+# The 'test/_global' folder is a special test folder that is not tied to a single feature.
+#
+# This test file is executed against a running container constructed
+# from the value of 'color_and_hello' in the tests/_global/scenarios.json file.
+#
+# The value of a scenarios element is any properties available in the 'devcontainer.json'.
+# Scenarios are useful for testing specific options in a feature, or to test a combination of features.
+# 
+# This test can be run with the following command (from the root of this repo)
+#    devcontainer features test --global-scenarios-only .
+
+set -e
+
+# Optional: Import test library bundled with the devcontainer CLI
+source dev-container-features-test-lib
+
+echo -e "The result of the 'color' command will be:\n"
+color
+echo -e "The result of the 'hello' command will be:\n"
+hello
+echo -e "\n"
+
+# Feature-specific tests
+# The 'check' command comes from the dev-container-features-test-lib.
+check "check purple is my favorite color" bash -c "color | grep 'my favorite color is purple'"
+check "check I am greeting with 'Greetings'" bash -c "hello | grep 'Greetings, $(whoami)'"

+
+# Report result
+# If any of the checks above exited with a non-zero exit code, the test will fail.
