## Tips and Best Practices

To get realistic results, you should exercise care when running benchmarks. Here are a few tips:

### Do

* Ensure that the system executing your microbenchmarks has as little load as possible. Shutdown every process that can cause unnecessary
  runtime jitter. Watch the `Error` column in the benchmark results to see the run-to-run variance.

  public void testAsListEmpty() {
    assertThat(Doubles.asList(EMPTY)).isSameInstanceAs(Collections.emptyList());
  }

  /**
   * A reference implementation for {@code tryParse} that just catches the exception from {@link
   * Double#valueOf}.
   */
  private static @Nullable Double referenceTryParse(String input) {
    if (input.trim().length() < input.length()) {
      return null;
    }
    try {

    try {
      SignedBytes.checkedCast(value);
      fail("Cast to byte should have failed: " + value);
    } catch (IllegalArgumentException ex) {
      assertWithMessage("%s not found in exception text: %s", value, ex.getMessage())
          .that(ex.getMessage().contains(String.valueOf(value)))
          .isTrue();
    }
  }

  public void testCompare() {
    for (byte x : VALUES) {

                "input": '{"name": "Foo", "price": 50.5}',
            }
        ]
    }
