I am currently working with a company that has a 40 million dollar contract that will be lost if the code is buggy and incomplete. We have just started writing unit tests. TDD is foreign to most of the team members. Most of the code is contained in the code behind of aspx pages. I am using selenium to write the unit test. Team members are getting frustrated because of the tight deadline; they feel they don't have the time to unit test. While this is going on the company has decided the team should use the agile methodology yet they have no training/mentoring so it is causing them more frustration and anxiety. We have a consultant telling them they must learn TDD and agile while at the same time they have an extremely tight deadline. The deadline will not budge. I want the team to be able to produce quality code within the timeline. At the point it is too late to eliminate the spaghetti code and lack of domain objects. I still want as much test coverage as possible. I am the go between the developers, an agile consultant and the management. Any ideas?
