Httprunner的validate

V3支持如下：

例如："eq", "equals", "equal"等都可以表示equal

　　　"lt", "less_than"都代表less_than

def get_uniform_comparator(comparator: Text):
    """ convert comparator alias to uniform name
    """
    if comparator in ["eq", "equals", "equal"]:
        return "equal"
    elif comparator in ["lt", "less_than"]:
        return "less_than"
    elif comparator in ["le", "less_or_equals"]:
        return "less_or_equals"
    elif comparator in ["gt", "greater_than"]:
        return "greater_than"
    elif comparator in ["ge", "greater_or_equals"]:
        return "greater_or_equals"
    elif comparator in ["ne", "not_equal"]:
        return "not_equal"
    elif comparator in ["str_eq", "string_equals"]:
        return "string_equals"
    elif comparator in ["len_eq", "length_equal"]:
        return "length_equal"
    elif comparator in [
        "len_gt",
        "length_greater_than",
    ]:
        return "length_greater_than"
    elif comparator in [
        "len_ge",
        "length_greater_or_equals",
    ]:
        return "length_greater_or_equals"
    elif comparator in ["len_lt", "length_less_than"]:
        return "length_less_than"
    elif comparator in [
        "len_le",
        "length_less_or_equals",
    ]:
        return "length_less_or_equals"
    else:
        return comparator
