Why automate performance testing? For more agility!
Digital transformation is driving organizations to accelerate the pace associated with the design of new services, applications or features in the name of gaining/maintaining their competitive advantages. Agile development methodologies provide a solution in this context.
Despite ongoing industry adoption of Agile and DevOps, performance testing is a highly-manual process. The goal of every performance tester is not to let it bottleneck their Agile development. The solution – integrating as much automation into the performance testing process as possible.
- Launching tests automatically within a Continuous Integration context, AND
- Automating design/maintenance tasks wherever possible
Having complete automation of your performance testing is possible when testing components. However, the human intervention of performance engineers is still necessary when performing complex tests on assembled applications.
The future of performance testing lies in the automation of tests across all stages of the application lifecycle.
How to automate performance testing with NeoLoad?
NeoLoad is the performance testing platform that makes it possible to automate test execution, test task design, update, and analysis.
During performance test design, NeoLoad automates correlation and randomization tasks, allowing you to create tests 10x faster as compared with other tools. It also enables you to import existing functional Selenium test scripts for use during performance tests.
In consideration of Continuous Integration, NeoLoad interfaces with the main CI servers: Jenkins, Bamboo, and TeamCity via tool API. At this point, all custom integrations with the different tools of the continuous deployment chain are possible.
One of the main challenges for performance engineers is updating test scenarios when the application being tested, changes. This is particularly true when testing assembled applications. NeoLoad offers an almost complete update automation functionality for scenarios created within the tool. Automation is complete for scenarios imported from Selenium.
Performance testing analysis
The most difficult phase to automate, especially for complete tests performed on an assembled application, as performance problems are due to multiple factors. Identifying their cause often requires human intervention. NeoLoad offers a wide range of performance testing analysis capabilities enabling you to accurately identify performance problem root cause and to quickly do so by isolating critical data.
It is now possible to automate a large part of the analysis in an Agile environment. NeoLoad allows you to define expected service levels (SLAs) used to assign success/failure status to a test. This allocation can be fully automated, allowing for the entire performance test cycle to be automated with a CI server. For example, an Agile team can schedule automatic, non-regression performance tests that will run during night builds. The comparison between the performance test results at the expected service level and the previous build’s test results will be carried out automatically, allowing the automatic integration process to continue if the test is successful.
