Q: What is Coded UI testing?
Ans:
Microsoft offers a testing framework called "coded UI testing" for automating user interface (UI) tests. It enables testers to develop automated tests by writing C# or Visual Basic code that communicates with the user interface of the application.
Q: What are the advantages of Coded UI testing?
Ans:
- For improved testing management and reporting, coded UI tests can be integrated with Visual Studio and TFS.
- It supports a variety of technologies, including SharePoint, web applications, and Windows applications.
- It improves test coverage while helping in lowering the amount of manual testing efforts.
- End-to-end testing, including UI interactions, data validation, and functional testing, can be automated using coded UI testing.
Q: What are the different types of UI actions that can be performed using Coded UI testing?
Ans:
Different UI operations are supported by coded UI testing, such as button clicks, textbox input, mouse clicks, keyboard input, choosing options from drop-down lists, and checking text or control properties.
Q: How to handle data-driven testing in Coded UI?
Ans:
Data-driven testing is possible with coded UI testing since it has the ability to bind test data from external databases, CSV files, and Excel spreadsheets. To do this, users can make advantage of the framework's data sources and data-driven testing features.

Q: How to create reusable code in Coded UI testing?
Ans:
By grouping your test code into methods and classes, you may build reusable code when using Coded UI testing. To encapsulate frequent activities, such as login, navigation, or data validation, developers can create helper methods or classes. This is beneficial in keeping the test codebase modular and manageable.
Q: How to handle dynamic controls in Coded UI testing?
Ans:
To handle dynamic controls use methods like searching for controls based on their
characteristics or identifying controls with regular expressions. This may be accomplished by
utilizing the UITestControl.SearchProperties and UITestControl.FilterProperties
methods.
Q: What is cross-browser testing, and can Coded UI testing be used for it?
Ans:
To ensure compatibility and consistent behaviour, online apps are tested across a variety of web browsers. Web and Windows apps on Internet Explorer are the main targets of coded UI testing. Cross-browser testing is not, however, explicitly supported.
Q: How to handle pop-up windows or dialogs in Coded UI testing?
Ans:
Use the MessageBox or ModalWindow classes offered by Coded UI testing
to manage pop-up windows or dialogue boxes. We can interact with modal windows using these
classes and carry out actions or validations.
Q: How to generate test reports in Coded UI testing?
Ans:
Test results from coded UI testing can be exported to HTML or XML format or integrated with tools like Microsoft Test Manager to produce test reports. To create test reports, user can configure the test settings and the desired result format.
Q: What are some best practices for writing maintainable Coded UI tests?
Ans:
- To increase code readability, use meaningful control and method names.
- Separate test data from test logic by using data-driven testing.
- To make debugging easier, implement appropriate exception handling and logging.
- Keep test files and resources in a clean folder structure.
- To reduce repetition, keep test code modular and reusable.
- To ensure the maintainability of test code, regularly examine and refactor it.
Q: Is it possible to integrate Coded UI testing with Continuous Integration (CI) systems?
Ans:
It is possible to combine Coded UI testing with CI tools like Jenkins, TeamCity, or Azure DevOps. Coded UI tests can be run as part of the CI process by configuring build pipelines or jobs, which can then produce reports or start notifications based on the test results.
Q: How to handle security testing in Coded UI testing?
Ans:
By interacting with authentication processes, verifying HTTPS connections, or checking access control rules, coded UI testing can be utilized to automate security testing scenarios. To mimic various user roles, permissions, and security-related circumstances, users can develop test code.
Q: How to handle synchronization issues in Coded UI testing?
Ans:
Synchronization solutions are offered by coded UI testing to address synchronization problems.
When executing actions or making assertions, users can use the WaitForControlExist,
WaitForControlEnabled, and WaitForControlReady methods to wait for
particular controls or circumstances to occur.
Q: How to handle exceptions or errors in Coded UI testing?
Ans:
Errors that occur while running tests can be handled through exception handling methods in coded
UI testing. Try-catch blocks can be used to handle or log errors properly and catch
exceptions.
Q: How to handle browser-specific testing in Coded UI?
Ans:
On Internet Explorer, coded UI testing is compatible with cross-browser testing. However, users might need to investigate alternative tools or frameworks like Selenium WebDriver for browser automation if need to test on other browsers like Chrome or Firefox.
