   If you would prefer that JUnit Jupiter execute all test methods on the same test

   The "per-class" mode has some additional benefits over the default "per-method" mode.
   Specifically, with the "per-class" mode it becomes possible to declare `@BeforeAll` and
  
positive.code: `ArgumentsAccessor`, JUnit Jupiter also supports the usage of custom, reusable
  _aggregators_.
  
  To use a custom aggregator simply implement the `{ArgumentsAggregator}` interface and
  register it via the `@AggregateWith` annotation on a compatible parameter in the
  `@ParameterizedTest` method. The result of the aggregation will then be provided as an
  argument for the corresponding parameter when the parameterized test is invoked. Note
  that an implementation of `ArgumentsAggregator` must be declared as either a top-level

  ==== The TempDirectory Extension
  
  The `TempDirectory` extension can be used to create and clean up a temporary directory
  for an individual test or all tests in a test class. To use it, register the extension
  and add a parameter of type `java.nio.file.Path` annotated with `@TempDir` to your test
  method, lifecycle method, or test class constructor.
  
  For example, the following test registers the extension for a single test method, creates
  and writes to a file in the temporary directory, and checks its content.
