What is Selenium?

Automates browser

Testing feature(element assertion, etc)

Selenium IDEsupported on Firefox

Other browsers are supported for testing

UI Testing

Logic testing doesn’t cover UI

Web application’s UI is browsers

It’s not easy to testing with browsers

With Selenium

Testable with Browsers

Test cases can be written in:Java, C#, Ruby, Python, etc

Using CI,UI becomes testable continuously

Architecture

Selenium 2.0

WebDriver

A driver, which is run by a Client Driver

Client Driver

Test drivers, implemented in some languages (Java, C#, Python, etc)

Architecture

Browser

WebDriverplugin

Client Driver( library )

Selenium IDE

Drive a browser directly from a client

Get Selenium IDEAll plugins installed at once

Got Selenium IDE

Now you can run Selenium IDE

Recording Mode

Selenium IDE has a recording mode

Recording mode:ON

Recording mode:OFF

Be Careful

If recording mode on:

All actions recorded automatically

May be an accident,if the mode is on by mistake

Otherwise:

No actions recorded automatically

Let’s Record

To record, turn on the recording mode

You only do browsing,same as when you browse normally

Demonstration

Twitter login/tweet/logout test

01. recording

02. fail with missing element

03. fix the element

04. captcha error

05. mostly success, except tweeting

To JUnit Test Case

It’s easy to convert to JUnit Test Case, or other formats.

Enable the feature,[Options]-[Options]-[Enable experimental features]

To convert,[Options]-[Format]-[What a format you want]

GotJUnit Test Case

As a result:

Other Ways

Copy directly to clipboard:[Options]-[Clipboard Format]-[What a format you want]

Export as a file:[File]-[Export Test Case As...]-[What a format you want]

Architecture Comparison

It takes about a minute to run test

As I investigated,class loading is a little slow

Browser

Client Driver( library )

Selenium IDE

Architecture Comparison

Required that the server is ready

It takes rather a half time than without the server

Conclusion

UI testing is complex,so the maintenance is not easy

Suggest that test the critical patterns

Login/Logout, and any othervery important features

Powerful to prevent the regression
