Watir Page性能功能可让您跟踪响应时间指标，并且在Chrome，Firefox，IE9及更高版本中运行良好。 Safari浏览器目前不支持。

让我们仔细看看如何使用此功能。要使用它，我们需要使用gem安装watir-performance，如下所示-

命令

gem install watir-performance

瓦特性能

我们已经完成了watir-performance的安装。支持的指标是-

  • 概要
  • 导航
  • 记忆
  • 定时

这里讨论了一个使用watir性能的工作示例。在这里，我们将检查网站的响应时间-www.tutorialspoint.com ，如下所示-

require 'watir'
require 'watir-performance'
10.times do
   b = Watir::Browser.new :chrome
   b.goto 'https://www.tutorialspoint.com'
   load_secs = b.performance.summary[:response_time] / 1000
   puts "Load Time: #{load_secs} seconds."
   b.close
end

输出

Load Time: 7 seconds.
Load Time: 7 seconds.
Load Time: 5 seconds.
Load Time: 5 seconds.
Load Time: 6 seconds.
Load Time: 5 seconds.
Load Time: 5 seconds.
Load Time: 13 seconds.
Load Time: 12 seconds.
Load Time: 5 seconds.

使用Performance.timing

require 'watir'
require 'watir-performance'

b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
load_secs = b.performance.timing[:response_end] - b.performance.timing[:response_start]
puts "Time taken to respond is #{load_secs} seconds."
b.close

输出

Time taken to respond is 41 seconds.

使用性能导航

require 'watir'
require 'watir-performance'

b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
perf_nav = b.performance.navigation
puts "#{perf_nav}"
b.close

输出

{:type_back_forward=>2, :type_navigate=>0, :type_reload=>1, 
:type_reserved=>255, :redirect_count=>0, :to_json=>{}, :type=>0}

使用Performance.memory

require 'watir'
require 'watir-performance'

b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
memory_used = b.performance.memory
puts "#{memory_used}"
b.close

输出

{:js_heap_size_limit=>2, :type_navigate=>0, :type_reload=>1, :ty2136997888, 
:total_js_heap_size=>2, :type_navigate=>0, :type_reload=>1, :ty12990756, 
:used_js_heap_size=>2, :type_navigate=>0, :type_reload=>1, :ty7127092}
