PrivateMethodTester

object PrivateMethodTester extends PrivateMethodTester

Companion object that facilitates the importing of PrivateMethodTester members as an alternative to mixing it in. One use case is to import PrivateMethodTester members so you can use them in the Scala interpreter:

$scala -classpath scalatest.jar
Welcome to Scala version 2.7.5.final (Java HotSpot(TM) Client VM, Java 1.5.0_16).
Type in expressions to have them evaluated.
Type :help for more information.

scala> import org.scalatest.PrivateMethodTester._ import org.scalatest.PrivateMethodTester._

scala> class Example { | private def addSesame(prefix: String) = prefix + " sesame" | } defined class Example

scala> val example = new Example example: Example = Example@d8b6fe

scala> val addSesame = PrivateMethod[String]('addSesame) addSesame: org.scalatest.PrivateMethodTester.PrivateMethod[String] = org.scalatest.PrivateMethodTester$PrivateMethod@5cdf95

scala> example invokePrivate addSesame("open") res0: String = open sesame

Inherits

  1. PrivateMethodTester
  2. AnyRef
  3. Any

Type Members

  1. class Invocation[T] extends AnyRef

    Class whose instances represent an invocation of a private method

  2. class Invoker extends AnyRef

    Class used via an implicit conversion to enable private methods to be tested

  3. class PrivateMethod[T] extends AnyRef

    Represent a private method, whose apply method returns an Invocation object that records the name of the private method to invoke, and any arguments to pass to it when invoked

Value Members

  1. object PrivateMethod extends AnyRef

    Contains a factory method for instantiating PrivateMethod objects

  2. def anyRefToInvoker(target: AnyRef): Invoker

    Implicit conversion from AnyRef to Invoker, used to enable assertions testing of private methods

    Implicit conversion from AnyRef to Invoker, used to enable assertions testing of private methods.

    target

    the target object on which to invoke a private method.

  3. 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 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 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.

  4. 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.

  5. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.
