Automate Testing: Gitlab, Dotnet

I always want to test my .NET based application on my personal Gitlab based repo. But since, my old project is too much a mess to do the effort for. So, when we got to rewrite the whole project, I was happy to get my experience on Unit Testing with automation of CI. I still don’t do much of CD as my development environment is still limited to development only.

So, I read about it and using Gitlab’s YML configuration, I was able to run the xUnit based Unit Test easily. It was simple too, call a MS/dotnet docker as base image, then dotnet build and later dotnet test .

But the problem arise when I have to connect to database and then I cannot get SQLCMD command to work, though I get the MS SQL Server based service to started, but until that command runs which is not present in ms dotnet docker, I cannot reload my database easily. For that I have to write code to bootstrap and create database. So, I try to search for it, and after lot of fail attempt and surprisingly no example of how to use database with YML configuration other than basic example for Mysql or Microsoft’s own docker file example. I found no info on this.

So, I decide to create a new docker image, I want to do it my way. So, I use a Ubuntu Docker image, install dotnet 2.2 on that image with mssql-cmd tools. I didn’t install MS SQL Server as I can use that as service. So using this docker image, I get my Unit testing working. This help me automate my project workflow and help me get best out of me, without need to worry about hidden errors.

My this docker image is available for anyone need it at Docker hub:
