初试appcrawler的问题

yangyang · 2020 年11 月 12 日 07:39

在极客时间上学习了思寒老师的appcrawler，添加blackList之后，运行appcrawler时会报错，想问下定义blackList的标准格式。
1，yaml配置文件：

urlWhiteList: []
blackList: 
  //*[@resource-id='com.aibs:id/action_bar_root']
beforeRestart: []

报错信息：

2，参考appcrawler-1.4.0.pdf 定义blacklist

urlWhiteList: []

blackList: ["微信", "客服"]

beforeRestart: []

你的文件格式不对。不是标准的yaml格式吧

yangyang · 2020 年11 月 13 日 03:40

谢谢老师，是的，后来找了yaml线上检查看了一下，格式不对。找到了最新的教程https://blog.csdn.net/weixin_46635091/article/details/105841147，学习了一下。
还有一些疑问：
1，文中提到：“遍历原则：它的遍历原则是，找页面的里层次最深的元素，也就是处于中心位置元素会被优先遍历”，如果有弹窗在主页面的上面，我想先去遍历这个弹窗，如何设置让appcrawler能先遍历前面的页面么？现在看到的现象是appcrawler先遍历了后面的主页。

2，testcase可以支持多个case么？我写成了下面的格式，会报错：
YAML：
testcase:

name: “Log in as gust”
steps:
- xpath: //[contains(@text, ‘游客’)]
  action: click
  then: ["//[contains(@text, ‘测试fail’)]"]
name: “Swipe at main page”
steps:
- xpath: //*
  action: driver.swipe(0.5, 0.8, 0.5, 0.2)
  then: ["//*[contains(@text, ‘推荐视频’)]"]
  错误信息：
  Exception in thread “main” com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of com.testerhome.appcrawler.ReactTestCase out of START_ARRAY token

at [Source: (StringReader); line: 29, column: 3] (through reference chain: com.testerhome.appcrawler.CrawlerConf[“testcase”])
问题：如何写配置可以支持多个testcase？

当遇到webview的时候，除了App打开webview的debug开关，配置文件的capibilty打开autoWebview，还需要做什么配置么？在定位webview的页面时，定位规则和原生App一样么？
