creates a ‘satisfies’ checker if not already a checker

((->checker 1) 1) => true

((->checker (exactly 1)) 1) => true

a checker that returns true for any value

(anything nil) => true

(anything :hello :world) => true

checker that allows approximate verifications

((approx 1) 1.000001) => true

((approx 1) 1.1) => false

((approx 1 0.0000001) 1.001) => false

adds a form to capture test input

creates a ‘code.test.checker.common.Checker’ object

(checker {:tag :anything :fn (fn x true)}) => code.test.checker.common.Checker

checks to see if a datastructure is a ‘code.test.checker.common.Checker’

(checker? (checker {:tag :anything :fn (fn x true)})) => true

checker that allows exact verifications

((exactly 1) 1) => true

((exactly Long) 1) => false

((exactly number?) 1) => false

returns the string representation of a function

(function-string every?) => “every?”

(function-string reset!) => “reset!”

checker that allows loose verifications

((satisfies 1) 1) => true

((satisfies Long) 1) => true

((satisfies number?) 1) => true

((satisfies #{1 2 3}) 1) => true

((satisfies 1 2 3) 1) => false

((satisfies number?) “e”) => false

((satisfies #“hello”) #“hello”) => true

a checker that looks into a ref object

((stores 1) (volatile! 1)) => true

((stores 1) 1) => false

determines if the results of a check have succeeded

(-> (satisfies Long) (verify 1) succeeded?) => true

(-> (satisfies even?) (verify 1) succeeded?) => false

checker that determines if an exception has been thrown

((throws Exception “Hello There”) (res/result {:status :exception :data (Exception. “Hello There”)})) => true

verifies a value with it’s associated check

(verify (satisfies 2) 1) => (contains-in {:status :success :data false :checker {:tag :satisfies :doc string? :expect 2} :actual 1 :from :verify})

(verify (->checker #(/ % 0)) 1) => (contains {:status :exception :data java.lang.ArithmeticException :from :verify})
