Selenium 网页测试工具和perl脚本结合，我自己记录的学习过程

 

很有意思的一点是那个 “Selenium Remote Contrtol ” 自己是像 一个http代理服务器一样的在机器上运行的，所以他可以模拟一个假的网页出来，由他启动的浏览器 地址栏显示的是www.google.com，但其实显示的经过他自己处理之后的东西了，不是google的网页来的。详细见http://selenium-rc.openqa.org/tutorial.html

(1) download Selenium IDE,a Firefox addon
=======================
    http://release.openqa.org/selenium-ide/1.0-beta-2/selenium-ide-1.0-beta-2.xpi
  
     After download this file, click "open file" menu in firefox, firefox will inform you to
install this plugin. When installation is complete , you can find a "Selenium IDE" item in
"tool" menu . click it will run the Selenium IDE.

see more details on http://wiki.openqa.org/display/SIDE/Home .

(2)use Selenium IDE to record a testcase.   open webpage "http://www.google.com/" ,
=======================
click "start record" buttion in Selenium IDE, manually did some operations in the browser,then click "stop record " button in Selenium IDE. clicke "save testcase" menu to save the testcase
into a html file. click "file" -> "export testcase as "-> "Perl Selenium RC" , save the testcase into a
file testcase1.pl .

(3)Download Selenium Remote Control
=====================
http://archiva.openqa.org/repository/releases/org/openqa/selenium/selenium-remote-control/1.0-beta-1/selenium-remote-control-1.0-beta-1-dist.zip

extract it into directory "selenium-remote-control-1.0-beta-1".

cd to "selenium-remote-control-1.0-beta-1\selenium-server-1.0-beta-1"

now let's start the selenium server, see instructions on http://selenium-rc.openqa.org/tutorial.html.

-----------------------------------
1. requires the Java Runtime Environment (JRE) version 1.5.0 or higher

-------------------------------------------------
2. start server in "interactive mode" . options descriptiosn can be found here http://selenium-rc.openqa.org/options.html.
use command "java -jar selenium-server.jar -interactive"

It looks like it dosen't work with my firefox3.
After searching in Selenium wiki(http://wiki.openqa.org/display/SRC/Home),
the "Firefox refused shutdown while preparing a profile" problem is a frequently asked question.
It seems to be a bug of this verison. So I download the "latest nightly build" one
( http://release.openqa.org/cgi-bin/selenium-remote-control-redirect.zip),
and try again, it worked this time.

4) Try the exported perl script .
============================
On my computer ,there are two modules are required which were not supplied in the Selenium package.
it is "Test::Exception.pm " and "Sub::Uplevel.pm".
we can download it from http://search.cpan.org/, place them in the "perl lib" directory which other Selenium perl libs in.
--------------------
Added this into “testcase.pl” , so it can find our lib.

use FindBin qw($Bin);
use lib "$Bin/selenium-remote-control-1.0-SNAPSHOT/selenium-perl-client-driver-1.0-SNAPSHOT/lib";
-----------------------------
Now the script becomes:
use strict;
use warnings;

use FindBin qw($Bin);

use lib "$Bin/selenium-remote-control-1.0-SNAPSHOT/selenium-perl-client-driver-1.0-SNAPSHOT/lib";

use Time::HiRes qw(sleep);
use Test::WWW::Selenium;
use Test::More "no_plan";
use Test::Exception;

my $sel = Test::WWW::Selenium->new( host => "localhost",
                                    port => 4444,
                                    browser => "*chrome",
                                    browser_url => "http://www.google.cn/" );

$sel->open_ok("/");
$sel->type_ok("q", "widebright");
$sel->click_ok("btnG");
$sel->wait_for_page_to_load_ok("30000");
$sel->is_text_present_ok("widebright个人空间");
$sel->click_ok("link=widebright的个人空间?);

--------------------------------------------
run this perl script ,
D:\Selenium>perl testcase1.pl

正常的话，可以看到脚本正常运行，同时firefox浏览器会被启动在进行交互操作。

*Selenium Core (http://selenium-core.openqa.org/)

   Selenium Core is a test tool for web applications. Selenium Core tests run directly in a browser, just as real users do. And they run in Internet Explorer, Mozilla and Firefox on Windows, Linux, and Macintosh. No other test tool covers such a wide array of platforms.

*Selenium Grid (http://selenium-grid.openqa.org/)
Selenium Grid is a tool that dramatically speeds up functional testing of web-apps by leveraging your existing computing infrastructure. It allows you to easily run multiple tests in parallel, on multiple machines, in an heterogeneous enviroment.
