[TYPO3-dev] PHPUnit_Util_GlobalState::restoreGlobals destroys DB-connection (Typo3 4.5.37)

[Christian Stüdemann]

Dear all,

running a Selenium test with runTestInSeparateProcess=NULL, 
inIsolation=NULL, backupGlobals=NULL lets the 
PHPUnit_Framework_TestCase::runBare() method call 
PHPUnit_Util_GlobalState::backupGlobals before the test run and 
PHPUnit_Util_GlobalState::restoreGlobals after the test run in order to 
backup and restore all global variables, because they might be changed 
by the test run.

The backup and/or restore of the global variables does not work 
properly. After "restoreGlobals()" the DB-connection stored in 
GLOBALS['TYPO3_DB'] is 0 (i.e. not existing any more), thus all later 
DB-calls are crashing.

Seems to be a bug from my point of view. What do you recommend?
a) Report it as a bug? Is it really a bug?
b) Run Selenium with runTestInSeparateProcess=TRUE?
c) Run Selenium with inIsolation=TRUE?
d) Run Selenium with backupGlobals=FALSE?
e) Add 'TYPO3_DB' to the test's backupGlobalsBlacklist?

Thank's a lot for your support and have a nice day,
Christian
