Update the functions that print the test totals at the end of a selftest to include a warning message when skipped tests are detected. The message advises users that skipped tests may indicate missing configuration options and suggests enabling them to improve coverage. Signed-off-by: Laura Nao <laura.nao@xxxxxxxxxxxxx> --- This patch follows up on a previous discussion[1] and aims to highlight skipped tests for the user's attention.
