pgtest

An example repository showing how to use Testcontainers to use stateful container dependencies in unit tests. In this case:

• Set up a postgresql database
• Use Flyway to initialize the database
• Run a SQL select test against the database

I tried to keep the dependencies to a minimum, and some of these could be replaced with other choices:

• Testcontainers
• Postgresql JDBC driver
• FlywayDB (optional, could be replaced)
• HikariCP connection pool (optional, could be replaced)

Apple Silicon on Rancher Desktop

For M1, M2, and M3 macs, testcontainers has trouble launching using Rancher Desktop, but there is a RD workaround by setting an environment variable. First, run:

$ export TESTCONTAINERS_HOST_OVERRIDE=$(rdctl shell ip a show rd0 | awk '/inet / {sub("/.*",""); print $2}')

Then you can run the tests with:

$ mvn test
