Unit Testing & Transactions

[VBCoder]

I'd like to use transactions to add unit testing to my vB mods & code. That is, I'd like to tell vB "Start a transaction. Now, use the DM API to do things. Now roll that transaction back" So the tests haven't disturbed anything.

Is there anyway to do this? How? (PHP4/MySQL4, but could switch to PHP5 if necessary)

From memory, the transactional things are dealt with by mysql, not php.

But MyISAM doesnt support transactional queries.

Have a look at the following URL's:

http://dev.mysql.com/doc/mysql/en/an...rent-apis.html

Like Merk already say, you can not use this with MyISAM tables. For InnoDB it is basically:

Start transaction:
[sql]BEGIN TRANSACTION;[/sql]

Then end the transaction with one of the following:
[sql]COMMIT;[/sql]
or:
[sql]ROLLBACK;[/sql]

Sorry for not being more clear. I know how to do transactions in SQL. My question is, could I somehow wrap vB's actions in transactions. Something like:

mysql_query('BEGIN TRANSACTION');
build_new_post();
mysql_query('ROLLBACK');

or, even better:

$vbulletin->database->begin_transaction();
$dm = init_datamanager(...)
$dm->...
$vbulletin->database->rollback_transaction();

Note: I'm working from memory, so my syntax isn't exact
