-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ -- | A test framework building on HUnit. -- -- HUnit-Plus is a testing framework for Haskell that builds on the HUnit -- test framework. HUnit-Plus provides functions and operators for -- creating assertions and tests similar to those provided by the HUnit -- framework. Unlike HUnit, HUnit-Plus uses the same data structures as -- cabal's Distribution.TestSuite framework, allowing full -- compatibility with cabal's testing facilities. -- -- HUnit-Plus also provides expanded reporting capabilities, including -- the ability to generate JUnit-style XML reports, along with a very -- flexible mechanism for selecting which tests to be executed. Lastly, -- HUnit-Plus provides a wrapper which generates standalone -- test-execution programs from a set of test suites. -- -- This is release candidate 2 for 1.0 (1.0-RC2) @package HUnit-Plus @version 0.3.1 -- | This module handles the complexities of writing information to the -- terminal, including modifying text in place. This code is imported -- from the original HUnit library. module Test.HUnitPlus.Terminal -- | Simplifies the input string by interpreting \r and -- \b characters specially so that the result string has the -- same final (or terminal, pun intended) appearance as would the -- input string when written to a terminal that overwrites character -- positions following carriage returns and backspaces. terminalAppearance :: String -> String -- | Sets HUnit-Plus tests can be specified using Filters. These are -- used by Test.HUnitPlus.Execution and Test.HUnitPlus.Main -- to select which tests are run. Filters can specify tests belonging to -- a certain suite, starting with a certain path, having a certain tag, -- or combinations thereof. -- -- Filters are optimized for the behavior of programs created by the -- createMain function, which runs a test if it matches -- any of the filters specified. There is also a string format for -- filters, which is how filters are specified in testlist files and -- command-line arguments. The format is optimized for simplicity, and as -- such, it is not necessarily possible to describe a given Filter -- with a single textual representation of a filter. -- -- The format for filters is as follows: -- -- [suite][path][tags] -- -- Where at least one of the suite, path, or tags -- elements are present -- -- The suite element is a comma-separated list of suite names -- (alphanumeric, no spaces), enclosed in brackets ('[' ']'). -- -- The path element is a series of path elements (alphanumeric, no -- spaces), separated by dots (.). -- -- The tags element consists of a \@ character, followed -- by a comma-separated list of tag names (alphanumeric, no spaces). -- -- The following are examples of textual filters, and their meanings: -- -- -- -- The most common use case of filters is to select a single failing test -- to run, as part of fixing it. In this case, a single filter consisting -- of the path to the test will have this effect. module Test.HUnitPlus.Filter -- | A tree-like structure that represents a set of tests within a given -- suite. data Selector Selector :: Map String Selector -> !(Maybe (Set String)) -> Selector -- | Selectors for subgroups of this one.
