# Internals:
|
||||
# * The tests run in sequence & the system keeps track of all failures to print at the end.
|
||||
# * BUILD directory is set to default BUILD_DIR_BASE
|
||||
# * The "print_status" function both prints a status line to the log and keeps track of which test is running.
|
||||
# * Calling the "failure" function prints a failure message to the log and also adds to the list of failures to print at the end.
|
||||
# * The function "assert_built" tests for a file relative to the BUILD directory.
|
||||
# * The function "take_build_snapshot" can be paired with the functions "assert_rebuilt" and "assert_not_rebuilt" to compare file timestamps and verify if they were rebuilt or not since the snapshot was taken.

# To add a new test case, add it to the end of the run_tests function. Note that not all test cases do comprehensive cleanup
|
||||
# (although very invasive ones like appending CRLFs to all files take a copy of the esp-idf tree.)
