I installed MFTF stand alone and have a magento instance. Just following the getting started document before I write tests of my own. When generated/run the test it gives error - Could not retrieve API token from Magento Instance (302 Found).

Any help is really appreciated

In ModuleResolver.php line 444:

Could not retrieve API token from Magento Instance (302 Found)

generate:tests [-c|--config CONFIG] [-f|--force] [-i|--time TIME] [-t|--tests TESTS] [-d|--debug] [-r|--remove] [--] [...]

probably you have wrong credentials to Magento instance.

Look in ModuleResolver where API token is retrieving from Magento:

     * Get the API token for admin.
     * @return string|boolean
    protected function getAdminToken()
        $login = $_ENV['MAGENTO_ADMIN_USERNAME'] ?? null;
        $password = $_ENV['MAGENTO_ADMIN_PASSWORD'] ?? null;
        if (!$login || !$password || !$this->getBackendUrl()) {
            $message = "Cannot retrieve API token without credentials and base url, please fill out .env.";
            $context = [
                "MAGENTO_BASE_URL" => getenv("MAGENTO_BASE_URL"),
            throw new TestFrameworkException($message, $context);

        $url = ConfigSanitizerUtil::sanitizeUrl($this->getBackendUrl()) . $this->adminTokenUrl;
        $data = [
            'username' => $login,
            'password' => $password
        $headers = [
            'Content-Type: application/json',

        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        $response = curl_exec($ch);
        $responseCode = curl_getinfo($ch)['http_code'];

        if ($responseCode !== 200) {
            if ($responseCode == 0) {
                $details = "Could not find Magento Backend Instance at MAGENTO_BACKEND_BASE_URL or MAGENTO_BASE_URL";
            } else {
                $details = $responseCode . " " . Response::$statusTexts[$responseCode];

            $message = "Could not retrieve API token from Magento Instance ({$details})";
            $context = [
                "tokenUrl" => $url,
                "responseCode" => $responseCode,
            throw new TestFrameworkException($message, $context);

        return json_decode($response);

My advice is to check .env file in ROOT/dev/test/acceptance/.env

  • In .env file, default admin name or admin registration name?

  • MAGENTO_BASE_URL= URL for frontend MAGENTO_BACKEND_NAME= URL name for backend(default after magento installation is admin_xxxxxxx. You can check in MAGE_ROOT/app/etc/env.php) MAGENTO_ADMIN_USERNAME= admin login MAGENTO_ADMIN_PASSWORD= admin password Commented Jul 24, 2019 at 5:16
  • in my case there is no .env file what should I do now?

If you got this problem You should change info of file dot-env related with your instance such as MAGENTO_BASE_URL MAGENTO_ADMIN_USERNAME MAGENTO_ADMIN_PASSWORD
Make sure set write permissions recurssive to folder



I've got the same message when I forgot to make

php bin/magento setup:upgrade

after I added some modules and tried to generate MFTF tests.
