#javascript
Scenario: List 2 files in a directory
Given I am on the homepage
Then I should see "hello"
When I go to "/ajoutermed"
Then I should see "ajouter"
And I wait 2 seconds

Answer 1

regarding your error message, there is an ambigous "#When I press" action. If you change your function iPress by
/**
* #When I click on input :arg1
*/
public function iClickOnInput($arg1)
{
self::$driver->findElement(WebDriverBy::cssSelector($arg1))->click();
//$element = $page->find('css',"input[value='$arg1']");
}
It should work.

Answer 2

If is a button element and it has Ajouter Med as one of the following id|name|title|alt|value then it should work with I press "Ajouter Med"
If this is a link then you should use I follow "Ajouter Med"
Make sure you try to search the appropriate method to use, try using an IDE editor with autocomplete for Behat/Gherkin steps and for php methods.
Avoid writing your own custom base methods/steps, do this only if you have no alternative, you might end with 2-3 steps that are doing the same thing.
