我正在使用Tsung测试Tigase。
我的第一个测试脚本只是在Tigase服务器上注册用户。但是我有一个奇怪的问题是Tigase复制了一些用户ID的注册请求。
查看下面的tsung.dump文件。
用户43-tsung-user-2的注册请求重复两次。第一次成功，第二次Tigase返回冲突错误409，意味着用户已经注册。

我的测试需要30秒，用户间隔10秒。因此，应在数据库中创建3个用户。测试结束后，我只能看到2个用户，这也是tsung.dump所说的。
为什么tsung会重复请求某些用户？无论负载如何，Tsung的行为都相似。如果我提高负载数量，我将收到类似的行为。大多数情况下，成功注册用户的数量大约是tsung生成用户数的一半。
以下是我的tsung.xml

答案 0 :(得分：1)
Tsung随机播放场景，并将重用一些用户ID。这意味着每次选择用户播放场景时，如果这是Tsung第二次使用用户ID，则存在冲突风险。
除非您希望专门加载测试客户端注册，否则我建议您直接在Tigase中预先创建用户库。这样，您就可以从您的场景中删除注册部分，避免注册冲突。
