LLDB module which provides the abstract base class of lldb test case.
The concrete subclass can override lldbtest.TesBase in order to inherit the
common behavior for unitest.TestCase.setUp/tearDown implemented in this file.
The subclass should override the attribute mydir in order for the python runtime
to locate the individual test cases when running as part of a large test suite
or when running each test case as a separate python invocation.
./dotest.py provides a test driver which sets up the environment to run the
entire of part of the test suite . Example:
# Exercises the test suite in the types directory....

"""
This abstract base class is meant to be subclassed. It provides default
implementations for setUpClass(), tearDownClass(), setUp(), and tearDown(),
among other things.
Important things for test class writers:
- Overwrite the mydir class attribute, otherwise your test class won't
run. It specifies the relative directory to the top level 'test' so
the test harness can change to the correct working directory before
running your test.
- The setUp method sets up things to facilitate subsequent interactions
with the debugger as part of the test. These include:
- populate the test method name
- create/get a debugger set with synchronous mode (self.dbg)
- get the command interpreter from with the debugger (self.ci)
- create a result object for use with the command interpreter
(self.res)
- plus other stuffs
- The tearDown method tries to perform some necessary cleanup on behalf
of the test to return the debugger to a good state for the next test.
These include:
- execute any tearDown hooks registered by the test method with
TestBase.addTearDownHook(); examples can be found in
settings/TestSettings.py
- kill the inferior process associated with each target, if any,
and, then delete the target from the debugger's target list
- perform build cleanup before running the next test method in the
same test class; examples of registering for this service can be
found in types/TestIntegerTypes.py with the call:
- self.setTearDownCleanup(dictionary=d)
- Similarly setUpClass and tearDownClass perform classwise setup and
teardown fixtures. The tearDownClass method invokes a default build
cleanup for the entire test class; also, subclasses can implement the
classmethod classCleanup(cls) to perform special class cleanup action.
- The instance methods runCmd and expect are used heavily by existing
test cases to send a command to the command interpreter and to perform
string/pattern matching on the output of such command execution. The
expect method also provides a mode to peform string/pattern matching
without running a command.
- The build methods buildDefault, buildDsym, and buildDwarf are used to
build the binaries used during a particular test scenario. A plugin
should be provided for the sys.platform running the test suite. The
Mac OS X implementation is located in plugins/darwin.py.
