3. An extra 500 millisecods in search page generation time dropped traffic by 20%. Every 100 millisecods of latency costs 1% in sales.
4. Teststack Unit Tests class  ProcessorTest  extends  UnitTestCase  {      /**  @test  */    public  func0on  process()  {      ...    }  }   Functional Tests class  ProcessorTest  extends  Func<onalTestCase  {      /**  @test  */    public  func0on  process()  {      ...    }  }   Acceptance Tests Feature:      In  order  to  sell  products      as  a  store  employee      I  want  to  use  the  sales  app     ....   Performance Tests jMeter??
5. jMeter
6. •  Written in Scala •  NonBlocking IO / Asynchronous –  Less Resourcen / better performance then jMeter •  Testcases written in Scala DSL gatling.io   Gatling
