我们如何在并行执行时对所有浏览器只执行一次查询

Question

我正在使用 Protractor 5.2.2 和 Cucumber 3.2。0.I 正在通过指定下面给出的多重功能进行并行执行。

multiCapabilities: [
{
browserName: 'chrome',
},
{
browserName: 'chrome',
}],

我只需要为所有 browsers.But 执行一次查询，现在正在为每个 browsers.How 执行查询，我可以将此查询设置为仅在脚本运行时执行一次吗运行通过命令 'protractor conf.js'.

Answer 1

你可以试试量角器beforeLaunch()conf.js。

  /**
   * A callback function called once configs are read but before any
   * environment setup. This will only run once, and before onPrepare.
   *
   * You can specify a file containing code to run by setting beforeLaunch to
   * the filename string.
   *
   * At this point, global variable 'protractor' object will NOT be set up,
   * and globals from the test framework will NOT be available. The main
   * purpose of this function should be to bring up test dependencies.
   */
  beforeLaunch?: () => void;

conf.js

  exports.config = {

      multiCapabilities: [],          

      specs:[],

      beforeLaunch: function(){
           // execute query at here
      }
      ...
  };

我们如何在并行执行时对所有浏览器只执行一次查询

How can we execute a query only one time for all browsers while doing parallel execution

cucumber

protractor
