Travis is so much fun...

If you are skipping widgets and plugins, what are you exactly testing here?

Sorry, I don't get it :-)

@blink1073, could you explain what's the purpose of this PR? It's not that clear to me :-)

[blink1073]

A lot of the modules have assert statements in them when run as __main__, this was a start at at least making sure those were still valid. I ran in to trouble with QApplication errors with widgets and plugins, so I skipped those for now.

@blink1073 are the errors by any chance qtawesome related??

[blink1073]

For instance, widgets/arraybuilder brings up a dialog that would need to be closed.

+ python spyderlib/plugins/__init__.py
QPixmap: Must construct a QApplication before a QPaintDevice

+ python spyderlib/qt/QtCore.py
Traceback (most recent call last):
  File "spyderlib/qt/QtCore.py", line 9, in <module>
    if os.environ['QT_API'] == 'pyqt5':
  File "/Users/ssilvester/anaconda/lib/python3.4/os.py", line 633, in __getitem__
    raise KeyError(key) from None
KeyError: 'QT_API'

Thanks @blink1073 for the clarification. This is really important work because with it we can also start testing widgets and plugins, by using @goanpeca's trick of setting a timer to close a QApplication after a certain time! :-)

Thanks a lot for it!!

There are errors detected by Travis after this PR, but I'll fix them on the other PR I'm working on :-)
