git grep TEST_ENSHURE

gives quite some uses of this misspelled macro that is defined here and there as:

#if OSL_DEBUG_LEVEL > 0
#define TEST_ENSHURE(c, m)   OSL_ENSURE(c, m)
#else
#define TEST_ENSHURE(c, m)   OSL_VERIFY(c)
#endif

These definitions should be removed, and most of the uses of TEST_ENSHURE should be changed directly to OSL_ENSURE(), like:

-    TEST_ENSHURE( xSMgr.is(), "excomp error 0" );
+    OSL_ENSURE( xSMgr.is(), "excomp error 0" );

There is a small catch - OSL_VERIFY() evaluates the condition _always_, regardless of the debug level, so in case the condition is something more advanced than xSMgr.is(), you might need to use OSL_VERIFY() instead of OSL_ENSURE().  If in doubt, please consult the libreoffice@lists.freedesktop.org mailing list :-)
