CasperJS Changelog


XXXX-XX-XX, v1.0.0


Important Changes & Caveats


Reverted to emulated mouse events

For some (weird) reason, emulated mouse events are actually more accurate than native ones.

Weird, I said.


Added support for frames

Short excerpt of related tests:

casper.start('tests/site/frames.html');

casper.waitForFrame('frame1', function() {
    this.test.assertTitle('CasperJS test frames');
});

casper.withFrame('frame1', function() {
    this.test.assertTitle('CasperJS frame 1');
});


Reverted to emulated mouse events

Native mouse events didn't play well with (i)frames, because the computed element coordinates of the clicked element were erroneous.

So programmatic mouse events are reintroduced back into this corrective RC until a better solution is found.


Bugfixes & enhancements


merged #269 - Windows Batch script: fixed unsupported spaces in path and argument splitting


2012-12-10, v1.0.0-RC5

I told you there won't be an 1.0.0-RC5? I lied. Expect 1.0 stable for Christmas, probably.


Important Changes & Caveats


Casper.evaluate() signature compatibility with PhantomJS

Casper.evaluate() method signature is now compatible with PhantomJS' one, so you can now write:

casper.evaluate(function(a, b) {
    return a === "foo" && b === "bar";
}, "foo", "bar"); // true


The old way to pass arguments has been kept backward compatible in order not to break your existing scripts though:

casper.evaluate(function(a, b) {
    return a === "foo" && b === "bar";
}, {a: "foo", b: "bar"}); // true


Specification of planned tests

In order to check that every planned test has actuall been executed, a new optional planned parameter has been added to Tester.done():

casper.test.assert(true);
casper.test.assert(true);
casper.test.assert(true);
casper.test.done(4);


Will trigger a failure:

fail: 4 tests planned, 3 tests executed.


That's especially useful in case a given test script is abruptly interrupted leaving you with no obvious way to know it and an erroneous success status.

The whole CapserJS test suite has been migrated to use this new feature.


Experimental support for popups

PhantomJS 1.7 ships with support for new opened pages — aka popups. CasperJS can now wait for a popup to be opened and loaded to react accordingly using the new Casper.waitForPopup() and Casper.withPopup() methods:

casper.start('http://foo.bar/').then(function() {
    this.test.assertTitle('Main page title');
    this.clickLabel('Open me a popup');
});

// this will wait for the popup to be opened and loaded
casper.waitForPopup(/popup\.html$/, function() {
    this.test.assertEquals(this.popups.length, 1);
});

// this will set the popup DOM as the main active one only for time the
// step closure being executed
casper.withPopup(/popup\.html$/, function() {
    this.test.assertTitle('Popup title');
});

// next step will automatically revert the current page to the initial one
casper.then(function() {
    this.test.assertTitle('Main page title');
});


Casper.mouseEvent() now uses native events for most operations

Native mouse events from PhantomJS bring a far more accurate behavior.

Also, Casper.mouseEvent() will now directly trigger an error on failure instead of just logging an error event.


Bugfixes & enhancements

2012-10-23, v1.0.0-RC3


Important Changes & Caveats


the injector module is now deprecated, but kept for backward compatibility purpose.

BC BREAK: fixes #220, #237 - added a waitTimeout options, removed defaultWaitTimeout option.

BC BREAK (for the better): fixes #249 - default timeout functions don't die() anymore in tests

BC BREAK (for the better): merged #188 - Easy access to current response object;
You can now access the current response object as the first parameter of step callbacks:


require('casper').create().start('http://www.google.fr/', function(response) {
    require('utils').dump(response);
}).run();


That gives:

$ casperjs dump-headers.js
{
    "contentType": "text/html; charset=UTF-8",
    "headers": [
        {
            "name": "Date",
            "value": "Thu, 18 Oct 2012 08:17:29 GMT"
        },
        {
            "name": "Expires",
            "value": "-1"
        },
        // ... lots of other headers
    ],
    "id": 1,
    "redirectURL": null,
    "stage": "end",
    "status": 200,
    "statusText": "OK",
    "time": "2012-10-18T08:17:37.068Z",
    "url": "http://www.google.fr/"
}


To fetch a particular header by its name:

require('casper').create().start('http://www.google.fr/', function(response) {
    this.echo(response.headers.get('Date'));
}).run();


That gives:

$ casperjs dump-single-header.js
Thu, 18 Oct 2012 08:26:34 GMT


The documentation has been updated accordingly.


Bugfixes & enhancements


merged #234 - New Windows Loader written in Batch. Python is no more a requirement for using CasperJS on Windows. New installation instructions are available.

closes #230 - added ClientUtils.getElementsBound() and Casper.getElementsBound()

fixed #235 - updated Casper.evaluate() to use phantomjs >= 1.6 native one. As a consequence, the injector module is marked as deprecated.

fixed #254 - fix up one use of qsa, hit when filling forms with missing elements

fixed edge case when current document url couldn't be properly decoded


2012-10-01, v1.0.0-RC2


Important Changes & Caveats


PhantomJS 1.6 is now the minimal requirement, PhantomJS 1.7 is supported.
CasperJS continues to ship with its own implementation of CommonJS' module pattern, due to the way it has to work to offer its own executable. While the implementations are nearly the same, 100% compatibility is not guaranteed.


Bugfixes & enhancements

fixed #231 - added --pre and --post options to the casperjs test command to load test files before and after the execution of testsuite
fixed #232 - symlink resolution in the ruby version of the casperjs executable

2012-05-12, v0.6.7


fixes #107: client utils were possibly not yet being injected and available when calling Capser.base64encode() from some events
merged PR #96: make python launcher use os.execvp() instead of subprocess.Popen() (@jart):
> This patch fixes a bug where casperjs' python launcher process won't pass along kill
> signals to the phantomjs subprocess. This patch works by using an exec system call
> which causes the phantomjs subprocess to completely replace the casperjs parent
> process (while maintaining the same pid). This patch also has the added benefit of
> saving 10 megs or so of memory because the python process is discarded.
