The playground allows you to easily test your extension code.

Go to the extensions page and click on Playground .

Select which type of extension you want to test and enter the code.

You will be able to select the method you want to test. Different methods have different simulation parameters. Seanime will reproduce accurate parameters to pass to your actual methods based on these simulation parameters.

Note that, under the hood, Seanime parses your code and creates real extension instances to get the output. This means that your class needs to have all methods with the accurate signatures, even if they are not implemented or used.
