为[0,0]和返回空数组时失败

我试着用那个测试来测试功能,顺便说一句,它总是失败的:

[0, 0] should equal []

有人能告诉我我的错误在哪里吗?

测验:

Test.describe("Basic tests")

Test.assert_equals(count_positives_sum_negatives([1, 2, 3, 4, 5, 6, 7,
8, 9, 10, -11, -12, -13, -14, -15]),[10,-65])

Test.assert_equals(count_positives_sum_negatives([0, 2, 3, 0, 5, 6, 7,
8, 9, 10, -11, -12, -13, -14]),[8,-50])

Test.assert_equals(count_positives_sum_negatives([1]),[1,0])

Test.assert_equals(count_positives_sum_negatives([-1]),[0,-1])

Test.assert_equals(count_positives_sum_negatives([0,0,0,0,0,0,0,0,0]),[0,0])

Test.assert_equals(count_positives_sum_negatives([]),[])

我的代码:

def count_positives_sum_negatives(arr):
    positive_count = 0
    negative_sum = 0
    for n in arr:
        if n > 0:
            positive_count += 1
        elif n < 0:
            negative_sum += n

    return [positive_count, negative_sum]
