Given the day-to-day needs of the larger engineering team, we can often be asked to run this test or that test. With these requests coming in, we get pulled away from getting our work done. The solution: a web application for on-demand execution of tests. We’ll look at how to build a simple Node server and front-end application to run tests, report results, and take user-inputted parameters. This flexible application can be used to automate time-consuming tasks in your products, and to execute load and performance testing on an on-demand basis. We’ll discuss best use cases and general best practices for this novel approach to testing.
