Looks good to me! These changes seem pretty simple, and I didn't spot any major issues. I did leave a few small suggestions, but nothing critical, particularly in light of most of the changes being to test code.

The changes to leverage TypeScript more effectively look good overall. I added a note about the use of non-null assertions and in general suggest being cautious with those. They can mask real problems especially when used in tests and could make the tests less useful if the actual code stops providing the variable or data you are asserting should exist. Aside from that I don't see any security or other blocking issues to be concerned about. Thanks!
