FShell is a white-box test input generator for ANSI C programs. It uses a model checking backend which employs the CBMC framework to solve FQL queries. Using iterative constraint strengthening, a form of incremental SAT solving, we efficiently enumerate a series of test cases.

Using FShell

After launching FShell (use `fshell –help` to get a list of command line options), an interactive shell is presented to the user. This shell accepts queries and commands as described on the FQL page.
