Development Practices

• Test-first development. Code without unit tests will not be accepted.
• Refactor mercilessly; however, notify the list before making large, broad-reaching refactorings.
• Small methods (no more than 15 lines). Long methods will be collected and emailed to the list until a refactored solution is found.
• Use guard clauses.
• Write acceptance tests wherever possible.

TDD Standards (Unit Testing and Design)

These standards are ideals, and not necessarily the current state of the code

• No unit-testing of private methods. TDD implies it is unnecessary.
• Don't make methods public just so you can test them (see above)
• Use Constructor Dependency Injection where possible.
• Use Dynamic Mocks for Constructor Dependencies.
• Interface-first design is preferred (i.e. all Constructor Dependencies should be interfaces)
• DefaultXYZ as a name is a smell. What exact type of interface are you implementing?

Coding Standards

• Respect the brace style. Curly braces at the start of the line:

  public Class Foo
  {
                  public Foo()
                  {
                                  Console.WriteLine("Hello World!");
                  }
  }

• Use C# naming conventions: methods, properties, classes should all start with upper-case letters.
• Namespaces should be C# style. They should start with 'ThoughtWorks.CruiseControl.XYZ' where XYZ is the Visual Studio Project Name. Sub-namespaces should map to directories where source files are saved.
• One file, one class – unless the inner class is private.
• All member variables should be prefixed with an underscore (ie. _name).
• The ternary operator is fine as long as the conditions are very simple.
• Avoid assignment in conditionals – extract to method instead
• Avoid magic numbers, use a nested enum or an inner class with public const members instead.
• Use spaces after punctuation such as commas and spaces, in accordance with standard written grammar. For example, please include spaces after semi-colons, between equals signs and after keywords
