Debezium connector spanner

Prerequisites

need to set google credentials file path
export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/service-account-file.json"

or set connector config parameter googleApplicationCredentialsFile

Tests

Run Unit tests

mvn test

Run coverage check

mvn clean test jacoco:report -P test-coverage

• Coverage report for unit tests is available at ${module.path}/target/site/jacoco/index.html

Integration tests

Run the full IT suite against the local Spanner emulator (default, no real GCP project needed):

mvn clean verify

Run the full IT suite with tests annotated @RealSpannerCompatible (e.g. MutableKeyRangeIT) executed against a real Cloud Spanner instance instead of the emulator, while every other IT class still runs against the emulator in the same command:

mvn clean verify \
  -Dspanner.test.real=true \
  -Dgcp.spanner.project.id=YOUR_PROJECT \
  -Dgcp.spanner.instance.id=YOUR_INSTANCE \
  -Dgcp.spanner.credentials.path=/path/to/key.json   # or -Dgcp.spanner.credentials.json=<inline JSON>

Set -Dspanner.test.real=false (or omit the property) to keep @RealSpannerCompatible tests on the emulator as well — this is the preferable way to run the suite once the emulator supports MUTABLE_KEY_RANGE change streams; until then those tests are reported as skipped (not failed) when run without -Dspanner.test.real=true.
