ImportError: No module named app
flask, flask-testing, python, python-import
Solution
From the comments:
There could have been two issues:
The path to `myapplication/` hadn't been added to the `$PYTHONPATH` environment variable (more info here and here) Let's say the code lives under `/home/peg/myapplication/`. You need to type in your terminal ` export PYTHONPATH=${PYTHONPATH}:/home/peg/myapplication/`
`__init__.py` could have had a typo. There shouldn't be whitespaces between the underscores __ and the init.py chunk (`__init__.py` is good, `__ init __.py` is not)
