Ideally we would write each source next to each test to make tests more
readable, but clustering all tests to use a common test file really
helps boost the runtime of the end2end tests now that we reuse the same
page between tests that share the same code.
This CL refactos the tests to mostly use one shared test file. Doing so
speeds up tests between 2x-4x depending on the test.
