Description

API for test providers

Synopsis

Documentation

class Typeable t => IsTest t where Source

The interface to be implemented by a test provider.

The type t is the concrete representation of the test which is used by the provider.

Methods

run Source

Arguments

:: OptionSet

options

-> t

the test to run

-> (Progress -> IO ())

a callback to report progress

-> IO Result 

Run the test

This method should cleanly catch any exceptions in the code to test, and return them as part of the Result, see FailureReason for an explanation. It is ok for run to raise an exception if there is a problem with the test suite code itself (for example, if a file that should contain example data or expected output is not found).

testOptions :: Tagged t [OptionDescription] Source

The list of options that affect execution of tests of this type

testPassed Source

Arguments

:: String

description (may be empty)

-> Result 

Result of a passed test

testFailed Source

Arguments

:: String

description

-> Result 

Result of a failed test

data Result Source

A test result

data Progress Source

Test progress information.

This may be used by a runner to provide some feedback to the user while a long-running test is executing.

Constructors

Progress 

Fields

progressText :: String

textual information about the test's progress

progressPercent :: Float

progressPercent should be a value between 0 and 1. If it's impossible to compute the estimate, use 0.

type TestName = String Source

The name of a test or a group of tests

data TestTree Source

The main data structure defining a test suite.

It consists of individual test cases and properties, organized in named groups which form a tree-like hierarchy.

There is no generic way to create a test case. Instead, every test provider (tasty-hunit, tasty-smallcheck etc.) provides a function to turn a test case into a TestTree.

Groups can be created using testGroup.

singleTest :: IsTest t => TestName -> t -> TestTree Source

Convert a test to a leaf of the TestTree
