newtype AnsiTricks Source #

By default, when the option --hide-successes is given and the output goes to an ANSI-capable terminal, we employ some ANSI terminal tricks to display the name of the currently running test and then erase it if it succeeds.

These tricks sometimes fail, however—in particular, when the test names happen to be longer than the width of the terminal window. See

When that happens, this option can be used to disable the tricks. In that case, the test name will be printed only once the test fails.

Internals

The following functions and datatypes are internals that are exposed to simplify the task of rolling your own custom console reporter UI.

Output colouring

data UseColor Source #

When to use color on the output

Since: 0.11.3

Constructors

Never
Always
Auto	Only if stdout is an ANSI color supporting terminal

Instances

Eq UseColor Source #
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods (==) :: UseColor -> UseColor -> Bool # (/=) :: UseColor -> UseColor -> Bool #
Ord UseColor Source #
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods compare :: UseColor -> UseColor -> Ordering # (<) :: UseColor -> UseColor -> Bool # (<=) :: UseColor -> UseColor -> Bool # (>) :: UseColor -> UseColor -> Bool # (>=) :: UseColor -> UseColor -> Bool # max :: UseColor -> UseColor -> UseColor # min :: UseColor -> UseColor -> UseColor #
IsOption UseColor Source #	Control color output
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods defaultValue :: UseColor Source # parseValue :: String -> Maybe UseColor Source # optionName :: Tagged UseColor String Source # optionHelp :: Tagged UseColor String Source # optionCLParser :: Parser UseColor Source #

useColor :: UseColor -> Bool -> Bool Source #

useColor when isTerm decides if colors should be used, where isTerm indicates whether stdout is a terminal device.

Since: 0.11.3

Test failure statistics

data Statistics Source #

Track the number of tests that were run and failures of a TestTree or sub-tree.

Since: 0.11.3

Constructors

Statistics
Fields statTotal :: !Int Number of active tests (e.g., that match the pattern specified on the commandline), inactive tests are not counted. statFailures :: !Int Number of active tests that failed.

Instances

Semigroup Statistics Source #
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods (<>) :: Statistics -> Statistics -> Statistics # sconcat :: NonEmpty Statistics -> Statistics # stimes :: Integral b => b -> Statistics -> Statistics #
Monoid Statistics Source #
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods mempty :: Statistics # mappend :: Statistics -> Statistics -> Statistics # mconcat :: [Statistics] -> Statistics #

computeStatistics :: StatusMap -> IO Statistics Source #

computeStatistics computes a summary Statistics for a given state of the StatusMap. Useful in combination with printStatistics

printStatistics :: (?colors :: Bool) => Statistics -> Time -> IO () Source #

printStatistics reports test success/failure statistics and time it took to run. The Time results is intended to be filled in by the TestReporter callback. The colors ImplicitParam controls whether coloured output is used.

Since: 0.11.3

printStatisticsNoTime :: (?colors :: Bool) => Statistics -> IO () Source #

printStatisticsNoTime reports test success/failure statistics The colors ImplicitParam controls whether coloured output is used.

Since: 0.12

Outputting results

data TestOutput Source #

TestOutput is an intermediary between output formatting and output printing. It lets us have several different printing modes (normal; print failures only; quiet).

Since: 0.12

Constructors

PrintTest String (IO ()) (Result -> IO ())	Name of a test, an action that prints the test name, and an action that renders the result of the action.
PrintHeading String (IO ()) TestOutput	Name of a test group, an action that prints the heading of a test group and the `TestOutput` for that test group.
Skip	Inactive test (e.g. not matching the current pattern)
Seq TestOutput TestOutput	Two sets of `TestOuput` on the same level

Instances

Semigroup TestOutput Source #
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods (<>) :: TestOutput -> TestOutput -> TestOutput # sconcat :: NonEmpty TestOutput -> TestOutput # stimes :: Integral b => b -> TestOutput -> TestOutput #
Monoid TestOutput Source #
Instance details Defined in Test.Tasty.Ingredients.ConsoleReporter Methods mempty :: TestOutput # mappend :: TestOutput -> TestOutput -> TestOutput # mconcat :: [TestOutput] -> TestOutput #

buildTestOutput :: (?colors :: Bool) => OptionSet -> TestTree -> TestOutput Source #

Build the TestOutput for a TestTree and OptionSet. The colors ImplicitParam controls whether the output is colored.

Since: 0.11.3

foldTestOutput Source #

Arguments

:: Monoid b
=> (String -> IO () -> IO Result -> (Result -> IO ()) -> b)	Eliminator for test cases. The `IO ()` prints the testname. The `IO Result` blocks until the test is finished, returning it's `Result`. The `Result -> IO ()` function prints the formatted output.
-> (String -> IO () -> b -> b)	Eliminator for test groups. The `IO ()` prints the test group's name. The `b` is the result of folding the test group.
-> TestOutput	The `TestOutput` being rendered.
-> StatusMap	The `StatusMap` received by the `TestReporter`
-> b

Fold function for the TestOutput tree into a Monoid.

Since: 0.12
