NAME
gen_html -- generate html pages describing test coverage
SYNOPSIS
gen_html merged.db
DESCRIPTION
This script generates html pages given the name of a merged.db
file. This file should have been created after running all
your project's tests with instrumented executables. Here is a
general overview of the process:
replace your calls to g++ with calls to cov++
make clean, then make, then run all your tests
merge your coverage files like this:
covmerge.exe `find * -name '*.covexp'` >merged.db
use gen_html to build html pages:
gen_html merged.db
Once gen_html has done its job, you will have a new directory
named 'coverage_html'. This directory will contain a variety
of numbered .html files. There will also be an 'index.html'
file. Point your browser at that and you will see a
collection of html files describing the test coverage
information and more importantly, you will see annotated copies
of your source code.
An annotated sourcefile will look like this:
#include <stdio.h>
int main()
+{
+ printf("hello world");
+ exit(0);
}
Where the lines beginning with '-' have been instrumented but
not executed. Lines beginning with '+' were executed. Lines
with never were not executed. Global variables are never
shown as instrumented due to the limitations of the
instrumentation technique.
