Usually, no mechanisms were in place until the software reached a test environment or even the production stage. Having these measurements is a drastic change from old practices, where often there was no way to measure the performance of an application and its components. As soon as developers write code, the team should have performance measurements, which should continue until production. It helps to have application performance measurements at every moment in the software development process. Those actions help trigger, detect, and measure performance issues, even at the development stage, and make it easier to identify and report any problem, even before you check in any code. Modern practices suggest implementing rules for what developers deliver. One possibility is implementing telemetry, instrumentation, unit tests, and timers inside the application code and storing the performance measurements. And the cost of fixing defects that make it into production is much higher than if you catch them earlier. The old mindset made it difficult to identify defects generated in the code and allowed those defects to reach and at times pass QA, acceptance, and performance tests and go into production.
SOMOVE SOFTWARE CODE
Your developers are your first line of defenseĬontrary to the old ways of thinking about the software lifecycle and QA practices, where developers were disconnected from QA efforts related to the code they created, your developers must be wholly involved in QA and performance assurance from the beginning.
With this performance focus, your teams-including your developers-will have performance etiquette in mind before, during, and after creating software. Teams must define measurements such as response time on a single thread, concurrent response, the number of database connections/reads, maximum bandwidth consumed, and so on. Everything you implement around performance should define metrics that must pass before you mark anything as done. Think early about performance, including not only infrastructure, but also all performance implications from the requirements gathering stage to building epics, features, and tasks. If rework is needed or the team must release faulty software into production, there will be a significant impact. This practice weakens performance assurance, leaving little time for corrections and resulting in massive costs when problems are detected. Old strategies focus on automation and front-end load tests until the very last steps in the software development lifecycle, which limits the time available to complete the usual load testing. Some of those tasks create mechanisms in the environments, including pipelines, monitoring, and instrumentation. The best processes to assure good performance require tasks to be executed even before writing the first line of code. The traditional approach to performance testing doesn't address performance assurance, which implies all the possible tasks you may need to perform to ensure the best performance. Load tests have their place, but first you need to perform other tasks, described below. Performance testing encompasses myriad practices and actions that must be taken as a whole. But they should be one of the last steps you execute and, in some situations, you shouldn't even do them at all. Today, load testing and load automations are just some of the actions you need to exercise in your performance testing practice. Even performance testing professionals often switch these up, which perpetuates the bad old tradition of testing performance by running only load automations and load tests. This practice has caused performance testing and load testing to be wrongly seen as interchangeable terms.
Modern performance testing goes beyond load testingĬreating load automation, executing load scenarios, and testing a system's performance by slamming it with load have been what organizations typically do when they have to embrace performance testing. Here are tips that will help your team implement modern performance testing practices-and drop outdated processes that drag down your results. But it's not just developers who are struggling to keep up with constantly changing software: This evolution is forcing test engineers to modernize their performance testing practices-and to let go of old methodologies that can't keep up.
The world of application development keeps evolving at breakneck speed with respect to processes, delivery, and methodologies.
