### Question:
DSLParser { private static Map<String, String> parseQuery(final String query) { final Map<String, String> parameters = new HashMap<>(); if (query == null || query.trim().isEmpty()) { return parameters; } final byte[] bytes = query.getBytes(StandardCharsets.UTF_8); int pos = 0; int end = bytes.length; String name; String value; while (pos < end) { int nameStart = pos; int nameEnd = -1; int valueStart = -1; int valueEnd = -1; boolean parsingName = true; boolean decodeName = false; boolean decodeValue = false; boolean parameterComplete = false; do { switch (bytes[pos]) { case '=': if (parsingName) { nameEnd = pos; parsingName = false; valueStart = ++pos; } else { pos++; } break; case '&': if (parsingName) { nameEnd = pos; } else { valueEnd = pos; } parameterComplete = true; pos++; break; case '%': case '+': if (parsingName) { decodeName = true; } else { decodeValue = true; } pos++; break; default: pos++; break; } } while (!parameterComplete && pos < end); if (pos == end) { if (nameEnd == -1) { nameEnd = pos; } else if (valueStart > -1 && valueEnd == -1) { valueEnd = pos; } } if (nameEnd <= nameStart) { continue; } name = new String(bytes, nameStart, nameEnd - nameStart); if (decodeName) { name = decode(name); } if (valueStart >= 0) { value = new String(bytes, valueStart, valueEnd - valueStart); if (decodeValue) { value = decode(value); } } else { value = "true"; } parameters.put(name, value); } return parameters; }  static Step parse(final String rawUri);  }### Answer:
@Test void parseQuery() throws UnsupportedEncodingException { assertEquals(emptyMap(), DSLParser.parse("foo: assertEquals(singletonMap("a", "b"), DSLParser.parse("foo: final String url = "jdbc: assertEquals(singletonMap("configuration.url", url), DSLParser.parse("foo: assertEquals(new HashMap<String, String>() { { put("configuration.url", url); put("configuration.password", "vault:v1:something"); } }, DSLParser .parse("foo: + "&configuration.password=vault:v1:something") .getConfiguration()); }
