<br>
I'm trying to get a nice feedback loop for coverage testing both a Python REST<br>
server and the client side GUI program. I thought I could get coverage to<br>
produce an html report on some interval -- say every 5-10 seconds. This<br>
doesn't seem to be a documented use-case ... or is it?<br>
<br>
Following the documentation, I've inserted:<br>
<br>
import coverage<br>
cov = coverage.Coverage()<br>
cov.start()<br>
sys.coverer = cov # stash this in a global place<br>
my_program() # bunch of code<br>
cov.stop()<br>
cov.save()<br>
cov.html_report()<br>
<br>
Inside my_program (which is really a whole GUI event loop), I've kicked off a<br>
little chunk periodically to update the html:<br>
<br>
sys.coverer.save()<br>
sys.coverer.html_report()<br>
# attempt at hacking some result-caching by coverage<br>
sys.coverer._measured = True<br>
<br>
On the first time I come to my update-the-html code and I get an htmlcov<br>
directory that looks correct. On the second and subsequent times, it looks as<br>
though it rewrites exactly the same html.<br>
<br>
Is this possible? Is there other caching I need to defeat? There is file hash<br>
checking code in the HtmlReport which I do not fully understand.<br>
<br>
I understand this might be slow. I was hoping that I could get an up-to-date<br>
CoverageData object quickly then go htmlify it in the background. That looks<br>
difficult since the HtmlReport takes a Coverage object not a CoverageData.<br>
<br>
Thanks,<br>
