Create pipeline with coverage and tests checks

[victordmontero]

Scope

To make sure the delivered code gets merged to master, some checks are going to be necessary. These checks will make sure the code is at least on working state before merging into the master branch

Steps

• Add a .yaml file under .github/workflows (mkdir that directory if it doesn't exist).
• It should run the tests and additionally check that the coverage is above some threshold (it could be 85%) to be acceptable.
• It should trigger when creating a pull request to master branch.
• As an example check this yaml file

Dod
