Casperjs test if page opens

问题

It can be done with pure phantomjs like this:

var page = require('webpage').create();
var address = 'http://google.com/';
page.open(address, function(status) {
  if (status !== 'success') {
    console.log('FAIL to load the address');
  } else {
    console.log('SUCCESS');
  }
  phantom.exit();
});

but I'd like it to support casperjs test command. The best I came up with is:

casper.test.begin("Hello, Test!", 1, function(test) {
    var page = require('webpage').create();
    var address = 'http://google_doesnotexist.com/';
    page.open(address, function(status) {
        test.assert(status == 'success');
        //phantom.exit();
        test.done();
    });
});

it works fine if page really opens, but the script does not stop at all if the page does not open.

Apart from your own answer, you can explicitly check the status through the status function:

casper.start("http://www.example.com/", function() {
    test.assert(this.status().currentHTTPStatus == 200);
});

or even easier by using the tester module as you already do this:

casper.start("http://www.example.com/", function() {
    test.assertHttpStatus(200);
});

There is no example with function argument in casperjs docs, but I've guessed it right:)

casper.test.begin('Page opens fine', 1, function suite(test) {
    casper.start("http://www.google_nononon.com/", function(result) {
        //console.log(status);
        //require('utils').dump(status);
        test.assert(result.status == 200);
    });

    casper.run(function() {
        test.done();
    });
});
