[DevTools] Migrate inspector-protocol/{input,network} tests to new harness

third_party/WebKit/LayoutTests/inspector-protocol/input/emulateTouchFromMouseEvent.js

+(async function(testRunner) {
+  let {page, session, dp} = await testRunner.startBlank(``);
+
+  await session.evaluate(`
+    var logs = [];
+    function log(text) {
+      logs.push(text);
+    }
+
+    const expectedEventCount = 5;

lets un-const this and set it to -1.

[dgozman, 2017/06/26 23:22:07]

Done.

+    var eventCount = 0;
+    var resolve;
+    var gotEventsPromise = new Promise(f => resolve = f);
+
+    function logEvent(event) {
+      event.preventDefault();

[allada, 2017/06/26 22:02:53]

Lets add an assert here like:

console.assert(expectedEventCount > 0);

[dgozman, 2017/06/26 23:22:07]

I am a bit hesitant on this - expecting flakes due to more events happening.

+      log('-----Event-----');
+      log('type: ' + event.type);
+      if (event.shiftKey)
+        log('shiftKey');
+      log('----Touches----');
+      for (var i = 0; i < event.touches.length; i++) {
+        var touch = event.touches[i];
+        log('id: ' + i);
+        log('pageX: ' + touch.pageX);
+        log('pageY: ' + touch.pageY);
+        log('radiusX: ' + touch.radiusX);
+        log('radiusY: ' + touch.radiusY);
+        log('rotationAngle: ' + touch.rotationAngle);
+        log('force: ' + touch.force);
+      }
+      eventCount++;
+      if (eventCount === expectedEventCount)
+        resolve(logs.join('\\n'));
+    }
+
+    window.addEventListener('touchstart', logEvent, {passive: false});
+    window.addEventListener('touchmove', logEvent, {passive: false});
+    window.addEventListener('touchend', logEvent);
+    window.addEventListener('touchcancel', logEvent);
+  `);
+
+  var events = [
+    {
+      'type': 'mousePressed',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 200
+    },
+    {
+      'type': 'mouseMoved',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 250
+    },
+    {
+      'type': 'mouseReleased',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 250
+    },
+    {
+      'type': 'mouseMoved',

[allada, 2017/06/26 22:02:53]

Add comment here saying something like:

// Should be ignored by the event listeners.

[dgozman, 2017/06/26 23:22:07]

Done.

+      'button': 'none',
+      'modifiers': 8, // shift
+      'x': 50,
+      'y': 150
+    },
+    {
+      'type': 'mousePressed',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 200
+    },
+    {
+      'type': 'mouseMoved',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 250
+    },
+    {
+      'type': 'mouseReleased',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 250
+    }
+  ];
+

[allada, 2017/06/26 22:02:53]

lets add:

await session.evaluateAsync('expectedEventCount = ' + (events.length - 1)); //
One of the mouseMoved events should be ignored.

This should help reduce the chance of people in the future forgetting to change
the expectedEventCount in the future.

[dgozman, 2017/06/26 23:22:07]

Nice idea! Done.

+  await dp.Page.enable();
+  await dp.Page.setTouchEmulationEnabled({enabled: true});
+
+  var time = Number(new Date()) / 1000;
+  for (var index = 0; index < events.length; index++) {
+    var event = events[index];
+    event.timestamp = time + index;
+    var msg = await dp.Input.emulateTouchFromMouseEvent(event);
+    if (msg.error)
+      testRunner.log('Error: ' + msg.error.message);
+  }
+
+  testRunner.log(await session.evaluateAsync('gotEventsPromise'));
+  testRunner.completeTest();
+})
