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:
x
of type Any
,
x.equals(x)
should return true
.x
and y
of type
Any
, x.equals(y)
should return true
if and only
if y.equals(x)
returns true
.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)
).
the object to compare against this object for equality.
true
if the receiver object is equivalent to the argument; false
otherwise.

The depth in the stack trace of this exception at which the line of test code that failed resides
The depth in the stack trace of this exception at which the line of test code that failed resides.
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.

Exception that indicates an action that is only allowed during a suite's test registration phase, such as registering a test to run or ignore, was attempted after registration had already closed.
In suites that register tests as functions, such as
FunSuite
andSpec
, tests are normally registered during construction. Although it is not the usual approach, tests can also be registered after construction by invoking methods that register tests on the already constructed suite so long asrun
has not been invoked on that suite. As soon asrun
is invoked for the first time, registration of tests is "closed," meaning that any further attempts to register a test will fail (and result in an instance of this exception class being thrown). This can happen, for example, if an attempt is made to nest tests, such as in aFunSuite
:This exception encapsulates information about the stack depth at which the line of code that made this attempt resides, so that information can be presented to the user that makes it quick to find the problem line of code. (In other words, the user need not scan through the stack trace to find the correct filename and line number of the offending code.)
