How to simulate file upload in php command line

Question

I'm new to PHPUnit testing framework.

as we know that move_uploaded_file() function of PHP will not work until the file is uploaded via http POST method

So, the Question is how to simulate this in PHP command line

Note: using selenium we can simulate webform.. but i need another alternative.

You basically need to make your code more testable. Break it down so you can test the simple act of uploading a file through HTTP separately from the rest of the code. The primary use of move_uploaded_file is to put in an extra security stop so you cannot be tricked into moving some other file, move_uploaded_file simply makes sure that the file was uploaded in the same request and then moves it. You can simply move the file using rename as well. As such, break your application down to have one Request object which represents and encapsulates the current HTTP request, including making it check uploaded files using is_uploaded_file. Once that's validated, you can use rename instead of move_uploaded_file. In your tests you can then mock the Request object and test your other code.

You can also simply make move_uploaded_file mockable, for example like this:

class Foo {

    public function do() {
        ...
        $this->move_uploaded_file($from, $to);
        ...
    }

    protected function move_uploaded_file($from, $to) {
        return move_uploaded_file($from, $to);
    }

}

In your tests you can extend/mock the class and override Foo::move_uploaded_file to always return true, for instance.
