Google Web Toolkit requests


GWT (Google Web Toolkit) is the AJAX Framework developed by Google. It allows asynchronous remote procedure calls to be executed between the client and server, using GWT-RPC (Remote Procedure Call) procedure: the resulting data exchange is binary, encapsulated within the HTTP protocol.

The GWT module makes it possible to load test applications programmed with the GWT framework and using the GWT-RPC protocol.

When recording GWT-type requests, you need to load the Java classes for the objects being exchanged, as well as the client interfaces for the called services. For more information, see Google Web Toolkit.


The following diagram shows how the Google Web Toolkit module works during the recording:

The binary data exchanged between the client and server pass through the recording proxy. The Google Web Toolkit module comes into play as the data travels through the proxy, analyzing and decoding the requests. Once translated into XML, the requests are inserted in the project.


The following diagram shows how the Google Web Toolkit module works during a test run:

The XML request variables are evaluated and the module engine translates the XML to binary data. This data is then sent to the server. The binary response received is translated into XML and the validations and Variable Extractors of the played request are executed.
