Disadvantage of using isTextPresent method and possible work around

Default Selenium class has a method called 'isTextPresent' which can be used to
verify presence of text on a page. Disadvantage of using this method is -

It checks for presence of text in entire page, hence even if text is present at
a different location test would pass and no error would be reported.

A better approach would be to find text on the basis of it's position in page.

If text which is to be validated is part of table then 'getTable' method can be
used. 'getText' method can also be used BUT element locator should be taken as
dom so that presence of text is validated at a certain position.

Ex -

Consider presence of text "Employee Number1 :*" is to validated on a page. It
can be done as following using getText method -

verifyEquals("Asserstion Failed for getText.", "Employee Number1 :*",
selenium.getText("document.getElementsByTagName('table')[0].
getElementsByTagName('tr')[0].getElementsByTagName('td')[0]"));

verifyEquals method takes three string -

1. Error message which would be displayed if objects do not match.
2. Expected String object from app.
3. Original String Object in app. (Here getText method is used which returns
string object from the specified element locator.)

getTable method can be used here if text resides in a table. This would be as
following -

verifyEquals("Assertion Failed for getTable", "Employee Number1 :*",
selenium.getTable("document.getElementsByTagName('table')[0].0.0"));

Here Cell Address syntax is - tableLocator.row.column, where row and column
start at 0

I have used verify methods here as I didn’t want test to be aborted in case
of failure but wanted these exceptions to be raised in reports. Don't forget to
call checkForVerificationErrors as the last statement of method call or better
make it part of SelTestCase class as following -

@AfterTest(alwaysRun = true, description = "This methods checks verification
errors of testmethods.")
public void checkAfterTest() throws Exception {
checkForVerificationErrors();
}

This would avoid code duplication which would be introduced if calls are made
to checkForVerificationErrors in each test method.

Where is my defect ID?

Don't you feel ecstatic when your automated tests find bug? After all tests finding bugs give us a sense of accomplishment, is not it? And this is followed by usual cycle of defect reporting, retesting and hopefully closure of defect. But at times defects are deferred to next or future releases. Which causes test method to fail for subsequent releases. And if you are dealing with a test suite having 100s of tests then it may become difficult to remember if there was a defect reported for a failing test? How do you deal with such situation. How about adding defect-id to @description tag of TestNG test. Hence it is reported on automated test report and we would know if defect exists for a failing test - How do you track defect-id of a failing test?

Return only first or last element from webelements collection

We often come across situation when there are multiple elements on a page and we probably like to exercise only a few of them using selenium webdriver. May be just first and last element. For example on a search result page we may like to click on only first and last link and not all. This is when Iterables API comes handy. (By the way I am assuming that you have already completed watching selenium training videos :)). Once we have collection of web element then we can use Iterables to get only first or last element as following - Consider that we fetch collection of element as - List< WebElement > webElements = getDriver().findElements(By. id ( "htmlID" ));   Now we can get the first web element from this collection as -  WebElement firstElement = Iterables. getFirst (webElements,  getDriver().findElement(By. id ( "defaultElement" )));   Herein second argument -   (getDriver().findElement(By. id ( "defaultElement" )))    in the me

Selenium Tutorial: Pattern Mathing using Selenium

I must confess I have never been admirer of Regular Expression but then there are times you can not escape from it, especially while working on a website which has dynamic contents appeared in static text and you want to validate it. like - "Validate that this text appears and there is 123 here and 456 here" And the test condition is 123 and 456 could be any three digits but number if digits should not be more than three. In a crude way we can at least test this - Assert.assertTrue(selenium.getText("elementLocator").contains("Validate that this text appears and there is")); but what if text goes wrong after "and there is"... what if more than 3 digits appear in text. This is where pattern matching/regular expression comes for our rescue and we can use matches method of String class to achieve same. So the assertion would be - String text = selenium.getText("elementLocator"); Assert.assertTrue(text.matches("Validate
