And for newbies, you might even decide to pursue it as a career! Read this article to know more about where to learn C# programming. As a developer, there are things you have to learn about C# programming. In this entry, let’s take a look at its basic attributes and why it remains so popular. A nullable type can contain a value, or it can be undefined.

C# Tutorial

C# has its roots in the C family of programming languages and shares many of the same characteristics as those found in C and C++, as well as in Java and JavaScript. In C#, memory address pointers can only be used within blocks specifically marked as unsafe,[76] and programs with unsafe code need appropriate permissions to run. An unsafe pointer can point to an instance of an unmanaged value type that does not contain any references to objects subject to garbage collections such as class instances, arrays or strings. Code that is not marked as unsafe can still store and manipulate pointers through the System.IntPtr type, but it cannot dereference them. The C# programming language was designed by Anders Hejlsberg from Microsoft in 2000 and was later approved as an international standard by Ecma (ECMA-334) in 2002 and ISO/IEC (ISO/IEC 23270) in 2003.

  • Also, the Unity game engine―one of the most popular game engines today―is built using C++ and C#.
  • This declares the class member method where the program begins execution.
  • Language integrated query from Microsoft may also make C# preferable for data analysts.
  • The language does not place constraints on what you can do.
  • That is, sometimes we want to create a superclass that only defines a generalized form that will be shared by all of its subclasses, leaving it to each subclass to fill in the details.

The properties and behaviors of an object differentiate it from other objects of similar type and also help in classifying/grouping the objects. It is widely used as a software development methodology to create applications that are more strong and can easily scale. C# is a user-friendly language that offers a structured approach to problem-solving. It provides a wide range of library functions and data types to work. The rare attribute that most common languages fail to accomplish. Object-Oriented Programming (OOP) offers efficiency and flexibility, such as building Applications Performance Management(APM) software.

Language Integrated Query (LINQ)

XOR is a common boolean operator and has nothing unique to it in C#. I suggest reading a little about boolean algebra to learn what it is used for with 1 bit,
then check what you get when you do (a c# for web development XOR b) XOR b with any two numbers or characters a and b. Variables are named containers that store values of different types. To declare a variable in C#, you need to specify its type and name.

C# has a built-in garbage collector, it allows for using code interfaces, and is object-oriented by design. At the time this book was written, it was unknown as to what the popularity of C# would be, but it is a good bet that this will become a very popular language for a number of reasons. One of the key reasons is Microsoft and the promises of .NET. Since tech giant Microsoft created C#, there is no question of why it has massive community support. In the world of software development, having a community is essential. Programming languages aren’t a platform or service with a dedicated helpline or IT support.

In C#, classes support polymorphism, inheritance and also provide the concept of derived classes and base classes. C# is an object-oriented programming language, which makes development and maintenance easier. In contrast, with procedure-oriented programming languages, managing code becomes difficult as project size grows. If you have experience with these or other programming languages, learning C# is a piece of cake. To put it into perspective, C# is not as easy to learn as Python but not nearly as hard as C.

The code is type safe can only access memory locations that it has permission to execute. C# (C-Sharp) is a programming language developed by Microsoft that runs on the .NET
Framework. There aren’t any complex or unstructured language features in C#, which makes it distinct from C, wherein you have to take care of complex memory-management in the code. In this article, you will learn about what C# is and what kind of software applications we can build using C# language. I dont know whether people at Microsoft actually used Bob in their daily jobs. Many of its products have already had portions rewritten in C#.

C# programming can save you time

Developers, especially full-stack developers, prefer C# programming language. Not only can it save development time, but it also has a low learning curve. Developers spend less time learning C# compared to other programming languages. Its simplicity and easy-to-use features aid new developers and those who want to learn a new language. In addition to the time you can save during project development, you’ll also spend less time learning C# as opposed to the more difficult programming languages out there.

what is C#

For mobile developers, it can be used virtually on any modern mobile device or console using cross-platform technology like Xamarin. So, if you want to break into the game development industry, or join the bandwagon of Virtual Reality, then you can leverage the programming language’s potential. With a growing interest in learning C# and a foundation rooted deep within the Microsoft platform, the future looks bright for this particular programming language.

What is C#?

If Microsoft can fulfill its promise with .NET, then C# should have a long, robust life, and C# developers should become as demanded as C++ and Java programmers. Many people believed that there was no need for a new programming language. Java, C++, Perl, Microsoft Visual Basic, and other existing languages were believed to offer all the functionality needed. C# is a new language created by Microsoft and submitted to the ECMA for standardization. This new language was created by a team of people at Microsoft led by Anders Hejlsberg .

The keys to an object-oriented language are encapsulation, inheritance, and polymorphism. Encapsulation is the placing of functionality into a single package. Inheritance is a structured way of extending existing code and functionality into new programs and packages. Polymorphism is the capability of adapting to what needs to be done. Features such as exception handling, garbage collection, extensible data types, and code security are features that are expected in a modern language.

C# Object Class

When building C# applications, developers can use type declarations to create new types. A type declaration defines the name and members of the new type. Type declarations are based on six of the subcategories available to value and reference types. They include struct types, enum types, tuple value types, class types, interface types and delegate types. In the C programming language family, the bitwise OR operator is “|” (pipe). Again, this operator must not be confused with its Boolean “logical or” counterpart, which treats its operands as Boolean values, and is written “||” (two pipes).

What is Test Strategy? Types of strategies with examples

Once the test strategy has been written, we cannot modify it, and it is approved by the Project Manager, development team. In this section, we are going to understand the test strategy documentation, which is an integral part of testing documentation. When a particular problem is identified, the programs are debugged and the fix is applied to the program. To make sure that the fix works, the program will be tested again for that criterion. Regression tests will reduce the likelihood that one fix creates some other problems in that program or in any other interface. So, a set of related test cases may have to be repeated, to test whether anything else is affected by a particular fix.

test strategy definition

Before any testing activities begin, the Test strategy document can distribute to the entire testing team. In Software Engineering, software release goes through Test Strategy documents from time to time to map the progress of testing in the right direction. When the release date is close many of these activities will be skipped, it is desirable to discuss with team members whether cutting down any particular activity will help for release without any potential risk. A different organization has their unique processes and standards to manage these documents. For example, some organization include test strategy facts in Test Plan itself while some organization includes strategy as a subsection within the testing plan.

Put simply, the test strategy document is a well-written document that outlines the precise methodology and goals of the testing project. It is an important document for QA teams and is based on actual business requirements. The test strategy document addresses all your questions about what you want to achieve and how you plan to do it in the project. A high-level document is used to validate the test types or levels to be executed for the product and specify the Software Development Life Cycle’s testing approach is known as Test strategy document. Here test teams follow a predefined quality standard (like ISO25000), checklists or simply a set of test conditions.

Risk in the Test Strategy

By following these steps diligently, we equip ourselves for a successful testing process, ensuring that our software is of the highest quality before it reaches the users. A test summary is a frequently overlooked yet essential aspect of a strategy document. It is the final crux of the entire approach & aspects of the strategy, which is a handy piece of information for consumers and stakeholders. It thus requires the distinct skill of packing more information in fewer words. Moreover, summarization may also include the visual representation of data (like pie charts, bar graphs, etc.) for encapsulating extensive numeric data in a more understandable and precise manner.

Throughout this process, you’ll strive to unify your teams, increase their collaboration, and remove the complexity from everything they do by standardizing tools and processes to the greatest possible extent. At the process layer, your teams will focus on establishing consistent, accurate measurement of your testing activities so that they can provide useful feedback to stakeholders. They will also develop your strategy in ways that help accelerate and prioritize testing. Once you’ve clarified the three levels of testing activities your teams will perform, you can begin to define your testing practice. They execute API and contract tests, test microservices and databases, and validate your features and functions. Some of the components can be virtualized, but everything is tailored to the needs of the team.


Another prominent advantage of incorporating the strategy in the primitive stages of software is the scope of using the trial-and-error method with fewer stakes involved. Furthermore, it allows testers to record the entire product history and organizes the error-handling process. This blog will examine a list of software testing techniques, attempting to help our readers with determining which ones best suit the desires of the software under test.

If your organization is serious about achieving high-speed releases, you need to optimize and orchestrate quality across teams, projects, and applications. Once you’ve determined the components of your testing strategy, focus on building your tooling strategy. A modern tool strategy should be driven by specific objectives and be capable of fulfilling many different requirements. Unlike a test plan, a test strategy is also a relevant document on the organizational level since it has a holistic reference to the testing methodologies taken by the organization.

Agile testing encompasses the same test types that testing teams have become accustomed to using in the testing cycle. The difference is that in agile testing, teams must perform these tests more often within a shorter period. A test strategy document outlines the overall approach for testing software, including scope, objectives, resources, and methods. It ensures efficient and effective testing to improve software quality and meet user expectations.

  • Another term that is often mentioned along with “test strategy” is of “test approach”.
  • However, a test plan is a dynamic document that needs to remain flexible and changeable throughout the entire duration of the project.
  • It is even better to describe the enlisted risks based on some general points like their effects, probability, and root causes.
  • Test charters are developed based on the existing features and functionalities.

AWS-based platform empowered with BI that enhances the efficiency of marketing activities and optimizes marketing campaigns. Defect or bug management details how bugs and errors will be reported, including channels, chains of command, reporting, and solutions. The next part describes the nature and availability of the test environment as well as how it will be configured to attain the best results.

That alignment helps to avoid wasted time end effort by performing the right tests for the right reasons. Tricentis NeoLoad offers a suite of powerful features designed to elevate performance testing strategy and maximize ROI. The test strategy document is accountable for consistency in the process of testing. It is a pretty rigid document but has an enormous scope of flexibility at the microscopic level. With such intricacies, designing the strategy becomes a seemingly formidable task. However, if ideal considerations, proper procedure, and expert recommendations are followed tenaciously, this complex task can become surprisingly effortless.

The data restoration plan should also entail information about the essential contents of the backup. This strategy is created to ensure the product is compliant with industry or even legal standards. An example of a process-compliant test strategy is the medical sphere where testing compliance is crucial to avoid getting into legal trouble. This section describes the software and hardware that will be employed to run various tests. To achieve the best results and create a realistic environment, companies use actual devices, browsers, and operating systems.

The military strategy defines the main objectives and general approach to dealing with a conflict. The tactical side involves how many people are needed to fight the battle, the types of weapons, the timing of the battles, and so forth. In API testing, teams will test the migration of microservice-based applications, APIs, and more. With service virtualization, teams will shift testing left and increase the frequency of tests and deployments.
