8 Test cases for Touch Events v2 Recommendation
9 https://w3c.github.io/touch-events/
10
11 These tests are based on Mozilla-Nokia-Google's single-touch tests.
12
13 The primary purpose of the tests in this document is checking that the creat eTouch and
14 createTouchList interfaces of the Touch Events APIs are correctly implemente d.
15 Other interactions are covered in other test files.
