BeforeAndAfterAll

trait BeforeAndAfterAll extends AbstractSuite

Trait that can be mixed into suites that need methods invoked before and after executing the suite. This trait allows code to be executed before and/or after all the tests and nested suites of a suite are run. This trait overrides run (the main run method that takes seven parameters, an optional test name, reporter, stopper, filter, configMap, optional distributor, and tracker) and calls the beforeAll method, then calls super.run. After the super.run invocation completes, whether it returns normally or completes abruptly with an exception, this trait's run method will invoke afterAll.

Trait BeforeAndAfterAll defines two overloaded variants each of beforeAll and afterAll, one that takes a configMap and another that takes no arguments. This traits implemention of the variant that takes the configMap simply invokes the variant that takes no parameters, which does nothing. Thus you can override whichever variant you want. If you need something from the configMap before all tests and nested suites are run, override beforeAll(Map[String, Any]). Otherwise, override beforeAll().

For example, the following MasterSuite mixes in BeforeAndAfterAll and in beforeAll, creates and writes to a temp file, taking the name of the temp file from the configMap. This same configMap is then passed to the run methods of the nested suites, OneSuite, TwoSuite, RedSuite, and BlueSuite, so those suites can access the filename and, therefore, the file's contents. After all of the nested suites have executed, afterAll is invoked, which again grabs the file name from the configMap and deletes the file:

import org.scalatest.SuperSuite
import org.scalatest.BeforeAndAfterAll
import java.io.FileReader
import java.io.FileWriter
import java.io.File

class MasterSuite extends Suite with BeforeAndAfterAll {

  private val FileNameKeyInGoodies = "tempFileName"

  // Set up the temp file needed by the test, taking
  // a file name from the configMap
  override def beforeAll(configMap: Map[String, Any]) {

    require(
      configMap.isDefinedAt(FileNameKeyInGoodies),
      "must place a temp file name in the configMap under the key: " + FileNameKeyInGoodies
    )

    val fileName = configMap(tempFileName)

    val writer = new FileWriter(fileName)
    try {
      writer.write("Hello, suite of tests!")
    }
    finally {
      writer.close()
    }
  }

  override def nestedSuites =
    List(new OneSuite, new TwoSuite, new RedSuite, new BlueSuite)

  // Delete the temp file
  override def afterAll(configMap: Map[String, Any]) {
    // No need to require that configMap contains the key again because it won't get
    // here if it didn't contain the key in beforeAll
    val fileName = configMap(tempFileName))
    val file = new File(fileName)
    file.delete()
  }
}

Because the BeforeAndAfterAll trait invokes super.run to run the suite, you may need to mix this trait in last to get the desired behavior. For example, this won't work, because BeforeAndAfterAll is "super" to FunSuite:

class MySuite extends BeforeAndAfterAll with FunSuite

You'd need to turn it around, so that FunSuite is "super" to BeforeAndAfterAll, like this:

class MySuite extends FunSuite with BeforeAndAfterAll

Note: This trait does not currently ensure that the code in afterAll is executed after all the tests and nested suites are executed if a Distributor is passed. The plan is to do that eventually, but in the meantime, be aware that afterAll is guaranteed to be run after all the tests and nested suites only when they are run sequentially.

  8. def withFixture (test: NoArgTest): Unit

    Runs the passed test function with a fixture established by this method.

    Runs the passed test function with a fixture established by this method.

    This method should set up the fixture needed by the tests of the current suite, invoke the test function, and if needed, perform any clean up needed after the test completes. Because the NoArgTest function passed to this method takes no parameters, preparing the fixture will require side effects, such as reassigning instance vars in this Suite or initializing a globally accessible external database. If you want to avoid reassigning instance vars you can use FixtureSuite.

    test

    the no-arg test function to run with a fixture

    Execute a suite surrounded by calls to beforeAll and afterAll.

    Execute a suite surrounded by calls to beforeAll and afterAll.

    This trait's implementation of this method ("this method") invokes beforeAll(Map[String, Any]) before executing any tests or nested suites and afterAll(Map[String, Any]) after executing all tests and nested suites. It runs the suite by invoking super.run, passing along the seven parameters passed to it.

    If any invocation of beforeAll completes abruptly with an exception, this method will complete abruptly with the same exception. If any call to super.run completes abruptly with an exception, this method will complete abruptly with the same exception, however, before doing so, it will invoke afterAll. If <cod>afterAll also completes abruptly with an exception, this method will nevertheless complete abruptly with the exception previously thrown by super.run. If super.run returns normally, but afterAll completes abruptly with an exception, this method will complete abruptly with the same exception.

    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 Suite.

    stopper

    the Stopper that will be consulted to determine whether to stop execution early.
