PHPSpec - Check if Method Returns a file

Question

I am new to phpspec, and I am trying to test if a method returns a file. The method is essentially:

public function getFile(){
    return file_get_contents('myFile.pdf');
}

So my initial though was to test if getFile() returns a string since file_get_contents returns a string according to the docs.

So my test looks like this:

$this->getFile()->shouldHaveType("string");

But my test fails with the following message:

expected an instance of string, but got "%PDF-1.4"....

I have even tried gettype(getFile()) and it returns "string".

Can anyone tell me what I am doing wrong.

You are checking for a type of class. But you really want to check if the data returned is of type string. @zerkms is correct. You should use a Scalar Matcher (http://www.phpspec.net/cookbook/matchers.html#scalar-matcher)

$this->getFile()->shouldBeString()
