java.lang.Object

org.ametiste.metrics.mock.aggregator.MockMetricsAggregator

All Implemented Interfaces:

org.ametiste.metrics.MetricsAggregator

public class MockMetricsAggregator
extends java.lang.Object
implements org.ametiste.metrics.MetricsAggregator

Mock metrics aggregator for test needs. Provides independence from external calls, and ability to verify expected metrics registration. Is recommended for use in test environment when MockService cant be applied but list of aggregators can be replaced instead

Since:

0.1.0

Method Detail

gauge

public void gauge(java.lang.String metricId,
                  int gaugeValue)

If this method is used after verify chain started, IllegalArgumentException is thrown

Specified by:

gauge in interface org.ametiste.metrics.MetricsAggregator

event

public void event(java.lang.String metricId,
                  int eventValue)

If this method is used after verify chain started, IllegalArgumentException is thrown

Specified by:

event in interface org.ametiste.metrics.MetricsAggregator

increment

public void increment(java.lang.String metricId,
                      int inc)

If this method is used after verify chain started, IllegalArgumentException is thrown

Specified by:

increment in interface org.ametiste.metrics.MetricsAggregator

verify

public MockMetricsVerifier verify(java.lang.String name)

Starts chain of verify calls. After verify is started, no further service call can be made. If mock is used as service for registration after verify, IllegalArgumentException is thrown

Parameters:

name - metric name to verify

Returns:

verify chain for checking specific metrics registration

resetData

public void resetData()

Resets verified data and starts metrics gathering. Should be called before or after test methods, between new metrics sets are gathered
