QTest Functionalities

Using limited hardware resources, QTest is capable of emulating from 10 to more than 50,000 users simultaneously in order to verify that an application is capable of handling real user loads and whatever the environment or client platform. You can test an application end-to-end on all the architectural layers (by applying homogeneous loads that are quantifiable and reproducible) and then use the data to identify problems that can arise before they have an impact on ultimate users.

QTest measures the response time of the principal business processes and transactions, identifying performance problems from end-to-end. It uses performance monitors in real time that capture and display performance data on all levels, servers and components. QTest allows you to look for and identify the precise source of bottlenecks at the heart of the applications architecture and generate decision-making reports. Here are the principal modules of QTest:

QTest Transaction Capture

This scenario capture module offers 3 different capture methods and therefore ensures optimal compatibility with all of your applications. It enables the capture of web transaction measurements (HTTP/HTTPS), of Web Services flows (XML or SOAP) or TCP flows (LDAP, FTP, SMTP, POP3...). In the same way, parallel flows or persistent connections (certain Java/Active X components installed on the browser use persistent connections) can be captured. The time users spend thinking is detected during the recording phase and the measurement points are automatically inserted in the script.

QTest Script Editor

This test script development module accelerates the creation and the adjustment of scripts and adapts them to a Multi-user context. QTest uses SCL Scripting language to represent queries sent from your browser. Its syntactical form is simple and easy to understand. The graphic representation (HTML rendering) of pages sent back by the server during capture or replay facilitates the mastery of the tool. In particular this representation greatly simplifies the analysis of queries. The graphic Replay allows you to check the results of the adjustment of the script. The development of the script and its modeling is also facilitated by a certain number of graphics wizards.

QTest Executer

The QTest load injection engine (load simulation) is extremely efficient and stable. It benefits from "thread pools" technology and "asynchronous I/O". The special care devoted to the design of this injection engine enables it to ensure important load levels on standard hardware. Optimal management of the memory has reduced the needs for each virtual user to 125Ko of RAM.

QTest Center

This test parameter and control terminal, designed with special care for efficiency and ergonomics, enable you to:

Define and manage a battery of load tests and/or occasional monitoring for an application and its infrastructure.
Consult and correlate in real time all the application performance indicators and application systems.
Consult, correlate and compare all the application performance indicators and application systems (analysis phase).
Create a list of anomalies using a results directory (cf. QTest Anomalies Detector module).
Create a 100% personalized report using a results directory (cf. QTest Report Designer module).

QTest Performance Monitors

System and applications performances are accessible via specific collectors adapted to different constitutive systems of your architecture. Each collector provides, thanks to tabs classified according to type, synthetic views of all the data collected. Each measurement is available independently in the form of a chart of list and can be correlated with others. A scale reducer and 12 statistical functions help process graphic results. All the data is exportable under Windows and charts can be converted to tables.

QTest Anomalies Detector

This module offers functionalities that are unique on the market. Organized around a 100% parametrizable engine, it detects possible anomalies through topological or threshold analysis by reading your test results. Three levels of severity are available and for each of them the threshold for triggering an anomaly can be set. The rule used by the engine to generate an anomaly can also be modified: 7 formulations determine the creation of an anomaly (threshold or topological analysis). The anomalies, organized by chronological order or by application component, allow you to immediately visualize their severity, the incriminated component and the period of time during which the values affected remained above the limits.

QTest Report Designer

This automatic report creation and editing tool allows you to prepare, even before the launch of a battery of tests, models of reports that you can personalize (presentation, contents). You can also automatically correlate different types of measurements, combining them on the same graph, applying statistical functions, and creating your own tables by inserting the desired measurements: all the data is available to create your own report models.
