-
The runner (0.2.0) now supports running test suites in parallel.
-
The existing method of running everything serially and producing a consolidated report is still supported.
-
A new method of defining suites that can run in parallel is introduced.
Described below, project examples of both approaches are here.
-
-
The plugin has moved and is now available within the sbt github.
This project contains a Cucumber test framework for sbt. There is also a plugin that provides a new sbt command.
-
Cucumber Test Framework An sbt test framework, the runner, runs Cucumber tests as part of a unit test run (i.e.
sbt test). -
An SBT plugin that provides a new command
sbt cucumber. It allows you to run Cucumber tests independently of unit tests.
Unless you have a specific requirement to run Cucumber tests outside of unit test framework, use the test framework rather than the plugin.
The plugin can be used if you want a separate command to run Cucumber tests and have your normal test framework ignore Cucumber tests. If you want to use the plugin, there is more information here.
The Cucumber test framework does not depend on the plugin.

You can run tests two ways:
-
Run tests in parallel. Each test suite must mixin
CucumberTestSuiteand overload two methods, that tell the suite which are the corresponding features to run and which sub-directory of the plugin output to put the results. -
Sequentially, this runs all Cucumber tests serially and produces a consolidated output, i.e. a single html or json (choose the plugin(s) in your build.sbt file.)
Define a suite that supports a number of features, for example,
class AddAndMultiplySteps extends ScalaDsl with EN with Matchers with CucumberTestSuite {
override def features = List("Multiplication.feature","Addition.feature")
override def path = "addAndMult" // this is the output path, appended to plugin path.
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$""") { () =>
z = x * y
}
When("""^I add x \+ y$"""){ () =>
z = x + y
}
Then("""^I get (\d+)$""") { (arg0: Int) =>
z should be (arg0)
}
}In your build.sbt switch on the parallel output:
val framework = new TestFramework("com.waioeka.sbt.runner.CucumberFramework")
testFrameworks += framework
// Configure the arguments.
testOptions in Test += Tests.Argument(framework,"--glue","")
testOptions in Test += Tests.Argument(framework,"--plugin","html:/tmp/html")
testOptions in Test += Tests.Argument(framework,"--plugin","json:/tmp/json")
/** can remove pretty printing if running in parallel. */
parallelExecution in Test := trueAt present, the output for each suite will be a sub-directory of the plugin output.
In your test project define an empty class that inherits from Cucumber Spec
class Spec extends CucumberSpecAdd the following properties to build.sbt:
val framework = new TestFramework("com.waioeka.sbt.runner.CucumberFramework")
testFrameworks += framework
// Configure the arguments.
testOptions in Test += Tests.Argument(framework,"--glue","")
testOptions in Test += Tests.Argument(framework,"--plugin","pretty")
testOptions in Test += Tests.Argument(framework,"--plugin","html:/tmp/html")
testOptions in Test += Tests.Argument(framework,"--plugin","json:/tmp/json")
parallelExecution in Test := false The framework will expect feature files in the test/resources directory. If your feature files are stored elsewhere, add that location to the 'unmanagedClasspath', e.g.
unmanagedClasspath in Test += baseDirectory.value / "src/test/features"The project example illustrates how to setup and use the runner. To integrate BDD testing into your unit test framework.
As shown below, using the runner and plugin, you can now run sbt test.

As a dummy
I want to multiply numbers
Scenario: Multiply two variables # Multiplication.feature:7
Given a variable x with value 2 # MultiplicationSteps.scala:44
And a variable y with value 3 # MultiplicationSteps.scala:48
When I multiply x * y # MultiplicationSteps.scala:52
Then I get 6 # MultiplicationSteps.scala:56
