Codeception is configurated using the codeception.yml file. But, you don't want to store any credentials in this file. You can use a dotenv configuration file to store these data (for example database credentials) and use them in our code and codeception.yml file.
Head over to the phpdotenv repository to learn more about dotenv configuration and why you should use it.
Set up .env
First, create a
.env.example file in the root of your repository. Fill it with all the names of variables that you need, but do not fill in the actual data:
DB_HOST= DB_PORT= DB_DATABASE= DB_USERNAME= DB_PASSWORD=
.env and set all the variables to their correct values:
DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=myproject DB_USERNAME=homestead DB_PASSWORD=secret
Add the example file to Git. Add .env to your .gitignore list, never add it to your repository.
This is the
codeception.yml that I've used for a recent project:
actor: Tester paths: tests: tests log: tests/_output data: tests/_data support: tests/_support envs: tests/_envs settings: bootstrap: _bootstrap.php colors: true memory_limit: 1024M extensions: enabled: - Codeception\Extension\RunFailed modules: config: Db: dsn: "mysql:host=%DB_HOST%:%DB_PORT%;dbname=%DB_DATABASE%" user: "%DB_USERNAME%" password: "%DB_PASSWORD%" params: - .env
As you can see the last line instructs Codeception to load the .env file and read all variables that it contains.
You can use these variables in your configuration like you see in the database configuration parts.
%DB_HOST% with be replaced with the value of
Using variables in your code
All variables will be assigned to the global
$_ENV variable. So, in your PHP code, you can read from
$_ENV['DB_HOST'] to retrieve the same value as before.

Failed loading params from .env
`vlucas/phpdotenv` library is required to parse .env files.
Please install it via composer: composer require vlucas/phpdotenv
I have it installed and it is in my compsoser.json file. Any tips?
