Detailed Description

Log handle for saving messages for testing.

Temporarily replace the given logger with this function. This removes ANSI sequences and replaces pointer-like strings with 0x0.

You can use the CELER_LOG_SCOPED environment variable to print the captured log messages as they are written.

ScopedLogStorer scoped_log_{&celeritas::world_logger()};
CELER_LOG(info) << "captured";
scoped_log_.print_expected();
EXPECT_TRUE(scoped_log_.empty()) << scoped_log_;
