Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
Complex classes like test_Apex often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.

| 4 | Notes |
||
| 5 | ----- |
||
| 6 | Whenever function outputs are tested against hard-coded numbers, the test |
||
| 7 | results (numbers) were obtained by running the code that is tested. Therefore, |
||
| 8 | these tests below only check that nothing changes when refactoring, etc., and |
||
| 9 | not if the results are actually correct. |
||
| 10 | |||
| 11 | These results are expected to change when IGRF is updated. |
