Code Review

This pull request significantly expands the unit test coverage for various dataset loaders, postprocessors, and evaluators, including AIME (2024, 2025, 2026), DAPO Math, GPQA, GSM8K, MATH, and RealworldQA. The review feedback focuses on improving test quality and consistency: it suggests using new_callable=mock_open directly in @patch decorators to simplify file mocking, avoiding __new__ to bypass initialization in tests, inheriting from unittest.TestCase in test_dapo_math.py for consistency, and moving inline imports of AISBenchDataContentError to the top of the files.

Using new_callable=mock_open directly in the @patch decorator is cleaner and avoids manual assignment of mock_open_file.return_value = m.return_value.

Suggested change

	@patch("builtins.open")
	def test_aime2026_load(self, mock_open_file, mock_get_path):
	line = '{"question": "What is 1+1?", "answer": "2"}'
	m = mock_open(read_data=line + "\n")
	mock_open_file.return_value = m.return_value
	@patch("builtins.open", new_callable=mock_open, read_data='{"question": "What is 1+1?", "answer": "2"}\n')

Using __new__ to bypass __init__ is generally considered a code smell in unit tests. Since _get_dataset_class is a method that does not access self, you can call it directly on the class by passing None as self.

Suggested change

	def test_aime2025_jdg_dataset_class(self):
	instance = Aime2025JDGDataset.__new__(Aime2025JDGDataset)
	result = instance._get_dataset_class()
	self.assertIs(result, Aime2025Dataset)
	def test_aime2025_jdg_dataset_class(self):
	result = Aime2025JDGDataset._get_dataset_class(None)
	self.assertIs(result, Aime2025Dataset)

For consistency with the rest of the test suite (which all use unittest.TestCase), consider inheriting from unittest.TestCase and using self.assert* methods instead of plain assert statements.

Please move the import of AISBenchDataContentError to the top of the file to avoid redundant inline imports across multiple test methods.
