Futhark.Test

Description

Facilities for reading Futhark test programs. A Futhark test program is an ordinary Futhark program where an initial comment block specifies input- and output-sets.

Synopsis

Documentation

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

Read the test specification from the given Futhark program.

testSpecFromFileOrDie :: FilePath -> IO ProgramTest Source #

Like testSpecFromFile, but kills the process on error.

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

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)] Source #

Like testSpecsFromPaths, but kills the process on errors.

valuesFromByteString :: String -> ByteString -> Either String [Value] Source #

Try to parse a several values from a byte string. The String parameter is used for error messages.

newtype FutharkExe Source #

The futhark executable we are using. This is merely a wrapper around the underlying file path, because we will be using a lot of different file paths here, and it is easy to mix them up.

getValues :: (MonadFail m, MonadIO m) => FutharkExe -> FilePath -> Values -> m [Value] Source #

Get the actual core Futhark values corresponding to a Values specification. The first FilePath is the path of the futhark executable, and the second is the directory which file paths are read relative to.

getValuesBS :: MonadIO m => FutharkExe -> FilePath -> Values -> m ByteString Source #

Extract a pretty representation of some Values. In the IO monad because this might involve reading from a file. There is no guarantee that the resulting byte string yields a readable value.

withValuesFile :: MonadIO m => FutharkExe -> FilePath -> Values -> (FilePath -> IO a) -> m a Source #

Evaluate an IO action while the values are available in the binary format in a file by some name. The file will be removed after the action is done.

checkValueTypes :: (MonadError Text m, MonadIO m) => FilePath -> [TypeName] -> m () Source #

Check that the file contains values of the expected types.

compareValues :: [Value] -> [Value] -> [Mismatch] Source #

Compare two sets of Futhark values for equality. Shapes and types must also match.

checkResult :: (MonadError Text m, MonadIO m) => FilePath -> [Value] -> [Value] -> m () Source #

Check that the result is as expected, and write files and throw an error if not.

testRunReferenceOutput :: FilePath -> Text -> TestRun -> FilePath Source #

When/if generating a reference output file for this run, what should it be called? Includes the "data/" folder.

getExpectedResult :: (MonadFail m, MonadIO m) => FutharkExe -> FilePath -> Text -> TestRun -> m (ExpectedResult [Value]) Source #

Get the values corresponding to an expected result, if any.

compileProgram :: (MonadIO m, MonadError [Text] m) => [String] -> FutharkExe -> String -> FilePath -> m (ByteString, ByteString) Source #

compileProgram extra_options futhark backend program compiles program with the command futhark backend extra-options..., and returns stdout and stderr of the compiler. Throws an IO exception containing stderr if compilation fails.

runProgram :: FutharkExe -> FilePath -> [String] -> String -> Text -> Values -> IO (ExitCode, ByteString, ByteString) Source #

runProgram futhark runner extra_options prog entry input runs the Futhark program prog (which must have the .fut suffix), executing the entry entry point and providing input on stdin. The program must have been compiled in advance with compileProgram. If runner is non-null, then it is used as "interpreter" for the compiled program (e.g. python when using the Python backends). The extra_options are passed to the program.

readResults :: (MonadIO m, MonadError Text m) => Server -> [VarName] -> FilePath -> m [Value] Source #

Read the given variables from a running server.

ensureReferenceOutput :: (MonadIO m, MonadError [Text] m) => Maybe Int -> FutharkExe -> String -> FilePath -> [InputOutputs] -> m () Source #

Ensure that any reference output files exist, or create them (by compiling the program with the reference compiler and running it on the input) if necessary.

determineTuning :: MonadIO m => Maybe FilePath -> FilePath -> m ([String], String) Source #

Determine the --tuning options to pass to the program. The first argument is the extension of the tuning file, or Nothing if none should be used.

binaryName :: FilePath -> FilePath Source #

The name we use for compiled programs.

data Mismatch Source #

Two values differ in some way. The Show instance produces a human-readable explanation.
