Fatal error when using closure in callback matcher

[klinki]

Hi,
I'm trying to create a mock with headers validation. I'm using callback for that.

I'm getting this error:

Fatal error: Function name must be a string in /vendor/jeremeamia/SuperClosure/src/SerializableClosure.php(210) : eval()'d code on line 2

My code looks like this:

$method = 'POST';
$path = '/path';
$requestHeaders = [
   'Content-Type' => 'application/json'
];

$this->http->mock
            ->when()
            ->methodIs($method)
            ->pathIs($path)
            ->callback(static function(Request $request) use($requestHeaders) {
                foreach ($requestHeaders as $header => $value) {
                    if (!$request->hasHeader($header) || $request->getHeader($header) != $value) {
                        return false;
                    }
                }
                return true;
            })
            ->then()
            ->statusCode(200)
           ->body('ok')
           ->end();

Because of that bug, I cannot validate expected request headers. Could you please provide some alternative method to validate request headers until this issue is fixed?

Thanks

Which version of super closure are you using? Which version of PHPUnit are you using?

[klinki]

I'm using PHPUnit 5.5.0 and SuperClosure 2.2.0

Can you try changing your setup to this:

$this->http->mock
            ->when()
                ->methodIs($method)
                ->pathIs($path)
                ->callback(static function(Request $request) use ($requestHeaders) {
                    foreach ($requestHeaders as $header => $value) {
                        if (!$request->headers->has($header) || $request->headers->get($header) !== $value) {
                            return false;
                        }
                    }
                    return true;
                })
            ->then()
                ->statusCode(200)
                ->body('ok')
            ->end();

I tried it and result is the same as before - fatal error again.

Hmmmm, that’s strange. What's your PHP version?

[klinki]

5.6.23

Very weird, I tried exactly your example locally with both PHP 7 and PHP 5.6 and I am unable to reproduce it. Can you try digging down vendor/jeremeamia/SuperClosure/src/SerializableClosure.php +210 and see how far you come?
