Why Performance Testing Is Important

Performance testing is important to prepare your application for normal activity as well as special events. Doing performance testing helps you evaluate the speed, stability, and scalability of an application.


But to do performance testing well, you need the right tools — like BlazeMeter.

Why Do Performance Testing With BlazeMeter?

You should do performance testing with BlazeMeter to ensure testing is effective and easy.


BlazeMeter is a SaaS-based performance testing tool, fully compatible with JMeter and many other open source load testing tools. Whether you are running automated tests every night as part of your continuous integration workflow or load testing before a special event like Black Friday, BlazeMeter has the features for your business.

Here are seven reasons why.

1. Easy to Run Performance Tests

BlazeMeter is easy to use, even for beginners. Simply upload your script, easily configure your test in the intuitive GUI, and run.

BlazeMeter requires no installation.  Better yet, you do not need to configure JMeter or any other tool on the test engines, nor do you need to edit your test files or properties files in order to run your test on a global scale. That means you’ll have more time and resources for running your tests.

BlazeMeter simplifies and improves script maintenance. Tired of managing long and complex test scripts? BlazeMeter’s Multi-Test breaks a large test run down into smaller components for analysis so you can easily focus on specific features and use cases, resulting in smaller pieces of code per commit. Meanwhile, BlazeMeter’s continuous analysis keeps you abreast of your test’s performance.


2. Full Open Source Compatibility

Open-source performance testing have many unique advantages, such as access to a reservoir of technical experts from all over the world. BlazeMeter not only lets you keep enjoying all these open-source advantages, but leverages them. Get everything from open source, plus SaaS, advanced analytics, collaboration, and more. How?

BlazeMeter is fully compatible with the latest versions of many open source testing tools, such as JMeter, Gatling, Selenium, and Taurus. Simply choose your favorite tool, upload your script, then run it. You can also easily override your script’s configuration using BlazeMeter’s GUI. 

For example, if you upload a JMeter script, you can override its properties, concurrency, duration, and ramp-up.  You can even alter what geographic locations it executes from. Once your test runs, you can analyze the results via various insightful reports, which you can then share with your colleagues.


3. Scale High, Scale Global

BlazeMeter runs in the cloud, so you don’t have to rely on your own machine’s resources when scaling the number of virtual users. You can easily ramp up to thousands or tens of thousands of virtual users to simulate how your system will perform under heavy usage and surprising traffic spikes.

Website and app traffic doesn’t come from just one location. In BlazeMeter, you can choose to simulate traffic from over fifty geo-locations all over the world. You decide how to divide up the traffic between them, then analyze the test results for each location.


4. CI and APM Integrations

We know performance testing is a (very important) part of your Continuous Integration workflow, so BlazeMeter integrates with many CI tools. BlazeMeter features specialized plugins for Jenkins,  TeamCity, Bamboo, AWS CodePipeline, and Azure DevOps Pipeline, and can integrate with additional tools via advanced Taurus and API options. You can schedule and run your tests from the command line as part of your larger workflow and with every commit.

BlazeMeter’s APM integration options allow you to leverage your own performance monitoring solution as well.  Seamlessly integrate with DX APM, New Relic, AppDynamics, Dynatrace, AWS IAM, or CloudWatch.

5. Online Support

Need help with your BlazeMeter tests? Our superstar support team can assist with any issues you encounter with our platform. We also have experts ready to assist you with your testing through service engagements. What makes them so good? They are deeply involved with our R&D, open source testing communities, and the tens of thousands of scripts in their arsenal.

If you run into any issues with your testing, BlazeMeter’s experts have you covered. End to End.

6. Share Your Load Tests and Results with Managers

BlazeMeter’s Workspaces and Projects enable collaboration and asset sharing within securely defined boundaries.  Add users and assign managers to oversee performance tests and manage user privileges. Since BlazeMeter is easy to use, inexperienced users require very little training to start working on existing projects and managers can easily track who is working on what.

Export performance results as an executive summary, a high-level, printable report geared for managers and non-technical stakeholders that shows bottom lines, graphs, and a glossary.  This report helps prioritize scrum sprints by emphasizing the system’s performance status and the importance of performance testing systems.

7. Insightful Reporting That is Easy to Read

BlazeMeter reports are clear, comprehensive, and insightful. Your test’s report will appear just a few minutes after execution begins, then will continue updating until the test completes. Analyze performance KPIs including throughput, error rate, response time, and various others metrics, then drill down further to see how your system performs by location, test case, specific request label, and more. Active subscribers can even access these reports months after the tests ran, then overlay reports from different time periods to identify interesting trends.

BlazeMeter’s colorful tables and graphs make analytics accessible to everyone, so that each developer, engineer, and DevOps professional can clearly understand where to improve their code and system. 

That's why performance testing is better with BlazeMeter.

By the way, BlazeMeter’s capabilities are hardly limited to performance testing. BlazeMeter can expand your testing arsenal to include functional tests (including GUI, API, and scriptless tests), API monitoring, and even mock services that can simulate your application without actually using it.
