Nice work @Jeezman, I get this error in the console when I try to run the test

    console.log
      TypeError: Cannot read properties of undefined (reading 'status')
          at MainStore.<anonymous> (/Users/raphaelosazeeyerin/Desktop/Sphinx/sphinx-tribes/frontend/app/src/store/main.ts:1385:20)

Can you take a look? it has as a result of response.status being undefined when you called saveBounty from the test, and is there a reason you preferred Jest Mock to Sinon Stub?

We already use jest mock in the codebase

sphinx-tribes/frontend/app/src/__test__/__mockFn__/useHistory.ts

Lines 3 to 6 in 2bbe6fb

	jest.mock('react-router-dom', () => ({
	...jest.requireActual('react-router-dom'),
	useHistory: () => ({
	push: mockHistoryPush
