Recorder acts as a proxy server between browser and the web server. It records all the interaction between browser and server to generate script file.

It records all the request and response from the client and server and generates script.

The script is corrected and parameterised as per the requirement using various options given in recorder. Many types of functions are available for parameterization, Variable Management, and Response Validation.

During this recording session itself, the RECORDER generates a detailed report for different parameters like request time, response time, number of bytes sent and number of bytes received.

In Many web application http errors are customized, so it is hard to find in runtime whether a http exception has occurred or not, using response validation with different methods we can determine whether the response is valid or not.

In SIMULATOR, the recorded script in RECORDER is used for simulating the virtual client. The number of clients and the other parameters like think time, iteration, proxy settings, cookie usage, etc., can be specified in SIMULATOR setting based on the requirement.

By executing the script, SIMULATOR hits the server with the specified number of virtual users based on the requirements.

Each virtual users will run on a separate thread and carrying its own data and other parameter simulating real user environment.

Using vuser scheduler, load can be released in ramp up and ramp down manner for specified amount of time to simulate realtime load.

The result of all virtual users are stored in separate file.

These raw data is sent to ANALYZER. SIMULATOR also sends its data to Analyzer

The ANALYZER will analyze the virtual users data and generate a detailed report.

There are many type of graph for example running virtual user or active virtual users, hit per sec, response per sec, bytes send per sec, bytes receive per sec, number of text files downloaded per sec, number of binary files downloaded per sec,.

Two important features provided by Analyzer is Detail Information By Virtual User and Detail Information By Files. These features provide very minute details like time taken to complete a request, time taken to complete a response, number of bytes send, number of bytes received, content type of response, HTTP status codes.

The report can be generated in many formats like tabular, graphical.Results can be published as HTML pages or excel pages. All the reports are stored in html pages. These reports can be exported HTML format.
