readFileMaybe :: FilePath -> IO (Maybe ByteString) Source #

Read the file if it exists, else return Nothing. Useful for reading golden files.

data GDiff Source #

The comparison/diff result.

Constructors

Equal	Values are equal.
DiffText	The two values are different, show a diff between the two given texts.
Fields gReason :: Maybe String gActual :: Text gExpected :: Text
ShowDiffed	The two values are different, just show the given text to the user.
Fields gReason :: Maybe String gDiff :: Text

data GShow Source #

How to show a value to the user.

Constructors

ShowText Text

Show the given text.

type GoldenResult = GoldenResult' IO Source #

type GoldenResultI = GoldenResult' Identity Source #

data GoldenResult' m Source #

Constructors

GREqual
forall a. GRDifferent a a GDiff (Maybe (a -> IO ()))
