The document outlines a Microsoft Developer Camp led by technical evangelists Nick Trogh and Jan Tielens, focusing on modern app development and agile methodologies. It includes hands-on labs, discussions on continuous deployment, application insights, and the benefits of using tools like Visual Studio Online and Azure. Additionally, it highlights various user plans, agile frameworks, and emphasizes the importance of unit testing for effective software development.
![ TDD is a robust way of designing software
components (“units”) interactively so that
their behavior is specified through unit
tests.
Whenever you are tempted to type
something into a print statement or a
debugger expression, write it as a test
instead.
Manual or automated testing is much
better for finding bugs.
Automated integration tests are much
better for detecting regression (things that
used to work but have unexpectedly stopped
working).

- 57. Visual Studio Test Explorer is designed to support developers and teams who incorporate unit testing in their software development practices. Unit testing helps you ensure the correctness of your program by verifying that the application code does what you expect it to do. In unit testing, you analyze the functionality of your program to discover discrete testable behaviors that you can test as individual units. You use a unit testing framework to create tests of those behaviors and to report the results of those tests.
