gcovr: How to use Cygwin gcovr package?

Question

I'm using gcov already to get code coverage results. I want to use gcovr. I've installed the gcovr package from Cygwin.

Now, I've never used Python. I'm confused because I've got C:\cygwin\lib\python2.7\site-packages\gcovr with init.py, init.pyc and init.pyo files

Under C:\cygwin\bin I've got a gcovr file and also python.exe

I ran python.exe from command prompt and it says Python 2.7.13 (default, Mar 14 2017, 23:27:55) [GCC 5.4.0] on cygwin (is this what I have to use for gcovr?)

I tried >>>python2.7 gcovr with the full gcovr path mentioned above and I get

SyntaxError: invalid syntax

I tried >>>gcovr and I get

Traceback (most recent call last):

File (stdin); line 1, in (module)

NameError: name 'gcovr' is not defined

I went through the help utility and looked at all the modules, gcovr was one of them.

I've seen usage like ../../../scripts/gcovr -r but I don't have a scripts folder.

What am I missing? What steps should I follow?

Try gcovr -r ./ and gcovr -r ./ --branches from the root folder where you have your .gcno and .gcda files to get the summary of line and branch coverage respectively
