Automate Unit Tests Execution in Salesforce

In Salesforce, it is crucial to have proper control over our unit tests to avoid surprises when deploying our classes to production. Salesforce requires us to create unit tests that cover at least 75% of the code in our class to allow deployment. There are some nuances to this requirement, as we can have the overall coverage from multiple classes compensate for classes with lower coverage by classes with higher coverage, but that is not the focus of this article.

The goal of this article is to create an automated unit test runner in Salesforce. This idea is not originally mine; I learned it from a colleague a long time ago. However, all the code I will provide is my original work, and you have permission to use and modify it to your liking. Having proactive control over our unit tests will prevent us from reacting to test failures when trying to deploy any changes to production.
