Glossary
Simulates a real user navigation. It is basically a succession of web pages.
It may contain logical actions such as containers, loops and delays for a more complex behaviour.
A population is a set of Virtual Users. It allows
testing
your site with
different business behaviours. A typical use is to test a commercial site with 90% of users that browse the
product catalog while 10% are doing a full purchase transaction.
Describes all the settings of a load test: the duration, the load policy (ramp-up, constant, peak),
the number of Virtual Users to generate,...
NeoLoad handles multiple scenarios in a project.
Program that plays the scenario by simulating the desired number of users.
A new program is launched for each test and exits when the test has finished.
That ensures that the program is in a clean state before any test.
The Load Generator Agent listens for NeoLoad Controller request to start/stop the load generator for each load test.
An agent is embedded in the NeoLoad Controller for user convenience.
Separate Load Generator Agent can be installed on remote Load Generator computers.
Time to wait before playing a web page, simulating the time spent by the real user to read
the previous page before clicking the link to the current one.
When running a test, a global think time can be defined for all pages (use Variables for random values in a range), or
the test can use the Think Time defined on each page.
Variables allow adding dynamic content to the scenario. A typical use is to set variables as parameter values
when submitting an HTML Form, or to set username/password on login.
The different kind of variables are counters, list, random integer, random String, Date,...
Represents a web page as displayed in a Browser. It is composed of an HTML page and its sub components such as images or css files.
This is the physical HTTP request to the server to retrieve an HTML page, an image or a CSS file.
Classic proxy server to be used to connect to the server.
The NeoLoad recorder used to record a scenario. It is seen as a Proxy by the browser.
This recording proxy can use the user proxy if needed.
The standard deviation shows the response time variation against the average response time.
When the value is high, the response time is very fluctuating.
When the value is low, the response time is very constant and steady.
The average 90 percent is computed from the average response time after removing the 5% minimum values and 5% maximum values.
The aberrant points are ignored. The result is near of what most of end-users get as response time.
The number of milliseconds that have passed before the first byte of the response was received.
Assertion for validation. Allows validating the server response during the test. Validation can be based on the response content, size or duration.
