Catching the commit which introduced a bug with git-bisect

Manually marking commits

• git bisect start HEAD <SHA-1> --
• This marks <SHA-1> as the first place we know there isn't bugs, and HEAD as the place where we know the bug is present. We will start at the midway of all the commits
  • git bisect good will mark the commit to not have bugs and move to the next section
  • git bisect bad will mark the commit to have bugs
• git bisect reset

Marking commits with run

• git bisect start HEAD <SHA-1> --
• git bisect run <cmd>
• git bisect reset

Example

• git bisect start HEAD HEAD~10 --
• git bisect run yarn test
• git bisect reset
