Not sure why the coverage has dropped...?

Also I noticed that codecov reported its findings 3 hours after Travis finished, but coveralls was much faster, taking only a few minutes. Is this common or a fluke?

Not sure why the coverage has dropped...?

Expected, since typically not all branches are covered.

But no idea why it increased (slightly) on coveralls?!
I'd say we should get rid of it.

codecov reported its findings 3 hours after Travis finished

They had DB issues yesterdays, should be faster typically.

[blueyed]

Found this: lemurheavy/coveralls-public#31 - should be reported, but maybe not for Python?!
Codecov appears to still be swamped.

Oh OK, thanks.

Codecov appears to still be swamped.

I did notice in another PR today that the comment from codecov was posted right after the build finished, so it seems they are back to normal. 👍

I get we can merge this as is then?

[blueyed]

Yes!
