Hmm looking at the test again, I see this:

    assert "Markers: table" in exp.plugin_table.choices
    exp.filename = str(tmp_path / "cubeviz_export.ecsv")
    exp.plugin_table = "Markers: table"
    exp.export()

But the test creates Markers_table.ecsv in the source directory (where I ran pytest). Is there a bigger bug, @kecnry ?

Thanks!

exp.filename might need to be changed to exp.filename_value after #2824

ValueError: filename_value is not a valid attribute and cannot be set

[kecnry]

ok, then this must be the user API, in which case exp.filename.value
