Programming in C# with Unit Testing

Course Description

This SkillDynamo course develops practical, role-relevant capability in developing testable C# applications with clean design, unit-testing frameworks, test doubles, coverage, refactoring, automation, and reliable delivery. The learning path progresses from essential concepts and planning to implementation, validation, troubleshooting, and operational use.

Learners work through realistic scenarios, guided demonstrations, applied exercises, and evidence-based reviews. Every topic is connected to workplace responsibilities, common risks, quality controls, and measurable outcomes.

The course helps professionals make informed decisions, identify failure points, communicate results, and create an actionable improvement plan for future projects.

What You Will Learn

• Explain unit-testing purpose, test boundaries, arrange-act-assert, test naming, independence, determinism, and fast feedback
• Design C# classes with dependency injection, small responsibilities, clear contracts, and observable behavior
• Create assertions, setup and teardown, parameterized tests, theories, fixtures, test data builders, and exception tests
• Test normal, boundary, invalid, null, error, state-transition, and asynchronous behavior
• Use mocks, stubs, fakes, spies, interfaces, adapters, and controlled dependencies without over-mocking
• Refactor legacy code, isolate seams, remove duplication, improve readability, and preserve behavior through tests
• Measure coverage thoughtfully, identify untested risk, automate tests in builds, and establish quality gates
• Diagnose flaky tests, maintain suites, document intent, review failures, and improve testing strategy
