KeyError: 'TEST' during running pytest

MongoDB University M220P: MongoDB for Python Developers
#1

Hi,

Really need some help for running pytest here.
Environment:
MacOS, Python 3.7 with Anaconda

I didn’t change the SECRET_KEY during init setup of the environment, and at the start the pytest was able to run (during Unit 1 for pytest -m connection). Then recently I realize it should be changed. But after change the .ini SECRET_KEY value, I’ve been running into this key error, and change it back to original value don’t solve the problem. Basically all the test met this error.

def __getitem__(self, key):
    if key != self.default_section and not self.has_section(key):

      raise KeyError(key)

E KeyError: ‘TEST’

Really appreciate if someone can provide some suggestion.
Thanks in advance.

Hi @XUZHENG_03440,

Please check the indentation of .ini file. If you cannot solve it, please share the contents of the .ini file here.

Hi Kanika:

Thank you very much for the suggestion. I try to replace the .ini with original one from handout, even before change the mongo url, it has met the same error.

My .ini is as below (url is changed, “#” is double quoted to avoid it show as headline format).

(mflix) linxz-MAC:m220py linxz$ vi .ini

“# Ticket: Connection”
“# Rename this file to .ini after filling in your MFLIX_DB_URI and your SECRET_KEY”
“# Do not surround the URI with quotes”

[PROD]
SECRET_KEY = super_secret_key_you_should_change
MFLIX_DB_URI = mongodb+srv://“my atlas instance url”
MFLIX_NS = sample_mflix

[TEST]
SECRET_KEY = super_secret_testing_key
MFLIX_DB_URI = mongodb+srv://“my atlas instance url”
MFLIX_NS = sample_mflix

Try after removing double quotes.

Hi Kanika:

It’s just for replacement. In the file there is no double quotes. It doesn’t work.

mongodb+srv://m220student:m220password@mflix-xxxx.gcp.mongodb.net

And for more information. After python run.py, I can get the correct key from website. So just the pytest is not working in my case.

Thanks.

Hi @XUZHENG_03440,

From which directory are you running the tests?

It seems like you are running the tests from mflix-python/tests directory. So, it is not able to read .ini file at all.
Please move back one directory and run the tests from mflix-python directory.

Hi Kanika:

Thanks a lot for pointing that out. I didn’t realize pytest need to read the .ini file.

Yes my ‘pytest -m connection’ runs ok on the mflix-python directory.

Thank you very much.
