check-match clj

(check-match matcher actual)

match clj

(match matcher)

Takes in a matcher and returns a checker that asserts that the provided value satisfies the matcher

match-equals clj

match but using strict equals matching behavior for maps, even nested ones.

match-roughly clj

match where all numbers match if they are within the delta of their expected value

match-with clj macro

(match-with & args)

Validates that the provided values satisfies the matcher but uses the provided type->matcher map to redefine the default matchers used for the specified types.

By default when the system sees a java.lang.Long it applies the equals matcher to it. So if, for example, we want to check that all Longs are greater than whatever Long provided in the matcher, we would do:

`(defn greater-than-matcher [expected-long] (matcher-combinators.core/->PredMatcher (fn [actual] (> actual expected-long)) (str "greater than " expected-long)))

(match-with {java.lang.Long greater-than-matcher})`

NOTE: currently doesn't work in midje provided expressions

throws-match clj

(throws-match & args)

Takes in a matcher or a matcher and throwable subclass. Returns a checker that asserts an exception was raised and the ex-data within it satisfies the matcher
