Usage
To learn how to use ReportGenerator have a look at the:
YAML example
- task: reportgenerator@5
displayName: ReportGenerator
inputs:
reports: 'coverage.xml' # REQUIRED # The coverage reports that should be parsed (separated by semicolon). Globbing is supported.
targetdir: 'coveragereport' # REQUIRED # The directory where the generated report should be saved.
reporttypes: 'HtmlInline_AzurePipelines;Cobertura' # The output formats and scope (separated by semicolon) Values: Badges, Clover, Cobertura, OpenCover, CsvSummary, Html, Html_Dark, Html_Light, Html_BlueRed, HtmlChart, HtmlInline, HtmlInline_AzurePipelines, HtmlInline_AzurePipelines_Dark, HtmlInline_AzurePipelines_Light, HtmlSummary, Html_BlueRed_Summary, JsonSummary, CodeClimate, Latex, LatexSummary, lcov, MarkdownSummary, MarkdownAssembliesSummary, MarkdownSummaryGithub, MarkdownDeltaSummary, MHtml, SvgChart, SonarQube, TeamCitySummary, TextSummary, TextDeltaSummary, Xml, XmlSummary
sourcedirs: '' # Optional directories which contain the corresponding source code (separated by semicolon). The source directories are used if coverage report contains classes without path information.
historydir: '' # Optional directory for storing persistent coverage information. Can be used in future reports to show coverage evolution.
plugins: '' # Optional plugin files for custom reports or custom history storage (separated by semicolon).
assemblyfilters: '+*' # Optional list of assemblies that should be included or excluded in the report. Exclusion filters take precedence over inclusion filters. Wildcards are allowed.
classfilters: '+*' # Optional list of classes that should be included or excluded in the report. Exclusion filters take precedence over inclusion filters. Wildcards are allowed.
filefilters: '+*' # Optional list of files that should be included or excluded in the report. Exclusion filters take precedence over inclusion filters. Wildcards are allowed.
riskhotspotassemblyfilters: '+*' # Optional list of assemblies that should be included or excluded in the risk hotspots. Exclusion filters take precedence over inclusion filters. Wildcards are allowed.
riskhotspotclassfilters: '+*' # Optional list of classes that should be included or excluded in the risk hotspots. Exclusion filters take precedence over inclusion filters. Wildcards are allowed.
verbosity: 'Info' # The verbosity level of the log messages. Values: Verbose, Info, Warning, Error, Off
title: '' # Optional title.
tag: '$(build.buildnumber)_#$(build.buildid)' # Optional tag or build version.
publishCodeCoverageResults: false # Directly publish report in 'Code Coverage' tab. Makes the 'PublishCodeCoverageResults' task obsolete.
license: '' # Optional license for PRO version. Get your license here: https://reportgenerator.io/pro
customSettings: '' # Optional custom settings (separated by semicolon). See: https://github.com/danielpalme/ReportGenerator/wiki/Settings.
Attention
The PublishCodeCoverageResults@1 task from Microsoft regenerates the report with different settings and based on the supplied Coberatura file (see announcement). Moreover it does not necessarily use the latest version of ReportGenerator.
To disable the regeneration of the report, you can use the following environment variable in your build:
disable.coverage.autogenerate: 'true' # Global environment variable
- task: PublishCodeCoverageResults@1
displayName: 'Publish code coverage results'
inputs:
codeCoverageTool: Cobertura
summaryFileLocation: '$(Build.SourcesDirectory)/coveragereport/Cobertura.xml'
reportDirectory: '$(Build.SourcesDirectory)/coveragereport'
env:
DISABLE_COVERAGE_AUTOGENERATE: 'true' # Local environment variable
The PublishCodeCoverageResults@1 will get deprecated.
Microsoft recommends to use the PublishCodeCoverageResults@2 instead.
The new version has several disadvantages regarding the report in the Code Coverage tab within Azure DevOps
- No branch and method coverage
- No details page for each class
Recommendation:
Use the setting publishCodeCoverageResults: true of the ReportGenerator task. This way you don't have to use the PublishCodeCoverageResults@1 or PublishCodeCoverageResults@2 task at all.
- task: reportgenerator@5
displayName: ReportGenerator
inputs:
reports: 'coverage.xml'
targetdir: 'coveragereport'
publishCodeCoverageResults: true
If you want to use the PublishCodeCoverageResults@2 task you could additionally create an artifact containing the full coverage report generated by ReportGenerator. You can download the artifact and get full report with all features:
- publish: $(Build.SourcesDirectory)/coveragereport
artifact: CoverageReports
