Qt Creator ManualTests DebuggerGdb

Tests using tests/manual/debugger/simple/simple.pro from Qt Creator's source repository

Test	Result	Annotation
Set breakpoint, press F5 to build and run debugger, verify that program stops at a breakpoint that you set: in main function before program is started while the program is running in dynamically loaded plugins, especially in constructors on a bit of code that was commented out. Make sure it is moved on debugger startup to the first line producing real code below that position and that it is hit there.
"Step into" a couple of times. Can you step into Qt source code (*.cpp file under QTDIR. You might need to configure source paths mapping under Tools -> Options -> Debugger -> Add Qt sources...)? (Mac: switch on 'Use Debug Versions of Frameworks' in run configuration. You need Qt sources.)
Test debugging helpers/python gdb: Do classes like QImage or std::string show beautiful information instead of the raw structure?	automated
Step through some (not all) test* functions and check whether the displayed data looks sane
Comment out the return statement inside the following functions one by one. Check whether you'll end up with a proper stack trace & locals display. testNullPointerDeref() testNullReference() testEndlessLoop(); (break manually) testEndlessRecursion(); testUncaughtException(); (not on Windows)
Test a breakpoint in a QThread: Uncomment the call to qthread::testQThread() Place a breakpoint in qthread::Thread::run() Run this in the debugger Make sure that: the breakpoint receives the right number of hits "Locals and Expressions" and "Stack" views show reasonable data, including the object names of the threads
Switch on temporarily 'Operate by Instruction' and check whether you see disassembler output and can step by instruction

Tests using tests/manual/debugger/cli-io/cli-io.pro from Qt Creator's source repository

Test	Result	Annotation
Check I/O (qDebug, std::cout, std::cerr), on Win for both Debug and Release.		stderr/stdout handling on Windows: An application needs to be built with 'console' for stderr/stdout to appear (use Creator's "Run in terminal" setting) Creator itself is built with 'console' in debug mode only. qDebug() prints to stderr for ‘console’ apps, else to the Windows debugger log, which can be shown with the DbgView utility
Check "Run in Terminal". Use Terminal for input. (Debbuging might not work on Ubuntu)
Create new project. Can you build, run and debug it?	automated
Check nothing bad happens on a simple int main() {} program with no breakpoints set	automated

Tests using tests/manual/debugger/gui/gui.pro from Qt Creator's source repository

Test	Result	Annotation
Run the project. Click the button "Crash". It should write a core file to the working directory. Depending on the operating system, you might have to set "ulimit –c unlimited" and/or disable OS-specific crash-reporting mechanisms. Attach Creator to the core file. Verify that you see a stacktrace, variable values and code markers just as if you had run the application in the debugger from the beginning.
Start the project from outside Creator, e.g. from the command line. Attach Creator to the running process. Verify that you see a stacktrace, variable values and code markers just as if you had run the application in the debugger from the beginning. You should also be able to pause/continue the execution.
Test unusual situations: Kill the running debugged program 'externally' with a signal that is neither SIGSTOP nor SIGKILL. Qt Creator should end up showing a backtrace.
Kill the stopped debugged program 'externally'. Nothing should happen immediately, on next continue or step Qt Creator should end up showing a backtrace.
Try remote debugging: start a gdbserver using e.g. gdbserver localhost:1234 ./fakevim in creator/tests/manual/fakevim on a Linux machine and connect to it
