Tests

Fix the Code 2

This is a follow up to Fix the Code 1.

Write tests for your Fix the Code 1 code for the following cases and save it in a file called test_granger_analysis_code.py (remember that the file has to start with test_ for nose to find it). Make any corrections/improvements that need to be made to the code so that all of your tests pass.

gc_content()

1. Sequence represented by upper case string
2. Sequence represented by lower case string
3. Sequence represented by mixed case string
4. Sequence represented by multiline string

get_size_class()

In an email accompanying your “updated” code, Dr. Granger indicated that the specifications for the earlength size classes were:

1. extralarge: earlength >= 15
2. large: 10 <= earlength < 15
3. medium: 8 <= earlength < 10
4. small: earlength < 8

Write tests to check:

1. that each case is working when the numbers are in the range,
2. the edge cases of 8, 10, and 15, and
3. what happens if non-numerical values are passed to the function (e.g., a string from a header row that didn’t get removed).
