How to test savu plugin

Tunhe Zhou

1. set github local repository, follow this instruction: https://savu.readthedocs.io/en/latest/dev_guides/dev_github/
2. make the plugins in the folder of plugin, for example: hilbert_filter.py
3. change the savu path to the github savu folder:
   export SAVUHOME=/home/btq48787/github/Savu
4. then
   module load savu
   savu_config
   list
   the new plugin should show in the list
5. create a simple process list, for example with only NxtomoLoader and the new plugin. save it outside the github folder somewhere.
6. run savu with the test process list and test data in /home/btq48787/github/Savu/test_data/data/24737.nxs
7. If everything is fine. Open an example test file in /home/btq48787/github/Savu/savu/test/travis/plugin_tests/filter_tests
   Use it as template to make a process_test python file for the new plugin.
   save the process_list nxs file to /home/btq48787/github/Savu/test_data/test_process_lists
   in terminal window:
   test_setup.sh
   python the_new_process_test.py
   If it runs through, then it's fine. We can push it on to github.
8. git status
   it should show that we have 3 more files now: one python for new plugin, one nxs for process list, one python for test plugin
   git add all the files
   git status
   they should look green now
   git commit -m "message for the change"
   git pull upstream master
   to update to the newest version from the diamond light source. If there were a lot of changes. might need to test again to see if the plugin works
   git push origin master
   push the changes to the master branch of my fork.
9. on github webpage, pull request to diamond for changes
