/**
|
||||
* @fileoverview Test Subprocess Helper Macros
|
||||
*
|
||||
* These macros may be used to run unit tests in a subprocess. It's
|
||||
* particularly useful when testing code that causes the process to die:
|
||||
*
|
||||
* TEST(term, test) {
|
||||
* SPAWN(fork);
|
||||
* raise(SIGUSR1);
|
||||
* TERMS(SIGUSR1);
|
||||
* }
|
||||
*
|
||||
* The default action for both EXITS() and TERMS() is _Exit(0), unless
|
||||
* an EXPECT_FOO() macro failed, in which case the status is non-zero.
|
||||
*
|
||||
* TEST(my, test) {
|
||||
* SPAWN(fork);
|
||||
* // do stuff
|
||||
* EXITS(0);
|
||||
* }
|
||||
*
|
||||
* You can also nest subprocesses:
|
||||
*
|
||||
* TEST(exit, test) {
|
||||
* SPAWN(fork);
|
||||
* SPAWN(vfork);
|
||||
* _Exit(2);
|
||||
* EXITS(2);
|
||||
* _Exit(1);
|
||||
* EXITS(1);
|
||||
* }
