If the test suite is misconfigured when it's run (a bad regexp, wrong test directory, etc.), the test suite may not discover any tests. When this happens, the test runner exits happily because no tests failed: ``` Ran 0 tests in 0.000s RESULT: PASSED (0 passes, 0 failures, 0 errors, 0 skipped, 0 expected failures, 0 unexpected successes) ``` Change this to return an error so the misconfiguration can be more easily detected. Verified that `lldb-dotest -p TestDoesNotExist.py` successfully fails. Reviewed By: JDevlieghere Differential Revision: https://reviews.llvm.org/D85169

"""

|
A simple testing framework for lldb using python's unit testing framework.
|
|
|
|
Tests for lldb are written as python scripts which take advantage of the script
|
|
bridging provided by LLDB.framework to interact with lldb core.
|
|
|
|
A specific naming pattern is followed by the .py script to be recognized as
|
|
a module which implements a test scenario, namely, Test*.py.
|
|
|
|
To specify the directories where "Test*.py" python test scripts are located,
|
|
you need to pass in a list of directory names. By default, the current
|
|
working directory is searched if nothing is specified on the command line.
|
|
|
|
Type:
|
|
|
|
./dotest.py -h
|
|
|
|
for available options.

Examples:
|
|
|
|
This is an example of using the -f option to pinpoint to a specific test class
|
|
and test method to be run:
|
|
|
|
$ ./dotest.py -f ClassTypesTestCase.test_with_dsym_and_run_command
|
|
----------------------------------------------------------------------
|
|
Collected 1 test
|
|
|
|
test_with_dsym_and_run_command (TestClassTypes.ClassTypesTestCase)
|
|
Test 'frame variable this' when stopped on a class constructor. ... ok
|
|
|
|
----------------------------------------------------------------------
|
|
Ran 1 test in 1.396s
|
|
|
|
OK
|
|
|
|
And this is an example of using the -p option to run a single file (the filename
|
|
matches the pattern 'ObjC' and it happens to be 'TestObjCMethods.py'):
|
|
|
|
$ ./dotest.py -v -p ObjC
|
|
----------------------------------------------------------------------
|
|
Collected 4 tests
|
|
|
|
test_break_with_dsym (TestObjCMethods.FoundationTestCase)
|
|
Test setting objc breakpoints using '_regexp-break' and 'breakpoint set'. ... ok
|
|
test_break_with_dwarf (TestObjCMethods.FoundationTestCase)
|
|
Test setting objc breakpoints using '_regexp-break' and 'breakpoint set'. ... ok
|
|
test_data_type_and_expr_with_dsym (TestObjCMethods.FoundationTestCase)
|
|
Lookup objective-c data types and evaluate expressions. ... ok
|
|
test_data_type_and_expr_with_dwarf (TestObjCMethods.FoundationTestCase)
|
|
Lookup objective-c data types and evaluate expressions. ... ok
|
|
|
|
----------------------------------------------------------------------
|
|
Ran 4 tests in 16.661s
|
|
|
|
OK
|
|
|
|
Running of this script also sets up the LLDB_TEST environment variable so that
|
|
individual test cases can locate their supporting files correctly. The script
|
|
tries to set up Python's search paths for modules by looking at the build tree
|
|
relative to this script. See also the '-i' option in the following example.
|
|
|
|
Finally, this is an example of using the lldb.py module distributed/installed by
|
|
Xcode4 to run against the tests under the 'forward' directory, and with the '-w'
|
|
option to add some delay between two tests. It uses ARCH=x86_64 to specify that
|
|
as the architecture and CC=clang to specify the compiler used for the test run:
|
|
|
|
$ PYTHONPATH=/Xcode4/Library/PrivateFrameworks/LLDB.framework/Versions/A/Resources/Python ARCH=x86_64 CC=clang ./dotest.py -v -w -i forward
|
|
|
|
Session logs for test failures/errors will go into directory '2010-11-11-13_56_16'
|
|
----------------------------------------------------------------------
|
|
Collected 2 tests
|
|
|
|
test_with_dsym_and_run_command (TestForwardDeclaration.ForwardDeclarationTestCase)
|
|
Display *bar_ptr when stopped on a function with forward declaration of struct bar. ... ok
|
|
test_with_dwarf_and_run_command (TestForwardDeclaration.ForwardDeclarationTestCase)
|
|
Display *bar_ptr when stopped on a function with forward declaration of struct bar. ... ok
|
|
|
|
----------------------------------------------------------------------
|
|
Ran 2 tests in 5.659s
|
|
|
|
OK
|
|
|
|
The 'Session ...' verbiage is recently introduced (see also the '-s' option) to
|
|
notify the directory containing the session logs for test failures or errors.
|
|
In case there is any test failure/error, a similar message is appended at the
|
|
end of the stderr output for your convenience.
|
|
|
|
ENABLING LOGS FROM TESTS
|
|
|
|
Option 1:
|
|
|
|
Writing logs into different files per test case::
|
|
|
|
$ ./dotest.py --channel "lldb all"
|
|
|
|
$ ./dotest.py --channel "lldb all" --channel "gdb-remote packets"
|
|
|
|
These log files are written to:
|
|
|
|
<session-dir>/<test-id>-host.log (logs from lldb host process)
|
|
<session-dir>/<test-id>-server.log (logs from debugserver/lldb-server)
|
|
<session-dir>/<test-id>-<test-result>.log (console logs)
|
|
|
|
By default, logs from successful runs are deleted. Use the --log-success flag
|
|
to create reference logs for debugging.
