如何测试一个值是否“大于或等于"?在茉莉花? [英] How can I test that a value is "greater than or equal to" in Jasmine?

问题描述

我想确认一个值是小数(或0)，所以数字应该大于等于0并且小于1.

I want to confirm that a value is a decimal (or 0), so the number should be greater than or equal to zero and less than 1.

describe('percent',function(){  

  it('should be a decimal', function() {

    var percent = insights.percent; 
    expect(percent).toBeGreaterThan(0);
    expect(percent).toBeLessThan(1);

  });

});

如何模仿>= 0"?

推荐答案

你只需要先运行比较操作，然后检查它是否为真.

You just need to run the comparison operation first, and then check if it's truthy.

describe('percent',function(){
  it('should be a decimal',function(){

    var percent = insights.percent;

    expect(percent >= 0).toBeTruthy();
    expect(percent).toBeLessThan(1);

  });   
});
