Need to wait on value not being empty...

[Karl Krasnowsky]

We have a test requirements that requires that after a page loads, we replace the default values of a text field elements with another string.

Seems easy, but the problem is, this react app is dynamically rendering the text in the fields after the page loads... so while the implicit wait will wait until the actual element is found, the text is not updated yet so the routine will attempt to clear the value that is not there yet and enter the new string... after which we have a condition where the two values are concatenated.

What I believe I need is a wait for when the "value" attribute of an element is not empty (I've seen many examples of waiting until a text field has a specific value, but this can't work in this case, simply that it has a value), but I'm having a heck of a time finding an example of this. Thought it would be relatively easy to find...

This is in java.

Hi,

It would be great if you provide more details and url if possible to provide best solutions

Similar situation I have also faced in my project, 

What I have done, I have just created a magic Utility function for send keys. 

public void magicClick(By by, int count) {
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(Constants.DEFAULT_TIME_OUT));
wait.until(ExpectedConditions.visibilityOfElementLocated(by));
int loop = 0;
while (loop < count) {
wait.until(ExpectedConditions.elementToBeClickable(by)).click();
loop++;
}
}

and call this method 5 to 6 times where you are entering the data,  magicClick(firstname, 7)

Hope this make shifter will work for you as well.

Provide an url to what exactly? my not yet released web site?
I believe I was as clear as I could be... I need to wait on a text input element to be updated with text data injected by a javascript process before continuing. when the element first renders it's visible, but without initial text. The joy of a dynamic web site.

>> wait.until(ExpectedConditions.visibilityOfElementLocated(by));

Thanks, but my problem isn't that the element isn't visible, it is... the problem is the value attribute of the element is not applied yet.

Here is the documentation for ExpectedConditions in Java.  https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/support/ui/ExpectedConditions.html

If the field always ends up with a known default value when React is done, you could probably do something like

wait.until(ExpectedConditions.attributeToBe(ByLocator/WebElement, "value", "default text that shows up"));

Another option could be

wait.until(ExpectedConditions.attributeToBeNotEmpty(WebElement, "value")); , but I've not used this one personally so I don't know if it will work on the value attribute of an input.

Another possibility to consider could be using ExpectedConditions.not() with ExpectedConditions.attributeToBe(), which is likely similar to what ExpectedConditions.attributeToBeNotEmpty is doing. That would look something like this.

wait.until(ExpectedConditions.not(ExpectedConditions.attributeToBe(ByLocator/WebElement, "value", ""))); , but the handling of empty string, "", can sometimes lead to unexpected results so be careful.

Good luck!
