I am using phpunit PHPUnitFrameworkTestCase to test some controller action.

At some point in the code, I call some API that I want to mock

public function storeData($id)
{
    $someService  = new SomeService();
    $resp = $someService->getDataById($Id);

    ...
}

What I am mocking is getDataById() from SomeService
But for some reason I get Method was expected to be called 1 times, actually called 0 times

Is it because its nested inside another function?

Any ideas?

The test is something like this:

private function setApiMock($ID): void
{
        $apiMock = $this->getMockBuilder(SomeService::class)
                        ->onlyMethods(['getDataById'])
                        ->disableOriginalConstructor()
                        ->getMock();

        $apiMock->expects($this->once())
                ->method('getDataById')
                ->willReturn([]);
}

public function testSaveTransactionDataAction(): void
{
        $id = '123';
        $this->setApiMock($id);

        // $this->assertSame(200, something);
}

Thanks
