        $this->calculationPeriod = new CalculationPeriod();
        //EntityManagerInterface $entityManager;

    public function testCalculatesPassForAllPassingScores()

        $entityManager = $this->getMockBuilder(EntityManagerInterface::class)->getMock();
        $slaid = 18;  
        $slaScore = $entityManager->getRepository('AppBundle:Sla')->findById($slaid);
        $dataProvider = $this->dataProviderFactory->create($slaScore->getSla());
        $score = $this->calculationMethod->calculateScore($dataProvider, $slaScore, $this->calculationPeriod);
        $this->assertEquals("PASS", $score->getTextValue());
    }

private function generateScore(int $slaId, bool $hasPassed)
    {
        $sla = new Sla();
        $reflection = new \ReflectionClass($sla);
        $property = $reflection->getProperty('id');
        $property->setAccessible(true);
        $property->setValue($sla, $slaId);
        $sla->setTargetMinimum(80);
        $sla->setTargetExpected(90);
        $slaScore = new SlaScore($sla, $this->calculationPeriod);
        $slaScore->setValue($hasPassed ? 95 : 70); 
        return $slaScore;
    }
}
?>

I am getting the error as command

phpunit --filter testCalculatesPassForAllPassingScores

PHP Fatal error:Uncaught Error: Call to a member function findById() on null.

I am running this testcase but I am getting this error How to resolve this problem can you help me to resolve this issue?

The error message is pretty clear, you are calling the findById() method from a null value instead of a Repository instance.

Given your code, in my opinion you should replace the line below

$slaScore = $entityManager->getRepository('AppBundle:Sla')->findById($slaid);

by this

$slaScore = $entityManager->getRepository(Sla::class)->findById($slaid);
