XLT provides best-practice reports out of the box, based on decades of load and performance testing experience.

Load Test Reports

XLT performance reports provide a complete picture and include key metrics like runtime totals, averages, and percentiles, along with service-level agreement (SLA) data, configuration details, and a comprehensive list of errors. Data is available at all levels, from individual transactions and actions to requests. See a simple example of a scaling test for an echo service.

Comparison Reports

Uncertain whether your recent changes improved performance? XLT's comparison reports provide the clear data you need to confidently assess the impact of each test run. See a simple example of two echo service test runs (one with http, the other with https).

Trend Reports

XLT trend reports provide a visual history of your application's performance. Color-coded charts clearly illustrate how performance has evolved across numerous test runs, making it easy to identify trends and potential issues.

Because every environment is unique, XLT offers a wide range of extensions and modifications to ensure a perfect fit.

Reports

XLT provides full control over report customization. Because we include the CSS and render templates, you can easily adjust the content and layout to perfectly match your needs. Create custom summaries, reduce data, or design entirely new report formats.

Custom and External Data

Log more detailed information about your system under test with XLT's custom values, timers, and extended logging. XLT reports can include data from external files, providing a comprehensive view even when real-time access is unavailable.

Use Java

Need something XLT doesn't offer out-of-the-box? Use Java to customize and extend its capabilities.

You can utilize an large number of machines for load testing. Scale up across datacenters easily. XLT orchestrates the load distribution, uploads, and downloads on its own.

XLT uses differential and concurrent up- and downloads for maximum speed. The load is automatically distributed across all agents.

By the way, you can later split the report by location, if needed.

XLT supports a flexible setup of load profiles ranging from steady user rates to arrival rates. Compose long-running test setups to reflect what happens during a day, absolutely freely configurable.

Do you need to have a test where, after a slow ramp-up of low traffic, the load jumps within a minute to peak traffic, stays on that level for 10 minutes to then come back in waves? Well, XLT lets you do so. No limits.

XLT reports are easily sharable with anyone. They are not connected to XLT anymore after they have been created.

All reports are plain HTML. So you can zip them up, mail them, upload them, attach them, and share them with whatever system you prefer.

Did you know that you can start your load test from one machine, and collect the results from another? Or maybe your co-worker can collect the data later and analyze it for you, while you're already on your way to a meeting.

The result browser is your tool to visually check loaded data and debug problems.

During script development, the result browser shows you all details about your recently executed script, so you can make sure that you covered everything and that the requests match the real traffic.

When errors occur during load testing, the last moments of the transaction are saved, including the downloaded data and all technical details. You can see what was sent and received.

A test is only as good as its verifications. XLT supports and encourages as much validation as possible to really make sure that the transferred data matches the expectations.

You can use the full syntax of assertions known from JUnit. If you like Hamcrest, include it. XLT also provides access to all sub-requests of a page, so you can run even more detailed validations.

XLT is made to be integrated into all kinds of automation processes. No matter if it‘s just a shell script or a full build process.

We built XLT in a way that perfectly gets along with your preferred IDE, the command line, build processes, or just with a little bit of shell scripting.

To match the behavior with your testing needs, lots of parameters can be adjusted. Set timeouts, keep-alive, compression, image loading, permitted hosts, thinktimes, error handling, and much more.

XLT offers a richt set of options to modify the behavior so that all kinds of different configurations can be tested. Most of them can even be set for each scenario individually.

XLT uses open formats for results and reports. Perfectly suited for storing them anywhere. Result data and HTML reports are separated so you can easily make a decision if you want to store a lot of data or just the final outcome.

Reports and results store your full test configuration. Repeating the exact same run days or weeks later is easy.
