Devops + CI/CD-part 5

This is a part of the series where about how I made the WebAPI2CLI - Execute ASP.NET Core WebAPI from Command Line

What I need for the devops:

1. Building the solution

2. Running tests

3. Deploying packages to Nuget

Being part of the Microsoft stack, it is normal that I have choose for CI / CD the Azure Devops.

You can see the AzureDevops at https://dev.azure.com/ignatandrei0674/WebAPI2CLI/_build?definitionId=7&_a=summary and how it is done by reading https://github.com/ignatandrei/WebAPI2CLI/blob/master/azure-pipelines.yml

Seeing code coverage in AzureDevops

I need not only to know that tests have runned with success, but also to see the code coverage

For this I use the .NET local tools, coverlet and report generator

dotnet coverlet bin\$(buildConfiguration)\netcoreapp3.1\CLITests.dll –target “dotnet” –targetargs “test –no-build –configuration $(buildConfiguration)” –exclude ‘[*Test*]*’ –format opencover  –output $(Build.ArtifactStagingDirectory)\testResults\coverlet.xml

dotnet reportgenerator “-reports:$(Build.ArtifactStagingDirectory)\testResults\coverlet.xml” “-targetdir:$(Build.ArtifactStagingDirectory)\testResults” “-reporttypes:Cobertura;HtmlSummary;Badges;HtmlInline_AzurePipelines”

– task: PublishTestResults@2

inputs:

testResultsFormat: ‘VSTest’

testResultsFiles: ‘**/*.trx’

searchFolder: ‘$(Build.ArtifactStagingDirectory)\trx’

displayName: publish tests

– task: PublishCodeCoverageResults@1

displayName: ‘Publish code coverage’

inputs:

codeCoverageTool: Cobertura

summaryFileLocation: ‘$(Build.ArtifactStagingDirectory)\testResults\Cobertura.xml’

reportDirectory: ‘$(Build.ArtifactStagingDirectory)\testResults’

In this way , you can see the

Modify version 

For a good CD I need also a way to modify the version automatically.

 

The .Net local Tools provides a way to install some tools on the local system to be run within dotnet.

So I install pwsh  -and run a setversion.ps1

 

$TimeNow = Get-Date

$d = $TimeNow.ToUniversalTime()

$year = $TimeNow.Year

$startOfYear = Get-Date -Year $year -Month 1 -Day 1 -Hour 0 -Minute 0 -Second 0 -Millisecond 0

$diff = NEW-TIMESPAN -Start $startOfYear -End $TimeNow

#$diff.TotalSeconds -as [int]

$assemblyVersion=$d.ToString(“1.yyyy.1MMdd.1HHmm”)

dotnet-property “**/*.csproj” AssemblyVersion:”$assemblyVersion”

dotnet dotnet-property “**/*.csproj” AssemblyVersion:”$assemblyVersion”

$version=$d.ToString(“1.0.yyyy.”) + ($diff.TotalSeconds -as [int]).ToString()

dotnet-property “**/*.csproj” Version:”$version”

dotnet dotnet-property “**/*.csproj” Version:”$version”

$releaseNotes = “BuildNumber $env:BUILD_BUILDNUMBER”

$releaseNotes += “;author $env:BUILD_SOURCEVERSIONAUTHOR”

$releaseNotes += “;message $env:BUILD_SOURCEVERSIONMESSAGE”

$releaseNotes +=”;source for this release github.com/ignatandrei/webAPI2CLI/commit/$env:BUILD_SOURCEVERSION”

$releaseNotes

dotnet-property “**/*.csproj” PackageReleaseNotes:”$releaseNotes”

dotnet dotnet-property “**/*.csproj” PackageReleaseNotes:”$releaseNotes”

I think that it is self explanatory.

Be a good nuget citizen –do not deploy every time a modification is made

For this I use devops variable :  deployNuget: ‘0’

– task: NuGetCommand@2

condition: and(succeeded(), eq(variables[‘deployNuget’], ‘1’))

inputs:

command: push

nuGetFeedType: external

packagesToPush: ‘$(Build.ArtifactStagingDirectory)/**/*.symbols.nupkg’

publishFeedCredentials: ‘nugetAndrei’

displayName: ‘dotnet nuget push’

Be a good AzureDevops citizen – do not run automation every time

I have some documentation on .md files – no need to rebuild everything when just the documentation is done

This is done in AzureDevOps by the trigger:

trigger:

branches:

include:

– master

paths:

exclude:

– docs/*

– README.md

Test your application

I also can test in AzureDevops what I have done by runnning

TestWebAPISite.exe  –CLI_ENABLED=1 –CLI_Commands=”GetMathId_Http,MathPOST”

It is just nice – maybe I can find a way to do something practical …
