What is your case actually

  1. Do you want to trigger item click event programmatically for a test case?

  2. Do you want to observe item click event (which is simply done by adding grid.addItemClickListener(…) )

The recommended way to do 1. is to use [TestBench]
(https://vaadin.com/testbench) product. It includes Element wrappers for the stock Vaadin components for easier manipulation. For example clicking first row in Grid in a test case would be something like this

GridElement grid = (GridElement) myView.findElement(By.name("my-grid"));
Iterable<GridRowElement> rows = grid.getRows();
rows.iterator().next().click();
