Laravel how to set app environment during tests

Laravel Testing Environment

If you need to set an environment to be a specific one such as staging you can override the environment by changing the config value app_env

config(['app.env' => 'staging']);

Then doing a dd on config(‘app.env’) will return that environment you’ve just set.

I haven’t found a way to set environments with app()->environment() so instead, I recommend using this in_array function and passing in the config(‘app.env’) and then specifically defining the environments.

in_array(config('app.env'), ['local', 'staging'])

For example, say you have this in a command:

if (! in_array(config('app.env'), ['local', 'staging'])) { $this->error(‘Will only run on local and staging environments’); return true; }

Test this runs when the environment is set to production

test(‘cannot run on production’, function () {

config(['app.env' => 'production']);

$this->artisan('db:production-sync') ->expectsOutput(‘DB sync will only run on local and staging environments’) ->assertExitCode(true); });
