* Notes: |
|
12
|
|
|
* |
|
13
|
|
|
* It was necessary to extend the AbstractFileLoader instead of implementing \Behat\Gherkin\Loader\FileLoaderInterface |
|
14
|
|
|
* because I had to get access to the findAbsolutePath method. |
|
15
|
|
|
* |
|
16
|
|
|
* Fun fact: The findAbsolutePath method is the exact same method |
|
17
|
|
|
* as the one in \Behat\Behat\Gherkin\Specification\Locator\FilesystemFeatureLocator |
|
18
|
|
|
* so it is already duplicated in the main project. |
|
19
|
|
|
* |
|
20
|
|
|
* @TODO Create some kind of service which exposes a public findAbsolutePath and contribute it back to Behat |
|
21
|
|
|
* to avoid copy-pasting and relying on implementation details like this AbstractFileLoader |
