Adding a parameter to the flask unittest

python unit-testing flask parameter-passing

I don't know your whole application however I see at least two things which could help you here:

You shouldn't use self during creating the client because this is the object of the unittest.TestCase class, not the Flask application's one. And it will be passed automatically.
```
tester = app.test_client() 
```
Your endpoint use the URL parameter, so the get request should look more or less like this:
```
tester.get(f"/add_application/{VACANCY_ID}", ...)
```
*I have used here f-string, feel free to change it if you are not using >=3.6 version of Python
