There are moments when you'd automatically want to run a script the moment
that a file updates. Instead of running these things by hand we can use a
nifty tool called entr
to help us automate these things. You can learn
more by checking the entr project page.
We've got a python project called checking
that contains a file called web.py
.
def valid_url(url: str):
return True
We've also got a test file called called test.py
.
from checking.web import valid_url
def test_starts_correctly():
assert valid_url("http://yoyo.com")
assert valid_url("https://yoyo.com")
assert not valid_url("foobar.co")
We can run this unit test by running this command from the command line:
pytest test.py::test_starts_correctly
The goal of this series of videos will be to come up with a way to
have this line of code run automatically whenever we make a change to web.py
.
