Almost, but not really. Environment checks differ from unit tests in two important ways:
* **They test environment specific settings.** Unit tests are designed to use dummy data and mock interfaces to external system. Environment checks check the real systems and data that the given environment is actually connected to.
* **They can't modify data.** Because these checks will run using production databases, they can't go modifying the data in there. This is the biggest reason why we haven't used the same base class as a unit test for writing environment checks - we wanted to make it impossible to accidentally plug the a unit test into the environment checker!

If you want to use the same UI as dev/health and dev/check, you can create an `EnvironmentChecker` object. This class is a `RequestHandler` and so can be returned from an action handler. The first argument to the `EnvironmentChecker` constructor is the suite name. For example:

* `$result->Details()`: A `DataObjectSet` of details about the result of each check in the suite.
