How are you promoting this?

This seems to be the most mature library for running docker integration tests in .NET, but I find nobody is talking about this in the .NET Community.

Hello, I've been talked about this a year ago on a big conference DotNext 2018 in Moscow (https://2018.dotnext-moscow.ru/en/2018/msk/talks/3ymcx4gfcesekaw2qwgeas/). Also I am constantly pushing this approach on my projects and inside my company. Apart from that there is no other efforts. Do you think it is worth to promote?

[jzabroski]

Yes. TestContainers-DotNet is a total disaster. You seem to be way ahead of them and the only disadvantage you have is you don't have the TestContainers brand name recognition.

Love the use of async/await - it's brilliant and simplifies things like stupid things people do in docker-compose.yml files, like using https://github.com/ufoscout/docker-compose-wait so that an ASP.NET Core web server docker container running entity framework waits for a database server to start and pass health check before starting the web server container.

Yeah, waiters are very useful feature, but there is another one called containers re-usage that allows you to run your containers only after first tests execution and then instead of re-creating them for each test run the library just can drop all the data. That saves lots of seconds if you have such containers like Elasticsearch (~30 secs to start) or MSSQL (~40 secs to start).

Yes, and the ability to destroy a container to simulate a crash.

When you really think about it, there is no reason you can't replace docker-compose with TestEnvironment.Docker - it just needs a way to wake back up on system restart. The way docker-compose does this, I think, is through using a yaml config file. Maybe it has other tricks, but the argument for docker-compose is it can "just go" on startup. But that is not that a clever trick. Just wrap TEstEnvironment.Docker referencing project in TopShelf and expose as a Windows Service.

@Deffiss Curious if your recent PR #13 was provoked by this comment 🗡

[Deffiss]

Well, if somebody from community is interested in my work then it always motivates me..

I mentioned it to David Fowler at Microsoft since he just created Micronetes
