Good bug reports include a failing test! Writing a test helps you to isolate and describe the problem, and it helps us to fix it fast. Bug reports without a failing test or reproduction steps are likely to be closed.

Here’s an example test to get you started.

    val response =
      response("https://example.com/", s) {
        header("Content-Encoding", "deflate")
      }

    val decompressed = zstdInterceptor.decompress(response)
    assertThat(decompressed.header("Content-Encoding")).isEqualTo("deflate")

    val responseString = decompressed.body.string()
    assertThat(responseString).isEqualTo("hello unknown algorithm world")
  }

    assertThat(recorded.headers["Accept"]).isEqualTo("text/plain")
    assertThat(
      recorded.headers["Accept-Encoding"]?.split(", ").orEmpty(),
    ).containsExactlyInAnyOrder(
      "gzip",
      "x-gzip",
      "deflate",
    )
    assertThat(recorded.headers["User-Agent"]!!).startsWith("Apache-HttpClient/")
  }
