Continuous Integration in Salesforce using Salesforce DX

When many people work on a project, managing changes become difficult. Continuous Integration is the approach of running checks after every change, to catch errors quickly, before it becomes difficult and time-consuming to track down the errors.

Running Continuous Integration in Salesforce is proven to deliver huge cost savings and accelerate the time-to-market. The essentials to run Continuous Integration (CI) are Salesforce DX, GitHub, or the shared repository, and any CI server, such as Travis CI. The developers make their changes in Salesforce CX, and every time they upload the changes to GitHub, the CI server runs a script which triggers a set of pre-defined tests. 

The CI development approach requires selecting an appropriate CI tool, setting the rules to run tests, deciding on the environment model and development strategy, automating the test process, and creating a delivery pipeline.
