# Documentation

data Timeout #

Timeout to be applied to individual tests.

Since: tasty-0.8

Constructors

Timeout Integer String | `String` is the original representation of the timeout (such as `"0.5m"`), so that we can print it back. `Integer` is the number of microseconds.
NoTimeout |

after #

Arguments

:: DependencyType | whether to run the tests even if some of the dependencies fail
-> String | the pattern
-> TestTree | the subtree that depends on other tests
-> TestTree | the subtree annotated with dependency information

The `after` combinator declares dependencies between tests.

If a `TestTree` is wrapped in `after`, the tests in this tree will not run until certain other tests («dependencies») have finished. These dependencies are specified using an AWK pattern (see the «Patterns» section in the README).

Moreover, if the `DependencyType` argument is set to `AllSucceed` and at least one dependency has failed, this test tree will not run at all.

Tasty does not check that the pattern matches any tests (let alone the correct set of tests), so it is on you to supply the right pattern.

#### Examples

Expand

The following test will be executed only after all tests that contain `Foo` anywhere in their path finish.

    after AllFinish "Foo" $

testCase`"A test that depends on Foo.Bar" $ ...`

Note, however, that our test also happens to contain `Foo` as part of its name, so it also matches the pattern and becomes a dependency of itself. This will result in a `DependencyLoop` exception. To avoid this, either change the test name so that it doesn't mention `Foo` or make the pattern more specific.

You can use AWK patterns, for instance, to specify the full path to the dependency.

    after AllFinish "$0 == \"Tests.Foo.Bar\"" $

testCase`"A test that depends on Foo.Bar" $ ...`

Or only specify the dependency's own name, ignoring the group names:

    after AllFinish "$NF == \"Bar\"" $

testCase`"A test that depends on Foo.Bar" $ ...`

askOption :: IsOption v => (v -> TestTree) -> TestTree #

Customize the test tree based on the run-time options.

Since: tasty-0.6

localOption :: IsOption v => v -> TestTree -> TestTree #

Locally set the option value for the given test subtree.

Since: tasty-0.1

defaultIngredients :: [Ingredient] #

List of the default ingredients. This is what `defaultMain` uses.

At the moment it consists of `listingTests` and `consoleTestReporter`.

Since: tasty-0.4.2

mkTimeout #

Arguments

:: Integer | microseconds
-> Timeout |

A shortcut for creating `Timeout` values.

Since: tasty-0.8

data TestTree #

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`.

Since: tasty-0.1

data DependencyType #

These are the two ways in which one test may depend on the others.

This is the same distinction as the hard vs soft dependencies in TestNG.

Since: tasty-1.2

Constructors

AllSucceed | The current test tree will be executed after its dependencies finish, and only if all of the dependencies succeed.
AllFinish | The current test tree will be executed after its dependencies finish, regardless of whether they succeed or not.

type TestName = String #

The name of a test or a group of tests.

Since: tasty-0.1

testGroup :: TestName -> [TestTree] -> TestTree #

Create a named group of test cases or other groups. Tests are executed in parallel. For sequential execution, see `sequentialTestGroup`.

Since: tasty-0.1

sequentialTestGroup :: TestName -> DependencyType -> [TestTree] -> TestTree #

Create a named group of test cases or other groups. Tests are executed in order. For parallel execution, see `testGroup`.

after_ #

Arguments

:: DependencyType | whether to run the tests even if some of the dependencies fail
-> Expr | the pattern
-> TestTree | the subtree that depends on other tests
-> TestTree | the subtree annotated with dependency information

Like `after`, but accepts the pattern as a syntax tree instead of a string. Useful for generating a test tree programmatically.

#### Examples

Expand

Only match on the test's own name, ignoring the group names:

    after_ AllFinish (EQ (Field NF) (StringLit "Bar")) $

testCase`"A test that depends on Foo.Bar" $ ...`

Since: tasty-1.2

includingOptions :: [OptionDescription] -> Ingredient #

This ingredient doesn't do anything apart from registering additional options.

The option values can be accessed using `askOption`.

Since: tasty-0.6

defaultMainWithIngredients :: [Ingredient] -> TestTree -> IO () #

Parse the command line arguments and run the tests using the provided ingredient list.

When the tests finish, this function calls `exitWith` with the exit code that indicates whether any tests have failed. See `defaultMain` for details.

Since: tasty-0.4

adjustOption :: IsOption v => (v -> v) -> TestTree -> TestTree #

Locally adjust the option value for the given test subtree.

Since: tasty-0.1

withResource #

Arguments

:: IO a | initialize the resource
-> (a -> IO ()) | free the resource
-> (IO a -> TestTree) | ``IO` a` is an action which returns the acquired resource. Despite it being an `IO` action, the resource it returns will be acquired only once and shared across all the tests in the tree.
-> TestTree |

Acquire the resource to run this test (sub)tree and release it afterwards.

Since: tasty-0.5

module Test.Tasty.HUnit

Assert any Left value.

Assert any Right value.

assertParse :: (HasCallStack, Default st) => StateT st (ParsecT HledgerParseErrorData Text IO) a -> Text -> Assertion #

Assert that this stateful parser runnable in IO successfully parses all of the given input text, showing the parse error if it fails. Suitable for hledger's JournalParser parsers.

assertParseEq :: (HasCallStack, Eq a, Show a, Default st) => StateT st (ParsecT HledgerParseErrorData Text IO) a -> Text -> a -> Assertion #

Assert a parser produces an expected value.

assertParseEqOn :: (HasCallStack, Eq b, Show b, Default st) => StateT st (ParsecT HledgerParseErrorData Text IO) a -> Text -> (a -> b) -> b -> Assertion #

Like assertParseEq, but transform the parse result with the given function before comparing it.

assertParseError :: (HasCallStack, Eq a, Show a, Default st) => StateT st (ParsecT HledgerParseErrorData Text IO) a -> Text -> String -> Assertion #

Assert that this stateful parser runnable in IO fails to parse the given input text, with a parse error containing the given string.

assertParseE :: (HasCallStack, Eq a, Show a, Default st) => StateT st (ParsecT HledgerParseErrorData Text (ExceptT FinalParseError IO)) a -> Text -> Assertion #

assertParseEqE :: (Default st, Eq a, Show a, HasCallStack) => StateT st (ParsecT HledgerParseErrorData Text (ExceptT FinalParseError IO)) a -> Text -> a -> Assertion #

assertParseErrorE :: (Default st, Eq a, Show a, HasCallStack) => StateT st (ParsecT HledgerParseErrorData Text (ExceptT FinalParseError IO)) a -> Text -> String -> Assertion #

assertParseStateOn :: (HasCallStack, Eq b, Show b, Default st) => StateT st (ParsecT HledgerParseErrorData Text IO) a -> Text -> (st -> b) -> b -> Assertion #

Run a stateful parser in IO like assertParse, then assert that the final state (the wrapped state, not megaparsec's internal state), transformed by the given function, matches the given expected value.
