Apex test methods run in a data silo by default, meaning they can only access records they create during the test execution rather than pre-existing organization data. The @isTest(SeeAllData=true) annotation can override this restriction to allow queries against existing org records, but this should be used sparingly. Test data isolation ensures predictable test results and prevents tests from breaking when org data changes.
