## Testing
The parsers can become quite complicated and maintaining them without
systematic testing can become troublesome. Unit tests provide one way to
test each parseable quantity and python has a very good [library for
unit testing](https://docs.python.org/2/library/unittest.html). When the parser
supports a new quantity it is quite fast to create unit tests for it. These
tests will validate the parsing, and also easily detect bugs that may rise when
the code is modified in the future.
systematic testing is impossible. There are general tests that are
performed automatically in the scala layer for all parsers. This is essential,
but can only test that the data is outputted in the correct format and
according to some general rules. These tests cannot verify that the contents
are correct.
In order to truly test the parser output, unit testing is needed. Unit tests
provide one way to test each parseable quantity and python has a very good
[library for unit testing](https://docs.python.org/2/library/unittest.html).
When the parser supports a new quantity it is quite fast to create unit tests
for it. These tests will validate the parsing, and also easily detect bugs that
may rise when the code is modified in the future.
