Subject: [PATCH v2 1/4] kunit: tool: Do not error on tests without test plans
Date: Tue, 26 Oct 2021 18:36:59 -0700 [thread overview]
Message-ID: <20211027013702.2039566-1-davidgow@google.com> (raw)
The (K)TAP spec encourages test output to begin with a 'test plan': a
count of the number of tests being run of the form:
1..n
However, some test suites might not know the number of subtests in
advance (for example, KUnit's parameterised tests use a generator
function). In this case, it's not possible to print the test plan in
advance.
kunit_tool already parses test output which doesn't contain a plan, but
reports an error. Since we want to use nested subtests with KUnit
paramterised tests, remove this error.
