Undoing a git bisect mistake

I'm doing a non-automated git bisect via command line. All is going well until I accidentally hit return on the wrong line in my command history, and rather than running the test, I run 'git bisect good' (or bad). Oops - I don't yet know if this commit should be marked good or bad, yet that's what I've done.

Can I undo the 'git bisect good' command, or make git forget the result of it, and go back and run the test for that commit?

From the git-bisect documentation:

> Bisect log and bisect replay

> After having marked revisions as good or bad, issue the following command to show what has been done so far: > $ git bisect log

>If you discover that you made a mistake in specifying the status of a revision, you can save the output of this command to a file, edit it to remove the incorrect entries, and then issue the following commands to return to a corrected state: > $ git bisect reset $ git bisect replay that-file

You can output a record of what was done using

$ git bisect log > bisect.log

Open that file in an editor and edit/remove the faulty line. Then you can replay it with

$ git bisect replay bisect.log

This is documented in git help bisect.
