nickwallen opened a new pull request #1510: METRON-2254 Intermittent Test Failure in RestFunctionsIntegrationTest
URL: https://github.com/apache/metron/pull/1510
 
 
   The `RestFunctionsIntegrationTest.restGetShouldTimeoutWithSuppliedTimeout` test will intermittently fail.
   
   We use an in-memory, mock server to respond to HTTP requests made during these tests. The way that we currently test a timeout is to set the timeout extremely low (1 millisecond) and assume that the in-memory, mock server will not be able to respond fast enough.  In most cases this works, but in some cases this does not and causes CI failures.
   
   This most likely doesn't work at times because the functionality that we use to timeout just isn't granular enough to enforce a 1 millisecond timeout.  So its much more likely enforcing a timeout on the order of tens or hundreds of milliseconds.  And if the enforcement mechanism is slower than mock server, the test case will fail.
   
   Rather than doing that, there is a method that allows us to introduce a fixed delay before the mock server responds.  This should provide us with reliable pass/fail signal from these tests.
