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.

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.

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" $ ...

Since: tasty-1.2

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

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

assertLeft :: (HasCallStack, Eq b, Show b) => Either a b -> Assertion Source #

Assert any Left value.

assertRight :: (HasCallStack, Eq a, Show a) => Either a b -> Assertion Source #

Assert any Right value.

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

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 Source #

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 Source #

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 Source #

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 Source #

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

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

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

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.
