Automating the Execution of Your Tests - zamaniamin/python GitHub Wiki

So far, you have been executing the tests manually by running a command. There are some tools for executing tests automatically when you make changes and commit them to a source-control repository like Git. Automated testing tools are often known as CI/CD tools, which stands for “Continuous Integration/Continuous Deployment.” They can run your tests, compile and publish any applications, and even deploy them into production.

Travis CI is one of many available CI (Continuous Integration) services available.

Travis CI works nicely with Python, and now that you’ve created all these tests, you can automate the execution of them in the cloud! Travis CI is free for any open-source projects on GitHub and GitLab and is available for a charge for private projects.

To get started, login to the website and authenticate with your GitHub or GitLab credentials. Then create a file called .travis.yml with the following contents:


```yaml
language: python
python:
  - "2.7"
  - "3.7"
install:
  - pip install -r requirements.txt
script:
  - python -m unittest discover

This configuration instructs Travis CI to:

  1. Test against Python 2.7 and 3.7 (You can replace those versions with any you choose.)
  2. Install all the packages you list in requirements.txt (You should remove this section if you don’t have any dependencies.)
  3. Run python -m unittest discover to run the tests

Once you have committed and pushed this file, Travis CI will run these commands every time you push to your remote Git repository. You can check out the results on their website.
