Parallel Test Execution

As test suites grow, long execution times become a major problem. Parallel execution is a key solution.

Benefits of Running Tests in Parallel

• Execution time is significantly reduced
• CI feedback becomes faster
• Releases can happen more frequently

Tools like Playwright, Selenium Grid, and Cypress Cloud allow tests to run simultaneously across:

• Multiple browsers
• Different devices
• Various environments

Requirements for Reliable Parallel Execution

• Tests must be independent
• Shared states must be avoided
• Test data conflicts must be prevented

Otherwise, parallel runs may introduce additional failures.
