Testing

To ensure that the functionality of the PolarRoute codebase remains consistent throughout the development cycle a testing strategy has been developed, which can be viewed in the document test/testing_strategy.md. This includes a collection of test files which should be run according to which part of the codebase has been altered in a pull request. Please consult the testing strategy to determine which tests need to be run.

• [ ] My changes have not altered any of the files listed in the testing strategy

• [ ] My changes result in all required regression tests passing without the need to update test files.

list which files have been altered and include a pytest.txt file for each of the tests required to be run

The files which have been changed during this PR can be listed using the command

git diff --name-only 1.1.x

• [ ] My changes require one or more test files to be updated for all regression tests to pass.

include pytest.txt file showing which tests fail.
include reasoning as to why your changes cause these tests to fail.

Should these changes be valid, relevant test files should be updated.
include pytest.txt file of test passing after test files have been updated.
