At this point, git start checking and it will let you know how many
remaining commits to check and which commit it is checking now (git
will choose the commit at the middle of your selected range at the
beginning)
Bisecting: 2 revisions left to test after this (roughly 1 step)

Yeah, git automatically checks out the commit Add container. Our job
is run our code and let git know if this commit contains bad code or
not. In our case, this is a bad commit, so we let it know that it is bad.

Yeah, now git knows this commit is bad, so it does not need to check
all the commits later than this commit. You have just reduced the
search range to a half (binary search)
Bisecting: 0 revisions left to test after this (roughly 0 steps)

Automated debugging with git
- 1. Automated debugging with git Amit Nijhawan
- 2. 2 What is git bisect? ● Use binary search to find the commit that introduced a bug. So what does that mean?
- 3. 3 Divider Slide The basic git bisect workflow
- 4. 4 Basic bisect commands: start, bad, good $ git bisect start $ git bisect bad # Current version is bad $ git bisect good
- 5. 5 How to verify good and bad commit using bisect tool? First, we need to let git know that we are going to start bisect procedure: git bisect start Next, we will let git know which commit is bad, if the current commit is bad, you don't have to specify the hash: git bisect bad Then, we let git know which commit is surely a good one (in this case, it is the Initial commit, we have to specify the hash) git bisect good c1417d3
