TestPropagator (MicroProfile Telemetry Tracing TCK)

java.lang.Object

org.eclipse.microprofile.telemetry.tracing.tck.rest.TestPropagator

All Implemented Interfaces:: io.opentelemetry.context.propagation.TextMapPropagator

public class TestPropagator extends Object implements io.opentelemetry.context.propagation.TextMapPropagator

A basic propagator for span context and baggage

Span information is passed in the TEST-SPAN key with format traceId;spanId;flags;statekey1=value,statekey2=value

Baggage information is passed in the TEST-BAGGAGE key with format key,value,metadata;key2,value,metadata;key3,value,metadata;...

All individual values are urlencoded to make parsing easy (don't have to worry about values containing separator characters)
