@Evizero Looks like there are a lot of test failures. Any idea what's going on?

[Evizero]

is it working locally? looks to me like some fileio incompat

[DilumAluthge]

The tests also fail for me locally.

Do you know what versions of FileIO, AstroIO, etc. the tests are compatible with?

[Evizero]

I am afraid not. I would appreciate the help here

The issue is with the ReferenceTests package. You have reference tests in .txt files, but when ReferenceTests tries to load them with FileIO, it interprets the file as being something other than text.

Probably this needs some fixes upstream in ReferenceTests and/or FileIO.

Text should actually be the default assumption for ReferenceTests — see JuliaTesting/ReferenceTests.jl#27 (/cc @christopher-dG, @oxinabox).

Also, JuliaTesting/ReferenceTests.jl#19 and JuliaTesting/ReferenceTests.jl#73 could potentially be related as well (/cc @juliohm, @johnnychen94).

Looks like the tests are broken a long time ago. I'm fully scheduled this April but I can take an investigation in May. @Evizero It would be quite convenient if you can send me an invitation.
