Client Server And Web Applications, Essential Tools For your personal Desktop testing

Almost every tester works in one of the categories like desktop application, client server application or web application testing. Each app is different and has it’s own advantages and disadvantages.
WWW was developed on top of the existent client server architecture and it replaced the FTP and email as a mechanism of sharing files and data.
A program that can provide service to client programs is called a server. Client and server are connected with the help of message passing over the network using the protocol to encode the client's requests and the response of server. There might be a few distributed servers.
Web application is entirely run on a web browser. It is independent because only a web browser is required. As they are run inside the browser it means that the application which is run in Chrome will work either on Windows or OS X. They have finite access to system resources (e.g. memory, CPU, file system).
What is the difference between client server and web application?
For client server application testing must be 2 various components in order to test them. An application is loaded on server machine meanwhile the application exe on each client machine.
You should broadly test in such categories as GUI on both sides, Load, functionality, backend, client-server interaction while client server testing. You are informed about number of servers and locations and clients in the test scenario.
Some people prefer desktop apps, but others prefer web applications. So lots of companies (like Apple iWork, Microsoft Office or Intuit TurboTax) offer both desktop and web versions of the most popular programs.
Here are some more examples of incredibly useful desktop apps for Windows 10.
How is a web app different from a desktop application?
Now, let us consider what desktop testing is.
Desktop app testing means concentrating on a particular environment (personal computers, machines and systems). The app is tested in such categories as GUI, functionality, backend i.e. DB and Load. This type of testing requires knowledge of operating system and database as one focuses on definite environment.It means testing the application entirely in features like graphical user interface, functionality, backend, database and load. The user also needs to ascertain the ways to check memory leaks and unhandled exceptions.
Testing checklist for desktop applications may include the following:
- Graphical User Interface Testing
- Functional Testing
- Check for broken links
- Warning messages
- Resolution change effect on the application
- Theme change
- Installation Testing (Upgrade/Downgrade)
- Testing with multiple user accounts
- Sleep mode
- Compatibility Testing
- Testing the application on different operating systems
- Performance Testing
- Long period of continuous use
- Memory * Generate “Power Efficiency Diagnostics Report” by running the command powercfg /energy
Following tools may be useful for desktop testing.
AutoIt v3 is a freeware BASIC-like scripting language that is designed for automating the Windows GUI and general scripting. It uses a combination of simulated keystrokes, mouse movement and window/control manipulation in order to automate tasks in a way that is not possible or reliable with other languages (e.g. VBScript and SendKeys). It can interact with all conventional windows controls and support COM. But it is stand-alone with no external.dll files,.NET or VB.You can download it here https://www.autoitscript.com/site/autoit/downloads/
It is open-source custom scripting language for Microsoft Windows. The AutoHotkey installation includes its own extensive help file with always updated web-based version. AutoHotkey scripts are used to launch programs, open documents, send keystrokes and mouse clicks and movements. They can assign, retrieve, and manipulate variables, run loops and manipulate windows, files, and folders as well. One is able to remap or disable the keyboard keys.
An example of using this tool is hereIt may be download here https://autohotkey.com/download/
RanorexIt is a GUI test automation framework for testing desktop, web-based and mobile applications. Ranorex hasn't its own scripting language. It uses standard programming language like C# and VB.NET as a base. This tool supports such types of testing as acceptance test, black box test and unit test. You can test next desktop client applications: .NET, WinForms, Win32, Java, Qt, Delphi,VB6, PowerBuilder, WPF, Microsoft Dynamics CRM etс.

Bear in mind that even if the difference exists in these three environments, the basic quality assurance and testing principles remains the same and applies to all.
