Reason for reading this research ? Web applications

Become an essential part of many business strategies

Highly competitive environment Frequent changes Frequent customer’s feedbacksShort deadlines Highly customized Incremental deliverables

4

IntroductionAgile software development processes

Test-Driven Development (TDD) Drawback : tests are only written by the developer

Acceptance Test-Driven Development (ATDD)

Acceptance tests written by the customer

Understanding exactly what customers want

5

Related Work A Web Testing Model - by Qianet al

A web application is defined in a PFD (Page Flow Diagram)Then converted into a PTT (Page Test Tree)

6

Related Work Test case skeletons derived from tree paths

7

Related Work The ATTD current approaches and tools Difficult to use Need to learn new programming language Bad interface

8

The goal of this approach1. Graphical interface

2. Assist developers to automatically generate acceptance tests

3. Supply a communication interface between the customer and the development team

4. Automatically execute acceptance test cases

The Approach

10

Tools Suite Two tools are both open source

AcceptLink : Correspond to a web application developed in PHP and Java steps 1 to 5

AWTAF (Automated Web Test Application Framework) : Automate web functional tests execution using Selenium RC,

HttpUnit or HtmlUnit step 6

Step 1

13

Step 2 Each user story is mapped into a graph

Based on Qian’s work removes the existing

cycles generates a test tree

14

Steps 3 and 4 All the testing scenarios generated are displayed

the customer and developers discusses and validates

If the customer considers a particular scenario correct inform the inputs and expected results

If not steps 1, 2 and 3 have to be do again until the customer considers

it correct.

15

Step 5 Finally Testing scenarios are

converted into automated test scripts

16

Step 6 Then Use AWTAF tool to run the automated acceptance test case

modeled

17

Conclusions This paper described an approach to assist the ATDD use in web applications.

In comparison to current ATTD tools supporting customer-developement team communication test scenario selection using a summary graph

New features allowing to test AJAX features are under studyFurther experiments are planned
