## README
|
||
|
|
# In order to use this script to make a coverage profile of the memgraph binary
|
||
|
|
# you should create a new build directory in the project root (eg.
|
||
|
|
# build_coverage) and in that directory you should execute
|
||
|
|
# `../tools/coverage_memgraph`.
|
||
|
|
#
|
||
|
|
# This script will run `cmake`, `make` and then start the `memgraph` process.
|
||
|
|
# When you wish to stop recording coverage data you should terminate the
|
||
|
|
# memgraph process using C-c. Then the coverage will be processed and opened in
|
||
|
|
# a browser.
|
||
|
|
#
|
||
|
|
# All parameters passed to this script will be forwarded to the memgraph
|
||
|
|
# process.
|
||
|
|
#
|
||
|
|
# After the binary is compiled the first time, this script *WON'T* recompile
|
||
|
|
# memgraph. It does it for the first time just for convenience.

||
|
