There are 5 Validation types described below.
Text Present
Text Validation is done when this validation type is chosen, you will have to provide the Expected text value, as this is JS code, the expected value should be written in quotes.
The values can also be driven from the CSV sheet, an example in Driving Validation from CSV will show the usage and syntaxes.
Image Exists
This will validate whether the browsed image is available on the application under test
Text Present in Element
Text Present in Element will look for the text in the locator, locator follows the test designer syntax.
The Expected value is a text that should be mentioned in double-quotes since the expected value is in JS Code, Expected value can also be driven from a CSV file
Element Exists
This is a simple Element Exists on the page validation, it follows the same syntax as in the Locator field
JS Code
This option allows you to write a JavaScript code to elaborate a more structured and personalized validation
