Alire/ALR's testsuite

This directory intends to host a comprehensive testsuite for Alire/ALR as a library/tool. The testsuite framework currently requires a Python 3 interpreter with the e3-testsuite package (from PyPI) installed.

You also must have GNAT and GPRBuild in your PATH. You can install these with, for example:

alr install gnat_native=<version_x> gprbuild=<version_y> --prefix=<dir>

and add <dir>/bin to your PATH, or

cd <dir>
alr get gnat_native=<version_x> gprbuild=<version_y>

and add <dir>/gnat_native_<version_x>_(...)/bin and <dir>/gprbuild_<version_y>_(...)/bin to your PATH.

Assuming your environment already has a Python 3 interpreter and has virtualenv installed, here is a quick cookbook to run the testsuite:

# Create a virtualenv (prefix to install packages)
# The exact command varies from one Linux distribution to another:
# virtualenv, virtualenv3, virtualenv-3.10, ...
$ virtualenv my-virtual-env

# Update your environment to use it
$ source my-virtual-env/bin/activate

# Install e3-testsuite and all its dependencies
$ pip install -r requirements.txt

# You should now be able to run the testsuite (make sure you built alr and
# made it available with your PATH):
$ ./run.py

Creating tests

All tests are based on running a Python script. There are these test drivers:

  • python-script: run in host in both sandboxed and shared build mode.
    • The build mode can be narrowed down with the build_mode attribute.
  • docker-wrapper: run in a pristine docker Ubuntu image in shared build mode.

Environment variables

The following variables can be used to modify testsuite behavior.

For ALIRE_TESTSUITE_DISABLE_* variables, their mere existence activates their function, no matter their value, or lack of one.

  • ALIRE_TESTSUITE_DISABLE_DISTRO: when defined, alr will be configured to not detect the system distribution and fall back to unknown distribution.

  • ALIRE_TESTSUITE_DISABLE_DOCKER: when defined, alr will skip tests that require Docker (which are enabled by default if Docker is detected).

  • ALIRE_TESTSUITE_DISABLE_NETWORK_TESTS: when defined, tests that require non-local network use will be skipped.

  • ALIRE_TESTSUITE_ENABLE_LOCAL_TESTS: when defined, tests that are intended to be run locally only by the Alire developer team will not be skipped.

Example disabling Docker tests for a single run on Bash:

$ ALIRE_TESTSUITE_DISABLE_DOCKER= ./run.sh
