Testing Cloudy and pyNublado

Cloudy installation test run

In order to test that your Cloudy installation works as expected, put in the path to your Cloudy executable and run it:

~/c17.03/source/cloudy.exe

  • Type “test” then press Enter twice

  • Cloudy should print some output, which ends with “Cloudy exited OK”

Running Cloudy manually on a model

To test if a given .in file is compatible with Cloudy, you may want to run Cloudy independently:

  1. Create a [name].in file

  2. Navigate to the folder where the .in file is located

  3. Execute Cloudy from that directory

~/c17.03/source/cloudy.exe [name].in

Testing

pyNublado comes with a number of tests for the pytest framework. They can be found in the tests/ directory. To run the tests with pytest:

  1. Install pytest, e.g. via pip install pytest or conda install pytest

  2. Navigate to the tests subdirectory cd tests

  3. Run tests pytest test.py -v, the -v (or -vv) flag is optional for increased verbosity

The tests do the following:

  • check if the Cloudy path in src/usr_settings.py is the correct path of the Cloudy installation by running a test model.in

  • check if the output of CLOUDY is ok (“Cloudy exited OK”)

  • it creates the file structure src.manager.QueueManager() expects and runs 4 models on multiple cpus to test the pipeline.

  • check if the stellar atmosphere model specified in src/user_settings.py is installed (see BPASS installation)
