PHP Fatal error: Duplicate type null is redundant

[foremtehan]

PHP 8.0
Mockery v1.4.2

I want to mock php built-in class ZipArchive :

$zip = Mockery::mock(ZipArchive::class);

$zip->shouldReceive('open')->andReturn(true);

But i get this error:

PHP Fatal error: Duplicate type null is redundant in \vendor\mockery\mockery\library\Mockery\Loader\EvalLoader.php(34) : eval()'d code on line 1176

In EvalLoader.php(34) : eval()'d code line 1176:

I was experiencing the same error for a custom class I am working on. It seems that my issue was related to how I had set up the following constructor that was attempting to be mocked:

public function __construct(AlpacaTrading $tradingApi, Order|array $order = null)
{
    parent::__construct($tradingApi);

    return $order ? $this->from($order) : $this;
}

It didn't like having to mock the type-hinted nullable param $order. Changing the constructor to the following alleviated the issue for me.

public function __construct(AlpacaTrading $tradingApi, array $order = null)
{
    parent::__construct($tradingApi);

    return $order ? $this->from($order) : $this;
}

Reckon I'm hitting this one too, with PHP8.0 and Mockery 1.4.2

Trying to mock a class with this method cause the "Duplicate type" error:

public function add(ActionableInterface $component, array|string|null $definition, ?string $type = null): void
{
    //...
}

Changing the type hint for $definition to mixed resolves the error, but is obviously not desirable.

On investigation, this was fixed in #1106

Looks like it's just waiting for a new release

@davedevelopment any chance this could be released soon please?

[davedevelopment]

Sorry for the delay, will see if I can schedule some time this week to merge the branches and release.

Thanks for the release @davedevelopment
