以下是一种不使用OR运算符进行相同条件测试的解决方法：

# 使用AND运算符进行相同条件测试
def test_condition(a, b):
    if a == "condition" and b == "condition":
        print("Both conditions are true")
    else:
        print("At least one condition is false")

# 示例测试
test_condition("condition", "condition")  # 输出: Both conditions are true
test_condition("condition", "not condition")  # 输出: At least one condition is false
test_condition("not condition", "condition")  # 输出: At least one condition is false
test_condition("not condition", "not condition")  # 输出: At least one condition is false

在上述示例中，我们使用AND运算符来检查两个条件是否都为True。如果两个条件都为True，则输出"Both conditions are true"，否则输出"At least one condition is false"。

这种方法的原理是，AND运算符只在两个条件都为True时返回True，所以我们可以根据这个特性来判断是否满足相同条件测试。
