Github user iraghumitra commented on the issue: https://github.com/apache/metron/pull/857 @merrimanr - I removed the node version check in the ui code - The browser.sleep is used in following areas - When we are using methods like waitForText, few times I see the test fails saying that that it got the text we were waiting to change which doesn't make sense. So, in this case, i am just yielding the main thread with a sleep of 500 milliseconds. - Create/Add meta-alert, these calls takes few seconds at times. - When we use animation to slide in the details pane, we don't have a class that gets added/removed for this so it makes it difficult for us to know when the pane is loaded. We can add/remove a class for animation by moving the slider to a component or directive. This might be out of scope for current PR. - Refactored tests for Facets - Looks like the meta alert creation failed can you attach the stack trace it might give me additional info to debug.
