TestCase inconsistent behavior on Db integrity error

[an-mile]

Hello! I'm filing my first Django bug and hopefully it is meaningful:

When a db integrity error occurs in some test, the exception is captured by the test suite and following code in the test is executed. This seems inconsistent with any other exception that might arise from test code execution.
It might be similar to the closed ticket https://code.djangoproject.com/ticket/14223

models.py:

from django.db import models

# inspired by https://code.djangoproject.com/ticket/14223

class Reporter(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    email = models.EmailField(null=True)

    def __unicode__(self):
        return u"%s %s" % (self.first_name, self.last_name)

class Article(models.Model):
    reporter = models.ForeignKey(Reporter, on_delete=models.CASCADE,)
    headline = models.CharField(max_length=100)

tests.py:

from django.test import TestCase

from mod.models import Reporter, Article


class DatabasePsycopgTest(TestCase):

    def test_db_integrity_error_handling(self):
        objs = [Article(reporter_id=123, headline='Hello DB integrity')]
        # NammeErrorWouldRaiseHere
        Article.objects.bulk_create(objs)  # DB Integrity Error captured...
        print('Hello Dear Django Coders!') 
        self.assertEqual(1, 2) 

Here we get following traceback:

Traceback (most recent call last):
  File "/..../python3.9/site-packages/django/test/testcases.py", line 299, in _setup_and_call
    self._post_teardown()

  File "/..../codelab/dabase/mod/tests.py", line 12, in test_db_integrity_error_handling

AssertionError: 1 != 2

[Edit: It will also print "Hello Dear Django Coders!"]. But when uncommenting the "NammeErrorWouldRaiseHere" , "Hello Dear Django Coders!'" is not printed, nor is the last "AssertionError" executed. This seems confusing and inconsistent behavior.

It appears on SQLite as well as with PsycoPg / PG. Furthermore, the exception can not be captured within the Code with a regular try-except. Following modification of the test will not print "Hello" :

        try:
            Article.objects.bulk_create(objs)
        except Exception:
            print('Hello')
