;;; Commentary:
|
|
|
|
;; * Use `testcover-start' to instrument a Lisp file for coverage testing.
|
|
;; * Use `testcover-mark-all' to add overlay "splotches" to the Lisp file's
|
|
;; buffer to show where coverage is lacking. Normally, a red splotch
|
|
;; indicates the form was never evaluated; a brown splotch means it always
|
|
;; evaluated to the same value.
|
|
;; * Use `testcover-next-mark' (bind it to a key!) to jump to the next spot
|
|
;; that has a splotch.
|
|
|
|
;; * Basic algorithm: use `edebug' to mark up the function text with
|
|
;; instrumentation callbacks, then replace edebug's callbacks with ours.
|
|
;; * To show good coverage, we want to see two values for every form, except
|
|
;; functions that always return the same value and `defconst' variables
|
|
;; need show only one value for good coverage. To avoid the brown
|
|
;; splotch, the definitions for constants and 1-valued functions must
|
|
;; precede the references.
|
|
;; * Use the macro `1value' in your Lisp code to mark spots where the local
|
|
;; code environment causes a function or variable to always have the same
|
|
;; value, but the function or variable is not intrinsically 1-valued.
|
|
;; * Use the macro `noreturn' in your Lisp code to mark function calls that
|
|
;; never return, because of the local code environment, even though the
|
|
;; function being called is capable of returning in other cases.
|
|
|
|
;; Problems:
|
|
;; * To detect different values, we store the form's result in a vector and
|
|
;; compare the next result using `equal'. We don't copy the form's
|
|
;; result, so if caller alters it (`setcar', etc.) we'll think the next
|
|
;; call has the same value! Also, equal thinks two strings are the same
|
|
;; if they differ only in properties.
|
|
;; * Because we have only a "1value" class and no "always nil" class, we have
|
|
;; to treat as potentially 1-valued any `and' whose last term is 1-valued,
|
|
;; in case the last term is always nil. Example:
|
|
;; (and (< (point) 1000) (forward-char 10))
|
|
;; This form always returns nil. Similarly, `or', `if', and `cond' are
|
|
;; treated as potentially 1-valued if all clauses are, in case those
|
|
;; values are always nil. Unlike truly 1-valued functions, it is not an
|
|
;; error if these "potentially" 1-valued forms actually return differing
|
|
;; values.
