Description

This module defines the detailed test suite interface which makes it possible to expose individual tests to Cabal or other test agents.

Synopsis

- data TestInstance = TestInstance {
  - run :: IO Progress
  - name :: String
  - tags :: [String]
  - options :: [OptionDescr]
  - setOption :: String -> String -> Either String TestInstance
  }
- data OptionDescr = OptionDescr {
  - optionName :: String
  - optionDescription :: String
  - optionType :: OptionType
  - optionDefault :: Maybe String
  }
- data OptionType
  - = OptionFile {
    - optionFileMustExist :: Bool
    - optionFileIsDir :: Bool
    - optionFileExtensions :: [String]
    }
  - | OptionString {
    - optionStringMultiline :: Bool
    }
  - | OptionNumber {
    - optionNumberIsInt :: Bool
    - optionNumberBounds :: (Maybe String, Maybe String)

data TestInstance Source #

Constructors

TestInstance |

Fields

- run :: IO Progress

  Perform the test.

- name :: String

  A name for the test, unique within a test suite.

- tags :: [String]

  Users can select groups of tests by their tags.

- options :: [OptionDescr]

  Descriptions of the options recognized by this test.

- setOption :: String -> String -> Either String TestInstance

  Try to set the named option to the given value. Returns an error message if the option is not supported or the value could not be correctly parsed; otherwise, a `TestInstance` with the option set to the given value is returned.

data OptionDescr Source #

Constructors

OptionDescr |

Fields

- optionName :: String
- optionDescription :: String

  A human-readable description of the option to guide the user setting it.

- optionType :: OptionType
- optionDefault :: Maybe String

Constructors

Group |

Fields

- groupName :: String
- concurrently :: Bool

  If true, then children of this group may be run in parallel. Note that this setting is not inherited by children. In particular, consider a group F with "concurrently = False" that has some children, including a group T with "concurrently = True". The children of group T may be run concurrently with each other, as long as none are run at the same time as any of the direct children of group F.
