Cannot run lesson-2 tests

[MrSamsa42]

I am not able to run the tests associated with lesson 2. See terminal output below. Environment is Windows 10, Node 12.10

npm run test-schema

intro-to-gql@1.0.0 test-schema C:\Users\mrsam\Projects\Education\intro-to-graphql
GQL_LESSON=lesson-2 npm test -- -t lesson-2

'GQL_LESSON' is not recognized as an internal or external command,
operable program or batch file.

It took forever, but I found the solution. Stack Overflow to the rescue (again): https://stackoverflow.com/questions/9249830/how-can-i-set-node-env-production-on-windows

So, change the script in the package.json file to:
"test-schema": "set GQL_LESSON=lesson-2 && npm test -- -t lesson-2"

It should be:
"test-schema": "cross-env GQL_LESSON=lesson-2 npm test -- -t lesson-2"
