             Summary: Add possibility to check transaction state for test only purpose.
                 Key: IGNITE-19663
                 URL: https://issues.apache.org/jira/browse/IGNITE-19663
             Project: Ignite
          Issue Type: Wish
          Components: general
    Affects Versions: 3.0.0-beta1
            Reporter: Evgeny Stanilovsky


For now there huge number of tests (for example ItSqlAsynchronousApiTest#implicitTransactionsStates) that use reflection for detection transaction completeness. This is erroneous way. So required *test only* functionality that can shows call number difference between TxManager.begin(*boolean*) and Transaction.(commit|rollback).
Another words: required functionality that detects that no transactions without *Transaction.(commit|rollback)* call are present in appropriate TxManager.

Pseudo code, as i can see it

{noformat}
TxManager txManagerInstance = ... (so this is a questionable how can we get it without reflection)
tx = txManagerInstance.begin(RW or RO);
...
some code, probably sql corner cases...
call_sql_operation_with_OUTER_tx(tx, ...);
tx.commit();

call_sql_operation_with_INNER_tx(null, ...); (tx will burn and finalize internally)
....

assertTrue(txManagerInstance.no_transactions_without_commit_or_rollback_call())
{noformat}
