Test.Tasty.Ingredients.ConsoleReporter

Description

Console reporter ingredient.

Since: 0.11.3

Synopsis

Documentation

consoleTestReporter :: Ingredient Source #

A simple console UI.

Since: 0.4

consoleTestReporterWithHook :: ([TestName] -> Result -> IO Result) -> Ingredient Source #

A simple console UI with a hook to postprocess results, depending on their names and external conditions (e. g., its previous outcome, stored in a file). Names are listed in reverse order: from test's own name to a name of the outermost test group.

Since: 1.4.2

newtype Quiet Source #

Do not print test results (see README for details).

Since: 0.8

Constructors

Quiet Bool 

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.

Since: 1.3

Fields

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

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.

computeStatistics :: StatusMap -> IO Statistics Source #

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

Since: 1.2.3

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

Printing a test.

Fields

  • String

    Name of the test.

  • (IO ())

    Action that prints the test name.

  • (Progress -> IO ())

    Action that prints the progress of the test. Since: 1.5

  • (Result -> IO ())

    Action that renders the result of the test.

PrintHeading

Printing a test group.

Fields

Skip

Inactive test (e.g. not matching the current pattern).

Seq TestOutput TestOutput

Two sets of TestOutput on the same level.

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

withConsoleFormat :: (?colors :: Bool) => ConsoleFormatPrinter Source #

Run action with console configured for a specific output format

This function does not apply any output formats if colors are disabled at command line or console detection.

Can be used by providers that wish to provider specific result details printing, while re-using the tasty formats and coloring logic.

Since: 1.3.1
