如何在 Django 的单元测试驱动程序中测试表单的验证逻辑？

发布于 2024-08-20 11:00:02 字数 306 浏览 4 评论 0原文

我想测试表单验证逻辑的 is_valid 部分。在我的测试驱动程序中，我有：

  test_animal = Animal(name="cat", number_paws="4")
  test_animal_form = AnimalForm(instance=test_animal)
  assertEqual(test_animal_form.is_valid(), True)

断言失败，但从我看来，表单中不应该有任何错误。我在表单中没有看到任何验证错误。如果 test_animal 实例在加载到表单中时应该验证，那么这是否可以作为测试用例？

I want to test the is_valid portion of a form's validation logic. In my test driver I have:

  test_animal = Animal(name="cat", number_paws="4")
  test_animal_form = AnimalForm(instance=test_animal)
  assertEqual(test_animal_form.is_valid(), True)

The assertion fails, but from what I see there shouldn't be any errors in the form. I don't see any validation errors in the form. Should this work as a test case if the test_animal instance when loaded into the form should validate?

您看到验证错误的原因是验证中未使用实例数据，您必须指定发送到表单的数据。

test_animal = Animal(name="cat", number_paws="4")
test_animal_form = AnimalForm(instance=test_animal)
assertEqual(test_animal_form.is_valid(), False) # No data has been supplied yet.
test_animal_form = AnimalForm({'name': "cat", 'number_paws': 4, }, instance=test_animal)
assertEqual(test_animal_form.is_valid(), True) # Now that you have given it data, it can validate.

The reason you're seeing the validation errors is because instance data isn't used in validation, you have to specify the data being sent to the form.

test_animal = Animal(name="cat", number_paws="4")
test_animal_form = AnimalForm(instance=test_animal)
assertEqual(test_animal_form.is_valid(), False) # No data has been supplied yet.
test_animal_form = AnimalForm({'name': "cat", 'number_paws': 4, }, instance=test_animal)
assertEqual(test_animal_form.is_valid(), True) # Now that you have given it data, it can validate.
