For those not aware, Shift Left[1] is (at this point) an old term that was coined for a specific use case, but now refers to a general concept. The concept is that, if you do needed things earlier in a product cycle, it will end up reducing your expense and time in the long run, even if it seems like it's taking longer for you to "get somewhere" earlier on. I think this[2] article is a good no-nonsense explainer for "Why Shift Left?".

So “shift left” is roughly equivalent to “tests first” or “TDD”?

More broadly it includes moving activities that are normally performed at a later stage so that they are earlier in the process. The idea is that defects found later in the process are more costly.
