在单元测试中有多个断言是不好的做法吗？

# Test function for function A
def test_function_a():
    assert function_a() == "expected_result"

# Test function for function B
def test_function_b():
    assert function_b() == "another_expected_result"

# Test function for function A with different input
def test_function_a_with_different_input():
    assert function_a(input_data) == "unexpected_result"
