Integration testing is a crucial phase in the software development pipeline where teams run checks against smaller components to ensure they work together seamlessly. To increase release velocity with CI/CD practices, it's essential to identify issues early on and roll back fixes before they propagate throughout the product lifecycle. When scaling integration testing volume, developers should prioritize well-testing their components, optimize for test parallelization, and consider infrastructure options that meet their specific requirements. A comprehensive test platform can support various testing needs, including full cross-browser coverage, headless browsers, and debugging tools, to help teams scale with their continuous testing pipeline.
