AUTOMATION TESTING


3/24

STEPS INVOLVED IN APPROACH FOR TEST AUTOMATION

Requirement gathering from the client

Understanding and Analyzing the Requirement

Grouping the requirement into Test cases

Preparing the Design for Automation

Building Scripts depending on the Design

Review of Scripts at Offshore Delivery to the Client


4/24

Identification of Test Cases for Automation

Identification of Common Functionality and coding Standards, Naming

Conventions & Templates

Building the Re-Usable Library for example:

Application Login, Logout, Common Functionality Related code etc

Tool & Application Settings, Restoring, Object Repository, Recovery, House

Keeping etc

Error handling, Log Reporting, messaging etc

Script Development and deliver after Verification & Validation

DESIGN STEPS OF THE APPROACH FOR TEST AUTOMATION

BENEFITS OF AUTOMATION TESTING

Speed up Test Execution: In less span of time can run more no of testscripts which reduces the time and speeds up the execution task.

Achieved Improved Test Coverage: covers more than what could be donemanually.

Ensures Consistency, Accuracy and Efficiency: The tests run are consistent,accurate and efficient.

Reliability and Transparency: The tests can perform the exact same stepsevery time without concern about human error.

Repeatability and Reusability: Once automate test cases i.e. convert the

test cases into test scripts, can be run any number of times and can bereused at a later point of time when needed.

Helps in Reduce coding for Large Test Cases and ease of testing of time-Consuming & Complex Test Cases

WHAT IS TEST AUTOMATION FRAMEWORK

A framework is an integrated system that sets the rules of Automation of a

specific product. Automation system integrates the function libraries, test datasources, object details and various reusable modules. The framework provides

the basis of test automation and simplifies the automation effort.

Provides an Outline of overall Test Structure

Ensures Consistency of Testing

Minimizes the Amount of Code for Development - thereby Less maintenance

Maximizes Reusability

Enables Test Automation using Data - Datapool


10/24

TYPES OF AUTOMATION FRAMEWORKS

Automation Framework are of four Types :

Data Driven Automation Framework

Keyword Driven Automation Framework

Modular Automation Framework

Hybrid Automation Framework


11/24

DATA DRIVEN AUTOMATION FRAMEWORK

Data-driven framework is where test input and output values are read from data

files (ODBC sources, cvs files, Excel files) and are loaded into variables in capturedor manually coded scripts

Repeated use of Test Scripts with Different Inputs and Response Data coming

out of Predefined Dataset

Easy to implement in IBM - RFT with the help of Data pools

Helps in Reducing Coding for Large Test Cases

Ease of Testing of Time-Consuming & Complex Test Cases


12/24

Continue..

Scripts may be developed while application development is still inprogress

Utilizing a modular design, and using files or records to both input and

verify data, reduces redundancy and duplication of effort in creating

automated test scripts

If functionality changes, only the specific "Business Function" script

needs to be updated

Data input/output and expected results are stored as easilymaintainable text records.

Functions return "TRUE" or "FALSE" values to the calling script, rather

than aborting, allowing for more effective error handling, and increasing

the robustness of the test scripts. This, along with a well-designed"recovery" routine, enables "unattended" execution of test scripts.

MERITS OF DATA-DRIVEN TESTING


13/24

DEMERITS OF DATA-DRIVEN TESTING

Requires proficiency in the Scripting language used by the tool (technical

personnel)

Multiple data-files are required for each Test Case. There may be any

number of data-inputs and verifications required, depending on how many

different screens are accessed. This usually requires data-files to be kept in

separate directories by Test Case

Tester must not only maintain the Detail Test Plan with specific data, but

must also re-enter this data in the various required data-files

If a simple "text editor" such as Notepad is used to create and maintain the

data-files, careful attention must be paid to the format required by the

scripts/functions that process the files, or script-processing errors will

occur due to data-file format and/or content being incorrect


14/24

KEYWORD DRIVEN AUTOMATION FRAMEWORK

Keyword-driven testing is a technique that separates much of the programming

work from the actual test steps so that the test steps can be developed earlierand can often be maintained with only minor updates, even when the

application or testing needs change significantly.

As the Name suggests, it enables Keyword Driven Testing or Table DrivenTesting

Data & Keyword Tables being Independent of the Automation Tool

The Keyword Driven framework consists of the basic components given below

1. Control File

2. Test Case File3. Startup Script4. Driver Script5. Utility Script


15/24

1. Control File

a. Consists details of all the Test scenarios to be automated

b. User will be able to select a specific scenario to execute based on turningon or off a flag in the Control File

c. Control File is in the form of an excel worksheet and contains columns forScenario ID, Execute (Y/N), Object Repository Path, Test Case File Path

2. Test Case File

a. Contains the detailed steps to be carried out for the execution of a testcase

b. It is also in the form of an excel sheet and contains columns for Keyword,Object Name, Parameter

3. Startup Script

a. The Startup script is utilized for the initialization and reads the control files

b. It then calls the driver script to execute all the scenarios marked forexecution in the control file

COMPONENTS KEYWORD DRIVEN AUTOMATION FRAMEWORK


16/24

4. Driver Script

a. It Reads the Test Case files. Checks the keywords and calls theappropriate utility script functions based on specific keyword

b. Error Handling is taken care of in the driver script.

5. Utility Scriptsa. Perform generic tasks that can be used across applications. It should

not be application dependent

Contd


17/24

The main advantage of this framework is the low cost for

maintenance. If there is change to any test case then only the TestCase File needs to be updated and the Driver Script and Startup

script will remain the same.

No need to update the scripts in case of changes to the application

ADVANTAGES


18/24

DISADVANTAGES

Development of "customized" (Application- Specific) Functions and Utilities

requires proficiency in the tools Scripting language.

If application requires more than a few "customized" Utilities, this willrequire the tester to learn a number of "Key Words" and special formats.This can be time-consuming, and may have an initial impact on Test Plan

Development. Once the testers get used to this, however, the time requiredto produce a test case is greatly improved.


19/24

MODULAR AUTOMATION FRAMEWORK

Dividing the large files into smaller scripts. Two types of Frameworks

Test Script Modularity Framework:

Enables creation of Small, Independent Scripts representing Modules &

Functions of the Application under Test (AUT)

Test Library Architecture Framework:

Enables creation of Library Files representing Modules & Functions of the

Application under Test (AUT)


20/24

HYBRID AUTOMATION FRAMEWORK

It is the Most Popularly Implemented Framework

It is a Combination of the above three types of Frameworks described

It has an Ability of evolving Itself Over a Passage of Time and Over Many

Projects


21/24

This hybrid test automation framework is what most frameworks evolve and multiple

projects.

The most successful automation frameworks generally accommodate both Keyword-

Driven testing as well as Data-Driven scripts.

The framework utilities can make the data driven scripts more compact and less

failure.

The utilities can also facilitate the gradual and manageable conversion of existing

scripts to keyword driven equivalents when and where that appears desirable.

The framework can use scripts to perform some tasks that might be too difficult tore-implement in a pure keyword driven approach, or where the keyword driven

capabilities are not yet in place.

HYBRID AUTOMATION FRAMEWORK


22/24

BENEFITS OF AUTOMATION FRAMEWORK APPROACH

Significant Reduction in Testing Cycle Time

Comprehensive Coverage against Requirements

Use of a "Common Standard" across all the Project Teams

Generation of Reusable Test Scripts ( Utility Functions)

Systematic Maintenance of Automation Scripts

Data Pooling
