Karl Stolley believes it's never too early. Let's hear how he incorporates code quality in his courses.


Our discussion includes:



starting people off with good dev practices and tools
linting
html and css validation
visual regression testing
using local dev servers, including https
incorporating testing with git hooks
testing to aid in css optimization and refactoring
Backstop
Nightwatch
