Optimizing Software Testing with Parallel Test Execution in Testsigma
In the field of software testing, speed and efficiency are critical elements that can have a significant impact on project success. Parallel testing is an efficient approach to shorten testing cycles and reduce product time-to-market. In this article, we’ll look at parallel testing and how it may be used in Testsigma, a cloud-based test automation tool. We will also review the advantages of parallel testing and how it may help improve your software products’ overall quality.

What is Parallel Testing?
With Parallel Testing, automated tests can be run in parallel or concurrently across various test environments of different device/browser/Operating System versions and their combinations. Hence, more tests are run simultaneously, reducing the execution time by many folds.
Less execution time implies less wait and fast build releases, thus reducing the required testing time!
If you are short of the hardware and plan to run the tests on Cloud-based device farms such as Saucelabs or BrowserStack, that adds another layer of complexity.
Testsigma allows you to run multiple tests in parallel on real test environments. Testsigma manages and maintains a massive device cloud to ensure that your app works fine on all browsers of different versions, even just-released versions, and also on your local devices if the local test devices of your application are not publicly accessible or if you do not wish to execute tests on cloud devices.
Why is Parallel Testing Important?
Parallel testing is significant in software development because it enables faster and more efficient application testing. By running many tests concurrently, developers can detect problems and issues in less time and with fewer resources.
Following are some of the reasons why parallel testing is performed:
- Faster test execution: Parallel testing allows several test cases to be executed simultaneously, considerably reducing testing time.
- Improved test coverage: By using parallel testing in software testing, developers may test a broader range of scenarios in less time, which can assist find flaws that would otherwise go undetected.
- Increased accuracy: Conducting tests in parallel can assist to reduce the risk of false positives or false negatives by verifying the same functionality from several perspectives.
- Scalability: Parallel testing may easily scale to meet the needs of larger projects or applications, enabling faster and more efficient testing as the project’s scope expands.
- Cost savings: Because parallel testing reduces the time and resources necessary for testing, it can assist to cut the overall cost of software development and enhance ROI.

How do you Conduct a Parallel Test Execution?
Parallel testing is important in software development because it allows for faster and more efficient testing of applications. It allows for multiple test cases to be run simultaneously, resulting in increased test coverage, improved accuracy, scalability, cost savings, and improved ROI. To conduct parallel testing, divide your test suite into smaller subsets that can be executed simultaneously. The most critical details in this text are the steps to set up a test environment with sufficient resources to:
- run multiple tests in parallel
- configure a testing framework to support parallel execution
- run the parallel tests
- monitor and analyze the results
- debug failed tests
- re-run the failed tests
- identify and fix any issues
And repeat the process until all tests have been executed successfully. This can be done manually or using a testing framework that supports parallel execution.
Creating Parallel Testing in Testsigma
In Testsigma, you can write automated tests in plain English with zero coding expertise and run them across multiple device/browser combinations you prefer.
Let’s see how Parallel Testing is performed in Testsigma.To execute automated tests in parallel, we need more than one Test Case(a specification of what is to be tested and what outcome is expected) and a Test Suite(a group of test cases).
- Test Plan Creation, Enter the Test plan Name, Description, and Prerequisite(if any), and then click on ”next”.
2. Adding Test suites to test plan, Refer to How to add/edit/delete a Test Suite in Testsigma? Here is a step-by-step representation of creating Test Suites.
3. Click on the “Machines” and “Test Suites that you want to execute Parallel Test
4. Once enabling the machines you want to run Parallel tests on, click on “Next” and check for the “Name” “lab” “OS” and other details and click on “create” in the down-right corner.
5. Once creating the test plan, click on “Run now” and execute your parallel test at ease
Parallel Test Execution in Testsigma
To create an Execution, you can navigate to the Executions page by going through the following: Test Development > Execution
- Once creating a test plan with the mentioned steps above you can now execute parallel tests
- To specify detailed execution and Recovery Settings, you can click on the + icon. You may as well ignore this.
- Go to the Executions page and click the Run Now button to execute the parallel automated tests immediately or schedule them for later.
- You can click on the Run ID under the Execution Result, and on the next page, click on the Test Case name under the Test Case Results to see a step-by-step overview of the Test Result.

Frequently Asked Questions
How will you do the parallel execution in Selenium testing?
You can use tools like TestNG or JUnit to perform parallel execution in Selenium testing. These tools include parallel execution capability and allow you to run several test cases simultaneously on various threads or machines. In the XML file for your testing framework, you can customize the parallel execution parameters, specifying the number of threads or machines for parallel execution.
What is an example of parallel testing?
Running numerous test cases concurrently on various machines or threads using a testing framework such as TestNG or JUnit is an example of parallel testing. For example, suppose you have a suite of 100 test cases. In that case, you can break them into various groups and run them in parallel on different threads or machines, reducing overall execution time dramatically.
How do you handle parallel execution in TestNG?
You must configure the parallel execution parameters in your TestNG XML file to handle parallel execution in TestNG. Set the parallel property to ‘tests’ to execute each test method in a different thread, ‘classes’ to run all test methods in a class in the same thread, or ‘instances’ to run all test methods in the same instance in a separate thread. You can also indicate how many threads will be used for parallel execution.
Can we run parallel tests without TestNG?
You can perform parallel tests without using TestNG. You can opt for other testing frameworks, such as JUnit and NUnit, or go ahead with an end-to-end testing platform like Testsigma for your parallel execution needs. Moreover, you can develop custom scripts for parallel execution using programming languages such as Java, Python, or C#.
