SpecFlow 2 Pre-release with Updated Gherkin Parser

A new SpecFlow 2 pre-release package (SpecFlow 2.1.0-preview20160412-16) is available on NuGet:

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

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+ Excel 1.4 Release Candidate

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 Release Candidate

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.

SpecFlow V2 Release

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!


Important changes in SpecFlow V2 include:

  • All components upgraded to .NET 4.5.
    Note: SpecFlow v2 will no longer work with older .NET runtimes!
  • Upgraded to the new Gherkin 3 parser
    Note: This change may mean that older feature files are no longer parsed correctly!
  • Support for parallel SpecFlow tests within the same AppDomain
  • Visual Studio integration has been separated to a separate project
  • Support for xUnit 2.0 and NUnit 3.0, including parallel test execution. The older providers have been retained and renamed (to xunit.1 and nunit.2 respectively).
  • Ability to determine the execution order of hooks (e.g. [BeforeScenario])
  • Extensible table conversions and comparisons for CreateSet, CreateInstance, CompareToSet andCompareToInstance.
  • Access the details of the currently executed step with ScenarioContext.StepContext
  • Display tags in NUnit test adapter in Visual Studio
  • Better regular expression suggestions generated for missing steps with quoted parameters
  • Steps base class provides properties for thread-safe access to feature, scenario and step contexts
  • Scenario and feature context can be injected to the binding class, avoiding static ScenarioContext.Current and FeatureContext.Current accessors
  • Better matching of column names to property names by removing characters that are invalid in property names
  • Small improvements in the DI framework
  • Easily configure SpecFlow to work with MSTest using the SpecFlow.MsTest NuGet package
  • Test execution report now includes “tags” in the NUnit report, which can be displayed using a custom XSLT
  • Removed .NET runtime version from generated file headers to avoid unwanted changes

SpecFlow+ Version 1.3 Released

Note: If you haven’t already, please read the information on upgrading to SpecFlow 2.

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.

For detailed information on upgrading to SpecFlow+ 1.3, refer to the documentation here.
