verbose mode

[dpinol]

Hi,
ideally I'd like st like
assert_that(a, verbose=True).is_less_than(b)
So that, when a<b the assertion succeeds, but logs what this the value of a, and ideally also the value of b.
Or maybe it's already possible to accomplish this?

thanks

There's no built-in pass logging today: a passing assertion does no bookkeeping, which is what keeps it cheap
Outside soft_assertions() an assertion only returns if it held, so the simplest route for now is to log right after it:

assert_that(a).is_less_than(b)
log.info("a=%r < b=%r", a, b)

With a plain assert and a matcher, pytest's own pytest_assertion_pass hook (opt-in via enable_assertion_pass_hook = true) already reports 3 == a value less than <5> on a pass I guess

Where would you want passing checks to show up (console or log output, a log file, a report such as Allure), and what is it for (debugging values, seeing how close a value came to a threshold, keeping evidence of what was checked) ?

Would switching it on for a block of code or a whole session work for you, or do you need it per assertion?

console is ok

and what is it for (debugging values, seeing how close a value came to a threshold, keeping evidence of what was checked) ?

seeing how close a value came to a threshold & keeping evidence of what was checked. To avoid the burden of manually writing a log.info

For a block would be fine

thanks!
