Because trait Suite mixes in Assertions, this implicit conversion will always be
available by default in ScalaTest Suites. This is the only implicit conversion that is in scope by default in every
ScalaTest Suite. Other implicit conversions offered by ScalaTest, such as those that support the matchers DSL
or invokePrivate, must be explicitly invited into your test code, either by mixing in a trait or importing the
members of its companion object. The reason ScalaTest requires you to invite in implicit conversions (with the exception of the
implicit conversion for === operator) is because if one of ScalaTest's implicit conversions clashes with an
implicit conversion used in the code you are trying to test, your program won't compile. Thus there is a chance that if you
are ever trying to use a library or test some code that also offers an implicit conversion involving a === operator,
you could run into the problem of a compiler error due to an ambiguous implicit conversion. If that happens, you can turn off
the implicit conversion offered by this convertToEqualizer method simply by overriding the method in your
Suite subclass, but not marking it as implicit:
// In your Suite subclass override def convertToEqualizer(left: Any) = new Equalizer(left)

Describe a “subject” being specified and tested by the passed function value.
Describe a “subject” being specified and tested by the passed function value. The

Executes one or more tests in this Suite, printing results to the standard output.
This method invokes run on itself, passing in values that can be configured via the parameters to this
method, all of which have default values. This behavior is convenient when working with ScalaTest in the Scala interpreter.
Here's a summary of this method's parameters and how you can use them:
The testName parameter
If you leave testName at its default value (of null), this method will pass None to
the testName parameter of run, and as a result all the tests in this suite will be executed. If you
specify a testName, this method will pass Some(testName) to run, and only that test
will be run. Thus to run all tests in a suite from the Scala interpreter, you can write:
scala> (new ExampleSuite).execute()
To run just the test named "my favorite test" in a suite from the Scala interpreter, you would write:
scala> (new ExampleSuite).execute("my favorite test")
Or:
scala> (new ExampleSuite).execute(testName = "my favorite test")
The configMap parameter
If you provide a value for the configMap parameter, this method will pass it to run. If not, the default value
of an empty Map will be passed. For more information on how to use a config map to configure your test suites, see
the config map section in the main documentation for this trait. Here's an example in which you configure
a run with the name of an input file:
scala> (new ExampleSuite).execute(configMap = Map("inputFileName" -> "in.txt")
The color parameter
If you leave the color parameter unspecified, this method will configure the reporter it passes to run to print
to the standard output in color (via ansi escape characters). If you don't want color output, specify false for color, like this:
scala> (new ExampleSuite).execute(color = false)
The durations parameter
If you leave the durations parameter unspecified, this method will configure the reporter it passes to run to
not print durations for tests and suites to the standard output. If you want durations printed, specify true for durations,
like this:
scala> (new ExampleSuite).execute(durations = true)
The shortstacks and fullstacks parameters
If you leave both the shortstacks and fullstacks parameters unspecified, this method will configure the reporter
it passes to run to not print stack traces for failed tests if it has a stack depth that identifies the offending
line of test code. If you prefer a short stack trace (10 to 15 stack frames) to be printed with any test failure, specify true for
shortstacks:
scala> (new ExampleSuite).execute(shortstacks = true)
For full stack traces, set fullstacks to true:
scala> (new ExampleSuite).execute(fullstacks = true)
If you specify true for both shortstacks and fullstacks, you'll get full stack traces.
The stats parameter
If you leave the stats parameter unspecified, this method will not fire RunStarting and either RunCompleted
or RunAborted events to the reporter it passes to run.
If you specify true for stats, this method will fire the run events to the reporter, and the reporter will print the
expected test count before the run, and various statistics after, including the number of suites completed and number of tests that
succeeded, failed, were ignored or marked pending. Here's how you get the stats:
scala> (new ExampleSuite).execute(stats = true)
To summarize, this method will pass to run:
testName - None if this method's testName parameter is left at its default value of null, else Some(testName).reporter - a reporter that prints to the standard outputstopper - a Stopper whose apply method always returns falsefilter - a Filter constructed with None for tagsToInclude and Set()
for tagsToExcludeconfigMap - the configMap passed to this methoddistributor - Nonetracker - a new TrackerNote: In ScalaTest, the terms "execute" and "run" basically mean the same thing and
can be used interchangably. The reason this method isn't named run is that it takes advantage of
default arguments, and you can't mix overloaded methods and default arguments in Scala. (If named run,
this method would have the same name but different arguments than the main run method that
takes seven arguments. Thus it would overload and couldn't be used with default argument values.)
Design note: This method has two "features" that may seem unidiomatic. First, the default value of testName is null.
Normally in Scala the type of testName would be Option[String] and the default value would
be None, as it is in this trait's run method. The null value is used here for two reasons. First, in
ScalaTest 1.5, execute was changed from four overloaded methods to one method with default values, taking advantage of
the default and named parameters feature introduced in Scala 2.8.
To not break existing source code, testName needed to have type String, as it did in two of the overloaded
execute methods prior to 1.5. The other reason is that execute has always been designed to be called primarily
from an interpeter environment, such as the Scala REPL (Read-Evaluate-Print-Loop). In an interpreter environment, minimizing keystrokes is king.
A String type with a null default value lets users type suite.execute("my test name") rather than
suite.execute(Some("my test name")), saving several keystrokes.
The second non-idiomatic feature is that shortstacks and fullstacks are all lower case rather than
camel case. This is done to be consistent with the Shell, which also uses those forms. The reason
lower case is used in the Shell is to save keystrokes in an interpreter environment. Most Unix commands, for
example, are all lower case, making them easier and quicker to type. In the ScalaTest
Shell, methods like shortstacks, fullstacks, and nostats, etc., are
designed to be all lower case so they feel more like shell commands than methods.

Throws TestPendingException to indicate a test is pending.
Throws TestPendingException to indicate a test is pending.
A pending test is one that has been given a name but is not yet implemented. The purpose of pending tests is to facilitate a style of testing in which documentation of behavior is sketched out before tests are written to verify that behavior (and often, the before the behavior of the system being tested is itself implemented). Such sketches form a kind of specification of what tests and functionality to implement later.
To support this style of testing, a test can be given a name that specifies one
bit of behavior required by the system being tested. The test can also include some code that
sends more information about the behavior to the reporter when the tests run. At the end of the test,
it can call method pending, which will cause it to complete abruptly with TestPendingException.
Because tests in ScalaTest can be designated as pending with TestPendingException, both the test name and any information
sent to the reporter when running the test can appear in the report of a test run. (In other words,
the code of a pending test is executed just like any other test.) However, because the test completes abruptly
with TestPendingException, the test will be reported as pending, to indicate
the actual test, and possibly the functionality it is intended to test, has not yet been implemented.
Note: This method always completes abruptly with a TestPendingException. Thus it always has a side
effect. Methods with side effects are usually invoked with parentheses, as in pending(). This
method is defined as a parameterless method, in flagrant contradiction to recommended Scala style, because it
forms a kind of DSL for pending tests. It enables tests in suites such as FunSuite or FunSpec
to be denoted by placing "(pending)" after the test name, as in:
test("that style rules are not laws") (pending)
Readers of the code see "pending" in parentheses, which looks like a little note attached to the test name to indicate
it is pending. Whereas "(pending()) looks more like a method call, "(pending)" lets readers
stay at a higher level, forgetting how it is implemented and just focusing on the intent of the programmer who wrote the code.
Execute the passed block of code, and if it completes abruptly, throw TestPendingException, else
throw TestFailedException.
Execute the passed block of code, and if it completes abruptly, throw TestPendingException, else
throw TestFailedException.
This method can be used to temporarily change a failing test into a pending test in such a way that it will
automatically turn back into a failing test once the problem originally causing the test to fail has been fixed.
At that point, you need only remove the pendingUntilFixed call. In other words, a
pendingUntilFixed surrounding a block of code that isn't broken is treated as a test failure.
The motivation for this behavior is to encourage people to remove pendingUntilFixed calls when
there are no longer needed.
This method facilitates a style of testing in which tests are written before the code they test. Sometimes you may
encounter a test failure that requires more functionality than you want to tackle without writing more tests. In this
case you can mark the bit of test code causing the failure with pendingUntilFixed. You can then write more
tests and functionality that eventually will get your production code to a point where the original test won't fail anymore.
At this point the code block marked with pendingUntilFixed will no longer throw an exception (because the
problem has been fixed). This will in turn cause pendingUntilFixed to throw TestFailedException
with a detail message explaining you need to go back and remove the pendingUntilFixed call as the problem orginally
causing your test code to fail has been fixed.

Runs this suite of tests.
Runs this suite of tests.
If testName is None, this trait's implementation of this method
calls these two methods on this object in this order:
runNestedSuites(report, stopper, tagsToInclude, tagsToExclude, configMap, distributor)runTests(testName, report, stopper, tagsToInclude, tagsToExclude, configMap)If testName is defined, then this trait's implementation of this method
calls runTests, but does not call runNestedSuites. This behavior
is part of the contract of this method. Subclasses that override run must take
care not to call runNestedSuites if testName is defined. (The
OneInstancePerTest trait depends on this behavior, for example.)
Subclasses and subtraits that override this run method can implement them without
invoking either the runTests or runNestedSuites methods, which
are invoked by this trait's implementation of this method. It is recommended, but not required,
that subclasses and subtraits that override run in a way that does not
invoke runNestedSuites also override runNestedSuites and make it
final. Similarly it is recommended, but not required,
that subclasses and subtraits that override run in a way that does not
invoke runTests also override runTests (and runTest,
which this trait's implementation of runTests calls) and make it
final. The implementation of these final methods can either invoke the superclass implementation
of the method, or throw an UnsupportedOperationException if appropriate. The
reason for this recommendation is that ScalaTest includes several traits that override
these methods to allow behavior to be mixed into a Suite. For example, trait
BeforeAndAfterEach overrides runTestss. In a Suite
subclass that no longer invokes runTests from run, the
BeforeAndAfterEach trait is not applicable. Mixing it in would have no effect.
By making runTests final in such a Suite subtrait, you make
the attempt to mix BeforeAndAfterEach into a subclass of your subtrait
a compiler error. (It would fail to compile with a complaint that BeforeAndAfterEach
is trying to override runTests, which is a final method in your trait.)

that should be excluded (tagsToExclude), when deciding which of this Suite's tests to execute.
If tagsToInclude is empty, all tests will be executed
except those those belonging to tags listed in the tagsToExclude Set. If tagsToInclude is non-empty, only tests
belonging to tags mentioned in tagsToInclude, and not mentioned in tagsToExclude
will be executed. However, if testName is Some, tagsToInclude and tagsToExclude are essentially ignored.
Only if testName is None will tagsToInclude and tagsToExclude be consulted to
determine which of the tests named in the testNames Set should be run. For more information on trait tags, see the main documentation for this trait.
If testName is None, this trait's implementation of this method
invokes testNames on this Suite to get a Set of names of tests to potentially execute.
(A testNames value of None essentially acts as a wildcard that means all tests in
this Suite that are selected by tagsToInclude and tagsToExclude should be executed.)
For each test in the testName Set, in the order
they appear in the iterator obtained by invoking the elements method on the Set, this trait's implementation
of this method checks whether the test should be run based on the tagsToInclude and tagsToExclude Sets.

MultipleFixtureSpec has been deprecated and will be removed in a future version of ScalaTest. Please use FixtureSpec with ConfigMapFixture instead.
I deprecated this trait because I decided using explicit calls to with-fixture methods is preferrable to implicitly calling them, as was recommended and made slightly less concise by this trait. You can of course continue to use the implicit conversion approach if you prefer it. To get rid of this deprecation warning, just change "MultipleFixtureSpec" to "FixtureSpec with ConfigMapFixture" in your code. - Bill Venners
