如何在另一个特征文件的 javascript 函数中调用我的特征文件函数？

Question

所以我创建了一个如下所示的滚动功能

Feature: Dynamic page scrolling
Scenario: Scrolling function  
* def ScrollHeight = function(){return script("document.body.scrollHeight")
* def ScrollFunction = function(){ script("window.scrollTo(0,document.body.scrollHeight)")
* def ScrollingFunction = 
"""
function(){
var height = ScrollHeight()
while(true)
{ ScrollFunction()
var newHeight = ScrollHeight() 
if(height  === newHeight )
break;
height = newHeight 
} 
}
"""

所以我在我有我的测试场景的同一个功能文件中创建了这个，但我想把它作为一个集中功能到另一个功能文件中，我也可以在其他功能文件中使用它。但我将无法从其他功能文件调用 ScrollHeight 和 ScrollFunction？

这就是我尝试在新功能文件中创建它的方式 Scrolling.feature

Feature: Dynamic page scrolling Function
Scenario: Scrolling function  
*def obj = read('classpath:Testing.feature')
* def ScrollingFunction = 
"""
function(){
var height = obj.ScrollHeight()
while(true)
{ obj.ScrollFunction()
var newHeight = obj.ScrollHeight() 
if(height  === newHeight )
break;
height = newHeight 
} 
}
"""

我的Testing.feature文件看起来像

Feature: Testing
Background:
* def ScrollHeight = function(){return script("document.body.scrollHeight")
* def ScrollFunction = function(){ 
script("window.scrollTo(0,document.body.scrollHeight)")}
Scenario: Test-1
* def fun = call read('classpath:Scrolling.feature')
* call fun.ScrollingFunction

但是对我不起作用

Answer 1

script()等所有方法只有在默认实例化driver后才可用。因此，请确保在 driver <url> 步骤之后 声明任何 re-usable 函数。

否则你必须为 re-usability 做这样的事情：

* def getScrollHeight = """ function() { var driver = karate.get('driver'); return driver.script("document.body.scrollHeight"); } """

如果这不起作用，请创建一个快速入门示例，以便我们研究它：https://github.com/intuit/karate/tree/develop/examples/ui-test

Answer 2

您不需要引用其他函数。它可以在同一个脚本中完成。

这对我有用：

Feature: Search Posts

  Background:
    * configure driver = { type: 'chrome', start: false }

    # build search endpoint
    * def buildSearch =
      """
      function() {
        var keys = 'fake%20news';
        var filter = 'eyJycF9jcmVhdGlvbl90aW1lIjoie1wibmFtZVwiOlwiY3JlYXRpb25fdGltZVwiLFwiYX'+
                     'Jnc1wiOlwie1xcXCJzdGFydF95ZWFyXFxcIjpcXFwiMjAyMFxcXCIsXFxcInN0YXJ0X21v'+
                     'bnRoXFxcIjpcXFwiMjAyMC0xXFxcIixcXFwiZW5kX3llYXJcXFwiOlxcXCIyMDIwXFxcIi'+
                     'xcXFwiZW5kX21vbnRoXFxcIjpcXFwiMjAyMC0xMlxcXCIsXFxcInN0YXJ0X2RheVxcXCI6'+
                     'XFxcIjIwMjAtOC0xMlxcXCIsXFxcImVuZF9kYXlcXFwiOlxcXCIyMDIwLTgtMTJcXFwifVwifSJ9';
        
        return 'https://m.facebook.com/search/posts/?q='+keys+'&epa=FILTERS&filters='+filter;
      }
      """

  Scenario: facebook search

    # Scroll down until no more pager
    # return null to keep looping
    * def fecthPage =
      """
      function() {
        var results = script("window.scrollTo(0, document.body.scrollHeight); document.querySelectorAll('#see_more_pager').length")
        return results == 0 ? results : null;
      }
      """

    # Print Post information
    * def permalinks = []
    * def getPost =
      """
      function(x, y, z) {
        var feat = x.script("_.getAttribute('data-ft');");
        var store = x.script("_.getAttribute('data-store');");
        if (feat && store) {
            feat = karate.toJson(feat);
            store = karate.toJson(store);
            karate.appendTo(permalinks, {'Features': feat, 'Store': store});
        }
      }
      """

    Given driver buildSearch()

    * waitUntil(fecthPage)
    * def posts = locateAll('//div[@data-store][@data-ft]')
    * karate.forEach(posts, getPost)
    * print "Posts:", permalinks

为了避免 chrome 配置文件占用我的所有磁盘，我在空手道之前启动它。
这就是为什么 start: false
