Selenium - element not interactable

Question

I have created a test plan using Selenium/Webdriver in JMeter and trying to run the test plan using chrome driver in headless mode, unfortunately it didn't work. Please see the logs below for more information.

Answer 1

JMeter works just fine, there is a problem with your test script itself.

You're getting ElementNotInteractableException which means that:

Thrown to indicate that although an element is present on the DOM, it is not in a state that can be interacted with.

I would recommend using Explicit Wait so your script would attempt to work with the element only when it is ready for that using i.e. ExpectedConditions.elementToBeClickable function, something like:

WDS.sampleResult.sampleStart()
WDS.browser.get('http://example.com')
var wait = new org.openqa.selenium.support.ui.WebDriverWait(WDS.browser, 10)
var conditions = org.openqa.selenium.support.ui.ExpectedConditions
wait.until(conditions.elementToBeClickable(org.openqa.selenium.By.linkText('More information...')))
WDS.sampleResult.sampleEnd()

Answer 2

WebDriverSampler: element not interactable

This error means that the element you were targeting was found but it was not interactable. Does the error log say which element it was? It could be disabled for instances like:

• Login button is disabled until a username and password is entered.

I would try putting a breakpoint and running it locally to figure out where exactly it breaks. The wait time could be the issue but it can also be something like the script entering an invalid username which causes the login button to be disabled and "not interactable".
