I may dont understand the concept of testing. Here is a function:
$qb->select('u')
->from('User', 'u')
->where('u.id = ?1')
->orderBy('u.name', 'ASC');
it is then "very" easy to write a mock, replace, expect the parameters, expect something result, etc. This is also detached from the database (no need real database then).
But what if I miss the ordering? I can still write a good test for it, without making sure it actually works. Another example:
function add($a, $b)
{
return $a-$b;
}
our imaginary test:
function testAdd()
{
$a = 1;
$b = 4;
$mock = $this->getMock(test);
$mock->expects($a)->once()->with(1);
$mock->expects($b)->once()->with(4);
$this->assertEquals (-4324,534, testAdd($a, $b);
}
this (fictional) test is similar to database test above. Lets take some parameters, expect that they run once, and produces a fake value. But actually, I still dont know it my "Add" method works well.
