80%. Much beyond that and you get into a decreasing return on the investment of making the tests.
I think this is a good rule-of-thumb in general. But I think the best way to decide on the correct coverage is to go through uncovered code and make a conscious decision about it. In some classes it may be OK to have 30%, in others one wants to go all the way up to 100%. That's why I'm against having a coverage percentage as a build/deployment gate.
Bingo, exactly this. I said 80 because that's typically what I see our projects get to after writing actually useful tests. But if your coverage is 80% and it's all just tests verifying that a constant is still set to whatever value, then yeah, thats a useless metric.
God I fucking wish my projects were like this
The 80-20 rule is for everything. Don’t waste 80% of effort to get that last 20% of coverage.
