示例1: testStatsCalculation

import com.google.javascript.jscomp.PerformanceTracker.Stats; //導入依賴的package包/類
public void testStatsCalculation() {
  PerformanceTracker tracker =
      new PerformanceTracker(emptyExternRoot, emptyJsRoot, TracerMode.ALL, null);
  CodeChangeHandler handler = tracker.getCodeChangeHandler();

  // It's sufficient for this test to assume that a single run of any pass
  // takes some fixed amount of time, say 5ms.
  int passRuntime = 5;

  tracker.recordPassStart("noloopA", true);
  handler.reportChange();
  tracker.recordPassStop("noloopA", passRuntime);

  tracker.recordPassStart("noloopB", true);
  handler.reportChange();
  tracker.recordPassStop("noloopB", passRuntime);

  tracker.recordPassStart("loopA", false);

  tracker.recordPassStart("loopB", false);
  tracker.recordPassStop("loopB", passRuntime);

  tracker.recordPassStart("noloopB", true);
  tracker.recordPassStop("noloopB", passRuntime);

  int numRuns = tracker.getRuns();

  assertEquals(7, numRuns);
  assertEquals(tracker.getRuntime(), numRuns * passRuntime);
  assertEquals(3, tracker.getLoopRuns());
  assertEquals(4, tracker.getChanges()); /* reportChange was called 4 times */
  assertEquals(1, tracker.getLoopChanges());

  ImmutableMap<String, Stats> stats = tracker.getStats();
  Stats st = stats.get("noloopA");
  assertEquals(1, st.runs);
