用 Jasmine 检查两个边界(在匹配器之间)

问题描述

在 Jasmine 中，有 toBeGreaterThan 和 toBeLessThan 匹配器.

In Jasmine, there are toBeGreaterThan and toBeLessThan matchers.

如果我想检查特定范围内的整数值怎么办?有没有类似 toBeInBetween 匹配器的东西?

What if I want to check an integer value in a specific range? Is there anything like toBeInBetween matcher?

目前，我可以通过两个单独的 expect 调用来解决它:

Currently, I can solve it in two separate expect calls:

var x = 3;

expect(x).toBeGreaterThan(1);
expect(x).toBeLessThan(10);

推荐答案

您可以运行布尔比较并断言结果为true:

You can run the boolean comparison and assert the result is true:

expect(x > 1 && x < 10).toBeTruthy();

此外，还有由 jasmine 引入的 toBeWithinRange() 自定义匹配器-匹配器:

Also, there is toBeWithinRange() custom matcher introduced by jasmine-matchers:

expect(x).toBeWithinRange(2, 9);  // range borders are included
