### Setting up an environment for manual testing

The automated tests are run with browser's all network requests going through a Python proxy. The proxy allows us to mock websites that are then navigated to in the browser. At times you might want to replicate this test environment while playing manually with the browser. A poor man's approach is to add something like:

``` python

from time import sleep

sleep(100000)

```

inside one of the test functions and then run that test function from Pytest (with `MOZ_HEADLESS` unset!). This might make sense when debugging some particular test case. For general experiments we have instead provided convenience targets `make test-environment` and `make test-environment-with-haketilo`. Running any of those will spawn a browser window *together* with a Python shell where `driver` variable will hold Selenium driver object controlling that browser. In case of the `test-environment-with-haketilo` target the browser will additionally appear with Haketilo loaded into it.
