-Most of the testsuite is implemented in the file [`tests.sh`](/tests.sh).
-This script contains hundreds of separate test cases.
-Most of them are *snapshot tests* which compare `bfs`'s output to a known-good copy saved under [`tests`](/tests).
+The test harness is implemented in the file [`tests/tests.sh`](/tests/tests.sh).
+Individual test cases are found in `tests/*/*.sh`.
+Most of them are *snapshot tests* which compare `bfs`'s output to a known-good copy saved under the matching `tests/*/*.out`.
 
 You can pass the name of a particular test case (or a few) to run just those tests.
 For example:
 
-    $ ./tests/tests.sh test_basic
+    $ ./tests/tests.sh posix/basic
 
 If you need to update the reference snapshot, pass `--update`.
 It can be handy to generate the snapshot with a different `find` implementation to ensure the output is correct, for example:
 
-    $ ./tests/tests.sh test_basic --bfs=find --update
+    $ ./tests/tests.sh posix/basic --bfs=find --update
 
 But keep in mind, other `find` implementations may not be correct.
 To my knowledge, no other implementation passes even the POSIX-compatible subset of the tests:
 
     $ ./tests/tests.sh --bfs=find --posix
     ...
-    tests passed: 89
-    tests failed: 5
+    tests passed: 90
+    tests skipped: 3
+    tests failed: 6
