Behat selenium tests trust self signed SSL cerificate - rest

Question

For our automated testing of our Drupal site, we are using Behat test scripts. On our local development machines we are using a self signed SSL certificate that is created by Acquia Devdesktop. Running the tests in the different browsers with Behat is no problem since you can trust the certificate in the browser itself. However for the REST interfaces where no browser is being opened it is a different story. Behat will not accept the self signed certificate since it is "unsecure".
When running the REST test this is the error we get:
cURL error 60: SSL certificate problem: self signed certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html) (GuzzleHttp\Exception\RequestException)
With the testcase itself is nothing wrong because it worked before we enabled the SSL certificate. We tried to edit the configuration .yml file with the options from the documentation and other tickets but with no luck.
Is there a way to trust a self signed certificate for the REST interface tests? If you need more information please let me know.
Edit: Added the YML config and composer.json file
//composer.json
{
"require": {
"drupal/drupal-extension": "~3.0",
"emuse/behat-html-formatter": "dev-master",
"behatch/contexts": "*",
"guzzlehttp/guzzle": "dev-master",
"behat/mink-goutte-driver": "dev-master"
},
"config": {
"bin-dir": "bin/"
}
}
Note I removed my url from the yml file below.
