It seems like it would be better to set up the tests to run in non-interactive, non-GUI mode, with the Agg backend.

How do you specify that? I see a bunch of backend symbols here, but what's the exact call to run in non interactive mode?

You can just do ENV["MPLBACKEND"]="agg" to use the Agg non-interactive non-GUI backend. Non-interactive mode will be the default anyway for test scripts, since julia foo.jl runs in non-interactive mode.

This is not doing what you think. Matplotlib does not allow you to switch between arbitrary GUI backends. All the pygui call is doing here is to start different event loops, it isn't actually switching Matplotlib. (For pygui to affect the Matplotlib backend, you have to run it before using PyPlot.)

I see. Shall I do the following then:

workspace()
using PyCall
pygui(:wx)
using PyPlot

for every different backend? Or shall I just remove this part because it's doing nothing?

I don't think workspace() will help; it only reinitializes Julia, not Python.

I see. I don't suppose we can really test that then? Shall I remove the parts of my test file that switch backends in another commit? What else would you like to change?

If we needed to, we could test that by launching a separate Julia process. However, I wouldn't worry about it. Having working backends is mainly Matplotlib's problem. Testing the GUI event-loop code should be something that happens in the PyCall tests.

plot(1:100,1:100)
pygui(:gtk)
plot(1:100,1:100)
pygui(:qt)
plot(1:100,1:100)

#Try another backend
workspace()
using PyCall
PyCall.pygui(:qt)
using PyPlot
plot(1:100,1:100)

#Some other internal stuff
PyPlot.svg()
PyPlot.svg(true)
PyPlot.pushclose(figure())
PyPlot.display_figs()
PyPlot.force_new_fig()
PyPlot.show()

#Final internal calls
PyPlot.monkeypatch()
PyPlot.draw_if_interactive()

PyPlot.close_queued_figs()
