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 not. In the latter example, because the type argument is erased as

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
).

However, it is required that if two objects are equal (o1.equals(o2)

This trait's implementation of runTests
invokes this method to create
a new instance of this Suite
for each test. This trait's implementation
of this method uses reflection to call this.getClass.newInstance
. This
approach will succeed only if this Suite
's class has a public, no-arg
constructor. In most cases this is likely to be true, because to be instantiated
by ScalaTest's Runner
a Suite
needs a public, no-arg
constructor. However, this will not be true of any Suite
defined as
an inner class of another class or trait, because every constructor of an inner
class type takes a reference to the enclosing instance. In such cases, and in
cases where a Suite
class is explicitly defined without a public,
no-arg constructor, you will need to override this method to construct a new
instance of the Suite
in some other way.
Here's an example of how you could override newInstance
to construct
a new instance of an inner class:
import org.scalatest.Suiteclass Outer { class InnerSuite extends Suite with OneInstancePerTest { def testOne() {} def testTwo() {} override def newInstance = new InnerSuite } }

Trait that causes that the tests of any suite it is mixed into to be run in parallel if a
Distributor
is passed torunTests
.ScalaTest's normal approach for running suites of tests in parallel is to run different suites in parallel, but the tests of any one suite sequentially. This approach should provide sufficient distribution of the work load in most cases, but some suites may encapsulate multiple long-running tests. Such suites may dominate the execution time of the run. If so, mixing in this trait into just those suites will allow their long-running tests to run in parallel with each other, thereby helping to reduce the total time required to run an entire run.
Because this trait extends
OneInstancePerTest
, each test will be run its own instance of the suite's class. This trait overrides therunTests
method. If noDistributor
is passed torunTests
, this trait's implementation simply invokes its supertraitOneInstancePerTest
's implementation ofrunTests
, which will run each test in its own instance sequentially. If aDistributor
is passed, however, this traits' implementation ofrunTests
will, for each test, wrap a new instance of the suite in a special wrapper suite that will invoke just that one test, and passes the wrapper suites to theDistributor
. The thread or entity that takes a wrapper suite from theDistributor
will invokerun
on the wrapper suite, which will run just one test. In this way, different tests of a suite that mixes inParallelTestExecution
will run in parallel.
