Parallel testing is a strategy of running multiple automated test scripts simultaneously against various configurations to deliver high-quality products without slowing down the speed of delivery. It provides several benefits, including a significant reduction in time it takes to fully test an application, increased test coverage, and faster results. However, implementing parallel testing comes with its own set of challenges, such as limitations of infrastructure, data dependencies, and refactoring test scripts to ensure proper test data management. To overcome these challenges, organizations can consider outsourcing the responsibility of maintaining a testing grid, using cloud-based testing grids, and refactoring test scripts to be independent of each other. By analyzing parallel testing strategies and considering potential pitfalls, organizations can further their adoption of parallelization within their testing model.
