So it looks like everything is working great.
0:02
We just run pytest against our _all_tests.py file here
0:05
and everything is super.
0:07
Let's just see how this might go
0:08
if we, say, weren't inside a PyCharm.
0:11
So let's go over to the directory here
0:13
and make sure we activate the virtual environment
0:16
so everything's going to work that's of course required.
0:19
But now I should be able to type pytest _all_tests.py
0:23
and let's just disable the warnings
0:24
there's some lower level libraries we can't fix
0:27
that are issuing some warnings
0:28
so just let's see what's going on.
0:30
This should work just the same as
0:32
if I go over here and press this, right?
0:36
No. No module named pypi.org.
0:39
So we have a couple of options.
0:40
One, we could actually convert our website
0:43
into a package, and then install it
0:45
and that problem just goes away.
0:47
The other thing is, we can just add
0:49
a little line of code here to fix this.
0:51
So why does it run here, and not there
0:53
when basically the same command is entered?
0:55
It's because if you look at the run configuration
0:58
the content routes and source routes
1:01
are added to the Python path.
1:03
Namely, this folder up here is added
1:06
to the Python path, so pypi.org
1:08
and test and so on, exist and can be imported.
1:12
Well, that's actually pretty easy to do.
1:15
You had to do it earlier
1:16
but I tried to avoid talking about it before, right here.
1:19
So this is really all we have to do
1:21
is we add this little block of code that says
1:24
go and find out what the containing folder is
1:27
and then add it at the front of the Python path.
1:31
So if we go over here to our all models
1:32
and we put this at the top, like so
1:35
it doesn't quite look as nice
1:37
it makes us get a little grunt in here
1:38
but you know what?
1:39
Now, if we try this again, beautiful.
1:43
It's working great.
1:44
And of course it's sill going to work
1:46
inside PyCharm, just like that.
1:48
So it's a little bit frustrating the way
1:51
that wasn't working before
1:52
but as you can see we could either
1:54
make this a package and then install it for development
1:57
which is not a big deal but a little complicated
1:59
or we just put this one line here
2:01
so there's no action other than running this file necessary.
2:05
There's probably other options
2:06
I'm sure there are other options
2:07
but here's two that'll work pretty well.
