8 Coded UI Interview Questions

Here are eight Coded UI interview questions, together with an example answer and explanation for each:

1. Can you explain what automation testing is?

Interviewers often like to ask questions regarding the definition of certain terms. The important thing to remember is to give more information than just a definition. This allows you to demonstrate your working knowledge. Moreover, if the interviewer asks you about automation testing, this means that you can probably expect it to be part of the job, so you want to indicate competency and familiarity with it in your answer.

Example answer: This is a useful technique for testing software. It involves an expected outcome and an actual outcome, which we can compare to derive insights and results. We use it to test products, scripts or applications using hypothetical inputs. The benefit of this is that you can repeat it without using up a lot of time, which often makes it preferable to testing manually. You can often perform the majority of the necessary testing for a software application using this technique.

2. What are the benefits of Coded UI?

This is a question that you are more likely to get toward the beginning of the interview. The interviewer wants to know if you understand the benefits of Coded UI, as this indicates an understanding of your tools in the context of your work tasks. This is also an opportunity to show your familiarity with it by giving some more detail about its functionality, especially in relation to the work of developers.

Example answer: There are quite a few benefits to Coded UI. One of the most important is that it allows a user to test how functional their code is. Additionally, it is quite easy to learn and for developers it can help them better understand the potential of their applications going forward. This is because you can gather a lot of the necessary information straight from the application itself. It has more functionality for testing than comparable programs which, together with the ease of learning it, makes it a compelling choice.

3. What technologies does Coded UI support?

There are multiple applications of Coded UI and the interviewer's organisation likely uses it for at least one of these. This is why it is a good idea to research your potential employer in advance, as you can then determine what their most likely use-case is. To answer this question, it is typically sufficient to list some examples without going into extra detail, as the interviewer can always ask you to elaborate further if necessary.

Example answer: There are many examples of supported technologies, and I am familiar with a few. These would be web servers like SOAP and ASPX, in addition to HTML 5, HTML and Silverlight. There is also the Windows Presentation Foundation. Coded UI works well with most of these in my experience, although it is always interesting to discover more.

4. What kinds of data are usable for Coded UI Testing?

This is another example of a question which tests your working knowledge. There is only one correct answer, and the list of compatible data is relatively short, so you can mention all of them. Try to list these for the interviewer, and you can also supplement this with extra information that demonstrates your relevant knowledge.

Example answer: There are five different kinds of compatible data, each of which corresponds to its own data-driven testing type. There are also four steps involved in this data-driven testing. The compatible types are Test cases in TFS, XML, CSV, SQL and Excel.

5. Is a framework always necessary when using Coded UI?

Interviewers often like to ask questions like these to determine the limits of your knowledge. It is also a subtle question and the answer can demonstrate to the interviewer how familiar you are with Coded UI. Although you could answer this with one word, it is better to justify your answer and take advantage of the opportunity to prove your knowledge and experience.

Example answer: No, it is not always necessary to use a framework. Although this is possible, it is often still a good idea to take advantage of them. Frameworks are easier to maintain and it is simpler to upgrade them with new components when necessary. The downside is that excessive usage can dull creativity in testing.

6. Is it possible to reach total automation?

Automation is a useful tool and interviewers may wish to determine how much you rely on it. Consider the pros and cons of both pursuing and achieving complete automation. This allows you to give a nuanced answer, which shows that you have experience and know when to use certain tools. With a question like this, you can give some more detail in your answer.

Example: While this is a possibility, it would be very difficult to achieve 100% automation in practice. Moreover, there are many cases where utilising automation would bring little or no value, especially in relation to the effort necessary to implement it. For instance, there may be scenarios that represent rare occurrences or edge cases. For these, automation would add little to the software in terms of value. The benefit of automation is when you have critical cases where speed and low error rates are very important.

7. Can you tell me what the test builder is?

The test builder is a useful tool within Coded UI. An interviewer may ask you about it to see how familiar you are with the various tools available to you. This can be indicative of your familiarity and working experience with Coded UI. You can answer this by briefly stating what it is and giving a few details about its uses.

Example answer: This is a tool that you can use in Coded UI. It has four different options from which to choose. These are the options to 'record', 'crosshair', 'generate code' and 'show recorded steps'. Each of these allows you to implement and analyse various areas of the overall code with which you are working. For example, 'crosshair' derives its name from the fact that it allows you to see the controls for a specific part of the code for the purposes of functionality testing.

8. What do you do to get the most out of Coded UI?

A more open-ended question like this one is often more likely later in the interview. This is an opportunity to show the interviewer how experienced you are with Coded UI. Try to think of some best practices or tips that you feel make your work easier and share them with the interviewer. Additionally, if you get the job, then the interviewer may know which areas you could benefit from support on, based on your answers.

Example answers: There are a few things that I find make my work with Coded UI easier. One of these is to always use the test builder whenever possible. I also try to vary the methods I use and remember their names. This is because relying on the default alone can cause some testing problems in my experience. Another useful tip would be to re-record your test methods to make sure they are up-to-date.

Tips for answering questions

Here are some additional tips for answering Coded UI interview questions and others:

  • Look at situational questions. Interviewers often like to ask situational questions, which involve a hypothetical situation and asking you to explain how you would handle it. Research some common examples in advance to prepare.

  • Give examples. Wherever possible, justify your answers with examples from your work experience. If you lack this experience, then any relevant example is acceptable, including from your time in education.

  • Practise. Prior to your interview, get a friend or colleague to conduct a mock interview to allow you to practise. Ideally, this individual is going to be working in the same industry as you.
