|||||||
* **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 a unit test into the environment checker!

|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
Register checks in your own `_config.php` - see the `_config.php` in this module for some defaults.
|
||||||
|
|
||||||
|
:::php
|
||||||
|
EnvironmentCheckSuite::register('health', 'DatabaseCheck', "Can we connect to the database?");
|
||||||
|
EnvironmentCheckSuite::register('check', 'URLCheck("")', "Is the homepage accessible?");
|
||||||
|
|
||||||
|
## Available checks
|
||||||
|
|
||||||
|
* `DatabaseCheck`: Check that the connection to the database is working, by looking for records in some table. By default, Member will be checked.
|
||||||
|
* `URLCheck`: Check that a given URL is functioning, by default, the homepage.
|
||||||
|
* `HasFunctionCheck`: Check that the given function exists.
|
||||||
|
This can be used to check that PHP modules or features are installed.
|
||||||
|
* `HasClassCheck`: Check that the given class exists.
|
||||||
|
This can be used to check that PHP modules or features are installed.
|
||||||
|
* `FileWriteableCheck`: Check that the given file is writeable.
|
||||||
|
* `FileAgeCheck`: Checks for the maximum age of one or more files or folders.
|
||||||
|
Useful for files which should be frequently auto-generated,
|
||||||
|
like static caches, as well as for backup files and folders.
|
||||||
|
* `ExternalURLCheck`: Checks that one or more URLs are reachable via HTTP.
|
||||||
|
* `SMTPConnectCheck`: Checks if the SMTP connection configured through PHP.ini works as expected.
|
||||||
|
|
||||||
## Adding more checks
|
## Adding more checks
|
||||||
|
|
||||||
To add more checks, you should put additional `EnvironmentCheckSuite::register` calls into your `_config.php`. See the `_config.php` file of this module for examples.
