Examples with TraceSpan com.google.devtools.cloudtrace.v1.TraceSpan used on opensource projects

Example 6 with TraceSpan

use of com.google.devtools.cloudtrace.v1.TraceSpan in project zipkin-gcp by openzipkin.

the class TraceTranslatorTest method testMultihostServerRootSpan_noTimestamp.

@Test
public void testMultihostServerRootSpan_noTimestamp() {
    Span span1 = Span.newBuilder().kind(Kind.SERVER).traceId("1").id("1").name("/a").build();
    Span span2 = Span.newBuilder().kind(Kind.CLIENT).traceId("1").parentId("1").id("2").name("/b?client").build();
    Span span3 = Span.newBuilder().kind(Kind.SERVER).shared(true).traceId("1").parentId("1").id("2").name("/b?server").build();
    Span span4 = Span.newBuilder().traceId("1").parentId("2").id("3").name("custom-span").build();
    Collection<Trace> traces = TraceTranslator.translateSpans("test-project", Arrays.asList(span1, span2, span3, span4));
    assertEquals(1, traces.size());
    Trace trace = traces.iterator().next();
    Map<String, TraceSpan> spansByName = getSpansByName(trace);
    assertThat(spansByName).containsOnlyKeys("/a", "/b?client", "/b?server", "custom-span");
    assertDistinctSpanIds(trace);
    assertThat(spansByName.get("custom-span").getParentSpanId()).isEqualTo(spansByName.get("/b?server").getSpanId());
    assertThat(spansByName.get("/b?server").getParentSpanId()).isEqualTo(spansByName.get("/b?client").getSpanId());
    assertThat(spansByName.get("/b?client").getParentSpanId()).isEqualTo(spansByName.get("/a").getSpanId());
// Without the timestamp field, it's not possible to correctly set the root span's parentSpanId
// to 0 because we didn't have enough information to conclude that it had no parent.
