/**
* <p>
* Convenient superclass for JUnit 3.8 based tests depending on a Spring
* context. The test instance itself is populated by Dependency Injection.
* </p>
* <p>
* Really for integration testing, not unit testing. You should <i>not</i>
* normally use the Spring container for unit tests: simply populate your POJOs
* in plain JUnit tests!
* </p>
* <p>
* This supports two modes of populating the test:
* </p>
* <ul>
* <li>Via Setter Dependency Injection. Simply express dependencies on objects
* in the test fixture, and they will be satisfied by autowiring by type.
* <li>Via Field Injection. Declare protected variables of the required type
* which match named beans in the context. This is autowire by name, rather than
* type. This approach is based on an approach originated by Ara Abrahmian.
* Setter Dependency Injection is the default: set the
* {@code populateProtectedVariables} property to {@code true} in
* the constructor to switch on Field Injection.
* </ul>

/**
* Convenient base class for JUnit 3.8 based tests that should occur in a
* transaction, but normally will roll the transaction back on the completion of
* each test.
*
* <p>This is useful in a range of circumstances, allowing the following benefits:
* <ul>
* <li>Ability to delete or insert any data in the database, without affecting
* other tests
* <li>Providing a transactional context for any code requiring a transaction
* <li>Ability to write anything to the database without any need to clean up.
* </ul>
*
* <p>This class is typically very fast, compared to traditional setup/teardown
* scripts.
*
* <p>If data should be left in the database, call the {@link #setComplete()}
* method in each test. The {@link #setDefaultRollback "defaultRollback"}
* property, which defaults to "true", determines whether transactions will
* complete by default.
*
* <p>It is even possible to end the transaction early; for example, to verify lazy
* loading behavior of an O/R mapping tool. (This is a valuable away to avoid
* unexpected errors when testing a web UI, for example.) Simply call the
* {@link #endTransaction()} method. Execution will then occur without a
* transactional context.
*
* <p>The {@link #startNewTransaction()} method may be called after a call to
* {@link #endTransaction()} if you wish to create a new transaction, quite
* independent of the old transaction. The new transaction's default fate will
* be to roll back, unless {@link #setComplete()} is called again during the
* scope of the new transaction. Any number of transactions may be created and
* ended in this way. The final transaction will automatically be rolled back
* when the test case is torn down.
*
* <p>Transactional behavior requires a single bean in the context implementing the
* {@link PlatformTransactionManager} interface. This will be set by the
* superclass's Dependency Injection mechanism. If using the superclass's Field
* Injection mechanism, the implementation should be named "transactionManager".
* This mechanism allows the use of the
* {@link AbstractDependencyInjectionSpringContextTests} superclass even when
* there is more than one transaction manager in the context.
*
* <p><b>This base class can also be used without transaction management, if no
* PlatformTransactionManager bean is found in the context provided.</b> Be
* careful about using this mode, as it allows the potential to permanently
* modify data. This mode is available only if dependency checking is turned off
* in the {@link AbstractDependencyInjectionSpringContextTests} superclass. The
* non-transactional capability is provided to enable use of the same subclass
* in different environments.
