Investigate testing React apps with ses enabled
See original GitHub issueWhat is the Problem Being Solved?
Jest is the default testing environment for create-react-app, but it does not work out of the box with ses. When calling lockdown, the following error occurs:
Unexpected intrinsic intrinsics.ArrayBuffer.__proto__ at %FunctionPrototype%
(context: https://github.com/Agoric/agoric-sdk/commit/2abb793a9444a105409f896e19989a33bd24ea6a)
Description of the Design
Ava is the more supported testing environment for ses, so we should attempt to switch a fresh create-react-app to use Ava instead of Jest and document the complexity of such work. If this works, there will at least be a way to write unit tests for react apps that use ses. Then, take a deeper dive into Jest to figure out where it’s breaking, and perhaps open an issue for that.
Acceptance Criteria
Establish a working pattern for writing react tests in ses (in either Ava or Jest). If Jest is not supported, decide on the priority and feasibility of implementing support for it.
