Implementing a custom Formatter

A formatter is a set of actions. Each action is evaluated when a certain situation is encountered during a test run.

Actions live in the FormatM monad. It provides access to the runner state and primitives for appending to the generated report.

data Formatter Source #

Constructors

Formatter

Fields

headerFormatter :: FormatM ()
exampleGroupStarted :: [ String ] -> String -> FormatM ()

evaluated before each test group
exampleGroupDone :: FormatM ()

evaluated after each test group
exampleStarted :: Path -> FormatM ()

evaluated before each example
exampleProgress :: Path -> Progress -> FormatM ()

used to notify the progress of the currently evaluated example
exampleSucceeded :: Path -> String -> FormatM ()

evaluated after each successful example
exampleFailed :: Path -> String -> FailureReason -> FormatM ()

evaluated after each failed example
examplePending :: Path -> String -> Maybe String -> FormatM ()

evaluated after each pending example
failedFormatter :: FormatM ()

evaluated after a test run
footerFormatter :: FormatM ()

evaluated after failedFormatter

data FailureReason Source #

Constructors

NoReason
Reason String
ExpectedButGot ( Maybe String ) String String
Error ( Maybe String ) SomeException

getCPUTime :: FormatM ( Maybe Seconds ) Source #

Get the used CPU time since the test run has been started.

getRealTime :: FormatM Seconds Source #

Get the passed real time since the test run has been started.

Appending to the generated report

write :: String -> FormatM () Source #

Append some output to the report.

writeLine :: String -> FormatM () Source #

The same as write , but adds a newline character.

writeTransient :: String -> FormatM () Source #

Dealing with colors

withInfoColor :: FormatM a -> FormatM a Source #

Set output color to cyan, run given action, and finally restore the default color.

withSuccessColor :: FormatM a -> FormatM a Source #

Set output color to green, run given action, and finally restore the default color.

withPendingColor :: FormatM a -> FormatM a Source #

Set output color to yellow, run given action, and finally restore the default color.

withFailColor :: FormatM a -> FormatM a Source #

Set output color to red, run given action, and finally restore the default color.

useDiff :: FormatM Bool Source #

Return True if the user requested colorized diffs, False otherwise.

extraChunk :: String -> FormatM () Source #

Output given chunk in red.

missingChunk :: String -> FormatM () Source #

Output given chunk in green.

Helpers

formatException :: SomeException -> String Source #

The function formatException converts an exception to a string.

This is different from show . The type of the exception is included, e.g.:

>>> formatException (toException DivideByZero)
"ArithException\ndivide by zero"

For IOException s the IOErrorType is included, as well.
