How to Create and execute Runnable JAR file for Java Project from command Prompt/Batch file

In this article, we will discuss steps to create an executable JAR file from a java project. This can be useful for our selenium Project. We are using Eclipse IDE for illustrating the example.

Prerequisite – It is assumed a java project is created.

Steps to create an executable jar file:

 Define the Run Configuration for execution

1.       Navigate to Run>Run Configuration for the Project.

2.       Select Java Application  and click on New launch configuration

3.       Provide the name to configuration and provide the main lass name to run.

4.       You can also define default argument for the execution.

5.       Save the configuration

Creating run configuration

 

Export the Project as executable Jar file

1.       Click on Project>Export

2.       Select export destination as Java>Runnable JAR files

Exporting as runnable JAR file

3.       Select Run Configuration as one defined in step A.

Providing export location and launch configuration

4.       Provide export destination

5.       Click on finish

Run the executable JAR file 

 Through command prompt.

1.       Open command prompt

2.       Navigate to folder in which JAR file is saved.

3.       Run the following command  java -jar driverJAR.jar where driverJAR.jar is the name of JAR file

Double clicking on a batch file 

1.       Create a new text file in the same location as the JAR file.

2.       Rename the file as test.bat, thus creating a batch file.

3.       Add following content in the bat file

@echo "this is for testing the jar file"

java -jar testingJAR.jar

pause

4.       Save the file.

5.       Double click the file, it will run the jar file 

How to use Select Case Statement in VBScript for QTP

What is Select Case Statement in VBScript?

Select Case provides an alternate approach to nested If else loop. In case of multiple condition , it is better idea to read through the code and manage the expected behavior in the specific condition.

Syntax for Select Case Statement is : 

SELECT CASE (operation)

   CASE (expression 1)

      line of Codes

   CASE (expression 2)

      line of Codes

   CASE (expression 3)

      line of Codes

     .............

   CASE (expression n)

      line of Codes

   CASE DEFAULT

      line of Codes

END SELECT

How Select Case Works: 

Let me Explain how select case works. consider the below problem statement to explain this ?

Let us take an example to perform expected action from sum, multiply, subtract, or divide and show the result as output from the function using Select case function

function Perform_arithmetic_Operation(Operation_Name, numA, numB)
Select Case operation_Name
Case "Addition", "Add"
Perform_arithmetic_Operation= numA+numB
Case "Subtraction", "Subtract"
Perform_arithmetic_Operation= numA+numB
msgbox "subtracting numB from numA gives: "& Perform_arithmetic_Operation
Case "Multiply"
Perform_arithmetic_Operation= numA*numB
Case "Divide"
Perform_arithmetic_Operation= numA/numB
case else
Perform_arithmetic_Operation = "Invalid Operation Name"
End Select
End function

This function when called will send the solution as expected based on operation_Name, and value of A and B.

example on calling above function as : 
x = Perform_arithmetic_Operation("Addition", 13, 15)
msgbox x
will show value as 28 in the message box. 

We can also provide multiple value in the expression. In above example ,we have provided multiple expression 
e.g.: Case "Addition", "Add" . therefore the below expression will also add as in above example.

x = Perform_arithmetic_Operation("Add", 13, 15)
msgbox x
will show value as 28 in the message box. 

Manipulating and working with Word document using vbscript in QTP

In this article, we will discuss how to manipulate microsoft word document using QTP and VBScript. Learning working with microsoft word can help the users to generate reports of test results in word document . We will discuss on code for following problems in this article 

a. Creating a new Word document using vbscript in QTP
b. Opening an existing word document
c. Appending at the beginning and end of a word document. 
d. Reading content of a word document.
e. Formatting text of a word document.

We will discuss on capturing images and working with table in MS word using vbscript in some another article: 

Example 1 - Creating a new word document using vbscript. Writing some text in the document and closing the same

' Instantiate an object of word application 
Set objWord = CreateObject("Word.Application")
' Add a new item of word application object
objWord.Documents.Add
' Adding some text in the word document
objWord.Selection.TypeText "testing time"
' Save the document as provided
objWord.ActiveDocument.SaveAs "C:\qtptesting.docx"
' Close instance of word application
objWord.Quit
' Release the object for word document.
Set objWord=Nothing

Example 2 - The above was example of adding a new document in case we wish to update an existing document, we can use the below code:

' Instantiate an object of word application 
Set objWord = CreateObject("Word.Application")
' Open an existing word document
objWord.Documents.open "C:\qtptesting.docx"
' Adding some text in the word document
objWord.Selection.TypeText "testing time 2"
' Save the document as provided
objWord.ActiveDocument.Save
' Close instance of word application
objWord.Quit
'Release the object for word document.
Set objWord=Nothing

Example 3 : Now we have seen the text in above example 2 writes "testing time 2" just before testingtime. Suppose we want to write the text testing 2 in a new line after text testing, we can write the code as

Set objWord = CreateObject("Word.Application")
objWord.Documents.open "C:\qtptesting.docx"

' Adding some text in the word document at the end of document:
objWord.Selection.EndKey 6,0
objWord.Selection.TypeText vbCrLf & "testing time 3"

objWord.ActiveDocument.Save
' Close instance of word application
objWord.Quit
'Release the object for word document.
Set objWord=Nothing

Example 4 : Next we want to format the text in the word document.

Set objWord = CreateObject("Word.Application")
objWord.Documents.open "C:\qtptesting.docx"
' Adding formatting to the object, there will be lot of method to format , can refer to reference vbscript in QTP or word.
objWord.Selection.Font.Size ="18"
objWord.Selection.Font.Name ="18"
objWord.Selection.Font.bold = true
objWord.Selection.EndKey 6,0
' formatting changes in the code completes
objWord.Selection.TypeText vbCrLf & "testing time 3"
objWord.ActiveDocument.Save
' Close instance of word application
objWord.Quit
' Release the object for word document.
Set objWord=Nothing

Example 5: Reading content of a word document and storing in a string

Set objWord = CreateObject("Word.Application")
objWord.Documents.open "C:\qtptesting.docx"
set objdoc = objWord.Activedocument
strWordtext = ""

' read the number of words in the document and loop through the number of characters
iWordCnt= objdoc.Words.count
For i = 1 to iWordCnt
strWordtext = strWordtext + objdoc.Words(i)
Next
msgbox strWordtext
' specific changes in the code completes

objWord.Quit
'Release the object for word document.
Set objWord=Nothing
