Salesforce Winter '27 for Developers: Apex Integration Tests, SOQL FORMULA() and a Bigger Heap

Описание: Salesforce Winter '27 for developers, tried hands-on: Apex integration tests that make real web service callouts, the FORMULA() function in SOQL for comparing two fields, and higher Apex heap limits.

You'll learn:
Why a regular Apex test can't make a real callout, and what a mock can't tell you
How to set up a Developer Edition scratch org for Apex integration tests (a developer preview) and run one from the CLI
Why Tear Down matters when integration test data is committed
How FORMULA() compares two fields in a WHERE clause, and what the beta (outside production) accepts
How to check your org's heap limit, and the non-production setting named after the old one
