After I’ve done all the testings, I found that these three tests are useful to test my mobile app: Treetest, Image Card Sort, and First-Click Test.

Treetest: Treetest was the test that I had the most fun with. It took the longest out of all three tests(2min 7sec) but it was direct and easy to find by clicking one category each from the droplist provided to finish the task. In my opinion, I think this test was the most useful out of three tests because it was straight-forward(other ones are straight-forward too but this method is going step-by-step to inform people to match the right result.) and it matches the results the most.

Image Card Sort: Image Card Sort was the test that I find interesting. I just had to finish the task by looking at the provided images and sort out the categories. However, according to the result, I found it surprising that people have been categorized differently. Each image was created at least 28 different categories by different people. This means that it gives a variety of answers but also means it is indirect and has to cover so many contents at one.

First-Click Test: First-Click Test was the test that also had fun with. It took the shortest(1 min 35 sec) to finish and I just had to select the category from the given prototype to finish the task. According to the result, the percentage is biased on one category, which means it was direct.
