specsim/master + astropy/2.0.9 + pytest/5.0.1 = massive failures

[sbailey]

There is some incompatibility in the testing infrastructure with the combination specsim/master + astropy/2.0.9 + pytest/5.0.1, with many errors of the form listed below. Downgrading to pytest/3.6.2 works. i.e. the problem is with the testing infrastructure / configuration, not with the specsim code itself.

I see that there are several astropy-infrastructure pull requests open on specsim; it is possible that merging those would already fix this.

Note that astropy 2 is only compatible with pytest < 3.7.

I don't think this ticket is relevant any longer.
