Create a patch file

Some Diffblue Cover commands take a patch file. The exact patch file you need depends on your setup, but here are some examples using git diff.

The variable DIFFBLUE_PATCH represents the name of your patch file.

For a patch containing commits newer than the project’s origin (i.e. the corresponding branch on the remote repository your local branch was created from)

git diff $(git rev-parse --abbrev-ref HEAD)...HEAD > $DIFFBLUE_PATCH

For a patch containing commits on your branch newer than those on the local copy of TARGET_BRANCH (e.g. where TARGET_BRANCH is develop)

git diff TARGET_BRANCH...HEAD > $DIFFBLUE_PATCH

For a patch containing commits on your branch newer than those on the remote host TARGET_BRANCH (e.g. where REMOTE is origin and REMOTE/TARGET_BRANCH is origin/develop)

git fetch REMOTE
git diff REMOTE/TARGET_BRANCH...HEAD > $DIFFBLUE_PATCH

For a patch containing only currently uncommitted changes

git diff > $DIFFBLUE_PATCH
