+/**
+ * Class Jetpack_Constants
+ *
+ * Testing constants is hard. Once you define a constant, it's defined. Jetpack_Constants is an
+ * abstraction layer so that unit tests can set "constants" for tests.
+ *
+ * To test your code, you'll need to swap out `defined( 'CONSTANT' )` with `Jetpack_Constants::is_defined( 'CONSTANT' )`
+ * and replace `CONSTANT` with `Jetpack_Constants::get_constant( 'CONSTANT' )`. Then in the unit test, you can set the
+ * constant with `Jetpack::set_constant( 'CONSTANT', $value )` and then clean up after each test with something like
+ * this:
+ *
+ * function tearDown() {
+ *     Jetpack_Constants::clear_constants();
+ * }
