ErrorsΒΆ
Sometimes it’s useful to verify that a certain exception is raised. This is
achieved with assert-error
or assert-macro-error
macro. Both take two
parameters: a string and piece of code. The code is executed and resulting
exception is compared with the provided string. In case of assert-error
this comparison is done by simply calling str
for exception. For
assert-macro-error
message attribute is used. If no exception is raised,
or raised exception doesn’t match the provided string, assertion fails.

(assert-error "error"
(raise (ValueError "error"))))
(fact "macro errors can be asserted"
(assert-macro-error "cond branches need to be a list"
(cond (= 1 1) true)))
