http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=12671 --- Comment #15 from Kyle M Hall <kyle@bywatersolutions.com> --- Created attachment 37341 --> http://bugs.koha-community.org/bugzilla3/attachment.cgi?id=37341&action=edit [PASSED QA] Bug 12671: Guess next serial date when there are several issues per unit This guess uses the following algorithm 1/ Get the number of days remaining from first issue of this unit of time until the end of the unit of time (using 7 days for week, 28 for month and 365 for year) 2/ Divide it by the number of issues per unit 3/ Take the integer part of the result, this is the number of days to add to previous serial published date This patch also try to guess the date of the first issue of a unit of time. Before that, it was: - for week: monday of week - for month: 1st day of month - for year: 1st day of year Now it uses firstacquidate. Example: firstacquidate = 1970-01-07 (wednesday) unit = week issuesperunit = 2 (2 issues per week) From wednesday to sunday, there are 4 days so we add 2 days to get the next date. The next dates should be: - 1970-01-09 (+ 2 days) - 1970-01-14 (wednesday of next week) - 1970-01-16 (+ 2 days) - ... and so on Test plan: 1/ Go to numbering pattern creation page (Serials -> Manager numbering patterns -> New numbering pattern) 2/ In "Test prediction pattern" fieldset, set subscription length to 50 issues (this avoid to compute the next 1000 dates, which can take time) 3/ Fill first issue publication date 4/ Choose the frequency you want to test 5/ click on "Test pattern" button 6/ Check that the dates are correct 7/ Repeat steps 3-7 until you think you have tested enough cases Interesting frequencies to test: - 1/day - 1/week - 2/week - 6/week (firstacquidate should be monday or tuesday, or the generated dates will be the same for all the week) - 1/month - 2/month - 3/month - 1/year - 2/year - 3/year ---------------- Sign off report: ---------------- -Followed the test plan. Unit tests work. Also trying some more strange frequencies with our librarians: 5/year, 43/year, 10/year. -Received all serials for a subscription and found no errors. -Received some serials with frequency 2/month pre-patch, getting publication date as 1st of every month for each magazine. Having applied the patch, publication dates started working mid-subscription for new magazines. -Works well and fine!
