Exception that indicates a test failed.
The purpose of this exception is to encapsulate the same stack depth information provided by
TestFailedException, 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 from
TestFailedException in that it extends
junit.framework.AssertionFailedError. Instances of this class are thrown by the
assertions provided by AssertionsForJUnit, and matcher
expressions provided by ShouldMatchersForJUnit, and
MustMatchersForJUnit.
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, AssertionFailedError
was 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.

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression
1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression
List(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.

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).
