Composer require-dev requireing dependencies in different packages require-dev

Question

I have some tests that are namespaced being autoloaded in package A using

"autoload-dev": {
    "psr-4": {
        "Vendor\\PackageA\\PhpUnit\\": "tests/PhpUnit"
    }
},

This works fine.

I have another package, package B which also have namespaced tests that require one of the namespaced tests in package A

"autoload-dev": {
    "psr-4": {
        "Vendor\\PackageB\\PhpUnit\\": "tests/PhpUnit"
    }
},

However, when I try and include the file in Package B, the class is not found

use Vendor\PackageA\PhpUnit\MyTestFromA;

class MyTestFromB extends MyTestFromA
{

Making me think that the autoload-dev stuff from other packages is not being loaded.

PHP Fatal error: Class 'Vendor\PackageA\PhpUnit\MyTestFromA' not found in /full/path/to/PackageBClass.php on line 3

When I try and import a file that is being autoloaded using autoload from package B rather than autoload-dev, I get no error.

How can I overcome this?

Part of me is thinking to make a package just for the tests and have it autoloaded in both without autoload-dev but I want to confirm first.

Solution: Composer autoload-dev does not work.

Take a look at the docs. It says: "autoload-dev (root only)". root only means it only applies to the root package. As you included the package, the shown composer.json file is not the root package and the autoload-dev section is thus ignored.
