org.ametiste.metrics.mock.MockMetricsService

All Implemented Interfaces:

org.ametiste.metrics.MetricsService

public class MockMetricsService
extends java.lang.Object
implements org.ametiste.metrics.MetricsService

Mock metric service for test needs. Provides both independence from external aggregators and herefore external calls, and ability to verify expected metrics registration. Is recommended for use in test environment.

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.MetricsService

increment

public void increment(java.lang.String targetName,
                      int incrementValue)

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

Specified by:

increment in interface org.ametiste.metrics.MetricsService

createEvent

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

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

Specified by:

createEvent in interface org.ametiste.metrics.MetricsService

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
