How can I generate custom logs using the `rebot` command in Robot Framework?

I’m running a Robot Framework test suite like this:

```bash
pybot -o output1.xml -l log1.html -r report1.html testsuite.robot

After executing, I get the default output XML, log, and report files. Suppose I rerun failed tests:

pybot --rerunfailed -o output2.xml -l log2.html -r report2.html testsuite.robot

Now I want to merge the XML files using rebot:

rebot --merge output1.xml output2.xml

By default, this generates log.html and report.html. How can I specify custom log and report names, for example:

rebot --merge output1.xml output2.xml -l Final_Log.html -r Final_Report.html


I want to generate customized logs and reports after merging the XMLs using `rebot robot framework`.

Yes! You can specify custom log and report file names when merging output XMLs with rebot. For example:

rebot --merge output1.xml output2.xml -l Final_Log.html -r Final_Report.html

This tells rebot to merge the XMLs and generate Final_Log.html and Final_Report.html instead of the default log.html and report.html. I use this whenever I rerun failed tests and want a single, consolidated report with a clear name.

You can also control the output directory in addition to the log/report names:

rebot --merge output1.xml output2.xml -o Final_Output.xml -l Final_Log.html -r Final_Report.html

This generates a custom merged output XML along with your specified log and report. I often use this approach for CI pipelines where I want consistent naming across multiple test runs.

If you prefer more readable commands, rebot supports long-form arguments too:

rebot --merge output1.xml output2.xml --log Final_Log.html --report Final_Report.html --output Final_Output.xml

This does the same thing, but makes it clear which files are logs, reports, or merged output. I like this style in team scripts—it reduces confusion when merging multiple runs.
