Quick setup of Continuous Integration for .NET Core using Travis - CI. Very short

For some requests, I’m posting a very short squeeze of my previous article about setting up Continuous Integration, but "as a checklist for C #." At the same time added several alternatives to Travis.

Reading will take no more than 3 minutes, for whom it is interesting - I ask for cat.

Install the .NET Core SDK . Create a new repository and project.

dotnet new sln --name CIDemo dotnet new web --name web dotnet sln CIDemo.sln add web/web.csproj 

Add the .travis.yml file to the project root folder.

 language: csharp dotnet: 2.1.4 sudo: false env: global: - DOTNET_CLI_TELEMETRY_OPTOUT: 1 script: - dotnet build CIDemo.sln -c Release 

.travis.yml - Travis service file, contains environment settings, variables and commands. Documentation here

Login to Travis and give it access to your repository. Fill changes to the server.

Successful build:

And locally everything works for me Not a good build:

Add a test project

 dotnet new xunit --name test dotnet add test/test.csproj package coverlet.msbuild -v 1.2.0 dotnet sln CIDemo.sln add test/test.csproj 

xunit is a framework for testing, and coverlet.msbuild is a code coverage reporting tool.

Add a class and write a test for it.

 ```c# using web; using Xunit; namespace test { public class IdProviderTest { [Fact] public void NewIdShouldReturnUniqueValues() { var idProvider = new IdProvider(); var id1 = idProvider.NewId(); var id2 = idProvider.NewId(); Assert.NotEqual(id1, id2); } } } 

Add a command to the script section to run tests.

  - dotnet test -c Release --no-build test/test.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=opencover 

The minimum code coverage level is set using the / p flag: Threshold = TRESHOLD_LVL

Add a new section to .travis.yml

  after_script: - bash <(curl -s https://codecov.io/bash) 

The team sends test results to codecov. The documentation is here .

Log in to https://codecov.io and give it access to your repository.

The result of the codecov:

Everything, CI is configured.

The final version .travis.yml

 language: csharp dotnet: 2.1.4 sudo: false env: global: - DOTNET_CLI_TELEMETRY_OPTOUT: 1 script: - dotnet build CIDemo.sln -c Release - dotnet test -c Release --no-build test/test.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=opencover after_script: - bash <(curl -s https://codecov.io/bash) 

Analogs Travis

• Codeship (Free for OpenSource)
• Circleci (Free for 1,500 build minutes - + - 300 builds if that)
• Buddy (Free 120 builds but for OpenSource promise to increase if you write to tech support)
• AppVeyor is free for OpenSource - thanks to pankraty for the tip.

Instead of Codecov for work with tests it is possible to use https://coveralls.io/ . Also free for open source projects.

useful links

• Travis documentation
• Codecov documentation
• Coverlet documentation

If you know other alternative and free solutions for CI - write, add to the article.

Thanks to all. I hope it turned out short and to the point.
