# Introduction
performance_tests contains tests who compare the memory and bandwidth usage of different Git commande in order to compare them.
functional_tests contains tests who verify that git_update.sh is behaving as expected.
Both rely on the same test repository that is created by test_repo_creation.sh. 
Both have to be run from their directory because they rely on relative paths.

# Creation of the test repository
The script test_repo_creation.sh creates a remote/$REPO_NAME repository.

### branch main 			
commit  sample0 1M created
commit  sample1 1M created
commit  sample3 5M created
commit  sample4 1M created
commit  sample3 5M deleted (tag : tagging_point)
[if  -s is selected] commit adding $SUB_NAME module
### branch secondary
commit  sample0 1M created 
commit  sample1 1M created
commit  sample2 500K created

Which gives the latest state:
### branch main
sample0	1M
sample1	1M
sample4	1M
