You can use the Using Sort() methods and then Reverse() method. An array only has items of the same type and its size if fixed. An interface is a class that does not have any implementation. Only the declarations of events, properties, and attributes are included.
- On average, a C# developers can expect to make approximately $84,243 annually.
- I explained that automation testing is like having a robot perform certain repetitive tasks that a human would otherwise do.
- Employers ask this question to see if you have a passion for your work and how much you’re willing to learn.
- Memory, security, and other activities related to execution will be handled by the application’s runtime.
- These are frequently asked interview questions in C# interviews and designed for freshers.
- For example, checking the background color of a window or dialog box.

How do you create a LINQ extension method?
Write code to calculate the circumference of the circle, without modifying the Circle class itself. Given an array of ints, write a C# method to total all the values that are even numbers. Selenium supports scripting in languages like Java, C#, Python, Ruby, PHP, Perl, and JavaScript. Achieving 100% automation is difficult as there are some scenarios where a registration page has a captcha or some test cases we don’t execute often.
By doing this we can verify that the code is working in an expected manner or not. Anything outside the browser is also restricted to access in the test scenario execution. If Selenium web driver is used, then no need to use the dependency of the selenium server. Overall, the Verify statement does not halt the program execution whereas the Assert statement does halt the execution. We can specify the port number too i.e., TCP/IP port to connect the Selenium tests to the Grid hub. We need to make sure that there is no other application with the same port number up in any other location within the same machine.
Is C# code managed or unmanaged code?
When we initialize a multithreaded application, thread pooling is used to create a collection of threads that can be reused when new tasks require a thread. This removes the need to create new threads for each new task. These methods and properties are only declared and have no definition or fields as these are defined within the class that the abstract class interface inherits. It is best practice to name an interface class with ‘I’ to identify it as an interface visually. When writing to a file, we use the output stream, and when reading from a file, we use the input stream. We use the System.IO namespace to access static methods for file handling.
Here the UI tests take the ground by regressing multiple units in a single test. These tests tend to be fragile and could be very slow in execution. Hence, each layer has a significant role in the overall testing strategy.
When writing API document, what must be considered?
This question is designed to test your problem-solving skills and your ability to handle real-world challenges in test automation. AJAX calls and dynamic elements can make automating tests more complex, so I want to see if you can come up with a solution to handle these situations. Additionally, providing examples of how you’ve successfully handled AJAX calls or dynamic elements in past projects can further demonstrate your expertise. I like to think of the Page Object Model as a design pattern that helps create more maintainable and organized test automation scripts.
Because of this composition, we can refer to a jagged array as an ‘array of arrays’. Each non-generic collection can be used to store different types as they are not strongly typed. Note that this is one of those C# important questions you need to understand properly.
Top 50 C# Interview Questions and Answers (
Use your answer to highlight some of your most important qualities, such as attention to detail, communication skills and problem-solving ability. Tell me about a project you worked on recently where you implemented automation into the development process. Describe your experience with creating test scenarios and manual testing. They allow multiple developers to work on the same class easily. Automating routine tasks and executing test cases multiple times, in multiple devices, at a large scale becomes easily doable with the help of QA automation.
The first thing I did was gather data on the runtimes and pass/fail rates of all the test cases. I then used visualization tools to plot the data and identify trends and patterns. This helped me easily spot where bottlenecks or issues were occurring. Furthermore, I introduced the use of feature branches and pull requests in our version control system. This allowed developers to work on their tasks independently, while I could review and approve their changes before merging them into the main branch. As a result, we were able to maintain the stability of the staging environment and ensure our automated tests ran seamlessly alongside code updates.
What is the reason behind the invention of C#?
In Hashtable, keys are used to access the elements present in the collection. For very large Hashtable objects, you can increase the maximum capacity to 2 billion elements on a 64-bit system. A code that is written to aimed to get https://wizardsdev.com/en/vacancy/qa-automation-engineer-c/ the services of the managed runtime environment execution like CLR in .NET Framework is known as Managed Code. It is always implemented by the managed runtime environment instead of directly executed by the operating system.
With the help of a selenium web driver, one can easily automate browser testing. Selenium Remote Control is a server with which the user can create the Test cases in any desired programming language. The commands present in the test scripts are accepted by the server and sent to the browsers as the Selenium core Java script commands to maintain the browser behaviour accordingly. Still, we need your love and support to make this platform more helpful to our fellow testers.
