Open Architecture for Building and Running Load Testing. You need to quickly load test your home page, one URL within your site, or a mobile API endpoint. You can quickly create simple tests and scale them to thousands of users in a matter of minutes. Apache JMeter and WebDriver go beyond being open-source tools for cloud load testing. They are vibrant communities with deep knowledge that are built on real user needs. Open load tests allow you to write load tests in the languages and utilities that you use every day. You can create custom tests in Python or PHP. Load testing is easy, cheap, and open to everyone. This is possible thanks to an open architecture that allows tuning and control over the setting up of cloud load agents.

On request, we can offer a more specific service. We can, for example, prepare test source files and license required WAPT Pro components to be used by the client's QA team. We can also help with the analysis of test results once the test is complete. One-time testing projects can be completed in one week, while recurring arrangements can be made. We can also help you set up a client testing environment to conduct regression testing. Because each session must be unique, testing can be difficult. There is no automated testing tool that can automate the design of a website that only contains static pages. Many cases require extensive research on the client-server communication plan in order to implement the website. A good testing tool can create a detailed report that includes data and charts that show different performance parameters.

Loadster is a load test platform for websites, web apps, and APIs. Loadster can identify a site's breaking point before you users. To find bottlenecks, improve performance, or prevent crashes, create realistic test scripts.

ReadyAPI accelerates functional, security and load testing of RESTful and SOAP web services within your CI/CD pipeline. ReadyAPI allows teams create, manage, execute, and track automated functional, security and performance tests from one interface. This accelerates API quality for Agile or DevOps software teams. You can import API definitions such as OAS (Swagger), WSDLs and start testing API traffic. Or virtualizing web services to remove dependencies. Without the need to maintain scripts, create comprehensive functional API tests that are data-driven. To validate that your API can handle real traffic conditions, generate load, stress, spike, and stress tests. With each deployment, you can protect your APIs against XSS, SQL injections, malformed XML and other threats. Virtualizing RESTful SOAP, SOAP, TCP and JMS web services will remove dependencies from your testing pipeline.

With highly actionable and precise data, diagnose web UI and API performance problems. Traditional performance testing was done at the protocol layer. This leads to large tests that are difficult to read, require extensive programming, take hours or even weeks to set-up, and can be very time-consuming. Even though the results are indicative of the real world, they don't reflect the real world. It's no surprise that performance testing was difficult. LoadNinja makes it easy. Instead of testing the protocol, you can test the actual user experience across thousands of browsers with our TrueLoad technology. This will save you more than 60% of your effort. You can get the most accurate understanding of performance with minimal setup and maintenance. Without sacrificing quality, you can increase test coverage for web apps and APIs. Complex performance tests can be created without complicated correlation.
