Deciding on the right testing tool for a desktop app, might be a difficult task. These are the-Pros and Cons of 8 different open source test automation tools for desktop applications, written in WinForms/ WPF: AutoIT. AutoIT is a Stand Alone (doesn’t require any configuration) and small footprint tool, that simulates mouse and keyboard clicks.
Using UI Automation for Automated Testing. 6 minutes to read In this article This overview describes how Microsoft UI Automation can be useful as a framework for programmatic access in automated testing scenarios. UI Automation provides a unified object model that enables all UI frameworks to expose complex and rich functionality in an accessible and easily automated manner. UI Automation was developed as a successor to Microsoft Active Accessibility, a framework designed to provide a solution for making controls and applications accessible.
Microsoft Active Accessibility was not designed with test automation in mind, although it evolved into that role because of the similar requirements of accessibility and automation. UI Automation is specifically designed to provide robust functionality for automated testing, in addition to providing more refined solutions for accessibility. For example, Microsoft Active Accessibility relies on a single interface to expose information about the UI and to collect the information needed by assistive technology products; UI Automation separates the two models. Both a provider and a client are required to implement UI Automation for it to be useful as an automated test tool. UI Automation providers are applications, such as Microsoft Word, Microsoft Excel, and other third-party applications or controls based on the Windows operating system. UI Automation clients include automated test scripts and assistive technology applications.
This topic contains the following sections. UI Automation in Providers To automate an element of the user interface, the developer must look at what actions an end user can perform on the UI object by using standard keyboard and mouse interaction.
After these key actions have been identified, the UI Automation control patterns that mirror the functionality and behavior of the UI element should be implemented on the control. For example, user interaction with a combo box control typically involves expanding and collapsing the combo box to display or hide a list of items, selecting an item from the list, or adding a new value through keyboard input. With other accessibility models, developers must gather information directly from individual buttons, menus, or other controls.
Every control type comes in dozens of minor variations. In other words, even though 10 variations of a pushbutton work the same way and perform the same function, they must all be treated as unique controls. There is no way to know that these controls are functionally equivalent. UI Automation control patterns were developed to represent these common control behaviors. For more information, see. Without the unified model of control patterns provided by UI Automation, test tools and developers must have framework-specific information to expose properties and control behaviors in that framework.
Because several different UI frameworks can be present at the same time in Windows operating systems, including Microsoft Win32, Windows Forms, and Windows Presentation Foundation (WPF), it can be a daunting task to test multiple applications with controls that seem similar. For example, the following table lists the framework-specific property names required to retrieve the name or text associated with a button control and shows the equivalent UI Automation property. Control type UI framework Framework-specific property UI Automation property Button WPF Content Name property Button Win32 Caption Name property Image HTML alt Name property UI Automation providers are responsible for mapping the framework-specific properties of their controls to the equivalent UI Automation properties. For information on implementing UI Automation in a provider, see. For information on implementing control patterns, see. UI Automation in Clients The goal of automated test tools and scenarios is the consistent and repeatable manipulation of the UI.
For example, this can involve unit testing specific controls, and recording and running test scripts that iterate through a series of generic actions on a group of controls. A complication in automated applications is the difficulty of synchronizing a test with a dynamic target, for example, a list box control, such as Windows Task Manager, that displays a list of currently running applications.
Because the items in the list box are dynamically updated outside the control of the test application, an attempt to repeat selecting a specific item in the list box with any consistency is impossible. Similar issues can arise when attempting to repeat simple focus changes in a UI that is outside the control of the test application. Programmatic Access Programmatic access provides the ability to imitate, through code, any interaction and experience exposed by traditional mouse and keyboard input.
UI Automation enables programmatic access through five components:. The UI Automation tree facilitates navigation through the structure of the UI. The tree is built from the collection of HWNDs.
For more information, see. Automation elements are individual components in the UI. These can often be more granular than an HWND. Automation properties provide specific information about UI elements.
For more information, see. Control patterns define a particular aspect of a control's functionality; they can consist of property, method, event, and structure information. For more information, see. Automation events provide event notifications and information. For more information, see. Key Properties for Test Automation The ability to uniquely identify and subsequently locate any control in the UI provides the basis for automated test applications to operate on that UI.
UI Automation properties used by clients and providers to identify and locate controls are described in the following table. Property Description AutomationId Uniquely distinguishes an automation element from its siblings. Support for the AutomationId property is not required.
When it is available, the AutomationId property of an element is the same in any instance of the application, regardless of the local language. Although the AutomationId property is unique among sibling elements, it may not be unique across the entire desktop. For example, multiple instances of an application, or multiple folder views in Microsoft Windows Explorer, may contain elements with the same AutomationIdProperty, such as 'SystemMenuBar'. Clients should make no assumptions regarding the AutomationIds exposed by other applications. AutomationId is not guaranteed to be stable across different releases or builds of an application. ControlType Identifies the type of control represented by an automation element. Significant information can be inferred from knowledge of the control type.
For more information, see. Name A text string that identifies or explains the purpose of an automation element. It should be used with caution because it can be localized.
The Name property is not a unique identifier among siblings. For test automation, clients should use the AutomationId property or RuntimeId property instead. RuntimeId An array of integers that represent an identifier for an automation element. The identifier is unique on the desktop, but is guaranteed to be unique only to the UI of the desktop on which it was generated.
Identifiers can be reused over time. Use to determine if the element that currently has a particular runtime ID is the same element that previously had that ID. Also, the format of the RuntimeId property may change. It should be treated as an opaque value and used only for comparison; for example, to determine whether an automation element is in the cache.

I want to write the automation suite for windows services. Some of these services updates the data in database. So my test cases would be to check the current state of the DB, run the windows service and verify the changes in the DB(SQL Server). What tools would be best option for performing this kind of testing. It will be more helpful if this tool can integrate with testNG or jUnit, and have a database connectivity option with SQL server as well.
Visual studio is obviously an answer, but just want to know if there are some tools available for this particular case. According to my understanding you can use selenium with testNG or Nunit or MStest. As you mention your scenario will be: 1).check the current state of the DB To do that in selenium write a test method to open a SQL connection to the desired server and check the status or check the values at the table and save it as a string type variable. 2).Run the windows service: This is simple to invoke a windows service thru the c# code.
3).Verify the changes in the DB: To perform this again write a method to open a SQL connection to the desired server and check the new status or check the new values at the table and save it in another string variable. At last compare the 1st string value and 2nd string value using an assert commend. Visual Studio itself is an IDE, an Integrated Development Environment - not a tool for interacting with databases. However, there are.NET CLR (Common Language Runtime) libraries for programmatic DB access. I recommend, however, that you start with the asking the developers to create product hooks for you to use to interact with the database.
Windows Application Automation Testing
This is likely to be safer than interacting with it directly with your tests. I'm pretty decent with programmatic DB access and still prefer to do it, when testing, through product hooks that are disabled in production. Product hooks definitely will get wrapped in tests and verified for consistent, well-understood behavior (unless the team is very lax). Test libraries, on the other hand, tend to get less care and are more likely to have bugs and unexpected side effects. Also, it simplifies how to manage authentication, as the product already authenticates for DB access. Barring that, see how the developers and the product code interface with the databases. They may already have some great tools that simplify DB access compared to the libraries you would normally use, or they may have tools that enforce certain rules around how you access the DB that you need to use.

If that fails, you probably want to look at the database access classes in the CLR: page is a good place to start. The MSDN documentation on, in particular, will contain the bulk of what you need to know. If you go this route and are not familiar with database access code, I strongly recommend getting both test design reviews and code reviews from the product developers. There are often security implications around how the tests handle database authentication, and database interactions can have messy and long-lasting impacts on test environments.
