Duration: 4 Days
Course Overview
This course will cover the fundamentals of automated testing, and its role/practice in a modern iterative, incremental development approach such as Scrum. Coverage will be included on test driven development philosophy, as well as on the use of test automation to support continuous integration and prevention of regression in multi-team/multi-developer projects.

Further information:
• The course will contain hands-on exercises based on tools and technologies used in the Microsoft suite of development environments and languages.
• Exercises will include:
– Using unit testing tools to practise TDD
– Exploiting mocking frameworks to achieve test localisation and isolation
– Using SpecFlow to author BDD tests, including writing test bindings
– Creating user interface tests using Selenium or Coded UI tests
COURSE PREREQUISITES
It is assumed that all attendees on the course have prior experience of software development in a Microsoft environment, and are happy to work using the C# language on a Visual Studio based development platform.
