midje.parsing.arrow-symbols — midje 1.10.5

Lexicon of all Midje arrows. Arrows are used in both the sweet and expanded forms.

=> clj

As a checking arrow: the left side should result in the right side. As a prerequisite arrow: the fake should return the thing on the right.

=contains=> clj

Data prerequisite arrow. Ex. (fact (:a ..m..) => 1 (provided ..m.. =contains=> {:a 1}))

=deny=> clj

Checking arrow. The left side should NOT result in the right side.

=expands-to=> clj

Checking arrow. The left side should macroexpand-1 to the right side.

=future=> clj

Checking arrow. The check won't evaluate, but will leave a 'WORK TO DO' reminder in the report.

=not=> clj

Checking arrow. The left side should NOT result in the right side.

=streams=> clj

Prerequisite arrow. The fake will return the first element of the given sequence the first time the fake is evaluated, the second element the second time, and so on. Note, that each element is only evaluated when needed, thus in the below example the exception is never thrown.

Ex. (def tally [] (+ (bar) (bar) (bar))) (fact (tally) => 6 (provided (bar) =streams=> [1 2 3 (throw (Exception.))]))

=test=> clj

Use this when testing Midje code that processes arrow-forms

=throw-parse-exception=> clj

Use this to generate an exception while parsing

=throws=> clj

Prerequisite arrow. The fake will throw the Throwable on the right side of the arrow.

Ex. (def f [] (g)) (fact (f) => (throws IllegalArgumentException. "boom") (provided (g) =throws=> (IllegalArgumentException. "boom")))
