Example 82 with MutableSpan

use of brave.handler.MutableSpan in project brave by openzipkin.

the class ITHttpServer method notFound.

/**
 * If http route is supported, then the span name should include it
 */
@Test
public void notFound() throws IOException {
    // we can't use get("/foo/bark") because get(path) throws assumption fail on 404

Example 83 with MutableSpan

use of brave.handler.MutableSpan in project brave by openzipkin.

the class ITHttpServer method createsChildSpan.

/**
 * This ensures thread-state is propagated from trace interceptors to user code. The endpoint
 * "/child" is expected to create an in-process span. When this works, it should be a child of the
 * "current span", in this case the span representing an incoming server request. When thread
 * state isn't managed properly, the child span will appear as a new trace.

@Test

    MutableSpan server = testSpanHandler.takeRemoteSpan(SERVER);
