Run Unit Tests with Spanner

You are helping run unit tests that require the Spanner emulator.

Instructions

Follow these steps to run unit tests with Spanner:

1. Check if the Spanner emulator environment is already configured:

   • Check if SPANNER_EMULATOR_HOST and STORJ_TEST_SPANNER environment variables are set
   • Use bash to check: echo $SPANNER_EMULATOR_HOST and echo $STORJ_TEST_SPANNER

2. If environment variables are already set:

   • Inform the user that the Spanner emulator environment is already configured
   • Show the current values of the environment variables
   • Ask the user which test they want to run (package path and optional test name)
   • Run the test directly using: go test -v ./package/path -run TestName

3. If environment variables are NOT set:

   • Inform the user that the Spanner emulator needs to be started
   • Start the Spanner emulator in the background: spanner_emulator --host_port 127.0.0.1:10008
   • Save the emulator process ID for cleanup later
   • Ask the user which test they want to run (package path and optional test name)
   • Run the test with environment variables:

     SPANNER_EMULATOR_HOST=localhost:10008 \
     STORJ_TEST_SPANNER=spanner://127.0.0.1:10008?emulator \
     go test -v ./package/path -run TestName
     

   • After the test completes, ask the user if they want to stop the emulator or keep it running for more tests
   • If they want to stop it, kill the emulator process

4. Report test results:

   • Show the test output
   • Indicate whether tests passed or failed
   • If tests failed, offer to help investigate the failures

Common test paths

Some common test paths in the Storj codebase:

• ./satellite/metabase - Metabase tests
• ./satellite/metainfo - Metainfo API tests
• ./satellite/satellitedb - Database tests

Notes

• The standard Spanner emulator port is 127.0.0.1:10007 but flag --host_port 127.0.0.1:10008 can be used to change it.
• If the emulator is started, it will continue running until explicitly stopped
• Multiple tests can be run with the same emulator instance
• The emulator process runs in the background and should be cleaned up when done
