Explainer

Code coverage measures the percentage of executable Apex lines exercised by test methods to indicate test effectiveness. Salesforce requires a minimum of 75% coverage for deployment or AppExchange packaging, provided all tests pass.

Core information
  • Coverage is calculated by dividing the number of covered lines by the sum of covered and uncovered executable lines.
More details and nuances
  • Deployments fail if the overall organization coverage drops below 75%, even if the new components themselves have 100% coverage.
