Try giving it the full namespace (use App\SomeNamespace\Calculator; at the top of the test file)
$calculator = $this->getMockBuilder(Calculator::class)

PHPUnit Test Doubles: Test passes without SUT
The following test passes WITHOUT the underlying SUT
public function testWithStub()
{
// Create a stub for the LoanCalculator class.
$calculator = $this->getMockBuilder('Calculator')
->setMethods(['add'])
->getMock();
// Configure the stub.
$calculator->expects($this->any())
->method('add')
->will($this->returnValue(6));
$this->assertEquals(6, $calculator->add(100,100));
}
The class being tested doesn't exist. Why is the test passing?

@Sinnbeck I've imported an existing class using namespace. The test still passes even if the method being stubbed does'nt exist. The class has no method name 'add'

@kenprogrammer Yeah. It has been deprecated for this reason. If you check the source for the method, you will see this
@deprecated https://github.com/sebastianbergmann/phpunit/pull/3687
Use ->onlyMethods() instead. Or ->addMethods() if you want to add a method

@Sinnbeck Thanks for the clarification. I thinks the docs needs to outline it clearly.
Level 102
@kenprogrammer Yeah sadly it does not seem to be mentioned in the phpunit docs. Only mention of it is in the release notes: https://phpunit.de/announcements/phpunit-9.html But I think setMethods() will be removed completely in phpunit 10

And it is possible to mock classes that does not exist.

@Sinnbeck At what point should the test fail in accordance with TDD?
