A library of shell script functions and a shell testing tools
leveraging both bats-core and docker. N2ST purposes is
to speed up shell script development and improve code reliability.

_{Maintainer Luc Coupal}

Just clone the norlab-shell-script-tools as a submodule in your project repository (ie the superproject), in an arbitrary directory eg.: my-project/utilities/.

Procedure

cd <my-project>
mkdir utilities

git submodule init

git submodule \
  add https://github.com/norlab-ulaval/norlab-shell-script-tools.git \
  utilities/norlab-shell-script-tools

# Traverse the submodule recursively to fetch any sub-submodule
git submodule update --remote --recursive --init

# Commit the submodule to your repository
git add .gitmodules
git add utilities/norlab-shell-script-tools
git commit -m 'Added norlab-shell-script-tools submodule to repository'

To clone your repository and its submodule at the same time, use

git clone --recurse-submodules

Be advise, submodules are a snapshot at a specific commit of the norlab-shell-script-tools repository. To update the submodule to its latest commit, use

[sudo] git submodule update --remote --recursive --init [--force]

Notes:

• Add the --force flag if you want to reset the submodule and throw away local changes to it. This is equivalent to performing git checkout --force when cd in the submodule root directory.
• Add sudo if you get an error such as error: unable to unlink old '<name-of-a-file>': Permission denied

To set the submodule to point to a different branch, use

cd <the/submodule/directory>
git checkout the_submodule_feature_branch_name

and use the --recurse-submodules flag when switching branch in your main project

cd <your/project/root>
git checkout --recurse-submodules the_feature_branch_name

# Change the `.git/objects` permissions
cd <main/project/root>/.git/objects/
chown -R $(id -un):$(id -gn) *
#       <yourname>:<yourgroup>

# Share the git repository (the submodule) with a Group
cd ../../<the/submodule/root>/
git config core.sharedRepository group
# Note: dont replace the keyword "group"

This should solve the problem permanently.

• Functions are available with and without the n2st:: prefix for maintaining legacy v1 API support. Be advised, they will only be available in their n2st:: prefixed form in release >= v3.

Try this in norlab-shell-script-tools root

source import_norlab_shell_script_tools_lib.bash
n2st::norlab_splash "NorLab rule 🦾"  https://github.com/norlab-ulaval

• Most code in this repository is tested using bats-core
• Most code is well documented: each script header and each function definition
• Go to src/function_library for shell script functions:
  • docker utilities
  • general utilities
  • prompt utilities
  • teamcity utilities
  • terminal splash
• Go to src/utility_scripts for utility script:
  • docker tools installer
  • script that output the host architecture and os
  • script that output which python version

To import the library functions, execute the following

cd <path/to/norlab-shell-script-tools>

bash import_norlab_shell_script_tools_lib.bash
# All norlab-shell-script-tools functions are now sourced in your current shell. 

Note: N2ST functions are prefixed with n2st, i.e.: n2st::<function_name>

1. Copy the norlab-shell-script-tools/tests/tests_template/ directory in your main project top directory and rename it, e.g. tests_template/ → tests_shell/ ( recommand using the convention tests/);

2. Add project test code in this new test directory.

   • See test_template.bats for bats test implementation examples;
   • Usage: duplicate test_template.bats and rename it using the convention test_<logic_or_script_name>.bats;
   • Note: That file is pre-configured to work out of the box, just missing your test logic.

3. Use the copied script run_bats_core_test_in_n2st.bash to execute your tests. They will be executed in isolation in a docker container tailormade for testing shell script or command level logic in your codebase.

• Note: test directory nesting is suported
• By default, it will search for the tests/ directory. Pass your test directory name as an argument otherwise.

Assuming that the superproject (i.e. the project which have cloned N2ST as a submodule) as the following structure, tests/ would be containing all the .bats files

To execute your superproject shell scripts bats test via 'norlab-shell-script-tools' library, just run the following from your repository root

cd "<path/to/superproject>/tests"
bash run_bats_core_test_in_n2st.bash ['<test-directory>[/<bats-test-file-name.bats>]' ['<image-distro>']]

Arguments:

• ['<test-directory>'] The directory from which to start test, default to 'tests'
• ['/<bats-test-file-name.bats>'] A specific bats file to run, default will run all bats file in the test directory

See tests/tests_template/run_bats_core_test_in_n2st.bash for details.
