裂片等待element.visible

Question

I have some anoying behaviour with splinter. I do

button.click()
assert not button.visible  # Fails

Then I do

button.click()
time.sleep(1)
assert not button.visible  # Succeeds

That is pretty bad... Is this intended behaviour? Everything else seems to poll and wait for a bit before it fails.

I am not sure how Splinter works internally, but looks like you are using an attribute access and it might be cached. Have you tried:

 assert not browser.is_element_visible_by_css("#my-button-id")

is_element_visible_by_css has always an implicit wait you can configure in Splinter settings. Please note that with browser (Selenium) testing everything has implicit waits, as browser DOM operations happen asynchronously and there is no backchannel to get information when some element becomes visible or when it disappears.
