Tests for Task 8: Vaccinate city

This page describes the tests for Task 8. For each task, we provide a short description of the test, information about how to recreate the test in ipython3, and the expected result.

To run the tasks for Task 8, run the following command at the Linux command-line:

$ py.test -xvk 'vaccinate_city'

Test 0

Description: No one wants to be vaccinated except the infected person. No one gets vaxxed

To run this test in ipython3 :

city = [('S', 0, 0.0),    # loc: 0
        ('S', 10, 0.0),    # loc: 1
        ('S', 0, 0.0),    # loc: 2
        ('S', 0, 0.0),    # loc: 3
        ('S', 0, 0.0),    # loc: 4
        ('I', 0, 1.0),    # loc: 5

Test 1

Description: Everyone is falling over themselves to get vaccinated. The susceptible people all get vaccinated.

To run this test in ipython3 :

Test 4

Description: Citizens with different levels of interest in getting the vaccine. Not everyone who wants the vaccine will get it.
