test && commit || revert (TCR) - alternative to TDD or eccentricity?

test && commit || revert (TCR) is an alternative programming workflow to Test-Driven Development. If the tests pass changes are committed, otherwise all changes since the last successful test run are discarded. TCR is a workflow which encourages you to make changes in tiny steps (smaller commits). As a result, changes will get out into production faster. TCR “enforce” doing one change at a time. This leads to learn and create good refactoring approaches during a development.

Talk to me nicely - how to communicate your ideas and speed up your career

Are you frustrated because your ideas about new tools, frameworks, practices are not picked up by your fellow developers? Do you notice flaws in organization and your manager doesn't want to listen to you? You don't know why your mate behaves way he does? Are you angry because your code review remarks are considered nitpicky? 85% of your success depends on emotions. For some people sooner for some people later the way they handle other people will be a blocker for further development not only as developer/manager but also as a human. It is most probably that this will impact your career (promotion or even job lost).
