Contents of ipc/ipdl/test/cxx/README.txt: | |||
To add a new IPDL C++ unit test, you need to create (at least) the | |||
following files (for a test "TestFoo"): | |||
- PTestFoo.ipdl, specifying the top-level protocol used for the test | |||
- TestFoo.h, declaring the top-level parent/child actors used for | |||
the test | |||
- TestFoo.cpp, defining the top-level actors | |||
- (make sure all are in the namespace mozilla::_ipdltest) | |||
Next | |||
- add PTestFoo.ipdl to ipdl.mk | |||
- append TestFoo to the variable IPDLTESTS in Makefile.in | |||
The IPDL test harness will try to execute |testFooParentActor->Main()| | |||
to kick off your test. Make sure you define |TestFooParent::Main()|. | |||
If your test passes its criteria, please call | |||
|MOZ_IPDL_TESTPASS("msg")| and "exit gracefully". | |||
If your tests fails, please call |MOZ_IPDL_TESTFAIL("msg")| and "exit | |||
ungracefully", preferably by abort()ing. | |||
If all goes well, running | |||
make -C $OBJDIR/ipc/ipdl/test/cxx | |||
will update the file IPDLUnitTests.cpp (the test launcher), and your | |||
new code will be built automatically. | |||
You can launch your new test by invoking | |||
make -C $OBJDIR/ipc/ipdl/test/cxx check | |||
If you want to launch only your test, run | |||
cd $OBJDIR/dist/bin | |||
./run-mozilla.sh ./ipdlunittest TestFoo | |||
For a bare-bones example of adding a test, take a look at | |||
PTestSanity.ipdl, TestSanity.h, TestSanity.cpp, and how "TestSanity" | |||
is included in ipdl.mk and Makefile.in. | |||
