### 3.2 Use OpenSSL to Generate a Certificate

Use one of the following methods to generate a certificate using `openssl`:

Being able to use asynchronous functions in your tests could be useful, for example, when you're querying your database asynchronously. Imagine you want to test sending requests to your FastAPI application and then verify that your backend successfully wrote the correct data in the database, while using an async database library.

    Writer writer = sink.openStream();
    try {
      writer.write(data);
    } finally {
      writer.close();
    }

    assertContainsExpectedString();
  }

  public void testOpenBufferedStream() throws IOException {
    Writer writer = sink.openBufferedStream();
    try {
      writer.write(data);
    } finally {
      writer.close();
    }

    assertContainsExpectedString();

     *
     * @param b the byte array containing the data to write
     * @param off the start offset in the data
     * @param len the number of bytes to write
     * @param flags write operation flags
     * @throws IOException if an I/O error occurs
     */
    public void writeDirect(final byte[] b, int off, int len, final int flags) throws IOException {
        if (len <= 0) {
            return;
