How to create HTML report with details of test execution

Very often , we will be required to create a report with details of test execution , so that it can be presented to various stakeholders. Specflow provides a feature to create HTML reports. Let us look into more details about how is this done

  • Read through and understand details of reporting from specflow.
  • Ensure packages for Specflow, Nunit, Nunit console runner are already installed.
  • If you are using Nunit 3, install NUnit.Extension.NUnitV2ResultWriter package via nuget package manager. If this is not installed, we will get an error “Unknown result format: nunit2”.
  • Follow setups required for running specflow test cases from command line. Details can be found here.
  • Modify the bat file to create nunit2 reports.
PathToNunitConsolerunner\nunit3-console.exe --labels=All --out=TestResult.txt "--result=TestResult.xml;format=nunit2" PathTo\AcceptanceTests.dll
  • Add below command into Bat file. This will create HTML Report called “MyResult.html”
PathToSpecfloPackage\specflow.exe nunitexecutionreport PathTo\AcceptanceTests.csproj /out:MyResult.html
  • Final bat file will look like below.
