I can't test this code because it's legacy. I need to update the code to make it testable. How can I manage that, without breaking existing functionality? I'll need to write some tests, but... argh!

Brilliant talk. Thank you very much. Very useful.

This started off very basic and I thought it might have been the wrong talk to choose, but it quickly got into what the title describes and went into a good level of depth. Good presentation style and humour too!

For me, this was the best and most informative talk of the conference so far. Are the slides available anywhere?

I liked the solutions for common problems of adding tests to existing code. I’ll go home and refactor a little bit to add some important tests :-)

Great talk. Funny with some really nice examples in sample code that was easy to understand.

Nice examples of applying dependency injection and Liskov substitution to safely refactor less than optimal code and bring it to a testable ( but not necessarily optimal ) state. I enjoyed Katy's take on the topics, and her quirky ( and slightly geeky ) sense of humor!

Excellent talk with great, relatable and funny examples to show some common patterns encountered in legacy codebases.
