Futhark.Test.Spec

Definition and parsing of a test specification.

Documentation

testSpecFromProgram :: FilePath -> IO (Either String ProgramTest)

Read the test specification from the given Futhark program.

testSpecFromProgramOrDie :: FilePath -> IO ProgramTest

Like testSpecFromProgram, but exits the process on error.

testSpecsFromPaths :: [FilePath] -> IO (Either String [(FilePath, ProgramTest)])

Read test specifications from the given paths, which can be a files or directories containing .fut files and further directories.

testSpecsFromPathsOrDie :: [FilePath] -> IO [(FilePath, ProgramTest)]

Like testSpecsFromPaths, but kills the process on errors.

testSpecFromFile :: FilePath -> IO (Either String ProgramTest)

Read a test specification from a file. Expects only a single block, and no comment prefixes.

testSpecFromFileOrDie :: FilePath -> IO ProgramTest

Like testSpecFromFile, but kills the process on errors.
