QTP: Not just for GUI anymore

1
QTP Not just for GUI anymore

• Prepared by Igor Gershovich
• www.connectedtesting.com

2

• The true beauty of QTP is that the only
  limitation is your imagination and ability to
  code in VBScript.
• Ian Fraser

3
Topics

• Web Services
• Telnet
• FTP
• XML

4
Advantages using APIs

• Accessing non-GUI applications via API directly
• Increases test execution speed
• Reduces synchronization problems related to GUI
  window like Telnet, DOS CMD, PuTTY, Exceed, etc.
• Allows execute scripts on locked boxes
• No need for QTP add-ins

5
Lets talk about Component Object Model (COM)
first

• COM is used by developers to create reusable
  software components, link components together to
  build applications, and take advantage of Windows
  services.
• The family of COM technologies includes
• COM
• Distributed COM (DCOM)
• ActiveX Controls.

6
COM methods and properties

• COM properties and methods
• Properties dont take any arguments and can be
  read/write
• value object.property (read)
• object.property value (write)
• Methods are read only if they returns value
• value object.method() (returns value)
• Set RS Conn.Execute(Select From Tbl")
  (returns object)
• Conn.Close (returns no value)
• tdc.Login username", psw" (method with
  parameters, returns no value)

7
VBScript CreateObject function

• CreateObject function creates and returns a
  reference to an Automation object
• CreateObject(servername.typename , location)
• Example connecting to Quality Center (QC)
• Set tdc CreateObject ("TDApiOle80.TDConnection")
  
• tdc.InitConnectionEx sServerName 'Connect
• tdc.Login sUser, sPassword
• tdc.Connect sDomain, sProject

File Transfer Protocol (FTP)
11
Using WinInet API for FTP

• Windows WinINet.DLL enables applications to
  interact with the following protocols
• FTP
• HTTP
• Gopher

12
WinInet FTP hierarchy
13
FTP File download steps

• Open an FTP session with InternetOpen function.
  The function returns a session handle.
• Connect to the host by calling the
  InternetConnect function using session handle. It
  returns a connection handle.
• Call the FtpGetFile function to get the file.
• Close the handles created in Steps 1 and 2, using
  the InternetCloseHandle function

Telnet to Unix/Linux using COM objects
20
A little bit of history

• A while back I had to automate a Client/Server
  application and execute quite a few UNIX commands
  on a backend.
• After trying several things, like PuTTY, TE
  Add-in, Exceed, etc.
• Exceed worked decent enough, but it was a
  complicated solution. I had to use "Capture to
  File" feature and then parse the file.
• After working with LoadRunner WinSock protocol
  for Telnet interface I start looking for WinSock
  (ActiveX) COM interface that can be used in QTP
• The goal was to connect to Unix/Linux box
  bypassing external GUI applications and execute
  scripts on locked boxes. Another reason was that
  QTP has problems with GetVisibleText method.

ActiveX components (COM) for Telnet

• The are numerous ActiveX (COM) components for
  Telnet free and not free

Dimac w3sockets DLL methods and properties

•       COM Object - socket.tcp
•     Buffer StringDoTelnetEmulation
  BooleanHost StringTelnetEmulation
  StringTimeOut IntegerClose() GetLine()
  StringGetText( len ) StringOpen()
  SendLine( Line ) SendText( text ) Wait()
  WaitFor( Substring ) BooleanWaitForDisconnect(
  )

23
Dimac W3Socket API installation

• You need to download W3Socket Dll to your
  location and register it using SocketReg.exe
  included in a zip file.
• Note Readme said that you need to download
  winsock2 also - ignore it.
• The full W3Sockets reference is located
•  http//www.dimac.net/Products/FreeProducts/w3Sock
  ets/Reference/Refstart.htm

24
Example for Unix/Linux

• The function on next slide
• connect to Unix/Linux box via Telnet
• navigates to TestDirectory
• executes grep command
• returns grep results
• You can also find more examples on Web

W3Sockets API limitation

• This API has a problem with SendLine method when
  sending over 80 characters.

HP/Mercury Solutions for WebServices

• The HP Service Test software is a SOA testing
  solution that simplifies and accelerates the
  automated functional testing of SOA services. HP
  Service Test Management module plugs into Quality
  Center
• QTP Web Services add-in

30
Windows APIs for Web Services

• HP Service Test and QTP Web Services Add-in are
  great solutions for comprehensive Web Services
  testing. However, the lightweight solution using
  Windows APIs works perfect in most cases.

31
WinHTTP DLL

• Microsoft Windows HTTP Services (WinHTTP)
  provides developers with a server-supported,
  high-level interface to the HTTP/1.1 Internet
  protocol.
• WinHTTP WinHttpRequest COM object uses Winhttp.dll

Msxml2.DOMDocument

• A DOM for XML is an object model that exposes the
  contents of an XML document
• We use the XML DOM by creating an instance of an
  XML parser
• CreateObject(Msxml2.DOMDocument ) is the
  method to create an instance of the Parser object
  
• Msxml2.DOMDocument COM object uses Msxml.dll
