Possible flaky test in backup-restore test suite
Context: Build failure at https://gitlab.com/charts/gitlab/-/jobs/106221269
Test that checks if images uploads to issue is loaded correctly is possibly flaky. This is because, we are testing whether the address defined by
src attribute of the image is returning 200. But, on checking the source code of the issue, we see this (split to multiple lines for readability)
<div class="wiki"> <p dir="auto"> <a class="no-attachment-icon" href="/root/testproject1/uploads/90701344e9ebb53fa9ebac83d43afdcc/Screen_Shot_2018-05-01_at_2.53.34_PM.png" target="_blank" rel="noopener noreferrer"> <img src="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" alt="Screen_Shot_2018-05-01_at_2.53.34_PM" class="lazy" data-src="/root/testproject1/uploads/90701344e9ebb53fa9ebac83d43afdcc/Screen_Shot_2018-05-01_at_2.53.34_PM.png"> </a> </p> </div>
The image has
lazy class, which means it is being lazy loaded. So,
src is not pointing to the actual image, but
data-src is. Once the image is loaded,
src gets replaced by
data-src. So, if the test checks for
src, before the lazy loading is done, it gets the wrong data.
Check if file mentioned in
data-src (instead of
src) is available and returns 200.
