AssetError Bound Method in unit test

Question

Currently, I am creating a test script. but I am getting this error:

 <bound method Score.percentage of <Score: Score object>> != 100

these are my codes:

models.py

class Score(models.Model):


    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    Name = models.CharField(max_length=120)
    score = models.FloatField(null=True, default=0)

    def percentage(self):

        percentage = (score/50) * 100

        return percentage

This is my test script (test.py)

self.assertEqual(Score.percentage, 100)

I am expecting:

Score.percentage = 100

but I got

 <bound method Score.percentage of <Score: Score object>> != 100

Answer 1

Percentage is a method so you need to call it

self.assertEqual(Score.percentage, 100)

should be

self.assertEqual(Score.percentage(), 100)

Note: it still won't work correctly though since you need to call the method on an instance of score, and call the instances score ( self.score ) inside of the method instead of score.
