Tests de charge de logiciel

The application is stressed/set under load. Many simultaneous/synchronized actions test the application's load limit. QF‑Test's special characteristic is that load tests are executed via the graphical interface (User/transaction via QF-Test in their own user sessions) and not evitably protocol based.
The detection of non functional errors is possible: e.g. response time, simulated live operation, stability of server/client environment. Supplement to functional oriented tests.
You can create load tests out of functional components (QF-Test is primarly a functional GUI testing tool), so you can reuse existing steps.
Checking the client's side hardware dimensions is possible. Alternatives: via virtual computers/desktops, cloud based solutions, dockers/ containers.
QF-Test can be combined with many other tools, so that load is generated: Tools like JMeter, JUnit as well as specialized load test tools like NeoLoad (a protocol based tool for web), Loadrunner from hp, Gatling, Silkperformer, Scapa TPP etc.
Technical details and implementation of QF-Test load tests are documented in the manual. An easy scenario and example of implementation is delivered in the QF-Test installation.
For the execution of load tests (also for higher numbers) cost-effective runtime licenses can be purchased or leased (subscription licensing) for a determined period of time.

Practical examples: QF-Test in use

Mrs Weiß of Münchener Verein, Munich, Germany: „When the cost-benefit-analysis in a project doesn't recommend an extensive load tests, the existing QF-Test automted tests are started manually or time-controlled as a batch-job on 20 virtual machines at MÜNCHENER VEREIN insurance group. So that load is created on the application and a statement concerning performance is possible."

NeoLoad and QF‑Test:
Tool combination for Web load tests

QF-Test's focus is the web interface, NeoLoad's focus are the Backend systems and network level.

Regression tests created via QF-Test can still be used in NeoLoad as load tests, stress tests and performance tests.
In the web area such tests are executed on network protocol level, this means without graphical presentation in the browser. NeoLoad by Neotys converts these QF-Test regression tests into web load tests.
Muth Partners has creaetd a special software interface to integrate existing QF-Test scripts.

Advantages of load tests with both tools

These NeoLoad load tests contain a a metric of end user experience for new analysis possibilities.
Automated import from QF-Test to NeoLoad to a great extend.
Recognition possible via names of sequences and transactions
