It tests the quality of an app such as speed, stability, and scalability. Without it, users may encounter poor usability. Here, we break down what automated performance testing is, why you should shift it left, and how to do it.Table of ContentsWhat Is Automated Performance Testing?What Are the Types of Performance Testing?Website Performance TestingMobile App Performance TestingWhy Shift Performance Testing Left?Do Automated Performance Testing With Perfecto & BlazeMeterTable of Contents1 - What Is Automated Performance Testing?2 - What Are the Types of Performance Testing?3 - Website Performance Testing4 - Mobile App Performance Testing5 - Why Shift Performance Testing Left?6 - Do Automated Performance Testing With Perfecto & BlazeMeterBack to topWhat Is Automated Performance Testing?Automated performance testing checks the speed, response time, reliability, resource usage, and scalability of software under an expected workload by leveraging automation.The goal of performance testing is to eliminate performance bottlenecks in the software.Back to topWhat Are the Types of Performance Testing?Leveraging automated performance testing can help you check speed, scalability, stability, and reliability faster. That’s why it’s time to shift performance testing left. Here are several types of performance testing:Load TestingLoad testing tests the performance by increasing the load until it reaches a threshold.Stress TestingStress testing tests the performance and stability when hardware resources aren’t sufficient. Common types of stress tests include soak testing and spike testing. Endurance TestingMeasures how an app performs over an extended period of time.Scalability TestingMeasures an app’s performance at handling an increased workload.Spike TestingMeasures how an app performs with sudden jumps in workload.Volume TestingMeasures an app’s performance with large amounts of data.Performance tests should be tested like your users are using the service. The art of building the right test coverage metrics is key. Your testing strategy should include recommendations on when to test.You need to know which types of platforms and operating systems need to be tested, no matter where you are in the globe. This ensures that your coverage is aligned and the user experience is optimized for performance.One thing that can help with this is referencing a test coverage index.

These factors need to be tested across devices and OS versions in order to provide the best end-user experience on mobile apps.Back to topWhy Shift Performance Testing Left?It’s so important to shift testing left and include all types of testing in a single pipeline. This includes performance testing. By shifting performance testing left, you’ll identify potential performance bottleneck issues fast so you can move faster in today's digital reality.Here’s why this is important.In Waterfall development, performance testing typically happens just before deployment. But if development and functional testing take longer than expected, there’s less time for performance testing. (And this happens often.) So, you might discover performance problems too late. Performance issues can be tricky to resolve, too. If issues are related to code or architecture, you don’t have time to react.Moving to Agile and shifting performance testing left helps you resolve these issues earlier in the development cycle, when you actually have time to fix them.Example: Microservices ArchitectureFor example, a microservices architecture is made up of small components. One of the advantages is that when you have major loads or peaks, you don’t have to redeploy the entire stack anymore. You can just deploy more nodes.But this can create performance issues. If your application is consuming resources heavily, you’ll keep spinning up more nodes. You’ll have delivered acceptable response times or user experience. But the cost of the infrastructure has increased significantly.You can use performance testing to simulate this scenario before it happens.To get performance testing right, you need to:Understand how your user is interacting with your environment and your application.Run tests.Draw conclusions based on user experience.Make the right changes in the code.Back to topDo Automated Performance Testing With Perfecto & BlazeMeterAutomated performance testing is easier with Perfecto and BlazeMeter. With both of these testing platforms under the Perforce umbrella, Perfecto and BlazeMeter work together to offer performance testing that is fully comprehensive. For example, BlazeMeter Performance testing can be used in conjunction with your mobile tests for UX testing.Using both of these tools in conjunction, you can simulate realistic mobile traffic patterns to test both your mobile user experience and your backend under load in the cloud. Plus, you can scale up to two million virtual users. See for yourself how you can leverage Perfecto and BlazeMeter for automated performance testing today.
