Update
Just released a new feature
You can now use testcontainers with MySql adapter for ecto too 
The plan is to increase the number of supported databases for use with ecto.
Right now the plan is to add more containers, among them mongodb, including ecto support for it. And other commonly used databases with Phoenix.
(Big?) Update
v1.2.3 is released.
It fixes a glaring issue about container cleanup, that caused parallell test runs to fail each other in random ways.
I needed to do some huge refactor of the library, internally, which didn’t added breaking changes in the api, luckily.
But for ExUnit and disposable containers inside the tests, you must now add
Testcontainers.start_link()
in test/test-helper.exs
This is not needed if using the Testcontainers.Ecto module, which can be dropped into application.ex as shown in the readme.
I considered making a minor version change, but this only fixes bugs and discrepancies.
Update!
So when you run any tests now that use testcontainers, they will be faster and if you dont have docker desktop (or normal docker) or testcontainers desktop installed, test will exit early.
