OpenTracing compatible in-memory Tracer implementation. It exposes information about the recorded spans which are useful for testing.
Add this line to your application's Gemfile:
require 'opentracing_test_tracer' OpenTracing.global_tracer = OpenTracingTestTracer.build OpenTracing.start_active_span('span name') do # do something OpenTracing.start_active_span('inner span name') do # do something else end end
See opentracing-ruby for more examples.
In addition to OpenTracing compatible methods this tracer provides following methods:
#spansreturns all spans, including those in progress.
finished?informs whether the span is finished.
start_timereturns when the span was started.
end_timereturns when the span was finished, or nil if still in progress.
tagsreturns the span tags.
logsreturns the span logs.
trace_idreturns the trace ID.
span_idreturns the current span ID.
parent_idreturns the parent span ID.
