Since the request was made a required argument to the `render()` method in #6829, this [test became a duplicate](https://github.com/fabpot/symfony/blob/23f51450bd5af35055db47b1787b5623b78df29b/src/Symfony/Component/HttpKernel/Tests/RenderingStrategy/EsiRenderingStrategyTest.php#L28-L38) of `testRenderFallbackToInlineStrategyIfEsiNotSupported()`.
