Test Automation

Performing the testing tasks using automationtools is known as test automation.

OR

It is a process of using the software to controlthe execution of tests and comparison of actualoutcomes with the predictable outcomes.

Note: Commonly S/W test automation isautomating the manual testing process currentlyin use.

Benefits of Automation

1. Fast:-

Run faster than human users.

Eg: To execute 2500 test cases it takes 3months. In tool it will take 3-4 days cost willbe less as the time is saved.

2. Reliable:-For the same operations performed each

time, results obtained can be trusted over atime, as there is no human interface.


3/61

3. Repeatable:-

Scripts written for an application or module can

be executed time and again for many times. Likefor regression and smoke testing we need toexecute test cases repeat ably in that case it isvery beneficial.

4.Reusable:-

Test script written for a module if needed inafter some time for another module same as

pervious one script can be copied and used asmany time as needed.


4/61

5. Scalable or Programmable:-

It is possible to modify the script written earlier.

Eg: we get a change in requirements after release ofbuild in such case need not to write whole scriptfrom beginning, we can use pervious script and can

just add or delete programmable features as per

need.6. Comprehensive:-

No of requirements covered by test script is very

large.Eg: In manual testing for each requirement

corresponding test case is desired. Thus the volume

of test cases is very large. But single test script

Test Automation process overview

1. Prepare automaton frame work

2. Evaluate the tool (Which tool we have to use)3. Create object repository

4. Generate obtain test data

5. Generating the test script as per the test suits.6. Review the script

7. Fix review comment

8. Enhance the test script9. Debug the script

10. Execute test script

11. Analyze the result


6/61

Evaluation Of Tool

Factors consider to select a particular tool for

automation.1. Compatibility Issue:-

The tool support the environment or not. Like

.NET environment not for Win Runner.

2. Cost Consideration/Licensing:-

What is cost of tool and how many license arerequired.

16/61

Implicit Declaration:-

If variables are not declare in thebeginning it is called implicitdeclaration.

Option Explicit:-Its a function used to write before

writing program, it tells each variable

should be declared separately. This is

called Explicit and in VB Its optionally.

Arrays

An array is a structured data type consistingof a group of elements that share a commonname and each element can be of same or

different data type.

Collection of similar data type.

Arrays can be declared in two ways.

1. Fixed Array

2. Dynamic Array

Fixed Array


45/61

Fixed ArrayThe array element is fixed, we have to give the

array size.

Eg:-

Dim std(03)

std(0) ="Arun"

std(1)="Venket"

std(2)="Ganesh"

std(3)="lo"best=std(3)

MsgBox best


46/61

Dynamic Array

The array element is not fixed we can put asmany as value we want.

Eg:-

Dim std, best

std=array("a","b","c","d","e","f")

Best=std(4)msgbox best


47/61

Re-Dimensioning Of Array

Once the size of an array isdeclared and further in future

while writing a program wants toalter the array size, For that we

use ReDim key word.


48/61

Preserve

When we re-dimension the array the earlierelements will erase.

If you want to save earlier data. Then we use akey word called preserve.

This is the use of preserve.

Example for both Redim and preserve:-


49/61

Example for both Redim and preserve:

ReDim std(3)

std(0)="a"

Std(1)="b"

std(2)="c"

std(3)="d"

For i = 0 to 3

Note:-Continued in next page.


50/61

msgbox std(i)

NextReDim preserve std(4)

std(4)="f"

For i = 0 to 4msgbox std(i)

Next

QTP testing Overview process


55/61

QTP testing Overview process

The QuickTest testing process consists of 7 mainphases:

1. Preparing To Record:-

Before recording a test, confirm that the applicationand QuickTest are set to match the needs of the test.

Make sure the application displays elements on whichthe recording should be done, such as a toolbar or a

special window pane, For example, and that theapplication options are set as expected for thepurposes of the test.


56/61

2. Recording A Session On The Application:-

As navigated through the application

or Web site, QuickTest graphically displays

each step performed in the form of acollapsible icon-based test tree. A step is any

user action that causes or makes a change in

the application, such as clicking a link orimage, or entering data in a form.


57/61

3. Enhancing The Test:-

Inserting checkpoints into the test lets to search for a

specific value of a page, object or text string, which

helps to identify whether or not the application or site is

functioning correctly?Broadening the scope of the test, by replacing fixed

values with parameters, lets to check how the

application performs the same operations with multiple

sets of data.

Adding logic and conditional statements enables to add

sophisticated checks to the test.


58/61

4. Debugging The Test:-

A test is debugged to check that it operatessmoothly and without interruption.

5. Running The Test:-

A test is executed to check the behaviorof the application or Web site. While running,QuickTest opens the application, or connects to the

Web site, and performs each step in the test.


59/61

6. Analyzing The Test Results:-Examine the test results to pinpoint

defects in the application.

7. Reporting Defects:-If TestDirector is installed, the defects

discovered can be reported to a database.TestDirector is Mercury Interactive softwaretest management tool.

What is Add-in?


60/61

Add in provides set of classes, methods andproperties to QTP, So that QTP can understand the

application and perform the operation.By default QTP comes with 3 Add-ins:

1. Web

2. ActiveX3. Visual Basics

QTP does not require any Add-in to work on Standard

windows applicationAdd-ins can only be loaded when starting QTP

Once the selected Add-ins are loaded, QTP window

will show up
