changelog/v0.17.7.md
PULUMI_TEST_MODE environment variable to
true in either the Node.js or Python SDK. This new mode allows you to unit test your Pulumi programs
using standard test harnesses, without needing to run the program using the Pulumi CLI. In this mode, limited
functionality is available, however basic resource object allocation with input properties will work.
Note that no actual engine operations will occur in this mode, and that you'll need to use the
PULUMI_CONFIG, PULUMI_NODEJS_PROJECT, and PULUMI_NODEJS_STACK environment variables to control settings
the CLI would have otherwise managed for you.
