Question

I have a mockup of a service class. It's defined like this in my setUp function

$this->myServiceMockup = $this->getMockBuilder(MyService::class)
            ->disableOriginalConstructor()
            ->setMethods(['myMethod'])
            ->getMock();

In my test function i set an expectation for it like this.

$this->myServiceMockup->expects($this->once())
            ->method('myMethod')
            ->with($this->exactly(1), 'myName')
            ->willReturn($this->exactly(1));

So what this means is that when i should trigger the myMethod function only once and that it will return integer 1.

So method that I'm testing has that line of code.

$myIntValue = $this->myService->myMethod($number, $name);

After this line $myIntValue when i run the test should be 1 and test should continue, well that's my understanding on this.

But instead I get this error

Expectation failed for method name is equal to when invoked 1 time(s) Parameter 0 for invocation

My\Path\To\Class\MyService::myMethod(1, 'myName') does not match expected value.

1 does not match expected type "object".

Doesn't make any sense since myMethod is expecting an integer and a string.

public function myMethod($number, $name)
{
    return $this->table->save($number, $name);
}

Can somebody explain to me what am I doing wrong here, because I'm out of ideas.

Answer 1

The exactly() is an invocation count matcher (like once() or any()) for using as argument of the expects() method.

Just replace the:

->with($this->exactly(1), 'myName')

to

->with(1, 'myName')

The willReturn() also accepts values "as is".
