HtmlUnit won't change TextArea's text - java

I have written a code to connect to this webpage: compilerjava.net
1) I found the text-area field within that page which accepts the code to compile.
2) I have found the button that compiles the code.
3) I have found the text-area which returns the result of the code.
The issue is, when I call textarea.setText( "something"), it (I think) doesn't actually change the code in the webpage. So when I click on the compile button, it compiles the default code within that page and returns the output of that default code.
I have tried to set focus to textarea, you can see all of those down below.
I called;
1) textArea.focus();
2) textArea.click();
3) I tried using textArea.setAttribute( "name", "code");
I have searched the internet and found various stackoverflow questions close to this problem, neither of them solved my issue and it just seems to work for everyone when they say textArea.setText().
Another interesting fact I should share with you is,
If I call textArea.setText( "...") and then I say;
HtmlTextArea textArea1 = form.getTextAreaByName( "code");
If I call textArea1.getText(), the value of this text will be "...". This should imply that I have actually managed to change the value of the text-area, but when I compile, it compiles the default text in the text-area and not the text that I have set it to.
Any help with this?
P.S: The reason why I put the result of the compilation on a while loop is related to network connection issues. If you try to run this code it might not work on your first try. Also note that the run-time is around 15 seconds, because it gives thousands of warnings which I blocked to print to console.
P.S2: I also looked at this page and none of these worked;
http://www.programcreek.com/java-api-examples/index.php?api=com.gargoylesoftware.htmlunit.html.HtmlTextArea
public class Test {
public static void main(String[] args) {
try {
// Prevents the program to print thousands of warning codes.
java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(java.util.logging.Level.OFF);
java.util.logging.Logger.getLogger("org.apache.http").setLevel(java.util.logging.Level.OFF);
// Initializes the web client and yet again stops some warning codes.
WebClient webClient = new WebClient( BrowserVersion.CHROME);
webClient.getOptions().setThrowExceptionOnFailingStatusCode( false);
webClient.getOptions().setThrowExceptionOnScriptError( false);
webClient.getOptions().setJavaScriptEnabled( true);
webClient.getOptions().setCssEnabled( true);
// Gets the html page, which is the online compiler I'm using.
HtmlPage page = webClient.getPage("https://www.compilejava.net/");
// Succesfully finds the form which has the required buttons etc.
List<HtmlForm> forms = page.getForms();
HtmlForm form = forms.get( 0);
// Finds the textarea which will hold the code.
HtmlTextArea textArea = form.getTextAreaByName( "code");
// Finds the textarea which will hold the result of the compilation.
HtmlTextArea resultArea = page.getHtmlElementById( "execsout");
// Finds the compile button.
HtmlButtonInput button = form.getInputByName( "compile");
textArea.click();
textArea.focus();
// Simple code to run.
textArea.setDefaultValue( "public class HelloWorld\n" +
"{\n" +
" // arguments are passed using the text field below this editor\n" +
" public static void main(String[] args)\n" +
" {\n" +
" System.out.print( \"Hello\");\n" +
" }\n" +
"}");
System.out.println( textArea.getText());
// Compiles.
button.click();
// Result of the compilation.
String str = resultArea.getText();
while ( resultArea.getText() == null || resultArea.getText().substring(0, 3).equals( "exe")) {
System.out.print( resultArea.getText());
}
System.out.println();
System.out.println( resultArea.getText());
} catch ( Exception e) {
e.printStackTrace();
}
}
}

a little patience helps here
// Result of the compilation.
while (resultArea.getText() == null || resultArea.getText().startsWith("exe")) {
System.out.println(resultArea.getText());
Thread.sleep(500);
}
System.out.println();
System.out.println(resultArea.getText());

Selenium replace value for the input field with sendKeys() method

I have an unexpected issue with the sendKeys() method:
A long time before it all worked fine, but unexpectedly the (certain(!)) values are replaced when the code tries to set data into the input field:
For example, if I set value USER_NAME into the field, value replaced with /tmp/7d7b7...../upload123...file/USER_NAME. As we can see - some path was added into the USER_NAME value.
I added logs to the method and we can see a moment when the value was replaced:
clearInputFld(inputFld);
Log.info("INSIDE clearAndTypeIntoInputField() ---------> value after clearing: " + inputElement.getAttribute("value"));
Log.info("INSIDE clearAndTypeIntoInputField() ---------> value to set: " + value);
inputElement.sendKeys(value);
Log.info("INSIDE clearAndTypeIntoInputField() ---------> value after set: " + inputElement.getAttribute("value"));
Output:
INSIDE clearAndTypeIntoInputField() ---------> value after clearing:
INSIDE clearAndTypeIntoInputField() ---------> value to set: USER_NAME
INSIDE clearAndTypeIntoInputField() ---------> value after set: /tmp/7d7b7...../upload123...file/USER_NAME
So we can be sure - value sets exactly at the moment when value sets into the field.
Important to know, and conclusions:
Not all users replaced - Only several certain users! So I suppose a part of users is cached. But I do not understand the process with which this happens, why this happens, and where these users might be cached.
I also restarted the docker, so it seems the problem is not in the automatic side.
Is it possible that this issue occurs via the backend or UI part?
It looks like there is a script running on the page that changes the input you type, as this is a password field.
What I suggest is that you use the Robot object to mimic keyboard strokes.
First click on the text field using Selenium, then launch the Robot code (use package Java.awt):
Robot robot = null;
try {
robot = new Robot();
for (char c : textToType.toCharArray()) {
int keyCode = KeyEvent.getExtendedKeyCodeForChar(c);
if (KeyEvent.CHAR_UNDEFINED == keyCode) {
logger.error("Key code not found for character '" + c + "'");
} else {
try {
robot.keyPress(keyCode);
robot.delay(10);
robot.keyRelease(keyCode);
robot.delay(10);
} catch (Exception e) {
if (c == '_') {
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_MINUS);
robot.keyRelease(KeyEvent.VK_MINUS);
robot.keyRelease(KeyEvent.VK_SHIFT);
}
if (c == ':') {
robot.keyPress(KeyEvent.VK_SHIFT);
robot.keyPress(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SEMICOLON);
robot.keyRelease(KeyEvent.VK_SHIFT);
}
}
}
}
robot.keyPress(KeyEvent.VK_ENTER);
} catch (Exception ex) {
logger.error(ex.getMessage());
}
According to Logs, I think there is something come with the value.
Suggest trying :
Get the changed text, do some operation, fill it back
string[] temp;
temp = (inputElement.Text).Split('/');
inputElement.Sendkeys(temp(temp.Length - 1));

how to make my validator conditional for my checkbox control

I have a validator defined for my checkbox control:
<xp:checkBox uncheckedValue="false"
checkedValue="true" readonly="#{!matterBean.matter.editable}"
id="cbKCSupport" style="width:100%"
value="#{matterBean.matter.creatorKCSupport}"
validator="#{matterValidators.valCreatorKCSupport}">
</xp:checkBox>
the method is nothing fancy, I just check the value true or false of the checkbox:
public void valCreatorKCSupport(FacesContext facesContext, UIComponent component, Object value) {
utils.printToConsole(this.getClass().getSimpleName().toString() + " - valCreatorKCSupport(...), value = " + value.toString());
String msg = null;
if (value.toString().equals("false")){
msg = matterProp.getProperty("gen_KCSupport");
FacesMessage message = new FacesMessage(msg);
throw new ValidatorException(message);
}
}
I notice that this validation blocks the behaviour of other components e.g. the opening of dialog boxes.
For other controls I have a similar approach where the required property is based upon which component (buttons) have initiated the call to the server:
<xp:this.required><![CDATA[#{javascript:return ( submittedBy('btnSendToCommitee') || submittedBy('btnForCompletion') )}]]></xp:this.required>
I tried to set up a similar approach for my checkbox:
but then I get presented an error message:
Error while executing JavaScript action expression
Script interpreter error, line=2, col=33: Error calling method 'valCreatorKCSupport(com.ibm.xsp.domino.context.DominoFacesContext, com.ibm.xsp.component.xp.XspInputCheckbox, string)' on java class 'se.sebank.kkom.test.MatterValidators'
Message (text with text from matterProp.getProperty("gen_KCSupport"))
Anyone a suggestion how I should apply some conditional statement to my validator?

To 'if' or not to 'if'

I have written a code and I can't explain why is it not behaving the way it should. I know this sounds silly but it is not.
boolean verify = EDV.verifySignature(signature, cipherText,
SERVER_PUBLIC_KEY);
out.println("Validity " + verify);
if (verify) {
// //message is authentic
String decryptedMessage = EDV.decrypt(cipherText,
SERVER_PRIVATE_KEY);
out.println("Message : " + decryptedMessage);
}else
{
out.println("Signature did not match");
}
This is a simple code that verifies signature and then decrypts the message if the signature is valid(verify is true)
The output of this code is this :
Validity false
Signature did not match
The message decrypts just fine.
The problem is that the signature should verify (I have checked the signature, cipherText, and key over n times). Here's the kick.
The almost same code
boolean verify = EDV.verifySignature(signature, cipherText,
SERVER_PUBLIC_KEY);
out.println("Validity " + verify);
// if (verify) {
// //message is authentic
String decryptedMessage = EDV.decrypt(cipherText,
SERVER_PRIVATE_KEY);
out.println("Message : " + decryptedMessage);
// }else
// {
// out.println("Signature did not match");
// }
and Voila!, output is as I wanted it to be and as it should be.
Validity true
Message : This is a sample Text
And, the first code works just fine on Eclipse, but running it on JAVA servlet is the only time I get this.
Also, the first time I run the code#2 it gives false but after that it gives true.
I can't seem to explain the reason.
LINKS
Code#1
Code#2(Run this code, it gives false validity refresh it and it turns true)
Something's not initialising properly in the code just before the sample you gave. Try adding some test println statements for the signature, cipherText and SERVER_PUBLIC_KEY parameters.
Also, check the initialisation of EDV.verifySignature.

WebDriver is unable to perform click on an input element having onclick=function1() as an attribute

I am using Web driver 2.31 with Java. It seems the web driver is unable to perform click action on an input element having onclick() attribute.
The input element I need to perform click action on is having the following attributes - id (which is a random generated number), class, type=button, onclick, onmouseout, onmouseover, title and value.
I'm able to fetch the values of title and value attributes which means that the web driver is able to recognize the input element but is not able to perform click action on it.
I have tried with the following:
webdriver.findElement(By.xpath("xpath for the input")).click()
webdriver.findElement(By.xpath("xpath for the input")).sendKeys(Keys.ENTER);
new Actions(webdriver).moveToElement(webdriver.findElement(By.xpath("xpath for the input"))).click().perform();
None of the above options are working.
Do you get any exceptions from element.click()? It it enabled and visible? One of the problems we had was that WebDriver didn't handle position:static elements correctly, so during playback it would cover the button (and you won't see it on screenshot) and it would throw exception "Element is not clickable at point".
We had similar problem with element and had following code that did work sometimes (but also not 100% of times):
element.click();
if("button".equals(tagName)) {
if(element.isEnabled() && element.isDisplayed())
element.sendKeys(Keys.ENTER);
}
But the problem disappeared itself after upgrading WebDriver and we removed sendKeys(ENTER), also it was working fine in 2.29.0.
I faced exactly same problem in my project. The issue was not to locate the element but the onClick() event was not firing.
Then i found out that something else was there which stopped from the event to fire. I had used java script to enable the date picker box & did this,
((JavascriptExecutor)driver).executeScript ("document.getElementById('txtOriginDate').removeAttribute('readonly',0);");
WebElement originDateBox= driver.findElement(By.xpath(prop.getProperty("originDateBox")));
originDateBox.clear();
originDateBox.sendKeys("9-Dec-2014"); //Enter date
Developer designed this in such a way that if you don't use date picker to select date, a specific variable was not set. Which eventually made the **onclick event not to fire.
The date picker code was something like this,
var jsoncustdate = "";
var jsonorigindate = "";
function onSelectCalender( StrDt, obj )
{
if ( !varReadonly ) {
if ( $( "#txtCustDescisionDate" ).attr( "IsDisable" ) == "FALSE" )
{
if ( obj.id == "txtCustDescisionDate" )
{
custobjDt = new Date( obj.selectedYear, obj.selectedMonth,obj.selectedDay, 0, 0, 0, 0 );
jsoncustdate = custobjDt.getTime();
jsoncustdate = "\/Date(" + jsoncustdate + ")\/";
DisabledBtnStage();
// $("#txtFromDate").datepicker("option", "maxDate", objDt);
}
if ( obj.id == "txtOriginDate" )
{
var objDt = new Date( obj.selectedYear, obj.selectedMonth,obj.selectedDay,0, 0,0,0 );
jsonorigindate = objDt.getTime();
jsonorigindate = "\/Date(" + jsonorigindate + ")\/";
DisabledBtnStage();
// $("#txtToDate").datepicker("option", "minDate", objDt);
}
}
elogCommon.CheckMandatory();
}
}
I finally used date picker in normal way & the event fired smoothly.
I hope this answer will help . .cheers !!!

How can I consistently remove the default text from an input element with Selenium?

I'm trying to use Selenium WebDriver to input text to a GWT input element that has default text, "Enter User ID". Here are a few ways I've tried to get this to work:
searchField.click();
if(!searchField.getAttribute("value").isEmpty()) {
// clear field, if not already empty
searchField.clear();
}
if(!searchField.getAttribute("value").isEmpty()) {
// if it still didn't clear, click away and click back
externalLinksHeader.click();
searchField.click();
}
searchField.sendKeys(username);
The strange thing is the above this only works some of the time. Sometimes, it ends up searching for "Enter User IDus", basically beginning to type "username" after the default text -- and not even finishing that.
Any other better, more reliable ways to clear out default text from a GWT element?
Edited to add: The HTML of the input element. Unfortunately, there's not much to see, thanks to the JS/GWT hotness. Here's the field when it's unselected:
<input type="text" class="gwt-TextBox empty" maxlength="40">
After I've clicked it and given it focus manually, the default text and the "empty" class are removed.
The JS to setDefaultText() gets called both onBlur() and onChange() if the change results in an empty text field. Guess that's why the searchField.clear() isn't helping.
I've also stepped through this method in debug mode, and in that case, it never works. When run normally, it works the majority of the time. I can't say why, though.
Okay, the script obviously kicks in when the clear() method clears the input and leaves it empty. The solutions it came up with are given below.
The naïve one, presses Backspace 10 times:
String b = Keys.BACK_SPACE.toString();
searchField.sendKeys(b+b+b+b+b+b+b+b+b+b + username);
(StringUtils.repeat() from Apache Commons Lang or Google Guava's Strings.repeat() may come in handy)
The nicer one using Ctrl+A, Delete:
String del = Keys.chord(Keys.CONTROL, "a") + Keys.DELETE;
searchField.sendKeys(del + username);
Deleting the content of the input via JavaScript:
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("arguments[0].value = '';", searchField);
searchField.sendKeys(username);
Setting the value of the input via JavaScript altogether:
JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("arguments[0].value = '" + username + "';", searchField);
Note that javascript might not always work, as shown here: Why can't I clear an input field with javascript?
For what it is worth I'm have a very similar issue. WebDriver 2.28.0 and FireFox 18.0.1
I'm also using GWT but can reproduce it with simple HTML/JS:
<html>
<body>
<div>
<h3>Box one</h3>
<input id="boxOne" type="text" onfocus="if (this.value == 'foo') this.value = '';" onblur="if (this.value == '') this.value = 'foo';"/>
</div>
<div>
<h3>Box two</h3>
<input id="boxTwo" type="text" />
</div>
</body>
</html>
This test fails most of the time:
#Test
public void testTextFocusBlurDirect() throws Exception {
FirefoxDriver driver = new FirefoxDriver();
driver.navigate().to(getClass().getResource("/TestTextFocusBlur.html"));
for (int i = 0; i < 200; i++) {
String magic = "test" + System.currentTimeMillis();
driver.findElementById("boxOne").clear();
Thread.sleep(100);
driver.findElementById("boxOne").sendKeys(magic);
Thread.sleep(100);
driver.findElementById("boxTwo").clear();
Thread.sleep(100);
driver.findElementById("boxTwo").sendKeys("" + i);
Thread.sleep(100);
assertEquals(magic, driver.findElementById("boxOne").getAttribute("value"));
}
driver.quit();
}
It could just be the OS taking focus away from the browser in a way WebDriver can't control. We don't seem to get this issue on the CI server to maybe that is the case.
I cannot add a comment yet, so I am putting it as an answer here. I want to inform you that if you want to use only javascript to clear and/or edit an input text field, then the javascript approach given by #slanec will not work. Here is an example: Why can't I clear an input field with javascript?
In case you use c# then solution would be :
// provide some text
webElement.SendKeys("aa");
// this is how you use this in C# , VS
String b = Keys.Backspace.ToString();
// then provide back space few times
webElement.SendKeys(b + b + b + b + b + b + b + b + b + b);
