Now, set up a school year (2005-2006) with a single term (Year):
>>> manager.ui.schoolyear.add('2005-2006', '2005-09-01', '2006-07-15')
>>> manager.ui.term.add('2005-2006', 'Year', '2005-09-01', '2006-07-15')
Set up a course:
>>> manager.ui.course.add('2005-2006', 'Physics I')
Set up persons:
>>> manager.ui.person.add('Paul', 'Carduner', 'paul', 'pwd')
>>> manager.ui.person.add('Tom', 'Hoffman', 'tom', 'pwd')
>>> manager.ui.person.add('Claudia', 'Richter', 'claudia', 'pwd')
>>> manager.ui.person.add('Stephan', 'Richter', 'stephan', 'pwd')
Set up a section with instructor and students:
>>> manager.ui.section.add('2005-2006', 'Year', 'Physics I')
>>> manager.ui.section.instructors.add('2005-2006', 'Year', 'Physics I (1)',
... ['stephan'])
>>> manager.ui.section.students.add('2005-2006', 'Year', 'Physics I (1)',
... ['tom', 'claudia', 'paul'])
Log in as teacher and go to his gradebook:
>>> stephan = browsers.stephan
>>> stephan.ui.login('stephan', 'pwd')
>>> stephan.query.link('Gradebook').click()
Add some activities to the default worksheet:
>>> stephan.query.link('Activity').click()
>>> stephan.query.id('form-widgets-title').ui.set_value('HW 1')
>>> stephan.query.id('form-widgets-category').ui.set_value('Homework')
>>> stephan.query.id('form-widgets-max').clear()
>>> stephan.query.id('form-widgets-max').ui.set_value('50')
>>> stephan.query.id('form-buttons-add').click()
>>> stephan.query.link('Activity').click()
>>> stephan.query.id('form-widgets-title').ui.set_value('Quiz 1')
>>> stephan.query.id('form-widgets-category').ui.set_value('Exam')
>>> stephan.query.id('form-buttons-add').click()
>>> stephan.query.link('Activity').click()
>>> stephan.query.id('form-widgets-title').ui.set_value('HW 2')
>>> stephan.query.id('form-widgets-category').ui.set_value('Homework')
>>> stephan.query.id('form-widgets-max').clear()
>>> stephan.query.id('form-widgets-max').ui.set_value('50')
>>> stephan.query.id('form-buttons-add').click()
>>> stephan.query.link('Activity').click()
>>> stephan.query.id('form-widgets-title').ui.set_value('Quiz 2')
>>> stephan.query.id('form-widgets-category').ui.set_value('Exam')
>>> stephan.query.id('form-buttons-add').click()
Add grades for the first three activities for Paul:
>>> stephan.ui.gradebook.worksheet.score('Paul Carduner', 'HW1', '40')
>>> stephan.ui.gradebook.worksheet.score('Paul Carduner', 'Quiz1', '90')
>>> stephan.ui.gradebook.worksheet.score('Paul Carduner', 'HW2', '45')
Add grades for the first three activities for Tom:
>>> stephan.ui.gradebook.worksheet.score('Tom Hoffman', 'HW1', '45')
>>> stephan.ui.gradebook.worksheet.score('Tom Hoffman', 'Quiz1', '80')
>>> stephan.ui.gradebook.worksheet.score('Tom Hoffman', 'HW2', '50')
Add grades for the first three activities for Claudia:
>>> stephan.ui.gradebook.worksheet.score('Claudia Richter', 'HW1', '50')

Let's create some category weights for the current worksheet. Note
that the categories are ordered alphabetically.
>>> def format_category_weight(label, value):
... return "%s: %s" % (label, repr(value))
>>> def print_category_weights(browser):
... for row in browser.query_all.css('fieldset .row'):
... label = row.query.css('.label span').text
... value = row.query.tag('input').get_attribute('value')
... print format_category_weight(label, value)
>>> stephan.query.link('Category Weights').click()
>>> print stephan.query.css('.page .header h2').text
Edit Category Weights
>>> print_category_weights(stephan)
Assignment: u''

First we'll show what happens when a value is invalid. The only valid weights
will be numbers between 0 and 100.
>>> stephan.query.id('assignment').ui.set_value('bad value')
>>> stephan.query.name('UPDATE_SUBMIT').click()
>>> print stephan.query.css('.ui-state-error').text
icon
bad value is not a valid weight.
>>> stephan.query.id('assignment').clear()
>>> stephan.query.id('assignment').ui.set_value('-1')
>>> stephan.query.name('UPDATE_SUBMIT').click()
>>> print stephan.query.css('.ui-state-error').text
icon
-1 is not a valid weight.
>>> stephan.query.id('assignment').clear()
>>> stephan.query.id('assignment').ui.set_value('101')
>>> stephan.query.name('UPDATE_SUBMIT').click()
>>> print stephan.query.css('.ui-state-error').text
icon
101 is not a valid weight.
We'll fill in valid values for Assignment, Homework and Exam. Hitting
'Submit' will succeed and return us to the gradebook. There we will
note the effect of the weighting in the Average column.
>>> stephan.query.id('assignment').clear()
>>> stephan.query.id('assignment').ui.set_value('20')
>>> stephan.query.id('exam').clear()
>>> stephan.query.id('exam').ui.set_value('50')
>>> stephan.query.id('homework').clear()
>>> stephan.query.id('homework').ui.set_value('30')
>>> stephan.query.name('UPDATE_SUBMIT').click()
>>> stephan.ui.gradebook.worksheet.pprint()

| Carduner | Paul | 40 | 90 | 45 | | 175.0 | 88.1% |
| Hoffman | Tom | 45 | 80 | 50 | | 175.0 | 85.6% |
| Richter | Claudia | 50 | 95 | 50 | | 195.0 | 96.9% |
+-----------+------------+-----+-------+-----+-------+-------+-------+
Finally, we'll test hitting the 'Cancel' button. It should return to the
gradebook without changing the weights.

Let's add a new Assignment activity:
>>> stephan.query.link('Activity').click()
>>> stephan.query.id('form-widgets-title').ui.set_value('Experiment')
>>> stephan.query.id('form-widgets-category').ui.set_value('Assignment')
>>> stephan.query.id('form-widgets-max').clear()
>>> stephan.query.id('form-widgets-max').ui.set_value('10')
>>> stephan.query.id('form-buttons-add').click()
Let's grade the new assignment for Paul and Tom:
>>> stephan.ui.gradebook.worksheet.score('Paul Carduner', 'Exper', '9')
>>> stephan.ui.gradebook.worksheet.score('Tom Hoffman', 'Exper', '7')
>>> stephan.query.name('UPDATE_SUBMIT').click()
Note how the Average changed for Paul and Tom, but not for Claudia:
>>> stephan.ui.gradebook.worksheet.pprint()

| Carduner | Paul | 40 | 90 | 45 | | 9 | 184.0 | 88.5% |
| Hoffman | Tom | 45 | 80 | 50 | | 7 | 182.0 | 82.5% |
| Richter | Claudia | 50 | 95 | 50 | | | 195.0 | 96.9% |
+-----------+------------+-----+-------+-----+-------+-------+-------+-------+
Now, let's give Homeworks the 100% of weight:
>>> stephan.query.link('Category Weights').click()
>>> stephan.query.id('assignment').clear()
>>> stephan.query.id('exam').clear()
>>> stephan.query.id('homework').clear()
>>> stephan.query.id('homework').ui.set_value('100')
>>> stephan.query.name('UPDATE_SUBMIT').click()
Let's go back to check that the values of the weights were stored
correctly:
>>> stephan.query.link('Category Weights').click()
>>> print_category_weights(stephan)

The Averages have changed:
>>> stephan.ui.gradebook.worksheet.pprint()
+----------+
| *Sheet1* |

+-----------+------------+-----+-------+-----+-------+-------+-------+--------+
| Last Name | First Name | HW1 | Quiz1 | HW2 | Quiz2 | Exper | Total | Ave. |

| Hoffman | Tom | 45 | 80 | 50 | | 7 | 182.0 | 95.0% |
| Richter | Claudia | 50 | 95 | 50 | | | 195.0 | 100.0% |
+-----------+------------+-----+-------+-----+-------+-------+-------+--------+
Let's test that explicit zeros are saved:
>>> stephan.query.link('Category Weights').click()
>>> stephan.query.id('assignment').clear()
>>> stephan.query.id('assignment').ui.set_value('0.0')
>>> stephan.query.id('essay').clear()

>>> stephan.query.id('lab').ui.set_value('0.0')
>>> stephan.query.id('project').clear()
>>> stephan.query.id('project').ui.set_value('0.0')
>>> stephan.query.name('UPDATE_SUBMIT').click()

Since all these weights are zero, they shouldn't affect the averages:
>>> stephan.ui.gradebook.worksheet.pprint()
+----------+
| *Sheet1* |
+----------+
+-----------+------------+-----+-------+-----+-------+-------+-------+--------+
| Last Name | First Name | HW1 | Quiz1 | HW2 | Quiz2 | Exper | Total | Ave. |

+-----------+------------+-----+-------+-----+-------+-------+-------+--------+
| Carduner | Paul | 40 | 90 | 45 | | 9 | 184.0 | 85.0% |
| Hoffman | Tom | 45 | 80 | 50 | | 7 | 182.0 | 95.0% |
| Richter | Claudia | 50 | 95 | 50 | | | 195.0 | 100.0% |
+-----------+------------+-----+-------+-----+-------+-------+-------+--------+
Divide by zero bug
------------------
Until we fixed the bug, there was a case that crashed the gradebook where there
was a score for a non-weighted category but no score for a weighted one. To
prove that the bug has been fixed, we will remove all the scores for Claudia
and add one for the 'Experiment' activity whose category, 'Assignment', has a
weight of zero.
>>> stephan.ui.gradebook.worksheet.score('Claudia Richter', 'HW1', '0')
>>> stephan.ui.gradebook.worksheet.score('Claudia Richter', 'Quiz1', '0')
>>> stephan.ui.gradebook.worksheet.score('Claudia Richter', 'HW2', '0')
>>> stephan.ui.gradebook.worksheet.score('Claudia Richter', 'Exper', '50')
>>> stephan.query.name('UPDATE_SUBMIT').click()
It didn't crash. We see that Claudia has an average of zero even though she
has a score for 'Experiment' because it has a weight of zero.
