JUnitTestFailedError

class JUnitTestFailedError extends AssertionFailedError with StackDepth with ModifiableMessage[JUnitTestFailedError]

Exception that indicates a test failed.

The purpose of this exception is to encapsulate the same stack depth information provided byTestFailedException, which is used when running with ScalaTest, but be reported as a failure not an error when running with JUnit. The stack depth information indicates which line of test code failed, so that when running with ScalaTest information can be presented to the user that makes it quick to find the failing line of test code. (In other words, when running with ScalaTest the user need not scan through the stack trace to find the correct filename and line number of the failing test.)

JUnit distinguishes between failures and errors. If a test fails because of a failed assertion, that is considered a failure in JUnit. If a test fails for any other reason, either the test code or the application being tested threw an unexpected exception, that is considered an error in JUnit. This class differs fromTestFailedException in that it extendsjunit.framework.AssertionFailedError. Instances of this class are thrown by the assertions provided by AssertionsForJUnit, and matcher expressions provided by ShouldMatchersForJUnit, andMustMatchersForJUnit.

The way JUnit 3 (JUnit 3.8 and earlier releases) decided whether an exception represented a failure or error is that only thrown junit.framework.AssertionFailedErrors were considered failures. Any other exception type was considered an error. The exception type thrown by the JUnit 3 assertion methods declared in junit.framework.Assert (such as assertEquals, assertTrue, and fail) was, therefore, AssertionFailedError. In JUnit 4, AssertionFailedErrorwas made to extend java.lang.AssertionError, and the distinction between failures and errors was essentially dropped. However, some tools that integrate with JUnit carry on this distinction, so even if you are using JUnit 4 you may want to use the "ForJUnit" of ScalaTest assertions and matchers.

  8. 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.

  12. 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.

  13. def equals (other: Any) : Boolean

    Indicates whether this object is equal to the passed object.

    Indicates whether this object is equal to the passed object. If the passed object is a JUnitTestFailedError, equality requires equal message,cause, and failedCodeStackDepth fields, as well as equal return values of getStackTrace.@return true if the receiver object is equivalent to the argument; false otherwise. */
