Mock in PHPUnit - multiple configuration of the same method with different arguments

Question

Is it possible to configure PHPUnit mock in this way?

$context = $this->getMockBuilder(\'Context\')
   ->getMock();

$context->expects($this->any         


        

Answer 1

Here are also some solutions with the doublit library :

Solution 1 : using Stubs::returnValueMap

/* Get a dummy double instance  */
$double = Doublit::dummy_instance(Context::class);

/* Test the "offsetGet" method */
$double::_method('offsetGet')
    // Test that the first argument is equal to "Matcher" or "Logger"
    ->args([Constraints::logicalOr('Matcher', 'Logger')])
    // Return "new Matcher()" when first argument is "Matcher"
    // Return "new Logger()" when first argument is "Logger"
    ->stub(Stubs::returnValueMap([['Matcher'], ['Logger']], [new Matcher(), new Logger()]));

Solution 2 : using a callback

/* Get a dummy double instance  */
$double = Doublit::dummy_instance(Context::class);

/* Test the "offsetGet" method */
$double::_method('offsetGet')
    // Test that the first argument is equal to "Matcher" or "Logger"
    ->args([Constraints::logicalOr('Matcher', 'Logger')])
    // Return "new Matcher()" when first argument $arg is "Matcher"
    // Return "new Logger()" when first argument $arg is "Logger"
    ->stub(function($arg){
        if($arg == 'Matcher'){
            return new Matcher();
        } else if($arg == 'Logger'){
            return new Logger();
        }
    });
