Difference between assertEquals and assertSame in PHPUnit?

Question

PHPUnit contains an assertEquals() method, but it also has an assertSame() one. At first glance it looks like they do the same thing.

What is the difference between the t

Answer 1

assertSame() == Tests that if the actual output and the expected parameter are same.

that is :

$this->assertSame('$expected','$expected');

or

$this->assertSame('100','100');

assertEquals == If we see with respect to a website page, i have a page which has 2 'table' so when i run assertEquals i will check its count that the 'table' are 2 by using a count function. Eg:

$this->assertEquals(2, $var->filter('table')->count()); 

Here we can see that assertEquals checks that there are 2 tables found on the web page. we can also use divisions found on the page using '#division name' inside the bracket.

Eg 2:

public function testAdd()
{
    $calc = new Calculator();

    $result = $calc->add(30, 12);

    // assert that our calculator added the numbers correctly!
    $this->assertEquals(42, $result);
}
