is there a way to find element by id or by classname

[Vivian Ho]

I'm testing a table with cells that have unique id's (dynamically generated).  Some cells are only visible when hovering.  The css or xpath for those cells are not very useful, like: '/li/button'.  But they have an id and a classname that can be easily searched.  Is there a way to do the selenium wd equivalent of getElementByClassName?  Any help is appreciated.

Per the Nightwatch API pretty much every assertion and command takes a CSS selector as the first argument. If you want to perform a particular Assertion or Command on an element by ID just use the CSS selector for the ID (i.e. "#element-id"), otherwise by class CSS selector (i.e. ".class-name").

So for short example:

browser.url("application url")

  .waitForElementVisible("#element-id", 5000)

  .assert.containsText(".class-name", "Expected Text")

  .end();

Hope that helps.

No Kerry, this is not working in nightwatch.
Class Css selector not working by (".classname")
Unable to locate element: ".col-md-6 vert-offset-bottom-1" using: css selector

Looks like you are providing two css class names ".col-md-6 vert-offset-bottom-1". Try to give one i.e ".col-md-6" or ".vert-offset-bottom-1".
