断言整数在范围内 [英] Assert an integer is within range

问题描述

我正在用 python 编写一些单元测试来测试我是否收到一个整数.然而，有时这个整数可能会相差 1 或 2，我并不在乎.本质上，我希望能够断言接收到的整数在某个范围内，例如:

I am writing some unittests in python that are testing if I receive an integer. However sometimes this integer can be off by 1 or 2 and I don't really care. Essentially I want to be able to assert that the received integer is within a certain range, something like:

self.assertBetween(998, 1000, my_integer)

是否有一种可接受的方式来做到这一点?或者我必须做这样的事情:

Is there an accepted way of doing this? Or will I have to do something like this:

self.assertTrue(998 <= my_integer)
self.assertTrue(my_integer <= 1000)

编辑到目前为止的答案表明:

EDIT The answers so far suggest:

self.assertTrue(998 <= my_integer <= 1000)

与我的带有 2 个断言的示例相比，这有什么好处吗?

Is there any benefit of this over my example with 2 asserts?

推荐答案

您可以使用 "链式比较":

self.assertTrue(998 <= my_integer <= 1000)
