It's easy to use a file as a request body.

=== ":material-language-kotlin: Kotlin"
    ```kotlin
      private val client = OkHttpClient()

      fun run() {
        val file = File("README.md")

        val request = Request.Builder()
            .url("https://api.github.com/markdown/raw")
            .post(file.asRequestBody(MEDIA_TYPE_MARKDOWN))
            .build()

func readAndMap(files []string, partNum, blockNum int) (*mappedData, error) {
	var m mappedData
	sort.Strings(files)
	m.parityData = make(map[int]map[int][]byte)
	for _, file := range files {
		meta, err := os.ReadFile(file + ".json")
		if err != nil {
			return nil, err
		}
		type erasureInfo struct {
			V2Obj *struct {
				EcDist    []int
				EcIndex   int
				EcM       int
				EcN       int

  fun explicitRemoveAppliedToDiskImmediately() {
    val editor = cache.edit("k1")!!
    editor.setString(0, "ABC")
    editor.setString(1, "B")
    editor.commit()
    val k1 = getCleanFile("k1", 0)
    assertThat(readFile(k1)).isEqualTo("ABC")
    cache.remove("k1")
    assertThat(filesystem.exists(k1)).isFalse()
  }

  @Test
  fun removePreventsActiveEditFromStoringAValue() {
    set("a", "a", "a")

        }

        @Test
        @DisplayName("Should get and set read size")
        void testReadSizeProperty() {
            testMessage.setReadSize(1024);
            // No getter for readSize, but it's used internally in decode
        }

        @Test
        @DisplayName("Should check if async")
        void testAsyncProperty() {
            assertFalse(testMessage.isAsync());
        }

### Creating commits and writing commit messages

The commit messages that accompany your code changes are an important piece of documentation. Please follow these guidelines when creating commits:

func loadMetacacheSample(t testing.TB) *metacacheReader {
	b, err := os.ReadFile("testdata/metacache.s2")
	if err != nil {
		t.Fatal(err)
	}
	return newMetacacheReader(bytes.NewReader(b))
}

func loadMetacacheSampleEntries(t testing.TB) metaCacheEntriesSorted {
	r := loadMetacacheSample(t)

            valueLines.clear();
            StringBuilder buffer = new StringBuilder();

            while (true) {
                String line = readLine();
                if (line == null) {
                    // EOF
                    return null;
                }

                if (isCommentLine(line)) {
                    commentLines.add(line);

            commentLines.clear();
            valueLines.clear();
            StringBuilder buffer = new StringBuilder();

            while (true) {
                String line = readLine();
                if (line == null) {
                    // EOF

                }

                if (isCommentLine(line)) {
                    commentLines.add(line);

operations to be executed and the obtained results that need to be tested.

The YAML tests support various operators defined in the link:/rest-api-spec/src/yamlRestTest/resources/rest-api-spec/test/README.asciidoc[rest-api-spec] and adhere to the link:/rest-api-spec/README.markdown[Elasticsearch REST API JSON specification]
In order to run the YAML tests, the relevant API specification needs
to be on the test classpath. Any gradle project that has support for REST
