RunAs in tests

Learn RunAs in tests in Apex with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

12 min read • Advanced

RunAs in tests is an atomic Apex topic inside Security & Sharing. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what RunAs in tests changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

apex-07-10-runas-in-tests.cls
apex Try It Live
System.runAs(testUser){ System.assertEquals(testUser.Id, UserInfo.getUserId()); }
Edge case / engineering note

Change the key input in this Apex example and predict the result first; the named construct should be the reason the behavior changes.
