QTP: Not just for GUI anymore Prepared by: Igor Gershovich www. connectedtesting. com

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

Topics n n Web Services Telnet FTP XML

Advantages using APIs n Accessing non-GUI applications via API directly: q q Increases test execution speed Reduces synchronization problems related to GUI window like Telnet, DOS CMD, Pu. TTY, Exceed, etc. Allows execute scripts on locked boxes No need for QTP add-ins

Let’s 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: n COM+ n Distributed COM (DCOM) n Active. X Controls.

COM methods and properties n COM properties and methods Properties don’t take any arguments and can be read/write value = object. property (read) object. property = value (write) q Methods are read only if they returns 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) q

VBScript Create. Object function creates and returns a reference to an Automation object Create. Object(servername. typename [, location]) Example connecting to Quality Center (QC): Set tdc = Create. Object ("TDApi. Ole 80. TDConnection") tdc. Init. Connection. Ex s. Server. Name 'Connect tdc. Login s. User, s. Password tdc. Connect s. Domain, s. Project

File Transfer Protocol (FTP)

Using Win. Inet API for FTP n Windows Win. INet. DLL enables applications to interact with the following protocols: q q q FTP HTTP Gopher

FTP: File download steps 1. 2. 3. 4. Open an FTP session with Internet. Open function. The function returns a session handle. Connect to the host by calling the Internet. Connect function using session handle. It returns a connection handle. Call the Ftp. Get. File function to get the file. Close the handles created in Steps 1 and 2, using the Internet. Close. Handle function

Telnet to Unix/Linux using COM objects

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 Pu. TTY, 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 Load. Runner Win. Sock protocol for Telnet interface I start looking for Win. Sock (Active. X) 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 Get. Visible. Text method.

Active. X components (COM) for Telnet n The are numerous Active. X (COM) components for Telnet free and not free: q q by Dimac Development www. dimac. net Easy. Com 3. 1 www. sharewareconnection. com/easycom. htm by Dart Communications www. dart. com etc.

Dimac W 3 Socket API installation n n You need to download W 3 Socket Dll to your location and register it using Socket. Reg. exe included in a zip file. Note: Readme said that you need to download winsock 2 also - ignore it. The full W 3 Sockets reference is located: http: //www. dimac. net/Products/Free. Products/w 3 Sockets/Reference/Refstart. htm n

Example for Unix/Linux n The function on next slide: q q n connect to Unix/Linux box via Telnet navigates to Test. Directory executes “grep” command returns “grep” results You can also find more examples on Web: q q http: //www. tek-tips. com/viewthread. cfm? qid=938038&page=3 http: //www. mediamonkey. com/forum/viewtopic. php? t=21124

W 3 Sockets API limitation n This API has a problem with Send. Line method when sending over 80 characters.
