Create virtualenv:

$ virtualenv .env

Activate virtualenv:

$ source .env/bin/activate

2. Install Python Libraries

Python testing frameworks

unittest

Introduction: http://pythontesting.net/framework/unittest/unittest-introduction/

Documentation: http://docs.python.org/2/library/unittest.html

Assertions methods: https://docs.python.org/2/library/unittest.html#unittest.TestCase

Execute examples:

$ python -m unittest discover test

PyTest

Introduction: http://pythontesting.net/framework/pytest/pytest-introduction/

Execute examples:

$ pytest -s test

Note that pytest auto-detects also unittest-based test cases.

Selenium

Introduction: https://selenium-python.readthedocs.io/getting-started.html

Documentation: https://seleniumhq.github.io/selenium/docs/api/py/api.html

1. Start demoapp

$ python demoapp/server.py

Open http://localhost:7272/

Try to login with username demo and password mode and with invalid credentials.

2. Run sample test

$ cd selenium && python test_login.py

Take a look at screeenshots in selenium/reports folder.

3. Create automated test cases for valid and invalid login

    def test_valid_login(self):
        """TODO: valid login scenario"""
        pass

    def test_invalid_login(self):
        """TODO: invalid login scenario"""
        pass

Flask test client

Doc: http://flask.pocoo.org/docs/1.0/testing/

1. Start sample RestAPI

$ python test_client/app.py

Open http://localhost:5000/ui and try out sample Rest API

2. Run sample tests

$ pytest test_client

3. Create automated test for new Pet creation

def test_get_pets_on_empty_db(client):
    result = client.get('/pets')
    assert result.status_code == 200
    assert result.json == []


def test_put_pet(client):
    # TODO: Pet creation scenario
    pass
