Approach on Monkey::action expects different values on consecutive calls

test.php

<?php
Brain\Monkey::actions()
	->expectFired( 'do_something' )
	->twice()
	->withArgs(
		[
			'first',
			'second'
		]
	);

do_action( 'do_something', 'first' );
do_action( 'do_something', 'second' );

//Mockery\Exception\NoMatchingExpectationException: No matching handler found for Mockery_0__do_do_something::do_action_do_something("first"). Either the method was unexpected or its arguments matched no expected argument list for this method

It seems that this issue mockery/mockery#459 I opened an year ago, has been implemented. In next version of Mockery the manual version can become:

Brain\Monkey::actions()
  ->expectFired( 'do_something' )
  ->twice()
  ->withArgs(function($arg) {
        static $i = -1;
        $i++;
        $expected = ['first', 'second'];
        $this->asssertSame($expected[$i], $arg);
  });

So you can use whenHappen for what it is intentended to be used...

Thanks a lot, Giuseppe!

This is possible for normal objects, if it does not work, it is a Brain Monkey bug: an issue would be much appreciated.
I'll figure out and will create an issue if there's one.

Yes, currently went with something like

Brain\Monkey::actions()
    ->expectFired( 'do_something' )
    ->twice()
    ->with( Mockery::on( function( $arg ) {
        // test $arg here
        return TRUE;
    } ) );
