```
@JsonFileSource is an ArgumentsSource that loads JSON from a file, parses it, and passes it as arguments to a parametrized test.
This annotation can be used on a method parameter, to make it usable with CartesianTest. If used with ParameterizedTest, the annotation has to be on the method itself as any other ArgumentsSource.

Note that this extension requires a JSON parser to be available at run time, which may include adding it to the module graph with --add-modules. For details on that as well as how to use this extension, see the documentation on JSON tests.

Since:

1.7.0
