# Set up
2+
3+
We'll need a few things to install for this section:
4+
5+
- https://sites.google.com/a/chromium.org/chromedriver/downloads
6+
- behave (http://pythonhosted.org/behave/)
7+
- selenium (http://selenium-python.readthedocs.io/installation.html)
8+
9+
10+
## Running the tests
11+
12+
To run the tests, you'll need to do this in a terminal (but remember to have the Flask app running!):
13+
14+
```bash
15+
source venv/bin/activate
16+
cd section6/video_code/
17+
python -m behave tests/acceptance
18+
```
19+
20+
If you want to run the tests in PyCharm, you'll need to create appropriate configurations.
21+
22+
Create a Python configuration for the app.
23+
