@ParameterizedTest is used to signal that the annotated method is a parameterized test method.

@ParameterizedTest methods must specify at least one ArgumentsProvider via the @ArgumentsSource or a corresponding composed annotation. The provider is responsible for providing a Stream of Arguments that will be used to invoke the @ParameterizedTest method. The method may have additional parameters to be resolved by other ParameterResolvers at the end of the method's parameter list.

Method parameters may use @ConvertWith or a corresponding composed annotation to specify an explicit ArgumentConverter.

@ParameterizedTest may also be used as a meta-annotation in order to create a custom composed annotation that inherits the semantics of @ParameterizedTest.

@ParameterizedTest methods must not be private or static.

public abstract String name

The name pattern to be used for invocations of the parameterized test; never blank or consisting solely of whitespace.

You may use the following placeholders:

• {index}: the current invocation index (1-based)
• {arguments}: the complete, comma-separated arguments list
• {0}, {1}, etc.: an individual argument

For the latter, you may use MessageFormat patterns to customize formatting of values.
