Selenium, Arquillian, Eclipse: trying to make test wait until the page is fully loaded

StackOverflow https://stackoverflow.com/questions/20067585

Pregunta

this is my first time posting here. It's been just a couple of days since I started to use Selenium with Arquillian to test our website... soo please be patient because I still lack a lot of knowledge...

I'm trying to make a login-test by typing in four different combination of user name and password. Three of these are not correct, the website should show an error message when these user name and password are submitted. The test should check if the error message is really shown. Please note that the error message is just a text box in the same website (not a pop-up window or something like that...)

Before entering the next user name/password combination, I would like to refresh the website first. Otherwise the test will always detect the error message from the previous entry. The problem is that the test just stops after submitting the first user name/password and refreshing the page. In JUnit I got this error message: "org.openqa.selenium.StaleElementReferenceException: "Element not found in the cache - perhaps the page has changed since it was looked up".

I am guessing that after refreshing the test should wait some seconds until the page is fully loaded..? But if I use something like "fluentWait" with "findElement(By.id("user_name"))". The test would continue running (it won't wait) because both sessions are the same website (before refresh and after refresh) and the id "user_name" is of course always there...

I would be really grateful for any help :)

Solución

Ok, few comments to your code

  • driver = new FirefoxDriver(); - you should never instantiate driver by yourself, @Drone will do that for you
  • you should split your test into 4 methods (you are testing 4 test cases, right?) and introduce method annotated with @Before which can refresh the page between tests (or call driver.get("baseUrl + "xxyy/login.html") - this will make your code be much more concise and readable
  • you can also pull out the contents of test methods and put it in some util method, most of the code is repeating inside every test so some refactoring would be nice here:)

Try it like that and see what happens:)
