Cucumber Plugin

Note

The plugin has moved and is now available within the sbt github.

This copy will be removed on next release.

The Cucumber plugin provides a new sbt command, allowing you to run just your Cucumber tests using sbt cucumber. You need to add the following to your plugins.sbt file.

Dependency Information

 addSbtPlugin("com.waioeka.sbt" % "cucumber-plugin" % "0.1.7")

Note, the latest version of the plugin is built using SBT 1.0.2.

Cucumber Plugin Example

The project cucumber-plugin-example highlights how to use the plugin. You will need to ensure that your build.sbt file defines both the dependencies and the 'glue' setting (i.e. where to find the step definitions).

    name := "cucumber-test"
 
    organization := "com.waioeka.sbt"
 
    version := "0.1.0"
 
    libraryDependencies ++= Seq (
    "io.cucumber" % "cucumber-core" % "2.0.1" % "test",
    "io.cucumber" %% "cucumber-scala" % "2.0.1" % "test",
    "io.cucumber" % "cucumber-jvm" % "2.0.1" % "test",
    "io.cucumber" % "cucumber-junit" % "2.0.1" % "test",
    "org.scalatest" %% "scalatest" % "2.2.5" % "test")
 
    enablePlugins(CucumberPlugin)
 
    CucumberPlugin.glue := "com/waioeka/sbt/"

    // Any environment properties you want to override/set.
    CucumberPlugin.envProperties := Map("K"->"2049")

Remember to set the CucumberPlugin.glue parameter to the sub directory in test that contains your Scala step definitions. In your resources directory, put in your feature files.

    @my-tag
    Feature: Multiplication
      In order to avoid making mistakes
      As a dummy
      I want to multiply numbers
 
    Scenario: Multiply two variables
    Given a variable x with value 2
    And a variable y with value 3
    When I multiply x * y
    Then I get 6

If you need to generate the stubs, just run sbt cucumber and you will get an error complaining about missing stubs. You can copy and paste the stub functions into your step implementation.

You can now put in your stub implementation:

    package com.waioeka.sbt
 
    import cucumber.api.scala.{ScalaDsl, EN}
    import org.scalatest.Matchers
 
    /** AddAndMultiplySteps*/
    class MultiplicationSteps extends ScalaDsl with EN with Matchers {
      var x : Int = 0
      var y : Int = 0
      var z : Int = 0
 
      Given("""^a variable x with value (\d+)$""") { (arg0: Int) => x = arg0 }
 
      Given("""^a variable y with value (\d+)$""") { (arg0: Int) => y = arg0 }
 
      When("""^I multiply x \* y$""") { () => z = x * y }
 
      Then("""^I get (\d+)$""") { (arg0: Int) => z should be (arg0) }
    }

To run the tests in standalone mode:

sbt compile
sbt cucumber

You should see some output as follows:

Cucumber Plugin Arguments

Cucumber arguments may be supplied. For example, sbt "cucumber --tags ~@my-tag" will filter tagged feature files.

Properties

In your build.sbt file you can now specify environment variables as follows:

  CucumberPlugin.envProperties := Map("K"->"2049")

The setting expects a type of Map[String,String].
