A method and system for automatic use case generation. A computer system receives a configuration file that defines multiple categories and one or more filters. Each of the categories includes one or more options and each of the filters defines a condition for combining the options across the categories. The computer system builds a data hierarchy based on the configuration file. The data hierarchy includes a root and multiple levels. Each of the levels corresponds to one of the categories and includes nodes that represent the options of the corresponding categories. The computer system parses the data hierarchy from the root, while skipping the nodes and their descendants that do not satisfy the filters, to identify combinations of the options across the categories that satisfy the filters. The computer system then generates use cases that use the identified combinations as settings.

Generating valid use cases from a parsed configuration file describing use case options

A method and a system automatically install a guest operating system on a virtual machine run by a host. In one embodiment, the host includes an installation manager that computes a checksum of a region of an input request image. The installation manager compares the checksum with a stored checksum, and, based on a comparison result of the checksum, automatically determines an input to the input request.
