// because the storage service will have been initialized and the
|
|
// do_GetService() call in ServiceInitializer::Run will succeed. So we need a
|
|
// way to force it to run before all the other storage gtests. As it happens,
|
|
// gtest has a concept of "death tests" that, among other things, run before
|
|
// all non-death tests. By merely using a "DeathTest" suffix here this becomes
|
|
// a death test -- even though it doesn't use any of the normal death test
|
|
// features -- which ensures this is the first storage test to run.
