This will contain the weekly reports, I just came to know my branch is available publicly, it is called soc-2020-testing-frameworks and can be viewed here.
Week 1 (18-24 May):
Went through the Generate and Deform modifiers for surveying, as to how the framework should be built with special focus on helper objects and vertex groups.
Survey of mesh operators ( focus on user interaction )
Checked reproducible(ness) of the modifiers.
Support for other object types like Curves, surface, text.
Simplified inspection of Physics modifiers.
Build a working prototype for the automatic creation of blend objects.
Sheet 3: Survey
Week 2 (June 1-7):
Plan of Action:
Complete the prototype to make it usable by fellow developers.
Worked on including remaining mesh modifiers.
The ones I was trying to test required “Object Operators”, so I added support for modifiers which require operators. e.g “Bind” for Surface Deform
Added default tests for Wave and Ocean, and dummy* tests for Surface deform and mesh deform.
*Dummy test - there is no actual deformation, hence the test cannot fail, which is necessary.
Week 6 (June 29-July 5):
Add support for imitating user input, using shape keys or animation.
Covering the remaining of mesh modifiers. (make real tests as opposed to dummy ones).
Will cover Hook, Surface deform, Mesh deform, Warp, Laplacian Deform.
*Note 1- this does not involve Physics Modifiers, they would be covered separately.
*Note 2- Curves modifiers has been shifted to next week.
Yayy! Finally done with mesh modifiers*. Now we can actually test the deformation using the animation and shape keys. So I have included the tests for the above-said modifiers. (look at the previous report)

Plan of Action
Week 7 (July 6-July 12):
This week will be dedicated to extend the framework for Curves (pretty much in sync with the timeline)
Improvements in the work done until now based on the review(s).
*Note- this doesn’t include Physics modifier, and there were some complications with Remesh and Smooth Corrective (they will either be skipped for now or worked upon in the background)
Week 7 (July 6-July 12):
It was a slow week, some college stuff came up and there were some personal issues. Also I got stuck on the review like having a coder’s block, I have discussed with the mentor, I did get some idea still got nothing working.
And I recently pushed the code to my remote branch.
Will update if something significant happens over the weekend.
Weekend-
added the run_test_using_name feature to the test cases and made some minor improvements as per the review.
as of now we can have tests that can imitate user input and support object operators, it is fully functional now (it is being reviewed again as I type this)
Next plan
Get started with building the framework for testing Curves Modifiers.
I have lot of things to take care of this week, so documenting alongside, this is the ongoing week. Week 9 (July 20-July 26):
Tried testing Fluid modifiers, it is giving different “baked” result when testing inside blender as compared to testing it using a script. Found, it was because the test objects were produced in a different blender version and were being tested in a different blender version. Therefore the test was failing.
Adding Deform tests, Armature modifier for Curves cannot be assigned to Automatic weights (hence no vertex groups are created) so Bone envelopes is used.
New developments - Wave modifier is not regressable, it fails randomly. It passes after I freshly add it but fails on the next day or the day after. I suspect same thing as Fluid, different versions of Blender.
Worked with the Particle system, it is not reproducible as far as I tested, will give a final conclusion soon.
Plan of Action
The plan is to finish with Physics modifiers, firstly, I am planning to test Explode modifier, but it requires Particle system, so if that is reproducible, I will write an interface to interact with it, and write a test for it which will cover both I guess.
And I have some research paper work to take care of in the upcoming weeks, I will try my best to finish with the Deliverable 2 this week only and probably a meeting with the mentors(after finishing up I guess).
Hello Calra, I have a script available that can automate the process of rigging any arbitrary curve with an armature and envelope weights. In my addon the file ops_misc.py has a CreateBonesFromCurve operator that does this. When the addon is installed, this operator is available from the Add Armature menu when a curve is selected. Please feel free to use it if it will make creating the tests easier.
@Josephbburg I will have a look at it, if I would like to add more complicated tests. But I would like to keep it simple, and don’t mind a bad-rigged curve for testing , the modifier should work correctly, that’s what I am after. Thank you for both the things : )
Added a class and test for Particle systems, reproducible with a script.
Added a class and test for Dynamic Paint, its combined with Fluids.
Had a meeting with mentors, there have been changes with the next Deliverable and how to spend the next 3-4 weeks.
Had another meeting with Habib to discuss possible implementation of creating a generic class which can handle Physics modifiers as well.
Plan of Action for the upcoming week
To clean and polish the framework, refactoring the existing classes and combining all of them and creating a new Modifier Spec that can handle Physics modifiers.
Main focus would be on to solve the problem of parsing through a nested dictionary to apply the modifier parameters.
Finally worked on Object Generator Script, changed the style to Object Oriented, had difficulty including Vertex Group support, was unable to pinpoint the problem of “where did all the other objects go?” so that part has been removed for now.
The tests for Cloth Pressure and Self Collision were removed due to non-reproducibility on other systems.
Coming Week- The Finale Week
Have a summary meeting with mentors on how or when to make the merge.
Work on the review on both D8507 (Habib) and D8674 (Habib and Campbell)
D8507 is the Framework and Tests and D8674 is Test Object Generator Script
If extra time, add few more tests for Physics modifiers.
Work on the Work Project Submission (Final Report) which needs to be submitted to Google.
, the modifier should work correctly, that’s what I am after. Thank you for both the things : )
