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 thebeforeAll method, then calls super.run. After the super.runinvocation completes, whether it returns normally or completes abruptly with an exception, this trait's run method will invoke afterAll.

Trait BeforeAndAfterEach defines two overloaded variants each of beforeAlland afterAll, one which takes a configMap and another that takes no arguments. This traits implemention of the variant that takes the configMapsimply 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 runmethods 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.BeforeAndAfterEach
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.

  10. def asInstanceOf[T0]: T0

    This method is used to cast the receiver object to be of type T0.

    This method is used to cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expressionList(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

    returns

    the receiver object.

  14. def eq(arg0: AnyRef): Boolean

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on non-null instances of AnyRef: * It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true. * It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and only if y.eq(x) returns true. * It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.

    Additionally, the eq method has three other properties. * It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false. * For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false. * null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    arg0

    the object to compare against this object for reference equality.

    returns

    true if the argument is a reference to the receiver object; false otherwise.

    definition classes: AnyRef
  15. def equals(arg0: Any): Boolean

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation]: * It is reflexive: for any instance x of type Any, x.equals(x) should return true. * It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true. * It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same scala.Int (o1.hashCode.equals(o2.hashCode)).

    arg0

    the object to compare against this object for equality.

    returns

    true if the receiver object is equivalent to the argument; false otherwise.

  19. def hashCode(): Int

    Returns a hash code value for the object.

    Returns a hash code value for the object.

    The default hashing algorithm is platform dependent.

    Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

    returns

    the hash code value for the object.

  20. def isInstanceOf[T0]: Boolean

    This method is used to test whether the dynamic type of the receiver object is T0.

    Note that the test result of the test is modulo Scala's erasure semantics. Therefore the expression1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

    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 tosuper.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.
