You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: testWavefrontObj.m
    path of file: ./repos/ott/tests/shapes
    
    the code of the file until where you have to start completion: function tests = wavefrontobj
  tests = functiontests(localfunctions);
end

function setupOnce(testCase)
  addpath('../../');
end

function testLoad(testCase)

  fn = tempname();

  % Generate a cube and write it to a file
  cube = ott.shapes.Cube(1.0);
  cube.writeWavefrontObj(fn);

  % Load the shape
  shape = ot
    
function setupOnce(testCase)
  addpath('../../');
end

function testLoad(testCase)

  fn = tempname();

  % Generate a cube and write it to a file
  cube = ott.shapes.Cube(1.0);
  cube.writeWavefrontObj(fn);

  % Load the shape
  shape = ott.shapes.WavefrontObj(fn);

  import matlab.unittest.constraints.IsEqualTo;
  import matlab.unittest.constraints.RelativeTolerance;
  tol = 1.0e-3;

  testCase.verifyThat(shape.maxRadius, IsEqualTo(cube.maxRadius, ...
      'Within', RelativeTolerance(tol)), ...
      'Incorrect radius after writing/loading OBJ file');

  testCase.verifyThat(shape.volume, IsEqualTo(cube.volume, ...
      'Within', RelativeTolerance(tol)), ...
      'Incorrect volume after writing/loading OBJ file');

  delete(fn);
