After a first debug run, open your scenario file in any text editor and be sure an external "ex" node exists on top of file.

Originally the HAR format has only "log" root node and Optacat tool extends it for some additional features automatically

You can use title of scenario, author's name, user-agent etc.

Also, the Optacat tool uses dictionaries for generating different request parameters.

For example. using dictionary "towns": {"values": ["Denver", "Paris", "London"]} in parameter's of some request possible to use @towns. The string @towns will replaced by random value of the "towns" dictionary

The optacat tool has pre and post additional features intro&outro what can be used before and after whole test (not the scenario). For example the feature can be used for adding and removing test data in database or checking an url. For this purpose you can use external Lua scripts. And no need to install Lua additionally.
