+## Tool:
+We use `codeception` for testing. You shall have installed `codeception` via `composer` in order to run the tests.
+
+
+## How to write tests:
+All tests shall be in `__tests__/Unit/` folder. And shall be named as `*Test.php`. All test functions shall be named as `test*` (see example).
+
+Import sdk:
+
+```php
+require_once(dirname(dirname(__DIR__)) . '/vendor/autoload.php');
+```
+
+Good practice is to use `_before` to configure sdks APIs:
+```php
+
+    //example
+    protected function _before()
+    {
+        //load .env
+        $env = parse_ini_file('.env');
+
+        $config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setApiKey('X-App-Id', $env["X_APP_ID"]);
+        $config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setApiKey('X-App-Token', $env["X_APP_TOKEN"]);
+        $config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setHost($env["VOUCHERIFY_HOST"]);
+
+        $this->productsApiInstance = new OpenAPI\Client\Api\ProductsApi(
+            new GuzzleHttp\Client(),
+            $config
+        );
+        $this->campaignsApiInstance = new OpenAPI\Client\Api\CampaignsApi(
+            new GuzzleHttp\Client(),
+            $config
+        );
+        $this->redemptionsApiInstance = new OpenAPI\Client\Api\RedemptionsApi(
+            new GuzzleHttp\Client(),
+            $config
+        );
+    }
+
+```
+
+Test example:
+```php
+    //example
+    public function testListRedemptions()
+    {
+        $this->redemptionsApiInstance->listRedemptions(1, 1);
+    }
+```
+
+
+## Environment variables:
+`.env` file shall be in the root of the project and shall contain `X_APP_ID`, `X_APP_TOKEN` and `VOUCHERIFY_HOST` variables. Check `.env.example` for reference.
