This README file describes the files and directories related to the Python test
|
|
|
|
suite under the current 'test' directory.
|
|
|
|
|
|
|
|
o dotest.py
|
|
|
|
|
|
|
|
Provides the test driver for the test suite. To invoke it, cd to the 'test'
|
|
|
|
directory and issue the './dotest.py' command or './dotest.py -v' for more
|
|
|
|
verbose output. '.dotest.py -h' prints out the help messge.
|
|
|
|
|
|
|
|
A specific naming pattern is followed by the .py script under the 'test'
|
|
|
|
directory in order to be recognized by 'dotest.py' test driver as a module
|
|
|
|
which implements a test case, namely, Test*.py.

|
|
|
Some example usages:
|
|
|
|
|
|
|
|
1. ./dotest.py -v . 2> ~/Developer/Log/lldbtest.log0
|
|
|
|
This runs the test suite and directs the run log to a file.
|
|
|
|
|
|
|
|
2. LLDB_LOG=/tmp/lldb.log GDB_REMOTE_LOG=/tmp/gdb-remote.log ./dotest.py -v . 2> ~/Developer/Log/lldbtest.log
|
|
|
|
This runs the test suite, with logging turned on for the lldb as well as
|
|
|
|
the process.gdb-remote channels and directs the run log to a file.
|
|
|
|
|

|
|
|
o lldbtest.py
|
|
|
|
|
|
|
|
Provides an abstract base class of lldb test case named 'TestVase', which in
|
|
|
|
turn inherits from Python's unittest.TestCase. The concrete subclass can
|
|
|
|
override lldbtest.TestBase in order to inherit the common behavior for
|
|
|
|
unittest.TestCase.setUp/tearDown implemented in this file.
|
|
|
|
|
|
|
|
To provide a test case, the concrete subclass provides methods whose names
|
|
|
|
start with the letters test. For more details about the Python's unittest
|
|
|
|
framework, go to http://docs.python.org/library/unittest.html.
|
|
|
|
|
|
|
|
./command_source/TestCommandSource.py provides a simple example of test case
|
|
|
|
which overrides lldbtest.TestBase to exercise the lldb's 'command source'
|
|
|
|
command. The subclass should override the attribute 'mydir' in order for the
|
|
|
|
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.
|
|
|
|
|
|
|
|
The doc string provides more details about the setup required for running a
|
|
|
|
test case on its own. To run the whole test suite, 'dotest.py' is all you
|
|
|
|
need to do.
|
|
|
|
|
|
|
|
o subdirectories of 'test'
|
|
|
|
|
|
|
|
Most of them predate the introduction of the python test suite and contain
|
|
|
|
example C/C++/ObjC source files which get compiled into executables which are
|
|
|
|
to be exercised by the debugger.
|
|
|
|
|
|
|
|
For such subdirectory which has an associated Test*.py file, it was added as
|
|
|
|
part of the Python-based test suite to test lldb functionality.
|
|
|
|
|
|
|
|
Some of the subdirectories, for example, the 'help' subdirectory, do not have
|
|
|
|
C/C++/ObjC source files; they were created to house the Python test case which
|
|
|
|
does not involve lldb reading in an executable file at all.
|

|
|
|
o make directory
|
|
|
|
|
|
|
|
Contains Makefile.rules, which can be utilized by test cases to write Makefile
|
|
|
|
based rules to build native binaries.
|
|
|
|
|

|
|
|
o plugins directory
|
|
|
|
|
|
|
|
Contains platform specific plugin to build binaries with dsym/dwarf debugging
|
|
|
|
info. Other platform specific functionalities may be added in the future.

|
|
|
o unittest2 directory
|
2010-08-06 07:47:51 +08:00
|
|
|
|
|
|
|
Many new features were added to unittest in Python 2.7, including test
|
|
|
|
discovery. unittest2 allows you to use these features with earlier versions of
|
|
|
|
Python.
|
|
|
|
|
|
|
|
It currently has unittest2 0.5.1 from http://pypi.python.org/pypi/unittest2.
|
2010-08-07 05:07:38 +08:00
|
|
|
Version 0.5.1 of unittest2 has feature parity with unittest in Python 2.7
|
|
|
|
final. If you want to ensure that your tests run identically under unittest2
|
|
|
|
and unittest in Python 2.7 you should use unittest2 0.5.1.
|
|
|
|
|
|
|
|
Later versions of unittest2 include changes in unittest made in Python 3.2 and
|
|
|
|
onwards after the release of Python 2.7.

|
|
o dotest.pl
|
|
|
|
|
|
|
|
In case you wonder, there is also a 'dotest.pl' perl script file. It was
|
|
|
|
created to visit each Python test case under the specified directory and
|
|
|
|
invoke Python's builtin unittest.main() on each test case.
|
|
|
|
|
|
|
|
It does not take advantage of the test runner and test suite functionality
|
|
|
|
provided by Python's unitest framework. Its existence is because we want a
|
|
|
|
different way of running the whole test suite. As lldb and the Python test
|
|
|
|
suite become more reliable, we don't expect to be using 'dotest.pl' anymore.
|
|
|
|
|

|
|
|
Note: dotest.pl has been moved to the attic directory.

o Profiling dotest.py runs
|
|
|
|
|
|
|
|
I used the following command line thingy to do the profiling on a SnowLeopard
|
|
|
|
machine:
|
|
|
|
|
|
|
|
$ DOTEST_PROFILE=YES DOTEST_SCRIPT_DIR=/Volumes/data/lldb/svn/trunk/test /System/Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/cProfile.py -o my.profile ./dotest.py -v -w 2> ~/Developer/Log/lldbtest.log
|
|
|
|
|
|
|
|
After that, I used the pstats.py module to browse the statistics.
