Unit Testing for C# Developers
The Unit Testing for C# Developers course teaches developers to create automated tests using xUnit, MSTest, or NUnit frameworks within .NET, enabling early bug detection and improved code quality. Designed for C# developers with 1+ years of experience, it solves the critical pain point of unstable applications by enforcing test-driven development (TDD) practices. Microsoft reports that 85% of professional developers now use unit testing to reduce post-deployment defects.
This course prepares learners for the Microsoft Certified: Azure Developer Associate certification (Exam AZ-204), covering key testing objectives in solution development. Koenig Solutions delivers official vendor-authorized courseware with Guaranteed-to-Run dates, ensuring hands-on mastery. Graduates gain confidence in building resilient cloud applications aligned with industry best practices.

Course Overview
The Unit Testing for C# Developers course by Microsoft is designed to equip software engineers with essential skills in creating reliable, maintainable code through automated testing practices. This training targets developers preparing for roles such as Software Developer, Quality Assurance Engineer, or .NET Application Developer, particularly those aiming to validate business logic in enterprise applications. While no specific certification exam is currently tied directly to unit testing alone, this course supports broader Microsoft developer certifications like the retired Exam 70-483: Programming in C#, and aligns with modern development standards emphasized in current Azure and .NET credentials. With software development jobs projected to grow 16% from 2024 to 2034—much faster than average—mastery of unit testing is increasingly critical, especially given that over 75% of enterprise .NET teams now require test coverage in their CI/CD pipelines.
This Microsoft-led course covers core technologies including xUnit, MSTest, NUnit, .NET SDK, Visual Studio Code with the C# Dev Kit extension, and integration with GitHub Copilot for AI-assisted test generation. Students engage in hands-on labs using the local development environment configured via the .NET CLI, where they build complete test projects from scratch alongside production code libraries. A key lab scenario involves implementing a PrimeService class using Test-Driven Development (TDD), writing failing tests first with `[Fact]` and `[Theory]` attributes, then iteratively refining the source code until all tests pass. Learners also explore best practices such as assertion techniques, data-driven testing, and structuring test classes using official Microsoft patterns, all within a realistic solution structure mirroring real-world .NET project organization.
By completing the Unit Testing for C# Developers curriculum, participants strengthen their readiness for Microsoft’s role-based developer certifications and improve employability in a competitive market where senior .NET developers earn $150K–$200K annually in the U.S. The course emphasizes industry-recognized testing frameworks and methodologies that enhance code quality and reduce regression issues in production systems. As a Koenig Solutions participant, you benefit from Guaranteed-to-Run scheduling and access to official Microsoft courseware, ensuring structured, instructor-led mastery of unit testing principles. Upon completion, developers are positioned to advance into senior engineering or SDET roles, contributing to high-quality, cloud-native applications on the Azure platform with confidence in their testing rigor.
