Automated testing

To run tests in an automated fashion, the AIMMS Unit Test framework comes with a Python script that you can call from the command line to run all, or selected tests. You can copy the script to your project folder by calling the procedure aimmsunit::CopyPythonScript. The arguments of the Python script are:

  • the AIMMS version to be used to run the test (e.g., the test script will automatically download the AIMMS version from the AIMMS download site and unpack it in the aimms subfolder of the location from which you run the script
  • the architecture to run the test on (x86 / x64 on Windows, or x64 on Linux)
  • the project folder, relative to the working folder, containing the AIMMS project to test
  • the name of the project file (e.g. MyProject.aimms)
  • optionally, the names of the test suites to test (--suites argument), if not specified all test suites will be run.

You can use this script, for instance, when checking in a new version of your project into your version control system.

Requirements for the Python script

To successfully run the script, you should have the following software installed on your test machine:

  • Python 2.7
  • Python requests module installed (install via pip install requests)
  • 7-zip (Windows only, installed in C:\Program Files\7-zip\7z.exe


When checking in a new version of the AIMMS Unit Test library into our internal Gitlab repository, a build script will automatically be run to

  • build all external DLLs that come with the AIMMS Unit Test library,
  • run the unit test suites defined by the AIMMS Unit Test library project itself, and
  • if successful, package the AIMMS Unit Test library, and upload it to the AIMMS Library repository.

The following output of running the test suites is returned during the second step

If any of the tests fail, the python script will list the contents of the file log/AimmsUnit.xml to show the individual results of all tests.
