Laravel unit testing same function twice and different output - unit-testing

Question

I'm a bit new to Laravel unit testing. I need to get different outputs by calling same repo function for the unit testing.
So far my test is like this:
public function testReportOffdayWorked()
{
$input = [
'from_date' => '2016/01/01',
'to_date' => '2016/01/03',
];
$webServiceRepositoryMock = Mockery::mock('App\Repositories\WebServiceRepository');
$webServiceRepositoryMock->shouldReceive('callGet')->twice()->andReturn($this->issues);
$this->app->instance('App\Repositories\WebServiceRepository', $webServiceRepositoryMock);
$this->call('post', '/reporting/portal/report-offdays', $input);
$this->assertResponseOk();
$this->assertTrue($this->response->original->getName() == "Reporting::report_offday_worked");
}
I would like to get two different outputs for callGet function.

Answer 1

Set up a sequence of return values or closures for callGet().
andReturn(value1, value2, ...)
Sets up a sequence of return values or closures. For example, the first call will return value1 and the second value2. Note that all subsequent calls to a mocked method will always return the final value (or the only value) given to this declaration.

The following shows how to do it in PHPUnit mocks and mockery.
<?php
class The {
public function answer() { }
}
class MockingTest extends \PHPUnit_Framework_TestCase
{
public function testMockConsecutiveCalls()
{
$mock = $this->getMock('The');
$mock->expects($this->exactly(2))
->method('answer')
->will($this->onConsecutiveCalls(4, 2));
$this->assertSame(4, $mock->answer());
$this->assertSame(2, $mock->answer());
}
public function testMockeryConsecutiveCalls()
{
$mock = Mockery::mock('The');
$mock->shouldReceive('answer')->andReturn(4, 2);
$this->assertSame(4, $mock->answer());
$this->assertSame(2, $mock->answer());
}
}

Answer 2

How about using PHPUnit mocking framework?
$mock = $this->getMock('ClassName');
$mock->expects($this->at(0))
->method('getInt')
->will($this->returnValue('one'));
$mock->expects($this->at(1))
->method('getInt')
->will($this->returnValue('two'));
echo $mock->getInt(); //will return one
echo $mock->getInt(); //will return two
