+        <p>In the context of <b>.NET Core APIs</b> for a blog, integration tests are automated tests that evaluate the functionality of various parts of your application working together as a whole. Specifically, these tests ensure that multiple components — such as controllers, database access, middleware, internal and external services — function correctly when integrated, as opposed to functioning correctly only in isolation (which would be covered by unit tests).</p>
