Move test.ipynb from root directory into some other place for testing

Please can we move test related files into the src/tests folder.

The problem right now is the test that uses this is verifying that export doesn't add unnecessary cd commands when a file is in the root of the workspace. The root of the workspace is where the test.ipynb file is.

It is really goofy there. Maybe put it in src/tests and move it out just for the actual test execution?

The root of the workspace is where the test.ipynb file is.

Currently when integration tests run, the cwd is tests directory...
If you need a custom cwd, we can change that on devops.
