录制脚本时，总会出现一些莫名其妙的错误，下面总结了一些：
1、[MsgId: MESG-26388] 错误解决方法：
Action.c(29): web_submit_form("UserLogin.action") highest severity level was "ERROR", 172503 body bytes, 19076 header bytes [MsgId: MMSG-26388]
改用基于URL的脚本录制方式，然后回放后，就一切ok了。
2、[MsgId: MERR-27979] 错误解决方法：
在LR中录制脚本时有如下问题：
Action.c(41): web_submit_form highest severity level was "ERROR", 0 body bytes, 0 header bytes [MsgId: MMSG-27178]"
3、Message Code 27979
Requested form not found
The form was not found in the page received from the server. Possible reasons: (i) The current or a previous HTML page was changed after the script was recorded. (ii) A previous request navigated to a wrong page or failed. (iii) One or more web_submit_form arguments are missing or incorrect (especially for manually coded, parameterized, or correlated functions). (iv) The server returned an unexpected page (e.g., under excessive load).
Troubleshooting
- If the current or previous HTML page was changed, look for the correct properties of the form used in the text (e.g., action), and change it in the script.
- If your snapshots and extended log are disabled, enable them and run the script again.
(i) To enable Snapshots: Select Tools > General Options > Correlation, and check the Save correlation information during replay box.
(ii) To enable Extended Log: Select Run-time Settings > General: Log, and check Enable logging, Always send messages, Extended log, Data returned by server, Advanced trace.
- Compare the record and replay snapshots for each step in the script from the beginning, and locate the first difference. If you identify a difference in the snapshots, locate the corresponding HTTP request in both the recording log and the extended log. Compare the requests and, if they are different, have the replay issue exactly the same request. This can be done, for example, by adding web_add_header (for adding missing headers or adjusting existing ones), web_remove_auto_header (for removing extra headers), and web_add_cookie (for missing cookies).
- If some correlation is missing, (e.g., the recording and replay runs have different session IDs), use the correlation tool to locate and handle such cases.
