It helps the user to point more than one method in a single call. It only contains public access modifier because everything in the interface is public. Here are a few best practices a team developing and testing software should follow to guarantee high-quality software. The process of mechanically opening a web application in a browser and carrying out some more operations automatically is known as “browser automation.”
The questions can help you conduct or give C# interviews effectively. In fact, the Devskiller Global Technical Hiring & Skills Report 2019 shows that programming languages are often tested with other technologies in their environment. A destructor is a special method in C# that is automatically called when an object is destroyed. It is used to free up any resources that the object may have been using, such as memory or files. Destructors are usually implemented in a class and are denoted by the keyword ~ followed by the class name.

The Array which comprises elements of type array is called Jagged Array. The elements in Jagged Arrays can be of various dimensions and sizes. Basic knowledge of computers, such as working with command-line, file systems, and installing applications such as compilers, interpreters, etc. For an object to be eligible for serialization, it has to implement the ISerialize Interface. When you do the opposite operation — start with a stream of bytes and use it to create an object — you call the process de-serialization.
If you are a recruiter looking for assistance in hiring C# developers for your team, get in touch with Turing. Turing helps you source, vet, and match the best developers from around the world. And if you are a C# developer looking for a senior position with a Silicon Valley company, now is the right time to apply. Tasks are easier to use and manage than threads, and they can also be used to provide more efficient resource utilization. Threads on the other hand, provide a lower level of abstraction and are used to execute code directly in the processor.
What are the differences between System.String and System.Text.StringBuilder classes?
An interviewer is likely to ask this question to get an understanding of how you approach problem solving and to gauge your knowledge of automated testing solutions. An interviewer might ask this question to get a better understanding of your technical capabilities and the types of projects you’ve worked on in the past. There are several testing methodologies, but not all of them can be automated – i.e exploratory testing. Here are some types that can be asked by the interviewer when it comes to automation testing interview questions. Accessibility and usability are two of the most important aspects of automation engineering.
- You will need to have some understanding of concepts like encapsulation, polymorphism, abstraction, inheritance, interfaces, etc., as C# is an object-oriented programming language.
- A test script is a code to perform a set of instructions on an application.
- Protected access specifiers are similar to private access specifiers because they cannot be accessed outside the class.
- Some languages like C++ can write unmanaged applications such as an application for accessing the low-level functions of the operating system.
- It controls the test script source code with a recorded history of changes to simplify the modification process.
- Modular Testing framework is built on the concept of abstraction.
However, once implemented, the team may discover that the testing technique is ineffective since the software is complicated and continually changing configuration and features. Manually configuring several environments for each combination or number of users is challenging. Automated technologies make it simple to construct this environment and conduct non-functional testing. Unless specifically trained to do so, automated testing is incapable of detecting and reporting UI issues.

The struct is a value type data type in C# that inherits from System.Value. These are used to store data structures and usually small quantities of data. Structs can use parameterized constructors, and they are declared with the struct keyword. When writing https://wizardsdev.com/en/vacancy/qa-automation-engineer-c/ 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. Classes have properties and methods, which are referred to as class members.
You’d use sealed modifiers to prevent deviation from a class. If you chose a sealed class to be a base class, you’d get a compile-time error. To land a six-figure C# job, you’ll have to perform well during the interview. Below, you’ll find some C# interview questions to practice, as well as their answers, so you can walk into your next interview with confidence. Whether you’re looking for an entry-level software development position or an experienced C# developer eyeing a new role, you’ll want to refresh your memory of the essential C# concepts.
Describe the difference between array and arraylist
The process of converting an object into a stream of bytes is called Serialization. For an object to be serializable, it should implement ISerialize Interface. De-serialization is the reverse process of creating an object from a stream of bytes. The Array which has elements of type array is called jagged Array. C# is an object-oriented, type-safe, and managed language that is compiled by .Net framework to generate Microsoft Intermediate Language.
This is useful in scenarios where you need to process a portion of a large array and want to avoid memory overhead caused by creating new subarrays. Another major difference is that dispose() method is explicitly invoked by the user and finalize() method is invoked by the garbage collector, just before the object is destroyed. The term File Handling refers to the various operations like creating the file, reading from the file, writing to the file, appending the file, etc.
CLR directly executes such code by using managed code execution. Any language written in the .NET framework is considered to be managed code. Multicasting delegates allow users to invoke multiple callbacks. It can refer to multiple methods and functions having the same signature at one time. As the Main() method is called by the runtime, it should be defined as public. C# is a high level programming language whereas C++ is a low level programming language.
Read and write are the two operations used in file handling. A jagged array, also called an array of arrays, is a multidimensional array that consists of other arrays of different sizes. We can change the value or reuse the variable as many times as we like. The CLR is a virtual machine component of the .NET Framework.
