Nuxeo: can I use local contribution to define directories when testing?

I need to test operations and listeners using vocabularies, they are present in my studio package but, from what I understand are not included when the package is deployed locally upon testing.

What am I missing? I have been running in circles for quite some time. I can't seem to find a solution anywhere.

Here is the error raised when running my test:

%ERROR  1,should_Pass(my.package.operations.SomeOperationTest)
%TRACES 
org.nuxeo.ecm.directory.DirectoryException: Failed to invoke operation SomeOperation, No directory registered with name: Some_Directory

This is the structure of my core project source folder:

main
  |- java
  |   |- my.package.operations
  |   |   |- SomeOperation.java
test
  |- java
  |   |- my.package.operations
  |   |   |- SomeOperationTest.java
  |- resources
  |   |- directories
  |   |   |- Some_Directory.csv
  |   |- OSGI-INF
  |   |   |- test-directories-contrib.xml

Here's my test class:

@RunWith(FeaturesRunner.class)
@Features(AutomationFeature.class)
@RepositoryConfig(cleanup = Granularity.METHOD)
@Deploy({
    "studio.extensions.my-studio",
    "my-bundle-symbolic-name",
    "my-bundle-symbolic-name:OSGI-INF/test-directories-contrib.xml"})
public class SomeOperationTest {

  @Inject
  OperationContext context;

  @Inject
  AutomationService automation;

  @Test
  public void should_Pass() throws OperationException {

    automation.run(context, "SomeOperation"); // raises exception

    // ... some assertion
  }
}

The failing operation is this:

@Operation(
    id = "SomeOperation",
    category = "Some",
    label = "Operation",
    description = "Opening a directory")
public class SomeOperation {

  @OperationMethod()
  public void run() {

    Framework.getService(DirectoryService.class).open("Some_Directory"); // raises exception

    // ... some more code
  }
}

The directory contribution:

<?xml version="1.0"?>
<component name="my.package.test.directories">
  <extension target="org.nuxeo.ecm.directory.GenericDirectory" point="directories">
    <directory name="Some_Directory" extends="template-directory">
      <schema>vocabulary</schema>
      <idField>id</idField>
      <autoincrementIdField>false</autoincrementIdField>
      <dataFile>directories/Some_Directory.csv</dataFile>
      <createTablePolicy>on_missing_columns</createTablePolicy>
    </directory>
  </extension>
</component>

The .csv file for the directory looks like this:

id,label,obsolete
"some","entry","0"
