Deploy Salesforce Apex Without Failing the 75% Test Coverage Rule
You push an Apex change to production and the deployment stops:
Average test coverage across all Apex Classes and Triggers is 71%, at least 75% test coverage is required to complete this deployment.
It passed in the sandbox. In production, the org-wide coverage gate — and the rule that one failing test fails the whole deploy — blocks the release. mtdt.io avoids this by recommending exactly which unit tests cover your change, so you deploy with Run Specified Tests — a targeted run — instead of RunAllTests against the whole org.
