Testing in Django

Automated testing is an extremely useful bug-killing tool for the modern web developer specifically on Django

Django TestCase

Django’s unit tests use a Python standard library module: unittest. This module defines tests using a class-based approach.

Here is an example which subclasses from django.test.TestCase, which is a subclass of unittest.TestCase that runs each test inside a transaction to provide isolation:

for example

from django.test import TestCase
from .models import Student

# Create your tests here.
class TestStudentModel(TestCase):
    def test_create_student(self):
        student1 = Student.objects.create(first_name="John", last_name="doe", admission_number=1) 
        payload = Student.objects.last()

        # test data
        self.assertEqual(payload.first_name, "John")
        self.assertEqual(payload.last_name, "doe")

When you run your tests, the default behavior of the test utility is to find all the test cases (that is, subclasses of unittest.TestCase)

For more details about unittest, see the Python documentation.

Running The Test

in any file whose name begins with test, automatically build a test suite out of those test cases, and run that suite.

and run with this command

python manage.py test

and you will show the output
