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 • Web Services • Telnet • FTP • XML
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
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: • COM+ • Distributed COM (DCOM) • ActiveX Controls.
COM methods and properties • COM properties and methods • Properties don’t 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)
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

Using WinInet API for FTP • Windows WinINet.DLL enables applications to interact with the following protocols: • FTP • HTTP • Gopher
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
ActiveX components (COM) for FTP • The are numerous ActiveX (COM) components for FTP free and not free: • by Chilkat Software www.chilkatsoft.com • by Easewe Software www.easewe.com • by X360 Software www.x360soft.com • by Dart Communications www.dart.com • etc.

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.

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/w3Sockets/Reference/Refstart.htm
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: • http://www.tek-tips.com/viewthread.cfm?qid=938038&page=3 • http://www.mediamonkey.com/forum/viewtopic.php?t=21124
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
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.
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
WinHttp.WinHttpRequest.5.1 Methods and Properties Methods of WinHttp • Abort: Aborts a WinHTTP Send method. • GetAllResponseHeaders: Retrieves all HTTP response headers. • GetResponseHeader: Retrieves the HTTP response headers. • Open: Opens an HTTP connection to an HTTP resource. • Send: Sends an HTTP request to an HTTP server. • SetAutoLogonPolicy: Sets the current Automatic Logon Policy. • SetClientCertificate: Selects a client certificate to send to a Secure Hypertext Transfer Protocol (HTTPS) server. • SetCredentials: Sets credentials to be used with an HTTP server—either an origin or a proxy server. • SetProxy: Sets proxy server information. • SetRequestHeader: Adds, changes, or deletes an HTTP request header. • SetTimeouts: Specifies, in milliseconds, the individual time-out components of a send/receive operation. • WaitForResponse: Specifies the wait time, in seconds, for an asynchronous Send method to complete, with optional time-out value. Properties of WinHttp • Option: Sets or retrieves a WinHTTP option value. • ResponseBody: Retrieves the response entity body as an array of unsigned bytes. • ResponseStream: Retrieves the response entity body as an IStream. • ResponseText: Retrieves the response entity body as a string. • Status: Retrieves the HTTP status code from the last response. • StatusText: Retrieves HTTP status text.
