FixtureAsyncFlatSpec

abstract class FixtureAsyncFlatSpec extends FixtureAsyncFlatSpecLike

A sister class to org.scalatest.flatspec.AsyncFlatSpec that can pass a fixture object into its tests.

Recommended Usage: Use class FixtureAsyncFlatSpec in situations for which AsyncFlatSpec would be a good choice, when all or most tests need the same fixture objects that must be cleaned up afterwards. Note: FixtureAsyncFlatSpec is intended for use in special situations, with class AsyncFlatSpec used for general needs. For more insight into where FixtureAsyncFlatSpec fits in the big picture, see the withFixture(OneArgAsyncTest) subsection of the Shared fixtures section in the documentation for class AsyncFlatSpec.

Class FixtureAsyncFlatSpec behaves similarly to class org.scalatest.flatspec.AsyncFlatSpec, except that tests may have a fixture parameter. The type of the fixture parameter is defined by the abstract FixtureParam type, which is a member of this class. This class also contains an abstract withFixture method. This withFixture method takes a OneArgAsyncTest, which is a nested trait defined as a member of this class. OneArgAsyncTest has an apply method that takes a FixtureParam. This apply method is responsible for running a test. This class's runTest method delegates the actual running of each test to withFixture(OneArgAsyncTest), passing in the test code to run via the OneArgAsyncTest argument. The withFixture(OneArgAsyncTest) method (abstract in this class) is responsible for creating the fixture argument and passing it to the test function.

Subclasses of this class must, therefore, do three things differently from a plain old org.scalatest.flatspec.AsyncFlatSpec:

  • define the type of the fixture parameter by specifying type FixtureParam
  • define the withFixture(OneArgAsyncTest) method
  • write tests that take a fixture parameter
  • (You can also define tests that don't take a fixture parameter.)

If the fixture you want to pass into your tests consists of multiple objects, you will need to combine them into one object to use this class. One good approach to passing multiple fixture objects is to encapsulate them in a case class. Here's an example:

case class FixtureParam(file: File, writer: FileWriter)

To enable the stacking of traits that define withFixture(NoArgAsyncTest), it is a good idea to let withFixture(NoArgAsyncTest) invoke the test function instead of invoking the test function directly. To do so, you'll need to convert the OneArgAsyncTest to a NoArgAsyncTest. You can do that by passing the fixture object to the toNoArgAsyncTest method of OneArgAsyncTest. In other words, instead of writing “test(theFixture)”, you'd delegate responsibility for invoking the test function to the withFixture(NoArgAsyncTest) method of the same instance by writing:

withFixture(test.toNoArgAsyncTest(theFixture))

Here's a complete example:

package org.scalatest.examples.asyncflatspec.oneargasynctest

import org.scalatest._
import scala.concurrent.Future
import scala.concurrent.ExecutionContext

// Defining actor messages
sealed abstract class StringOp
case object Clear extends StringOp
case class Append(value: String) extends StringOp
case object GetValue

class StringActor { // Simulating an actor
  private final val sb = new StringBuilder
  def !(op: StringOp): Unit =
    synchronized {
      op match {
        case Append(value) => sb.append(value)
        case Clear => sb.clear()
      }
    }
  def ?(get: GetValue.type)(implicit c: ExecutionContext): Future[String] =
    Future {
      synchronized { sb.toString }
    }
}

class ExampleSpec extends flatspec.FixtureAsyncFlatSpec {

  type FixtureParam = StringActor

  def withFixture(test: OneArgAsyncTest): FutureOutcome = {

    val actor = new StringActor
    complete {
      actor ! Append("ScalaTest is ") // set up the fixture
      withFixture(test.toNoArgAsyncTest(actor))
    } lastly {
      actor ! Clear // ensure the fixture will be cleaned up
    }
  }

  "Testing" should "be easy" in { actor =>
    actor ! Append("easy!")
    val futureString = actor ? GetValue
    futureString map { s =>
      assert(s == "ScalaTest is easy!")
    }
  }

  it should "be fun" in { actor =>
    actor ! Append("fun!")
    val futureString = actor ? GetValue
    futureString map { s =>
      assert(s == "ScalaTest is fun!")
    }
  }

}

If a test fails, the future returned by the OneArgAsyncTest function will result in an org.scalatest.Failed wrapping the exception describing the failure. To ensure clean up happens even if a test fails, you should invoke the test function and do the cleanup using complete-lastly, as shown in the previous example. The complete-lastly syntax, defined in CompleteLastly, which is extended by AsyncTestSuite, ensures the second, cleanup block of code is executed, whether the the first block throws an exception or returns a future. If it returns a future, the cleanup will be executed when the future completes.

Sharing fixtures across classes

If multiple test classes need the same fixture, you can define the FixtureParam and withFixture(OneArgAsyncTest) implementations in a trait, then mix that trait into the test classes that need it. For example, if your application requires a database and your integration tests use that database, you will likely have many test classes that need a database fixture. You can create a "database fixture" trait that creates a database with a unique name, passes the connector into the test, then removes the database once the test completes. This is shown in the following example:

package org.scalatest.examples.fixture.asyncflatspec.sharing

import java.util.concurrent.ConcurrentHashMap
import org.scalatest._
import DbServer._
import java.util.UUID.randomUUID
import scala.concurrent.Future

object DbServer { // Simulating a database server
  type Db = StringBuffer
  private val databases = new ConcurrentHashMap[String, Db]
  def createDb(name: String): Db = {
    val db = new StringBuffer
    databases.put(name, db)
    db
  }
  def removeDb(name: String) {
    databases.remove(name)
  }
}

trait DbFixture { this: FixtureAsyncTestSuite =>

  type FixtureParam = Db

  // Allow clients to populate the database after
  // it is created
  def populateDb(db: Db) {}

  def withFixture(test: OneArgAsyncTest): FutureOutcome = {
    val dbName = randomUUID.toString
    val db = createDb(dbName) // create the fixture
    complete {
      populateDb(db) // setup the fixture
      withFixture(test.toNoArgAsyncTest(db)) // "loan" the fixture to the test
    } lastly {
      removeDb(dbName) // ensure the fixture will be cleaned up
    }
  }
}

class ExampleSpec extends flatspec.FixtureAsyncFlatSpec with DbFixture {

  override def populateDb(db: Db) { // setup the fixture
    db.append("ScalaTest is ")
  }

  "Testing" should "should be easy" in { db =>
    Future {
      db.append("easy!")
      assert(db.toString === "ScalaTest is easy!")
    }
  }

  it should "be fun" in { db =>
    Future {
      db.append("fun!")
      assert(db.toString === "ScalaTest is fun!")
    }
  }

  // This test doesn't need a Db
  "Test code" should "be clear" in { () =>
    Future {
      val buf = new StringBuffer
      buf.append("ScalaTest code is ")
      buf.append("clear!")
      assert(buf.toString === "ScalaTest code is clear!")
    }
  }
}

Often when you create fixtures in a trait like DbFixture, you'll still need to enable individual test classes to "setup" a newly created fixture before it gets passed into the tests. A good way to accomplish this is to pass the newly created fixture into a setup method, like populateDb in the previous example, before passing it to the test function. Classes that need to perform such setup can override the method, as does ExampleSuite.

If a test doesn't need the fixture, you can indicate that by providing a no-arg instead of a one-arg function, as is done in the third test in the previous example, “test code should be clear”. In other words, instead of starting your function literal with something like “db =>”, you'd start it with “() =>”. For such tests, runTest will not invoke withFixture(OneArgAsyncTest). It will instead directly invoke withFixture(NoArgAsyncTest).

Both examples shown above demonstrate the technique of giving each test its own "fixture sandbox" to play in. When your fixtures involve external side-effects, like creating files or databases, it is a good idea to give each file or database a unique name as is done in these examples. This keeps tests completely isolated, allowing you to run them in parallel if desired. You could mix ParallelTestExecution into either of these ExampleSuite classes, and the tests would run in parallel just fine.

A org.scalatest.flatspec.FixtureAsyncFlatSpec needs two in methods, one that takes a no-arg test function and another that takes a one-arg test function (a test that takes a FixtureParam as its parameter). By constrast, a AsyncFlatSpec needs only one in method that takes a by-name parameter. As a result, AsyncFlatSpec and org.scalatest.flatspec.FixtureAsyncFlatSpec each provide an implicit conversion from ResultOfStringPassedToVerb to a type that provides the appropriate in methods.

    Returns an Alerter that during test execution will forward strings (and other objects) passed to its apply method to the current reporter. If invoked in a constructor, it will register the passed string for forwarding later during test execution. If invoked while this FixtureAsyncFlatSpec is being executed, such as from inside a test function, it will forward the information to the current reporter immediately. If invoked at any other time, it will print to the standard output. This method can be called safely by any thread.

    Run a test.

    Run a test. This trait's implementation runs the test registered with the name specified by testName. Each test's name is a concatenation of the text of all describers surrounding a test, from outside in, and the test's spec text, with one space placed between each item. (See the documenation for testNames for an example.)

    testName

    the name of one test to execute.

    Run zero to many of this FixtureAsyncFlatSpec's tests.

    Run zero to many of this FixtureAsyncFlatSpec's tests.

    This method takes a testName parameter that optionally specifies a test to invoke. If testName is Some, this trait's implementation of this method invokes runTest on this object with passed args.

    This method takes an args that contains a Set of tag names that should be included (tagsToInclude), and a Set that should be excluded (tagsToExclude), when deciding which of this Suite's tests to execute. If tagsToInclude is empty, all tests will be executed except those those belonging to tags listed in the tagsToExclude Set. If tagsToInclude is non-empty, only tests belonging to tags mentioned in tagsToInclude, and not mentioned in tagsToExclude will be executed. However, if testName is Some, tagsToInclude and tagsToExclude are essentially ignored. Only if testName is None will tagsToInclude and tagsToExclude be consulted to determine which of the tests named in the testNames Set should be run. For more information on trait tags, see the main documentation for this trait.

    If testName is None, this trait's implementation of this method invokes testNames on this Suite to get a Set of names of tests to potentially execute. (A testNames value of None essentially acts as a wildcard that means all tests in this Suite that are selected by tagsToInclude and tagsToExclude should be executed.) For each test in the testName Set, in the order they appear in the iterator obtained by invoking the elements method on the Set, this trait's implementation of this method checks whether the test should be run based on the tagsToInclude and tagsToExclude Sets. If so, this implementation invokes runTest with the passed args.

    testName

    an optional name of one test to execute. If None, all relevant tests should be executed. I.e., None acts like a wildcard that means execute all relevant tests in this FixtureAsyncFlatSpecLike.

    args

    the Args for this run

    returns

    a Status object that indicates when all tests started by this method have completed, and whether or not a failure occurred.
