Overview of this book

Traditionally associated with Windows desktop applications and game development, C# has expanded into web, cloud, and mobile development. However, despite its extensive coding features, professionals often encounter issues with efficiency, scalability, and maintainability due to poor code. Clean Code in C# guides you in identifying and resolving these problems using coding best practices. This book starts by comparing good and bad code to emphasize the importance of coding standards, principles, and methodologies. It then covers code reviews, unit testing, and test-driven development, and addresses cross-cutting concerns. As you advance through the chapters, you’ll discover programming best practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. You’ll also explore API design and code quality enhancement tools, while studying examples of poor coding practices to understand what to avoid. By the end of this clean code book, you’ll have the developed the skills needed to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

Testing exception handling

Testing exception handling with different types of tests involves testing the handling of exceptions in different contexts of an application. Here’s how to test exception handling with unit tests, integration tests, and end-to-end tests:

  • Unit tests: Unit tests are used to test the behavior of individual components of an application. When testing exception handling with unit tests, we can create tests that verify that expected exceptions are thrown in response to certain inputs.

    For example, we can test a method that performs division by zero and ensure that it throws a DivideByZeroException exception when zero is passed in as a denominator.

  • Integration tests: Integration tests are used to test the interactions between different components of an application. When testing exception handling with integration tests, we can verify that components are handling exceptions properly when they interact with one another.

    For example, we can test a system...
