Applications should avoid creating many connection pools as doing so
    prevents connection reuse. Each connection pool holds its own set of
    connections alive so applications that have many pools also risk exhausting
    memory!

    The best practice in OkHttp 3 is to create a single OkHttpClient instance

    // ideographic space
    assertThat(parse("http://h/\u3000").encodedPath).isEqualTo("/%E3%80%80")
  }

  @Test
  fun newBuilderResolve() {
    // Non-exhaustive tests because implementation is the same as resolve.
    val base = parse("http://host/a/b")
    assertThat(base.newBuilder("https://host2")!!.build())
      .isEqualTo(parse("https://host2/"))
