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

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

+(async function(testRunner) {

This is not relevant to the test, lets remove it.

What do you mean? It's in expectations file.

+    window.addEventListener('contextmenu', logEvent);
+  `);
+
+  var events = [
+    {
+      'type': 'mousePressed',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 200
+    },
+    {
+      'type': 'mouseReleased',
+      'button': 'left',
+      'clickCount': 1,
+      'x': 100,
+      'y': 200
+    },
+    {
+      'type': 'mouseMoved',
+      'modifiers': 8, // shift
+      'x': 50,
+      'y': 150
+    },
+    {
+      'type': 'mousePressed',
+      'button': 'right',
+      'clickCount': 1,
+      'x': 100,
+      'y': 200
+    },
+    {
+      'type': 'mouseReleased',
+      'button': 'right',
+      'clickCount': 1,
+      'x': 100,
+      'y': 200
+    }
+  ];
+
+  for (var event of events) {
+    var msg = await dp.Input.dispatchMouseEvent(event);
+    if (msg.error)
+      testRunner.log('Error: ' + msg.error.message);
+  }
+
+  testRunner.log(await session.evaluate(`window.logs.join('\\n')`));
+  testRunner.completeTest();
+})

nit: semi-colon

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

Actually, putting semicolon here would break the harness, which expects the test
body to evaluate into function.
Any ideas on how to improve that are welcome!
