Testing Dynamic Web Sites
V. Narayan Raman
Tyto Software

Xpath does not query by text well
<div>This is <b>Bold</b></div>
//div[text()=‘This is Bold’] ?
_div(“This is Bold”)
Waits are needed at each step
Explicit waits: Have to code for worst case scenario
Implicit waits: Recover and retry
Tester is forced to understand HTML structures and Javascript nuances.
Common Problems

Proxy based approach
Injects Javascript into browser
Any Javascript enabled browser, any OS
Drives a real browser
Identifies elements smartly
Implicitly waits for AJAX, page loads and timeouts
Sahi – Web Test Automation Tool

//table[@id='listing']/tbody/tr[2]/td[4]/input
//table[@id='listing']/tbody/tr[3]/td[4]/input
Or
_textbox(“q”, _near(_cell("Core Java")))
_textbox(“q”, _near(_cell("Ruby for Rails")))
XPathvs Sahi APIs

Visible properties take precedence
Tests should reflect what the tester sees
Not what the developer wrote
Frames, iframes, layouts are all developer aids to partition information. They need not be visible in tests, though they should be assertable.
Waits are inherent in a web application and should be automatically handled
Sahi Philosophy

Use various visible attributes first
Text, Value, Alt, Title etc.
Allow identification in a context
_checkbox(“x”, _near(_cell(“name”)))
Allow Regular Expression and fuzzy matches
Normalize white spaces across browsers
Automatically look through frames and iframes.
Sahi Identification Strategy

The simplest possible thing
What is not allowed by the Browser Sandbox, delegate to proxy
File Uploads
401 Authentication
File downloads
Browsers may change
Javascript and Proxies are here to stay

Allows recording, debugging and object identification on any browser via injected Javascript
Can add automation on the fly
Even wrap flash/applets etc. when needed
Moving between domains, even accessing multi domains in frames/iframes are possible.

Allows powerful Sahi APIs, normalized across browsers
Allows monitoring of AJAX requests and Frame loads to automatically wait till no activity
Javascript events do not require focus, allowing parallel playback
Injected Javascript
