Anybody know of one?
Actually, I have a feeling that emacs understands a standard format
for errors, which would make it really easy to implement this by
having the coverage tool print results in that format -- anybody know
where to find the details?
I also wonder if some kind of graphical display might be useful
somehow, having been inspired by this: http://kcachegrind.sourceforge.net/
(really, I just like the pretty pictures :)

compilation-error-regexp-alist. The simplest format to remember is
filename:linenu mber:message
I'm not sure what you're after though. Code coverage tools generally emit
annotated listings, not compiler-like output. What would you like it to do,
emit file:line:msg info for the start of each run of lines which weren't
covered? How would you get any context showing you what lines in the region
had been executed at least once?

Thanks.

Yes.
How would you get any context showing you what lines in the region
had been executed at least once?
Why would I want to?
I haven't done any proper code-coverage analysis before, but I
had imagined just doing:
while 1:
uncovered = run_coverage_to ol(my_code)
if not uncovered: break
jump_to(uncover ed[0])
think()
write_test()
John How would you get any context showing you what lines in the region

John> Why would I want to?
For me, analyzing code coverage consists of studying the code in the region
around the uncovered line(s). Knowing which lines in the area have and
haven't been covered helps me analyze what's missing in my test coverage.

I am probably going to start a war now... but so be it :)
I just want to hear what all you guys who eat pythons for breakfast use
for python coding. Currently I use Kate, but I would really like an IDE
with debugger and a source browser (ie. one the I can use to browse
through modules etc. when looking for just the right curses stuff and such
- I am a newcomer to Python).

Good morning,
I am using doxygen to create a reference manual for C source code. Do
you know of a way to similarly create a texinfo reference manual (which
I would like to use in emacs info-mode, BTW) ? Maybe this is possible
through one of doxygen's already supported output formats.
Kind regards,

Hi,
I have a set of C source files and I need a tool which can add probes
and then dynamically trace the execution and print the results (The C
source code does not have any printf statements).
The purpose of the tool is to add test cases for unit testing and then
see the statement/branch coverage for them.
Thanks,

I am searching for a good profiling tool for C# which can be easily
embedded into Visual Studio.
My objective is to measure the times and counts of every method in my

If used the Coverage Tool of TestDriven.Net (http://www.testdriven.net/)
which worked fine if I have defined any Unit test-cases.

Hello,
We are looking for any testing tool that is capable of checking code
coverage for C,C ++ and Java code. Or at least for C and C++. We want
to know how much (percentage) of our code written on C/C++ is covered
in terms of function calls and line calls. We tried Rational
PureCoverage. It's excellent but has some limitations in our case.
Any idea would be greatly appreciated.

Hi list.
What strategies do you use to ensure correctness of new code?
Specifically, if you've just written 100 new lines of Python code, then:
1) How do you test the new code?
2) How do you ensure that the code will work correctly in the future?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
