Common interface between HUnit and QuickCheck

class IsProp prop where Source #

IsProp is a common interface for HUnit and QuickCheck tests. It abstracts uses of Assertion and Property for (IsProp prop) => prop, then provide instances for both HU.Asserton and QC.Property.

Minimal complete definition

testCounterexample, testConjoin, testDisjoin

Methods

testCounterexample :: String -> prop -> prop Source #

Displays the string to the user in case of failure

testConjoin :: [prop] -> prop Source #

Conjunction of a number of results

testDisjoin :: [prop] -> prop Source #

Disjunction of a number of results

testFailure :: prop Source #

Flags a failure

testSuccess :: prop Source #

Flags a success

testFailureMsg :: String -> prop Source #

Flags a failure with a message

testBool :: IsProp prop => Bool -> prop Source #

testAll :: IsProp prop => (a -> prop) -> [a] -> prop Source #

(.==.) :: (IsProp prop, Eq a) => a -> a -> prop infix 4 Source #

(.&&.) :: IsProp prop => prop -> prop -> prop infixr 3 Source #

(.||.) :: IsProp prop => prop -> prop -> prop infixr 2 Source #

assertionToMaybe :: Assertion -> IO (Maybe HUnitFailure) Source #

Catches a HUnit test failure, if the test fails.

forAll :: Show a => Gen a -> (a -> Property) -> Property Source #

Here we provide our own universsal quantifier instead of forAll, so we can monomorphize it to returning a Property

Extra HUnit assertions

assertSubset :: (Show a, Eq a) => [a] -> [a] -> Assertion Source #

Asserts whether a set is a subset of another one, both given as lists.

assertSameSets :: (Show a, Eq a) => [a] -> [a] -> Assertion Source #

Asserts whether 2 sets are equal, both given as lists.

Testing mockchain traces

data Test a prop Source #

Data structure to test a mockchain trace

Constructors

Test

Fields

testTrace :: StagedMockChain a
The mockchain trace to test
testInitDist :: InitialDistribution
The initial distribution from which the trace should be run
testErrorProp :: PrettyCookedOpts -> MockChainError -> [MockChainLogEntry] -> prop
The property should hold in case of failure
testResultProp :: PrettyCookedOpts -> a -> UtxoState -> [MockChainLogEntry] -> prop
The property that should hold in case of success
testPrettyOpts :: PrettyCookedOpts
The printing option that should be use to render test results

mustSucceedTest :: IsProp prop => StagedMockChain a -> Test a prop Source #

A test template which expects a success from a trace

mustFailTest :: (IsProp prop, Show a) => StagedMockChain a -> Test a prop Source #

A test template which expects a failure from a trace

emptyTest :: IsProp prop => StagedMockChain a -> Test a prop Source #

A test template with no particular requirement on the trace

withInitDist :: IsProp prop => Test a prop -> InitialDistribution -> Test a prop Source #

Appending an initial distribution to a test

withPrettyOpts :: IsProp prop => Test a prop -> PrettyCookedOpts -> Test a prop Source #

Appending printing options to a test

withJournalPred :: IsProp prop => Test a prop -> ([MockChainLogEntry] -> prop) -> Test a prop Source #

Appending a predicate over the log to a test. This will be used both in case of success or failure of the trace.

withValueAndStatePred :: IsProp prop => Test a prop -> (a -> UtxoState -> prop) -> Test a prop Source #

Appending a predicate over the return value and state, which will be used in case of success of the trace.

withValuePred :: IsProp prop => Test a prop -> (a -> prop) -> Test a prop Source #

Appending a predicate over the return value, which will be used in case of success of the trace.

withStatePred :: IsProp prop => Test a prop -> (UtxoState -> prop) -> Test a prop Source #

Appending a predicate over the return state, which will be used in case of success of the trace.

withPrettyAndErrorPred :: IsProp prop => Test a prop -> (PrettyCookedOpts -> MockChainError -> prop) -> Test a prop Source #

Appending a predicate over an error which uses the printing options, which will be used in case of failure of the trace.

withErrorPred :: IsProp prop => Test a prop -> (MockChainError -> prop) -> Test a prop Source #

testToProp :: IsProp prop => Test a prop -> prop Source #

This takes a test and transforms it into an actual test case in prop.

Ensure that all results produced by the staged mockchain succeed, starting from the default initial distribution

testFails :: (IsProp prop, Show a) => StagedMockChain a -> prop Source #

Ensure that all results produced by the staged mockchain fail

isPhase1Failure :: IsProp prop => PrettyCookedOpts -> MockChainError -> prop Source #

A property to ensure a phase 1 failure

testFailsInPhase1 :: (IsProp prop, Show a) => StagedMockChain a -> prop Source #

A test that succeeds when the trace results in a phase 1 failure

A property to ensure a phase 2 failure

testFailsInPhase2 :: (IsProp prop, Show a) => StagedMockChain a -> prop Source #

A test that succeeds when the trace results in a phase 2 failure

isPhase1FailureWithMsg :: IsProp prop => (String -> Bool) -> PrettyCookedOpts -> MockChainError -> prop Source #

Same as isPhase1Failure with an added predicate on the text error

testFailsInPhase1WithMsg :: (IsProp prop, Show a) => (String -> Bool) -> StagedMockChain a -> prop Source #

Same as testFailsInPhase1 with an added predicate on the text error

isPhase2FailureWithMsg :: IsProp prop => (String -> Bool) -> PrettyCookedOpts -> MockChainError -> prop Source #

Same as isPhase2Failure with an added predicate over the text error

testFailsInPhase2WithMsg :: (IsProp prop, Show a) => (String -> Bool) -> StagedMockChain a -> prop Source #
