FShell provides a versatile testing environment for C programs which supports both interactive explorative use and a rich scripting language. More than a frontend for software model checkers, FShell is designed as a database engine which dispatches queries about the program to program analysis tools.
Such queries are expressed in FQL (FShell Query Language).
FQL specifications enable the user to formulate test specifications which range from local code-specific requirements (“cover all decisions in function `foo` using only calls from function `bar` to `foo`”) to generic code-independent requirements (e.g., “condition coverage”). We have designed FQL as a specification language which is easy to read – it is based on regular expressions – but has an expressive and precise semantics.

FShell was initially developed as part of the DFG funded project FORTAS (Formal Timing Analysis Suite for Real Time Programs) and will be further improved within the WWTF funded project “PROSEED: Proof Seeding for Software Verification”. FShell is available for download as binary for several platforms under the following licensing terms.
