In order to test all the features of nbconvert you need to have pandoc and
TexLive installed.
In your environment pip install nbconvert[all] will be needed to be able to
run all of the tests and to test all of the features.
If you only want to run some of the tests run pip install nbconvert[test].
If you are going to release a version of nbconvert you should also be capable
of testing it. Please follow the instructions in Testing.
