The goal of maintaining a fast-paced development cycle while ensuring quality is achieved by using proven testing strategies such as parallel testing, shift-left testing, and automated testing. Parallel testing involves running multiple tests simultaneously to save time, while shift-left testing shifts the testing process to the left in the delivery cycle to begin testing earlier in the development process. Automated testing enables continuous testing with each build, ensuring major components of the application are bug-free before deployment. These strategies can be tied into a continuous delivery strategy, providing an up-to-date and functional test environment at all times.
