spanner-golang-test

A golang unit test example for google spanner, using google spanner emulator provided by cloud-spanner-emulator.

Hopefully, it helps you. I create this since I can not find the straight-forward example for golang.

Setup

You need spanner emulator running:

docker run -d -p 9010:9010 -p 9020:9020 gcr.io/cloud-spanner-emulator/emulator:1.0.0

Test

Run make test. The test uses golang test suite, which will do:

1. Create spanner instance on google spanner emulator
2. Create spanner db on google spanner emulator
3. Execute singer-table-ddl
4. Truncate singer table before test
5. Execute test(s)
6. Drop database and instance on google spanner emulator

Database creation/drop is done as suggested by in cloud-spanner-emulator README.
