Problem integrating Yii2 + codeception unit testing

Hi! I am having some troubles integrating yii2 with codeception unit testing, I can’t configure the “Db” module. When I run the tests this message appears in the console:


[Codeception\Exception\Module]

(Exception in Db) could not find pgsql driver while creating PDO connection



And this is odd because I already have other apllications working with PDO, yii2-basic template for instance.

— unit.suite.yml —


class_name: UnitTester

modules:

  enabled: 

    - Asserts

    - UnitHelper

    - Db

  config:

    Db:

      dsn: 'pgsql:host=127.0.0.1;dbname=testes'

      user: 'root'

      password: '123456'

I don’t know what I’m doing wrong, have anyone experienced this?

Anderson.
