Cannot add admin menu - composer module

Question

I am developing a new module which will provide access to a custom grid using left sided admin menu. The problem is that I cannot create a custom element in this admin menu.

The module is located under vendor folder, vendor/test/test-extension, with the following composer.json under module root:

{
  "name": "test/test-extension",
  "description": "test extension magento2",
  "type": "magento2-module",
  "version": "dev-master",
  "autoload": {
    "files": [
      "registration.php"
    ],
    "psr-4": {
      "Test\\TestExtension\\": ""
    }
  }
}

The module is included in autoload_psr4.php, being able to run install schema and getting models.

But, I'm not able to create a custom element in admin menu, simply it doesn't appear.

etc/acl.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Acl/etc/acl.xsd">

                    <resource id="Test_TestExtension::testentity" title="Entity" sortOrder="11"/>

                        </resource>
                    </resource>
                </resource>
            </resource>
        </resources>
    </acl>
</config>

etc/adminhtml/menu.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
    <menu>
        <add id="Test_TestExtension::testextension" title="Test extension" module="Test_TestExtension" sortOrder="61" resource="Test_TestExtension::testextension"/>
        <add id="Test_TestExtension::testentity" title="Test entity" module="Test_TestExtension" sortOrder="11" action="test_testextension/testentity" resource="Test_TestExtension::testentity" parent="Test_TestExtension::testextension"/>
    </menu>
</config>

Any ideas ?

Answer 1

Have you set the right to see this new menu ? In the BO : System > Permissions > User Role and modify the Roles Resources for the Administrators ? It could be necessary to set in module.xml a sequence to be sure that your module is after Magento_Backend Module.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Test_TestExtension" setup_version="1.0.0">
        <sequence>
            <module name="Magento_Backend"/>
        </sequence>
    </module>
</config>

I've made a mistake in registration.php. Wrong version was:

<?php   
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'test_test-extension',
    __DIR__
);

Instead of test_test-extension I've added Test_TestExtension (the module name included in psr4) and it's working fine.
