Performance testing features

Performance Testing Features

Performance Test Recording: QEngine performance testing tool provides an easy to use browser-based recording to capture HTTP/HTTPS requests including AJAX requests.
Flexible User Scenarios: To emulate the load test of real-user activities, an easy, complete and customizable building of user scenarios are provided.
Real-world Performance Testing: Real-world web load testing allows you to dynamically vary the number of virtual users hitting your web applications/web sites to study the load testing/stress testing conditions under varying load.
Dynamic Data Replacement: Modifying the performance test scripts to reflect dynamic data requires no programming skills.
Session Handling: Support for standard session handling techniques, such as cookies and URL-rewriting. Option to load test your web applications with Dynamic Session ID, by storing session from previous response.
Support for cookies, basic authentication, URL re-directing/SSL: Automatically handles basic HTTP/HTTPS features such as, cookies, BASIC authentication for password-protected sites and URL redirects.
Parameterized Performance Tests: Parameterize URL Get/Post data or session data at runtime from cookies, previous response, previous url, by executing a Javascript or hidden elements.
Datapools for Parameterization: To use unique data for each user in load testing/stress testing, QEngine allows creation of datapools (values from an external datasource such as Database or FLAT file).
Configurable Think Time: Configurable think times to perform real-world performance testing where each user spends thinking time (wait time) before performing the next action in the web page.
Browser Simulation: Support for simulating exact browser behavior (MSIE, Firefox and Mozilla simulation).
Random Delay: Random Delay for Virtual user start to simulate user visit to the web site/web application in irregular intervals.
Bandwidth Simulation: Option to emulate different network speeds during playback.
IP Spoofing: IP Spoofing support to simulate unique IP address for each user in web application load testing.
Server Performance Monitors: Load test your web sites/web applications with integrated monitoring of server machine's system resources (cpu % and memory usage).
Database Monitors: Load test your web sites/web applications with integrated monitoring of databases such as MySQL or Oracle to collect the database parameters.
Configurable Playback Options: Wide range of play options that affects the playback of load test scripts.
Compressed server response (gzip, deflate): QEngine performance testing provides the ability to test web servers that use compressed server response (gzip, deflate).
Quick Host Change: Option to run against different hosts without re-recording the web load test scripts.
Proxy Support: Peformance testing can be done through proxy servers, supporting authentication and proxy exclusions for local networks.
Distributed Load Testing: Option to simulate thousands of simultaneous users working from a single machine or distributed on multiple machines. Centralized coordination and reporting of distributed load testing results.
Batch Testing: Provision to execute performance test suites from batch files or using scheduling utilities.
Response Validation: Extensive built-in functions for response validation. Response Validation report shows the success and failures to make sure you get right response while performing the web load testing.
Export Reports: Provision to export reports to Excel for further processing of your load test results.
Comprehensive Reports: Load test reports summarizes the key results such as response time, throughput, hits, number of users simulated, error percentage, etc to identify potential bottlenecks.
