Do we need to compare that pixels are equivalent, if instead we can compare the html outputs? The advantages/benefits is that: - This is real integration test that executes/renders the notebook outputs; - This can find errors and problems that regex/plain-text comparison could not catch; - This rules out false test failures (flakiness) in regex/plain-text comparison tests. - The test result is screenshot that is highly readable. - You don't even need to write any test. Just give the infrastructure a notebook and you are done. It does have its own disadvantage/flakiness: - Anything that causes unstable rendering will potentially fail the test. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
