/**
 * {@code @TempDir} can be used to annotate a field in a test class or a
 * parameter in a lifecycle method or test method of type {@link Path} or
 * {@link File} that should be resolved into a temporary directory.
 *
 * <p>Please note that {@code @TempDir} is not supported on constructor
 * parameters. Please use field injection instead, by annotating an
 * instance field with {@code @TempDir}.
 *
 * <h3>Temporary Directory Creation</h3>
 *
 * <p>The temporary directory is only created if a field in a test class or a
 * parameter in a lifecycle method or test method is annotated with
 * {@link TempDir @TempDir}. If the field type or parameter type is neither
 * {@link Path} nor {@link File} or if the temporary directory cannot be created,
 * an {@link ExtensionConfigurationException} or a
 * {@link ParameterResolutionException} will be thrown as appropriate. In
 * addition, a {@code ParameterResolutionException} will be thrown for a
 * constructor parameter annotated with {@code @TempDir}.
 *
 * <h3>Temporary Directory Scope</h3>
 *
 * <p>The scope of the temporary directory depends on where the first
 * {@code @TempDir} annotation is encountered when executing a test class. The
 * temporary directory will be shared by all tests in a class when the
 * annotation is present on a {@code static} field or on a parameter of a
 * {@link org.junit.jupiter.api.BeforeAll @BeforeAll} method. Otherwise &mdash;
 * for example, when {@code @TempDir} is only used on instance fields or on
 * parameters in test, {@link org.junit.jupiter.api.BeforeEach @BeforeEach},
 * or {@link org.junit.jupiter.api.AfterEach @AfterEach} methods &mdash; each test
 * will use its own temporary directory.
 *
 * <h3>Temporary Directory Deletion</h3>
 *
 * <p>When the end of the scope of a temporary directory is reached, i.e. when
 * the test method or class has finished execution, JUnit will attempt to
 * recursively delete all files and directories in the temporary directory
 * and, finally, the temporary directory itself. In case deletion of a file or
 * directory fails, an {@link IOException} will be thrown that will cause the
 * test or test class to fail.
