Every business demands to ace the industry competition with top-in-class software development across their organizations. While the demand for software has expanded like never before in the recent past, it has become crucial to deliver beneficial, affordable, and competitive software while meeting the current industry and consumer demands. Software testing is a key to these. However, the traditional techniques of sequential testing are known to be time-consuming, leading to a longer time-to-market, negatively impacting the profits and ROI of a business.

2. Introducing parallel testing
Parallel testing refers to a software technique or process that
leverages automation testing capabilities to execute the
same tests simultaneously in multiple environments, real
devices, and browser configurations, which significantly
reduces the time and efforts of testing

Parallel testing in Selenium
Selenium Grid enables users to run tests in multiple environments and
browsers concurrently, assisting in performing automated cross
browser testing across several browsers There is a two-level criterion

5. The Exit level criteria
This level defines the steps for running the parallel testing
successfully, which include:
Running old systems
against the newly
developed systems
Understanding the
differences between
both systems
Going through the entire
automated browser
testing cycle while
utilizing the same input
Evaluating the output
of a newly developed
system compared to
the old system
Reporting the bugs,
if any, to the
development team

6. Execute redundant testing to ensure
that the new version of the app
performs accurately
It assists in verifying if the data format
between both versions has changed.

Benefits
As parallel testing depends on running virtual machines in the cloud, the time
invested for testing can be divided by the number of test machines.

9. Best uses for parallel testing
Certain scenarios that can be the best fit for testing uses are:
• Testing across multiple mobile devices, browsers, and networks
• Assessing versions
• Testing compatibility
• Testing localization and internationalization
• Reviewing language and validating context
• Testing environment configurations

10. Parallel testing has been identified as one of the most efficient techniques that enable
developers and testers to create a more effective CI/CD pipeline and minimize risks,
efforts, and costs.Parallelization has also been a key to cutting QA expenses and running
cases at high concurrency, and constantly improving scripts to get more accurate results.
Today's market has opened doors to plentiful parallel testing toolkits to help leverage the
benefits of this testing approach and streamline the entire SDLC.
