Could you wrap this line at line 80? Our style guide[1] requires it.

[nhiroki, 2015/07/10 08:38:57]

"https://test.com/" is a real domain. Could you change this like
https://codereview.chromium.org/1224083008/ ?

+                self.postMessage('navigate() can navigate cross origin client');

[nhiroki, 2015/07/10 08:38:57]

"can navigate to a cross origin URL" ?

+                self.postMessage('navigate() result: ' + c);
+            }).then(runNextTestOrQuit);

+        client.navigate('test.html').catch(function(e) {
+            self.postMessage('navigate() can not navigate without a user interaction');

[nhiroki, 2015/07/10 08:38:57]

I think that the spec doesn't require a user interaction for navigate(). Could
you remove "synthesizeNotificationClick()" pattern from these tests?

+            self.postMessage('navigate() error is ' + e.name);
+            return client;
+        }).then(runNextTestOrQuit);

+    function testNavigateInvalidURL(client) {
+        synthesizeNotificationClick().then(function() {
+            client.navigate('http://[test].com').catch(function(e) {
+                self.postMessage('navigate() can not navigate an invalid url');

[nhiroki, 2015/07/10 08:38:57]

"navigate to an invalid url"

+                self.postMessage('navigate() error is ' + e.name);
+                return client;
+            }).then(runNextTestOrQuit);

+                self.postMessage('navigate() can not navigate view-source scheme');
