Overwrite Environment Variable Params with export BEHAT_PARAMS

Question

I am trying to use environment-variable-behat-params to overwrite the following value in my YAML:

my_profile:
   suites:
      domain:
         contexts:
            - MyContext:
               - my_config:
                  setting_setting: data
                  other_setting_setting: other_data

This is the export command:

export BEHAT_PARAMS='{"suites":{"domain":{"contexts":{"MyContext":{"my_config":{"my_setting":"on"}}}}}}'

And this is the PHP code:

/** @BeforeSuite */
public static function prepare(BeforeSuiteScope $scope) {
    $my_settings = $scope->getEnvironment()
        ->getContextClassesWithArguments()['MyContext'][0];

    if (isset($my_settings['my_setting']) && $my_settings['my_setting'] == 'on') {
        //do something here
    }
}

It seems to match the documentation, but my_setting remains off instead of being updated to on.

If I try to use a key which is at the root level of my_profile like this:

my_profile:
   my_config:
     setting_setting: data

With this is the export command:

export BEHAT_PARAMS='{"my_config":{"my_setting":"on"}}'

Then I get this error:

In ArrayNode.php line 311:

[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException] Unrecognized option "my_settings" under "testwork"

.. how can I fix this?

Might be wrong but you are using the key DomainContext on you env variable and then looking for MyContext in your code, could it be that? — gvf
@gvf in short MyContext is DomainContext. I've updated the question so that the ambiguity is removed. — Barry

you just need to remove my_setting from your yaml file because it super-cedes any environment variable

from the documentation link you provided

in order to specify a parameter in an environment variable, the value must not exist in your behat.yml
