匹配Chai断言中的部分对象？ [英] Match partial objects in Chai assertions?

问题描述

我正在寻找匹配以下内容的最佳方法：

I am looking for the best way to match the following:

expect([
    {
        C1: 'xxx',
        C0: 'this causes it not to match.'
    }
]).to.deep.include.members([
    {
        C1: 'xxx'
    }
]);

以上操作无效，因为C0存在于实际中，而不是预期中。简而言之，我希望通过PASS，但是我不确定如何在不编写大量自定义代码的情况下完成此操作...

The above doesn't work because C0 exists in the actual, but not the expected. In short, I want this expect to PASS, but I'm not sure how to do it without writing a bunch of custom code...

推荐答案

chai-subset 或 chai-fuzzy 可能还会执行您要查找的内容。

chai-subset or chai-fuzzy might also perform what you're looking for.

Chai-subset应该像这样工作：

Chai-subset should work like this:

expect([
  {
    C1: 'xxx',
    C0: 'this causes it not to match.'
  }
]).to.containSubset([{C1: 'xxx'}]);

如果我不想包含其他插件，我个人会使用财物包括的财产或键匹配器：

Personally if I don't want to include another plugin I will use the property or keys matchers that chai includes:

([
  {
    C1: 'xxx',
    C0: 'this causes it not to match.'
  }
]).forEach(obj => {
  expect(obj).to.have.key('C1'); // or...
  expect(obj).to.have.property('C1', 'xxx');
});
