type test = string * test_case list

A test is an US-ASCII encoded name and a list of test cases.

exception Test_error

The exception return by run in case of errors.

val run : ?and_exit:bool -> string -> test list -> unit

run n t runs the test suite t. n is is the name of the tested library. The optional argument and_exit controls what happens when the function ends. By default, and_exit is set, which makes the function exit with 0 if everything is fine or 1 if there is an issue. If and_exit then the function raises Test_error on error.
