What are Locators in selenium

Locators  in selenium


Selenium uses different types of locators to identify the UI elements on the page.

The following is the list of locators based on the priority and recommendations to use:

1. ID
2. Name
3. Link
4. DOM
5. XPath
6. CSS
7. UI-element

i.e. You have to follow the below steps while finding the Locator for the selected UI element:
  1. First we've to find out if there is any locator which can locate the UI element by ID else you have to go to the next step
  2. Find out if there is any locator which can locate the UI element by Name else you have to go to the next step
  3. Find out if there is any locator which can locate the UI element by Link else you have to go to the next step
  4. Find out if there is any locator which can locate the UI element by DOM else you have to go to the next step
  5. Find out if there is any locator which can locate the UI element by XPath else you have to go to the next step
  6. Find out if there is any locator which can locate the UI element by CSS else you have to go to the next step
  7. Find out if there is any locator which can locate the UI element by UI-element 

Why there are different types of locators instead of having only one kind of locator to identify the UI elements ?

While building the application code, it is seen as a good practice to make sure that every element you need to interact with has an ID attribute and a Name attribute. Unfortunately, this best practice is difficult to implement for the UI elements which dynamically change. This is the reason for having different types of locators instead of having only the ID locator to identify the elements.

Verify Specific Position of an Element

By -
Verify Specific Position of an Element Selenium IDE indicates the position of an element by measuring (in pixels) how far it is from the left or top edge of the browser window. ·          verifyElementPositionLeft   - verifies if the specified number of pixels match the distance of the element from the left edge of the page. This will return FALSE if the value specified does not match the distance from the left edge. ·          verifyElementPositionTop   - verifies if the specified number of pixels match the distance of the element from the top edge of the page. This will return FALSE if the value specified does not match the distance from the top edge.

Read it out for TESTNG before going for an iterview

How to run a group of test cases using TestNG? TestNG allows you to perform sophisticated groupings of test methods. Not only can you declare that methods belong to groups, but you can also specify groups that contain other groups. Then TestNG can be invoked and asked to include a certain set of groups (or regular expressions) while excluding another set.  This gives you maximum flexibility in how you partition your tests and doesn’t require you to recompile anything if you want to run two different sets of tests back to back. Groups are specified in your testng.xml file and can be found either under the <test> or <suite> tag. Groups specified in the <suite> tag apply to all the <test> tags underneath. @Test (groups = { "smokeTest", "functionalTest" }) public void loginTest(){ System.out.println("Logged in successfully"); }   How to create Group of Groups in TestNG? Groups can also inc...
