1. Introduction

This document is an attempt to build a Data Driven Test Automation Frameworkwith functional decomposition approach which can be used across different web based applications. The main advantage of using this tool is its open source software & support multiple browsers & platforms.

2. Framework Structure

The framework consists of the following components. Function Library Object Repository Test Run Parameter File Test Data Application Scenario Files(Test Cases) Driver Script

The directory structure in which these components are arranged is as shown below.

2.1 Function Library

In this approach, all the coding logic is in the form of user defined ‘Java’ script functions.All of these functions are stored in function libraries (.java file). While developing scripts for an application, the end user would make use of these functions from driver script. All the function library files (.java files) are kept in the folder which is kept parallel to ‘src’ folder which contains the driver script.

2.2 Object Repository

Each application automated has a different object repository file and there is only one object repository for each application. All the object repository files (.xls file) are kept in the ‘Test Objects’ in the directory structure. This makes the maintenance of the script easy as we just need to update this excel sheet in case the objects are modified in future.As we can see in the screen shot attached below of the sample object repository file which consists of the Test Case ids and corresponding objects for particular test case. So in the application if some objects are modified then we just need to update in this excel sheet and not in entire suite for different scripts which uses this value.

2.3 Test Run Parameter File

‘Test Run Parameter File’ is a like configuration file which contains information required to do the initialization settings to the Driver selenium script for a particular application. The ‘Test Run Parameter File’ is in the form of a spreadsheet which has an entry for each application and settings data such as Project Code, Project Name, Test Suite Name, Test Description, Browser options, Selenium server address, Selenium port number, Base url and Test results paths.

2.4 Test Data

All the test data is stored in excel sheet. We are using data driven framework along with functional decomposition approach. The test data excel sheet consists of the unique test case id and the flag to run that case in the test suite. The excel sheet might have 100 sets of data, but the user might want to execute only 10 of them. The flag to run the test case helps in this situation by providing the user with the option to select only certain sets of data by choosing the option as YES or NO.

2.5 Application Scenario Files (Test Cases)

All the test cases are stored in excel sheet. The ‘Req. ID/ FS. Ref.’ column is used as reference in the test data and object repository excel sheets. While executing a particular test case scenario all the test steps are executed and the actual results are compared with the expected results. And based on that the final output is generated whether a particular test case is ‘Passed’ or ‘Failed’.In the following diagram the test case ids (ESR4, ESR6 and so on) used in the test data and object repository excel sheets can be seen in ‘Req. ID/ FS. Ref.’ column.

2.6 Driver Script

Driver script is a selenium test script which drives the script execution. This test script calls the individual test scripts which reads the parameters from the test data excel sheet and makes calls to appropriate functions in the function library.

3. Conclusion

So this is a full fledge functional automation framework using open source tool. The creation of the script initially is little time consuming but in the long run, the time spent will be useful during the regression phase. In order to keep up with the pace of product development and delivery, it is essential to implement effective, reusable test automation. The Open Source Test Automation Framework provides a way to drive productivity and foster code reuse — ultimately enhancing the quality of resulting software.
