It is the V2 of [1], rebased and with added tests.
To allow test (with console record), I replace the debug uart function used to display the dropped messages printascii() by the console generic function puts().
This function allows to support all the features defined in console.c (as DEBUG_UART, PRE_CONSOLE_BUFFER, CONSOLE_RECORD) without duplicate them (no more nedd to test CONFIG_DEBUG_UART for example).
PS: I don't sure that the added trace added for test in arch/sandbox/cpu/start.c = "sandbox: starting..." is not disturbing. see patch 5 = "test: add test for dropped trace before log_init"

Changes in v2: - Add test for LOGL_FORCE_DEBUG (NEW) - add test to count the dropped messages (NEW) - replace printascii by console puts, remove test on CONFIG_DEBUG_UART - Add test of displayed messages requested before log_init (NEW) - update gd test in console function puts and putc (cosmetic) - Record all messages in console, even when dropped (NEW) - added test for content of dropped messages (NEW)
Patrick Delaunay (9): test: add LOGL_FORCE_DEBUG flags support in log tests log: don't build the trace buffer when log is not ready test: log: add test for dropped messages log: use console puts to output trace before LOG init test: add test for dropped trace before log_init console: remove duplicated test on gd value console: allow to record console output before ready test: log: add test for console output of dropped messages log: call vsnprintf only when it is needed to emit trace
