## Introduction
test_git_update.sh performs functional tests on git_update.sh to verify that it is behaving as planned.
## Tests
The script consists in nine tests. The three first ones test the cloning and the following test the updating of git_update.sh.
Each test consists of calling git_update.sh, eventually after some modifications, and compare the result with the expected result. The comparison is done by *_check functions, which modify each a boolean *_result.
If all booleans of checks conducted are true, then the boolean case* is also true and the test is a success.
