    new Test.Unit.Runner({ testCalculatorAdd: function() { with (this) { var calc = new Calculator(); assertEqual(4, calc.add(2, 2)); } } });
  • 3. Różne biblioteki
      • JSSpec
    describe(&quot;Calculator&quot;, function() { with(this) { it(&quot;should add numbers&quot;, function() { var calc = new Calculator(); calc.add(2, 2).should(equal(4)); }); } });
  • 4. Różne biblioteki
      • JSpec
    describe 'Calculator' it 'should add numbers' var calc = new Calculator calc.add(2, 2).should.equal 4 end end

  • 15. Blue Ridge $ rake js:shell ================================================= Rhino JavaScript Shell To exit type 'exit', 'quit', or 'quit()'. ================================================= - loaded env.js - sample DOM loaded - jQuery-1.2.6 loaded ================================================= Rhino 1.7 release 2 PRERELEASE 2008 07 28 js> $('body').append(&quot;<p>asd</p>&quot;) [object Object] js> $('p').length 1 js>
  • 16. Blue Ridge
    • Uwagi:
      • Rhino + env.js ≠ przeglądarka
      • bugi w env.js
      • Smoke.reset() nie resetuje :-)
