Continuous Integration with Salesforce DX: Practices and Principles for All

This talk draws on several past articles published here:

• Salesforce Lifecycle and Tooling: CircleCI and SFDX
• Integrating Static Analysis with PMD in the Salesforce Development Lifecycle
• Salesforce Lifecycle and Tooling: Testing on Multiple Org Types with Salesforce DX and CircleCI Workflows
• Integration Testing Off-Platform Code with Salesforce DX and simple_salesforce

Some additional resources and examples are available on my GitHub:

• circleci-sfdx-examples, a compendium of CircleCI/Salesforce DX examples, including a basic project, using the Lightning Testing Service, testing against multiple org shapes, and using PMD static analysis.
• sfdx-simplesalesforce, demonstrating how to test integrated code written in Python with simple_salesforce via Salesforce DX scratch orgs.
• septaTrains, my toy Lightning project (ever wanted your SEPTA regional rail commute on your Lightning homepage?) and testing project for different CI and automated testing solutions.
• DMRNoteAttachmentImporter, a slightly more useful package also building with SFDX on CircleCI.
