Florian Barca commented on AMBARI-9612:
---------------------------------------

Investigated the test requirements. As it turns out, the chart class 
ChartLinearTimeView has tests available already (see 
ambari-web/test/views/common/chart/linear_time_test.js), and the LogFlushStats 
view uses this class directly, without modifying its behavior. The patch merely 
fixes the data source. Hence, no unit tests are really needed.
