在茉莉花测试中更改全局变量值 [英] changing global variable values in jasmine test

问题描述

我们在React应用程序中将这样的全局变量用于茉莉花测试批次.

We use global variables like this for a jasmine test batch in our react app.

global.serverVars = {
language: 'en-us',
context: 'testing',

};

在测试不同语言的规范之一中，我想将global.serverVars.language的值更改为nl-nl

In one of the Spec which tests different languages, I want to change value of global.serverVars.language to nl-nl

我不确定如何实现这一目标.任何建议都会有所帮助. 我的意思是，即时更改全局变量值是一种好的做法，还是有更好的方法?

I am not sure how to achieve that. Any suggestion would be helpful. I mean, is it good practice to change global variable values on the fly or there is better approach?

推荐答案

为什么在执行测试用例之前不使用beforeEach或before方法调用全局变量?

Why don't you call your global variable in beforeEach or before Method before executing the test-cases?.

(function() {
  describe('Canvas Actions', function() {
    beforeEach(function () {
       global.serverVars.language: 'nl-nl',
    });
  });
})()
