Question

我正在使用CasperJS 1.1并且我想模拟单击文件字段，但是当我运行测试时（项目使用AngularJS fwiw）我收到错误：

# Create gallery page
PASS File field exists
FAIL Cannot dispatch mousedown event on nonexistent selector: input#gallery_file_0
#    type: uncaughtError
#    file: spec/javascripts/casperjs/create_gallery.coffee:1323
#    error: Cannot dispatch mousedown event on nonexistent selector: input#gallery_file_0
#           CasperError: Cannot dispatch mousedown event on nonexistent selector: input#gallery_file_0
#               at mouseEvent (/usr/local/Cellar/casperjs/1/libexec/modules/casper.js:1323)
#               at click (/usr/local/Cellar/casperjs/1/libexec/modules/casper.js:428)
#               at spec/javascripts/casperjs/create_gallery.coffee:7
#               at runStep (/usr/local/Cellar/casperjs/1/libexec/modules/casper.js:1523)
#               at checkStep (/usr/local/Cellar/casperjs/1/libexec/modules/casper.js:368)
#    stack: not provided

这个错误对我来说没有意义，因为我之前关于输入字段存在的断言实际上是正确的。这是测试文件：

casper.test.begin "Create gallery page", 1, (test) ->

  casper.start "http://localhost:3000/galleries/new", ->

    @then ->
      test.assertField("input#gallery_file_0", null, "File field exists")
      @click("input#gallery_file_0")


  casper.run()

可能是什么问题？

版本：

casperjs --version
1.1.0-DEV

phantomjs -v
1.9.1

MacOSX 10.8.4

使用以下行，看起来好像是在检查字段的值是否为null，当字段不存在时，该值似乎为真。

test.assertField("input#gallery_file_0", null, "File field exists")

相反，您应该使用：

test.assertExists("input#gallery_file_0", "File field exists");

CasperJS click（）无法调度mousedown事件错误
