I am trying to submit an input(type= button).But I am unable to update the value. Any help is appreciated. I have attached the testcase below for your reference.
You could try substituting .click() with .send_keys("\n"), which is equivalent to "Pressing enter while focusing on an element".
.click()
send_keys("\n")
So this:
driver.find_element_by_link_text('PurchaseOrder').click()
would become this:
driver.find_element_by_link_text('PurchaseOrder').send_keys("\n")
