How the Team at 500px Moves Faster with Semaphore

500px, a customer of Semaphore since 2014, has integrated automated testing into their development workflow to facilitate rapid deployment of new code, enhancing user value by minimizing the time spent on testing. By transitioning from Jenkins to Semaphore, 500px has developed a scalable continuous integration process, allowing them to automatically run approximately 4,000 tests in parallel on each code change, ensuring new features work as expected without disrupting existing functionality. This approach not only accelerates the testing process but also encourages the development of independent tests, which are executed randomly to avoid dependency on execution order. Semaphore's integration with Slack further aids developers by notifying them of test outcomes, enabling quick identification and resolution of issues, thereby supporting 500px's need for speed and reliability in deploying updates.
