Registers a subject description in WordSpec
and FixtureWordSpec
Registers a subject description in WordSpec
and FixtureWordSpec
.
For example, this class enables syntax such as the following in WordSpec
and FixtureWordSpec
:
"A Stack (when empty)" should { ...
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.
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 a string representation of the object
Returns a string representation of the object.
The default representation is platform dependent.
Class that provides a role-specific type for an implicit conversion used to support the registration of subject descriptions in
WordSpec
andFixtureWordSpec
.For example, this class enables syntax such as the following in
WordSpec
andFixtureWordSpec
:This
should
method, which is provided inShouldVerb
, needs an implicit parameter of type(String, String, () => Unit) => Unit
. Because the required type has no ScalaTest-specific types in it, it is possible that another implicit parameter of that same type could be in scope, which would cause a compile failure. Requiring an implicit parameter of the more specificStringVerbBlockRegistration
, which simply extends the needed type,(String, String, () => Unit) => Unit
, avoids this potential conflict.
