在执行并行执行时，我们如何仅对所有浏览器执行一次查询

Question

我正在使用量角器5.2.2和黄瓜3.2.0。我通过指定如下所示的多重功能来进行并行执行。

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

我只需要对所有浏览器执行一次查询，但是现在该查询正在对每个浏览器执行。当脚本由'protractor命令运行时，如何设置此查询仅执行一次conf.js”。

Answer 1

您可以尝试量角器conf.js的beforeLaunch()。

  /**
   * 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
      }
      ...
  };
