"When I've completed developing the back end for a website, I test its performance to ensure it will function as it was designed and provide an exceptional user experience. Some of the best practices I employ during this testing phase include:
-Testing each of the software units independently and as a unit
-Establishing baseline measurements to track changes after addressing issues
-Testing early and in each phase of development to identify potential issues
-Conducting multiple tests to ensure the results are consistent
-Performing tests in environments as close to the production systems as possible
-Calculating averages and eliminating outliers to identify actionable items"
