### Question:
ManagedResourceProvider implements ResourceProvider { @Override public File provideFile( Bundle bundle, String relativePath ) { File file = getAbsoluteFile( bundle, relativePath ); return validateFile( file ); }  void setBundleContext( BundleContext bundleContext ); void init(); @Override File getManagedResourceFolder(); @Override File provideFolder( Bundle bundle, String relativePath ); @Override File provideFolder( String bundleName, String relativePath ); @Override File provideFile( Bundle bundle, String relativePath ); @Override File provideFile( String bundleName, String relativePath ); static String MANAGED_RESOURCES_DIR; }### Answer:
@Test public void provideFileTest() { Bundle nullBundle = null; assertNull( resourceProvider.provideFile( nullBundle, null ) ); File providedFile = resourceProvider.provideFile( bundle, Paths.get( relativePath, fileName ).toString() ); assertTrue( providedFile.getAbsolutePath().contains( expectedRelativePath ) ); providedFile = resourceProvider.provideFile( bundleName, Paths.get( relativePath, fileName ).toString() ); assertTrue( providedFile.getAbsolutePath().contains( expectedRelativePath ) ); }
