EnableTestTracingRule

public class EnableTestTracingRule
extends LoggingBaseRule

java.lang.Object
↳	org.junit.rules.ExternalResource
	↳	android.support.test.rule.logging.LoggingBaseRule
		↳	android.support.test.rule.logging.EnableTestTracingRule

当施加到一个测试类此TestRule呼叫Trace.beginSection()测试方法执行之前。 然后Trace.endSection()在测试方法执行后调用Trace.endSection() 。 TestRule使Systrace / Atrace输出具有关于什么时间/哪些测试方法运行的离散信息（这有助于在性能测试调试期间）。

If the API level is less than 18 (Jelly Bean) this rule will do nothing since Trace isn't supported.

Usage: \@Rule public EnableTestTracingRule mEnableTestTracing = new EnableTestTracingRule();
