    String expectedJson = new String(Files.readAllBytes(jsonFile), StandardCharsets.UTF_8);
    // Translates the image to the manifest and writes the JSON string.
    JsonTemplate containerConfiguration = imageToJsonTranslator.getContainerConfiguration();
    BlobDescriptor blobDescriptor = Digests.computeDigest(containerConfiguration);
    T manifestTemplate = imageToJsonTranslator.getManifestTemplate(manifestTemplateClass, blobDescriptor);
