Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Adding Apex Code to a AppExchange App

You can include an Apex class or trigger in an app that you’re creating for AppExchange.

Any Apex that is included as part of a package must have at least 75% cumulative test coverage. Each trigger must also have some test coverage. When you upload your package to AppExchange, all tests are run to ensure that they run without errors. In addition, tests with the@isTest(OnInstall=true) annotation run when the package is installed in the installer's organization. You can specify which tests should run during package install by annotating them with @isTest(OnInstall=true). This subset of tests must pass for the package install to succeed.
