I get this error when I run mvn test on the project.
I have Docker CLI installed. What is the fix here?

@deepng, some tests require Docker.
To run tests, pre-install docker and npx, then run ./mvnw test.
Alternatively, build without tests using ./mvnw clean install -DskipTests.
I'll keep this issue open as a reminder to update the README docs.
