+# This test file will be executed against an auto-generated devcontainer.json that
+# includes the 'color' Feature with no options.
+#
+# For more information, see: https://github.com/devcontainers/cli/blob/main/docs/features/test.md
+#
+# Eg:
+# {
+#    "image": "<..some-base-image...>",
+#    "features": {
+#      "color": {}
+#    },
+#    "remoteUser": "root"
+# }
+#
+# Thus, the value of all options will fall back to the default value in the
+# Feature's 'devcontainer-feature.json'.
+# For the 'color' feature, that means the default favorite color is 'red'.
+#
+# These scripts are run as 'root' by default. Although that can be changed
+# with the '--remote-user' flag.
+# 
+# This test can be run with the following command:
+#
+#    devcontainer features test    \ 
+#               --features color   \
+#               --remote-user root \
+#               --skip-scenarios   \
+#               --base-image mcr.microsoft.com/devcontainers/base:ubuntu \
+#               /path/to/this/repo
+
+set -e
+
+# Optional: Import test library bundled with the devcontainer CLI
+# See https://github.com/devcontainers/cli/blob/HEAD/docs/features/test.md#dev-container-features-test-lib
+# Provides the 'check' and 'reportResults' commands.
+source dev-container-features-test-lib

+# Feature-specific tests
+# The 'check' command comes from the dev-container-features-test-lib. Syntax is...
+# check <LABEL> <cmd> [args...]
+check "validate latex installation" latex --version | grep 'TeX Live'
+check "validate tlmgr installation" tlmgr --version | grep 'TeX Live'
+
+# Report result
+# If any of the checks above exited with a non-zero exit code, the test will fail.
