritize and filter your test cases based on critical modules, test case type, the customer reported bugs and numerous other custom filters. This will help you to create a lean optimized test plan.
For better regression testing results, you should make sure that you select all the integration test cases. Integration test cases are those which focus on the interface via which 2 modules communicate with other and hence, are more prone to bugs.
Also, you should select a combination of both passed and failed test cases to get a birds-eye view of the issues leading to regressions in your application.
You need to prioritize your test cases based on criticality and impact of bug fixes for enhanced regression testing.
To filter test cases, Click on Test Cases button under the Test Development panel. Click on the Filter button on the top right corner of the page.
Here, you will have the options to filter your test cases based on certain parameters. You will have options to select your test case type (Unit Test, Integration, Functional, Non-Functional, User Experience).
You can also select test cases based on the priority assigned to them.
Once you select all your test cases, click on the filter button on the bottom right corner.
After you have selected all the required test cases, you can click on the Test Suite button to create a test suite containing all the selected Test Cases.
For test suites that contain a large number of test cases, it might consume lots of time and resources to perform regression tests on them. You can use the parallel execution feature provided by Testsigma to reduce your execution time considerably. It helps you to shorten the feedback loop, thus allowing developers to find the bugs faster and reduce the shipping time.
To perform automated parallel testing, click on the Test Plans button inside the Test Development menu in the left panel. Here, you can see all your existing test plans (if any). Click on the Test Plan button on the top right corner of the page.
Here, you need to enter all the details and specifications that you would like to set for your test plan. Make sure that you select Parallel Testing under the Test Plan Type dropdown menu.
Click on the Select Test Suites button to select the test suites on which you want to perform parallel regression testing.
You need to select the test suites and click on the Add button to select the test suites. Click on the Done button once you are done.
After you have entered all the details, click on the create button to build the test plan for parallel regression testing.
To run the Parallel Test, click on the Run Now button next to the test plan that you created.
Testsigma allows you to schedule your test executions to run them periodically without any kind of manual intervention. Scheduling automated tests add another layer of automation to your regression testing making it easier for you to detect regressions in the code modules.
You just need to determine the execution schedule for regression testing and the frequency of the test executions and then you can easily run scheduled tests on a daily or weekly basis. Parallel execution along with scheduled automated tests helps you to create robust and automated regression tests.
To schedule a Test Plan, click on the Run Later button just next to the Test Plan which you want to schedule.
You will see that a new pane pops up. You need to enter details such as the name, description, frequency, scheduled date and time of the Test Plan. Once you have entered all the details, you can click on the Create button.
When you click on the Schedules button, you will see all your schedules listed there.
5. Quick, Actionable and Drill-Down feedback reports
Testsigma tool provides detailed feedback reports which help you to clearly identify failures and take action on the broken code. It provides comprehensive test reports with a drill-down approach which helps you to analyze your test results quickly, easily and effectively. The organization of test results on the test suite level and test environment level helps you to determine the failed tests quickly with actionable feedback.
It provides a pictorial representation of the number of test cases passed and failed along with the screenshot captured for each test step. You can also watch the video for the entire Test Step execution. Moreover, you get a detailed description of each test step.
Testsigma is a cloud-based testing tool that supports web, mobile and API test automation, allowing you to easily identify bugs that are introduced as a result of the changes that are made in the code. It hosts and runs your automated test cases on the cloud and allows you to schedule them as per your convenience and requirements.
There are a bunch of factors, as discussed above, which makes it easier to perform regression testing on your applications. It’s a fact that the effectiveness of regression testing certainly depends upon the selection of test cases for execution, which also depends upon the criticality of the selected module or component.
Testsigma allows you to detect vulnerable test cases which could be impacted by a specific change in the code through AI-driven solutions thus reducing manual intervention. Having extensive and automated regression Test Suites definitely helps to mitigate risks and Testsigma allows you to do that seamlessly.
