MongoDb

Installation

If you use Codeception installed using composer, install this module with the following command:

composer require --dev codeception/module-mongodb

Alternatively, you can enable MongoDb module in suite configuration file and run

codecept init upgrade4

This module was bundled with Codeception 2 and 3, but since version 4 it is necessary to install it separately.
Some modules are bundled with PHAR files.
Warning. Using PHAR file and composer in the same project can cause unexpected errors.

Description

Works with MongoDb database.

The most important function of this module is cleaning database before each test. To have your database properly cleaned you should configure it to access the database.

In order to have your database populated with data you need a valid js file with data (of the same style which can be fed up to mongo binary) File can be generated by RockMongo export command You can also use directory, generated by

mongodump

tool or it’s

.tar.gz

archive (not available for Windows systems), generated by

tar -czf <archive_file_name>.tar.gz <path_to dump directory>

. Just put it in

tests/_data 

dir (by default) and specify path to it in config. Next time after database is cleared all your data will be restored from dump. The DB preparation should as following:

• clean database
• system collection system.users should contain the user which will be authenticated while script performs DB operations

Connection is done by MongoDb driver, which is stored in Codeception\Lib\Driver namespace. Check out the driver if you get problems loading dumps and cleaning databases.

HINT: This module can be used with Mongofill library which is Mongo client written in PHP without extension.
