Java Objects

A Java object is a set of data combined with methods for manipulating data. An object is made from a class; a class is the blueprint for the object. Each object made from a class will have its own values for the instance variables of

that class. The three steps to creating a Java object are:

Object Declaration Object Instantiation Object Initialization

Object Declaration - Declaring an object associates a variable name with an object. Object Instantiation - Instantiating an object allocated space in memory for the

object. This is accomplished with the new operator Object Initialization - Initializing an object fills the objects varibles with an initial set

of values. This is accomplished using a constructor.

4

Create Objects This statement creates a new Date object (Date is a class in the java.util package). This single statement actually performs three actions: declaration, instantiation, and initialization.

Date EmpJoin = new Date (1996, 8, 30 );

Object Declaration

(type name :Date EMPJoin)

Object Instantiation

(new)

Object Initializationtype(value) : Date(1996,8,30)

Java Class A Java class is a group of Java methods and variables. The implementation of a class is comprised of two components: the class

declaration and the class body. The class declaration component declares the name of the class along with other

attributes such as the class's superclass, and whether the class is public, final, or abstract.

The class body contains declarations for all instance variables and class variables (known collectively as member variables) for the class

class Sample { int variable a; int variable b; String name; }

class declaration class body

Java Methods A java method is a series of statements that perform some repeated task. Every Java program must have one main() method. A method implementation consists of two parts: the method declaration and the

method body. A method declaration has a name and a return type indicating the data type of the

value returned by the method. The method body is where all of the action of a method takes place.

public static void main (String[] args)

{ System.out.println{"Hello World!"); }

Steps for Java scripting

Identify the scenarios to be created as method and group of method to be created as task

Create task and testcase folder Add Empty Script Declare Methods Insert Test Object Perform Action Under Test Insert Verification Points Call methods in test case script Playback the Script

8

Create Task and Test Case folder

Select the name of the project Right click new folder Enter names (as task and

testcase) and select finish.

9

Add Empty Script• Right Click on test folder Add Empty Script.• Enter name of script(Login_demo) and click on Finish.

10

Declare Methods

By default one main method is already declared in script . Syntax to declare method is ‘returnType methodName() { . . . } ‘ Below is the code to declare the method names ‘loginDetails’

11

Insert Test Object In this step insert the test object which are required for the method

Step 1: Right Click on test objects and select insert test object.

Step 3: Click on Finish

Step 2: Test Object will now appear in test object map

12

Perform Action Under Test Tester insert the action to be undertaken on the test object inserted in

pervious step.

AUT Command

13

Insert Verification Points

In this step insert the verification which are expected to be verified.

mainwindow().performTest( mainPanelVP() );

Step 1 : Right click on VP and select Insert VP Step 2: Select Object to be verified.

Step 3 : Select type of VP

Step 4: command for VP in Script

14

Script view After adding test object , AUT and verification points script will

appear like this

15

Call methods in test case script Import the script from task folder

whose method is to be used here.

Declare the method

Use the method

16

Call methods in test case script

After calling methods in test case script it appears like this :

Best Practices for RFT Script Writing Handle uncaught exception by surrounding with try/catch or adding catch block to

a surrounding try block.

Use TestObject.find to locate a TestObject in the application under test (AUT) dynamically

Use deleteCookies method in your scripts

Check the .readystate of the browser object

Use waitForExistence method to compensate for browser startup speed

Selection of type of VP to be used

18

Try catch Handle uncaught exception by surrounding with try/catch or adding catch block to a

surrounding try block .

19

TestObject.find

The TestObject.find method is a Java™ method that the IBM Rational Functional Tester tool uses to locate a TestObject in the application under test (AUT) dynamically, at runtime.

The advantage is that you do not have to change the recognition properties stored in an Object Map, so you avoid the more tedious and time-consuming way of using the Object Map UI to make the changes or rerecording the object to update it.

Methods which can be used with find are : atChild searches for any direct child of the TestObject.

atDescendant looks for any child of the TestObject.

atList lets you specify a list of atChild, atDescendant, and atProperty objects, so you can narrow the search.

Delete cookies

By deleting cookies in scripts , script execution become faster. There are two types of method available in RFT for deleting cookies Method 1

delete Cookies()            Description :- Deletes all of the browser's cookies. 

Method 2 delete Cookies (java.lang.String cookie, boolean recursive)            Description :- Deletes browser cookies specified by the path in cookie

21

readyState()

.readyState () is a property of HTML browser which indicates the current status of browser.i.e it indicates whether the browser is ready for use or not .

It indicates the integer value and each integer represents the state in which browser is .For complete state integer value is 4.

Sometimes script playback for testing HTML application fails if the ready state of the browser object is not 4 .

To avoid above problem tester can capture and ensure that value should be 4 before moving further.

String a = browser_html ().getProperty(".readyState").toString();

Sample Code

22

waitForExistance()

Each browser start up time is different .for e.g. wait time in IE is less as compared to Netscape.

Above property causes problem while doing cross platform execution. To avoid the above problem tester can use ‘waitForExistence()’ method of RFT Below is the sample code.

startApp(“test”);browser_html. waitForExistence();

home().click();

23

Selection of type of VP to be used

Manual verification points are useful when tester create the data for the verification point yourself, and than want to compare the data.

The data could be the result of a calculation or could come from an external source, such as a spreadsheet, datapool, database, or custom calculation.

vpManual ("ManualVP_01", "Check something manually.", "Check something manually.").performTest();

When to use Manual VP

When to use Dynamic VP

Sometimes, tester need to perform verification points on test objects that aren't in test object map. For that purpose dynamic VP is used Dynamic verification points raise the appropriate user interface the next time that the script is played back. vpDynamic ("DynamicVP_01", TestObjectHere()).performTest();
