CI environment construction ~ Python edition ~

A free and easy way to set up a Python continuous integration environment

Services to use

-Travis CI (free CI environment) -CoverAll (a service that allows you to view the coverage of code executed by Travis CI) -Slack (Chat service that receives notifications from Travis CI)

Advance preparation

1. Get a GitHub account
2. Create repository
3. Install RubyGem (used for Travis command installation)

Travis CI account acquisition and repository selection

1. Sign in with your GitHub account from the link in the upper right
2. Turn on the repository you want to test

Test code

• tests/hoge_test.py
• src/fuga.py

tests/hoge_test.py

1. Display "test_first"
2. Call the index method of the Fuga class and check True.

tests/hoge_test.py

# coding:utf-8

import unittest
from fuga import Fuga

class HogeTest(unittest.TestCase):

    def setUp(self):
        print('setUp')

    def test_first(self):
        print('test_first')

    def test_fuga(self):
        fuga = Fuga()
        self.assertTrue(fuga.index())


def suite():
    suite = unittest.TestSuite()
    suite.addTests(unittest.makeSuite(HogeTest))
    return suite

tests/fuga.py

1. ʻindex ()`: Returns True.

src/fuga.py

# coding utf-8

class Fuga:

    def index(self):
        return True

setting file

• setup.py
• .travis.yml

setup.py

1. Execution environment setting script
2. Set the path of the code to be used for sys.path.append ()
3. Specify the test file name suite.addTests () in the code in test_suite in the format of" testfile_name.suite "

setup.py

from setuptools import setup, find_packages
import sys

sys.path.append('./src')
sys.path.append('./tests')

setup(
    name = 'Hoge',
    version = '0.1',
    description='This is test codes for travis ci',
    packages = find_packages(),
    test_suite = 'hoge_test.suite'
)

.travis.yml

1. Travis CI configuration file
2. python: version specification
3. ʻinstall:` install the coversalls package with pip
4. Run the test with the script: coverage command
5. ʻafter_script: Execute the `coveralls command
6. notifications: Notification settings for slack

yaml:.travis.yml

language: python

python:
  - 3.3
  - 3.4

install:
  - pip install coveralls

script:
  - coverage run --source=hoge_test setup.py test

after_success:
  - coveralls

notifications:
  slack:
    secure: your_token_key

-Refer to COVERALLS FOR PYTHON for cooperation with CoverAll. --See Configuring Build Notifications for notification settings. --See Encryption keys for how to encrypt your_token_key.

• If you are using rbenv, don't forget to rehash -** coversalls-python ** library no longer supports ** python 3.0 ~ 3.2 **, so set the test version to 3.3 or higher.
