  • Fixed hooks with multiple tags executing more than once #848

  • Updated Gherkin parser
  • Improved output support for the specflow.exe GenerateAll command

SpecFlow+ Excel has been updated for compatibility with SpecFlow 2. A pre-release version is now available on NuGet. This package requires an updated pre-release version of SpecFlow 2 that will automatically be installed with the SpecFlow+ Excel package. The new SpecFlow 2 package includes an updated Gherkin parser required by the Excel plugin. SpecFlow+ Runner has also been updated to this new version.

Note: This is a pre-release version; the package will only show up in the NuGet package manager in Visual Studio if you chose to “Include prereleases”.

SpecFlow+ Runner 1.4 has been released on NuGet.org. This is a pre-release version, so the package will only show up in Visual Studio if you have chosen to display pre-releases.

This release introduces SharedAppDomain support for test thread isolation in order to use the parallelization features introduced with SpecFlow 2.

You can also read more about parallelisation in SpecFlow+ on developer Andreas Willich’s blog.

Before installing the new version, please read the information on updating. The installation procedure is also covered there. Note that SpecFlow 2 requires .NET 4.5 or higher!

  • Extensible table conversions and comparisons for CreateSet, CreateInstance, CompareToSet andCompareToInstance.
  • Access the details of the currently executed step with ScenarioContext.StepContext

SpecFlow+ 1.3 has been released. This new version supports SpecFlow 2. SpecFlow+ 1.3 also uses Razor 3.6.1 (as opposed to Razor 2.1.0). This means you may need to update your report templates to refect the changes in the Razor syntax in 3.6.1.
