Add whitelist to phpunit.xml and add directory for checking code coverage

        <whitelist>
            <directory suffix=".php">./models</directory>
        </whitelist>

Execute command:

./vendor/bin/phpunit --coverage-html ./report

This command will generate report to directory ./report

Codeception

Prepare. Remove all new versions of phpunit and dbunit

composer remove phpunit/dbunit
composer remove phpunit/phpunit
composer require phpunit/phpunit:"~4.8"
composer require phpunit/dbunit:"~1.4"

In your composer.json file you should see:

"phpunit/phpunit": "~4.8",
"phpunit/dbunit": "~1.4",

Installation

composer require "codeception/codeception=2.1.*"
composer require "codeception/specify=*"
composer require "codeception/verify=*"

Checking is codeception work

./vendor/bin/codecept

Delete ./test folder and ./phpunit.xml
Create configuration

./vendor/bin/codecept bootstrap

Copy ./tests/bin/yii from previous deleted version, add configuration in ./tests/config directory
Generate UserTest:

./vendor/bin/codecept generate:test unit UserTest

Copy non DbUnit methods from previous UserTest class.
Build

./vendor/bin/codecept build

Run it

./vendor/bin/codecept run
./vendor/bin/codecept run unit

Add Db module
- Add Db module to codeception.yml
- Add Db to unit.suit.yml
