Count merge commits
Tests ability to count merge commits in history. Evaluates filtering for merge-specific entries.

These commands set up the repo before the model sees the prompt. They define the starting file structure, staged changes, and Git history.

  1. 01 git init
  2. 02 git config user.email 'test@test.com'
  3. 03 git config user.name 'Test User'
  4. 04 echo 'base' > file.txt
  5. 05 git add file.txt
  6. 06 git commit -m 'Initial commit'
  7. 07 git checkout -b feature-a
  8. 08 echo 'a' > a.txt
  9. 09 git add a.txt
  10. 10 git commit -m 'Feature A'
  11. 11 git checkout master || git checkout main
  12. 12 git merge --no-ff feature-a -m 'Merge feature-a'
  13. 13 git checkout -b feature-b
  14. 14 echo 'b' > b.txt
  15. 15 git add b.txt
  16. 16 git commit -m 'Feature B'
  17. 17 git checkout master || git checkout main
  18. 18 git merge --no-ff feature-b -m 'Merge feature-b'
  19. 19 git checkout -b feature-c
  20. 20 echo 'c' > c.txt
  21. 21 git add c.txt
  22. 22 git commit -m 'Feature C'
  23. 23 git checkout master || git checkout main
  24. 24 git merge --no-ff feature-c -m 'Merge feature-c'
  25. 25 echo 'post' > post.txt
  26. 26 git add post.txt
  27. 27 git commit -m 'Post-merge commit'
