Try bashtest. It`s simple way to test your scripts. For example, you have do-some-work.sh which change some config files. For example, add new line PASSWORD = 'XXXXX' to config file /etc/my.cfg.

You write bash commands line by line and then check output.

Install:

pip3 install bashtest

Create tests is a just writing bash commands.

File test-do-some-work.bashtest:

# run the script  
$ ./do-some-work.sh > /dev/null

# testing that the line "PASSWORD = 'XXXXX'" is in the file /etc/my.cfg   
$ grep -Fxq "PASSWORD = 'XXXXX'" /etc/my.cfg && echo "YES"
YES

Run tests:

bashtest *.bashtest
