Writing Testable Code

No Curly in lambdas

  • Discipline to write code
  • modularizing the code to smaller cohesive functions
  • not to write Lambdas that are a beast
  • make Lambda as a glue code - http://blog.agiledeveloper.com/2015/06/lambdas-are-glue-code.html
  • use the test to be able to debug the code
  • Write code using tests - Test first development

Use polymorphism rather than type checking - avoid instance of at all costs

//Exception handling is imperative stype of programming

//In function programmingm we deal with the stream of Data - data flow

hand it over to downstreams - flat type return car rental

reactive has error channel

handle the exception as error rather than exception

Mike Cohen’s Test Pyramid

  • write tests with different granularity
  • the higher you go up the pyramid, the fewer tests you should have
  • 70% unit tests, 20% service tests, 10% UI tests
