Abstract: In one embodiment, a distributed computing system includes a first worker node configured to execute a first job, a second worker node configured to execute a second job, and a master node including a processor coupled to a memory. The first job indicates a first portion of an interactive client-server application to be crawled. The second job indicates a second portion of an interactive client-server application to be crawled. The second worker node and the first worker node are configured to execute their respective jobs in parallel. The second job indicates a second portion of an interactive client-server application to be crawled. The master node is configured to assign the first job to the first worker node, assign the second job to the second worker node, and integrate the results from the first worker node and the second worker node into a record of operation of the application.

Abstract: In one embodiment, a method includes statically analyzing a validation toolkit environment. The method may also include, identifying a plurality of computational threads that do not share data structures with each other based on analysis of the validation toolkit environment. The method may additionally include calculating computational requirements of the computational threads. The method may further include distributing the threads among a plurality of resources such that the aggregate computational requirements of the computational threads are approximately evenly balanced among the plurality of resources.

Abstract: In one embodiment, a method may include accessing a particular page of Web application that includes an interactive form having at least one field for entry of data by a user of the Web application, the interactive form rendered by the Web application based on code for the interactive form. The method may also include extracting input validation code from the code, the input validation code including at least one constraint on data entered into the at least one field. The method may additionally include extracting the at least one constraint based on an analysis of the input validation code. The method may further include solving, for the at least one field, for a string value based at least on the at least one constraint for the at least one field. The may also include automatically entering, into the at least one field, the string value. The method may additionally include automatically submitting the interactive form, including the string value entered into the at least one field.
