+### Grouping tests
+
+Sometimes it is useful to group related tests so they can be easily run together without running the entire test suite.
+Each test group is in a subdirectory of `tests`.
+For example, `tests/ca/local.mk` defines a `ca` test group for content-addressed derivation outputs.
+
+That test group can be run like this:
+
+```shell-session
+$ make ca.test-group -j50
+ran test tests/ca/nix-run.sh... [PASS]
+ran test tests/ca/import-derivation.sh... [PASS]
+...
+```
+
+The test group is defined in Make like this:
+```makefile
+$(test-group-name)-tests := \
+  $(d)/test0.sh \
+  $(d)/test1.sh \
