+# Synopsis:
+# Test the track's exercises.
+# 
+# At a minimum, this file must check if the example/exemplar solution of each 
+# Practice/Concept Exercise passes the exercise's tests.
+#
+# To check this, you usually have to (temporarily) replace the exercise's solution files
+# with its exemplar/example files.
+#
+# If your track uses skipped tests, make sure to (temporarily) enable these tests
+# before running the tests.
+#
+# The path to the solution/example/exemplar files can be found in the exercise's
+# .meta/config.json file, or possibly inferred from the exercise's directory name.
+
+# Example:
+# ./bin/test
+
+exit_code=0
+
+# Verify the Concept Exercises
