Capture page response time and Script Reuse

Often we want to know page response time under load? In LoadWise, it is quite easy to do so.

Example

This following load test script will try to

Sign in http://agiletravel.herokuapp.com
Select flight (arrival and departure city)
Sign off

To capture page response time for 'Sign in' and 'Flight selection', we just need to add log_time around page submit operation.

require File.join(AGILEWAY_APP_ROOT, "lib", "rwebspec-mechanize", "rwebspec-mechanize.rb")

describe "Select Flight" do
  include RWebSpec::Mechanize::LoadTestHelper

  it "Sign in, Select Flight, Sign off" do
    stats = run_with_virtual_users() {
      browser = open_browser
      log_time("Open home page") { browser.goto_page("/") }
      browser.enter_text("username", "agileway")
      browser.enter_text("password", "test")
      log_time("Sign in") { browser.click_button("Sign in") }

      browser.click_radio_option("tripType", "oneway")
      browser.select_option("fromPort", "New York")
      browser.select_option("toPort", "Sydney")
      log_time("Select Flight") { browser.click_button("Continue") }
      assert browser.text.include?("Passenger Details")

      log_time("Sign off") { browser.click_link("Sign off") }
      assert browser.text.include?("Login")
    }
  end

end

Output like below:
