# The README's "How each claim is tested" table names, for each security claim,
|
|
# a test in client-go as `file_test.go`: `TestOrFuzzName`. A row is only worth
|
|
# something while that function exists: a renamed or deleted test would leave
|
|
# the claim looking covered when nothing checks it. This finds every such
|
|
# citation in the table and confirms `func <name>(` is defined in the cited
|
|
# file. It prints ok or MISSING for each row and exits non-zero if any is
|
|
# missing.
|
|
#
|
|
# A table it can only partly read must not pass as a clean one, so the rows
|
|
# are read one by one: every body row's test cell must be either exactly one
|
|
# citation in that form or "not covered by a test". A row that is neither is
|
|
# named and fails the check, and so does a table with no citations at all.
|
|
#
|
|
# It checks that the test exists, not what it asserts; that part is reviewed
|
|
# by reading the test when a row is added or changed.
