Historically, Spring's JUnit 3.8 TestCase class hierarchy supported
programmatic transaction management of "test-managed transactions" via
the protected endTransaction() and startNewTransaction() methods in
AbstractTransactionalSpringContextTests.
The Spring TestContext Framework (TCF) was introduced in Spring 2.5 to
supersede the legacy JUnit 3.8 support classes; however, prior to this
commit the TCF has not provided support for programmatically starting
or stopping the test-managed transaction.
This commit introduces a TestTransaction class in the TCF that provides
static utility methods for programmatically interacting with
test-managed transactions. Specifically, the following features are
supported by TestTransaction and its collaborators.
- End the current test-managed transaction.
- Start a new test-managed transaction, using the default rollback
semantics configured via @TransactionConfiguration and @Rollback.
- Flag the current test-managed transaction to be committed.
- Flag the current test-managed transaction to be rolled back.
Implementation Details:
- TransactionContext is now a top-level, package private class.
- The existing test transaction management logic has been extracted
from TransactionalTestExecutionListener into TransactionContext.
- The current TransactionContext is stored in a
NamedInheritableThreadLocal that is managed by
TransactionContextHolder.
- TestTransaction defines the end-user API, interacting with the
TransactionContextHolder behind the scenes.
- TransactionalTestExecutionListener now delegates to
TransactionContext completely for starting and ending transactions.
