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.
