getValue throws an exception always

[Zizeke]

Hello,

I'm moving to nightwatchjs from webdriversio and having huge issues with it.

browser

.url( 'http://localhost:8181/' )

.waitForElementVisible( 'body', 1000 )

.setValue( 'select#curr1', 'euro' )

.setValue( 'select#curr2', 'huf' )

.setValue( 'input#value1', '100' )

.getValue("input#value2", function(result) {

console.log( '>>>>>>>>>', result );

})

.assert.value( 'input#value2', 30200 )

.end();

The function getValue throws an exception:

error: 'An unknown server-side error occurred while processing the command.' }

Nothing on selenium-side, no warning or error.

Any idea would be much appreciated.

nightwatch is the latest, selenium is selenium-server-standalone-2.42.2.jar, node is 0.11.13, Yosemite os.

[David Linse]

Could you provide a reproducable test, maybe against _nightwatchjs.org_ ?

Yep, sure. 

This is what I used now:

module.exports = {

"test": function( browser ){

  return browser

.url( 'http://nightwatchjs.org/' )

.waitForElementVisible( 'body', 1000 )

.getValue(".sample-test", function(result) {

console.log( '>>>>>>>>>', result );

})

.end();

}

};

Querying a field from the page of nightwatchJS, running this with the following config:

{

"src_folders": [ "test/nightwatch/tests" ],

"output_folder" : "test/nightwatch/reports",

"selenium" : {

"start_process" : false,

"server_path" : "/Dev/selenium/selenium-server-standalone-2.42.2.jar",

"log_path" : false,

"host" : "127.0.0.1",

"port" : 4444

},

"test_settings" : {

"default" : {

"launch_url" : "http://localhost",

"selenium_port"  : 4444,

"selenium_host"  : "localhost",

"silent": true,

"screenshots" : {

"enabled" : true,

"path" : "test/nightwatch/reports"

},

"desiredCapabilities": {

"browserName": "firefox",

"javascriptEnabled": true,

"acceptSslCerts": true

}

}

}

}

Definitely gives me the same output.

error: 'An unknown server-side error occurred while processing the command.'

and if you run it with --verbose?

Nevermind. It seems to be an error with the selenium server. Unfortunately the only info we get from it is "An unknown server-side error occurred while processing the command". I did a quick test with selenium server 2.40 and seems to work fine, so it must be something they changed recently. I'll look into it more to see if it's something I need to change in nightwatch. Sorry for the inconvenience.

works for me.. running on OSX with --verbose options and

$ node --version #=> 0.10.26 + selenium-server-standalone-2.42.jar

gives me..

sorry it's selenium-server-standalone-2.41.jar

[Andrei Rusu]

It seems the getValue is gone from the 2.42 version. I suggest using the following work around until a proper fix will be released:

browser.getAttribute('<selector>', 'value', function(result) {
  ...
});

[Zizeke]

Thanks, that works.

BTW, version 2.41 produced the same error, but 2.40 worked.

Hi Zizeke! Would you mind expanding a bit on why you decided to switch from webdriverio to nightwatch? These two were the "finalists" in my recent investigation of which WebDriver/JS binding we should we be using. My manager actually preferred webdriverio because it supported mocha, which is the testrunner we're already using for API tests. I talked him into letting me go with nightwatch but it would be nice to have additional "factoids" from real users for supporting evidence.

Hi all,
I would like to get the balance value using nightwatch js v0.8.15, Selenium sever standalone-2.48.2.jar based on below information,

<div class="libs-meter " id="meter-balance-container" style="display: block;"> 
<span class="title" style="font-size: 0.93em;">BALANCE</span> 
<span class="value" style="font-size: 1.01em;">£100,000,000.00</span>
</div>

My code look like,

client.getValue('#meter-balance-container.libs-meter',function(result){
console.log('Balance',result.value);
});

Output look like,

 Running: Demo test nightwatch
? Expected element to be present
Balance null

Balance value is retuning as null value. Can you please any one help on this.

Kind Regards,
Hema

[Hema]

Found the solution. Just changed getText instead of getValue.

client.getText('#meter-balance-container.libs-meter',function(result){
  console.log(result.value);
 });
