/**
 * 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();
 * }
