Phoenix Integration Tests

This project contains integration tests for phoenix's generated projects.

Running tests

To install dependencies, run:

$ mix deps.get

Then run the basic test suite (no dependencies on the database) with:

$ mix test

To run the test suite with tests that test a specific database, run:

$ mix test --include database:postgresql
$ mix test --include database:mysql
$ mix test --include database:mssql
$ mix test --include database:sqlite3

For convenience, there is also a docker-compose.yml file that allows for starting up all of the supported databases locally.

$ docker-compose up

This allows all tests to be run with the following command

$ mix test --include database

Or alternatively, with docker and docker compose installed, you can just run ./docker.sh.

How tests are written

In order to have consistent, repeatable builds, all dependencies for all phoenix project variations are listed in mix.exs and locked via mix.lock. If a dependency version needs to be updated, it can be updated with mix.exs or using mix deps.update <dep name>.

It is also important to note that dependencies are initially compiled with MIX_ENV=test and then copied to _build/dev_ to improve test speed. Therefore, dependencies should not be listed in mix.exs with an only: <env> option.
