With this small project<\/a> now about to be finished, I want to describe the way in which I tested the program, before moving on to newer projects (something more in the game-creation way instead of analyzing game outputs…).<\/p>\n

One obvious way of testing if the tool is even remotely doing what it is supposed to do is by loading a save game in the game and testing out some combinations that the tool calculated. Another way is to do the test more automated: get a list of possible fusions, and test all of them against the fusion algorithms in the tool. There are some choices to get such data. One is the fusion list<\/a> by Tony Ye. Unfortunately, that list contains a lot of errors, for example, it lists a lot of fusions which are impossible, very visibly where Persona which require triangle spread fusions are created with normal spread according to the list. A better choice appears to be eserikto’s<\/a> list of fusions.<\/p>\n

What I did was create a small class which can parse this list and which provides all combinations of Persona found in this list to a unit test. I then feed these combinations into my own fusion algorithms and check if the results differ. The effect was quite good, as I found several spots where my fusion logic didn’t match that of the game. In other cases, I found out that eserikto’s list also contains some errors, for example, several combinations which, according to the list, should result in Alilat, actually result in Skadi. Also, the same-arcana fusions required some fiddling until they resulted in the same Persona the game expects. The recent finding<\/a> how save games can be modified also proved very useful to create target Persona with arbitrary levels for checking the results.<\/p>\n

Overall, I’m now quite confident that the tool will correctly predict the fusions. The insight I gained from this part of the project is that I should really go more into the direction of test-driven development<\/a>, as writing that unit test showed a lot of small errors I hadn’t cought earlier.<\/p>\n","protected":false},"excerpt":{"rendered":"
