Problem with tests

hello, when I try running the next command I get an error if somebody can help please do. thanx in advance.

yaniv@Yanivs-Air mflix-js % npm test -t callbacks_promises_async.spec.js

server@1.0.0 test
jest --passWithNoTests

No tests found, exiting with code 0

I do not recall the above to be a test that has to be run.

Which lab or exercise are you trying to do?

Tests are scripts found directly under the test directory. They have file extensions .test.js. You do not specify .test.js when using npm test -t. The first test you are supposed to run correspond to the file test/db-connection.test.js and you are supposed to use the following command to run the test:

npm test -t db-connection
