使用Jasmine检查两个边界（在匹配器之间） [英] Checking two boundaries with Jasmine (between matcher)

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？有什么像 toBeInBetween matcher？

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

目前，我可以在两个单独的中解决它期待来电：

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

你可以运行布尔比较并断言结果是 true ：

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

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

此外，还有 toBeWithinRange（）自定义matcher由 jasmine-matchers 介绍：

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

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