本文档主要描述了如何使用 test_client 和 test_server 进行测试。
在运行 test_server 之前，需要先生成证书：
cd build
keyfile=server.key
certfile=server.crt
openssl req -newkey rsa:2048 -x509 -nodes -keyout "$keyfile" -new -out "$certfile" -subj /CN=test.xquic.com运行 test_client 和 test_server：
./test_server -l d > /dev/null &
./test_client -a 127.0.0.1 -p 8443 -s 1024000 -E注意：不同的服务端之间， session ticket 、传输参数、 token 可能是不兼容的。在使用 test_client 连接到一种服务端之后，需要连接到另外一种服务端，则需要删除 test_client 本地保存的 test_session 、 tp_localhost 、 xqc_token 文件，否则可能造成连接失败。 此外，同一个服务端上的不同域名，可能配置了不同的证书。因此，如果要使用 test_client 先后以不同域名连接到同一个服务端，也需要注意本地保存的 test_session 文件可能会造成连接失败。
以下参数都可以在 tests/test_client.c 和 tests/test_server.c 的 usage() 中找到对应说明，如本文档有更新滞后的情况，请以最新代码为准。
