Test.HMock.Internal.Rule

Description

Internal module to define Rule, so that its constructor can be visible to other implementation code.

Synopsis

Documentation

data WholeMethodMatcher cls name m r where Source #

A way to match an entire action, using conditions that might depend on the relationship between arguments.

Constructors

JustMatcher :: Matcher cls name m r -> WholeMethodMatcher cls name m r 
SuchThat :: Matcher cls name m r -> (Action cls name m r -> Bool) -> WholeMethodMatcher cls name m r

Methods

toRule :: WholeMethodMatcher cls name m r -> Rule cls name m r Source #

showWholeMatcher :: MockableBase cls => Maybe (Action cls name m a) -> WholeMethodMatcher cls name m b -> String Source #

Displays a WholeMethodMatcher. The predicate isn't showable, but we can at least indicate whether there is one present.

data Rule (cls :: (Type -> Type) -> Constraint) (name :: Symbol) (m :: Type -> Type) (r :: Type) where Source #

A rule for matching a method and responding to it when it matches.

The method may be matched by providing either an Action to match exactly, or a Matcher. Exact matching is only available when all method arguments

A Rule may have zero or more responses, which are attached using |-> and |=>. If there are no responses for a Rule, then there must be a default response for that action, and it is used. If more than one response is added, the rule will perform the responses in order, repeating the last response if there are additional matches.

Example:

expect $
  GetLine_ anything
    |-> "hello"
    |=> (GetLine prompt) -> "The prompt was " ++ prompt
    |-> "quit"
