For example, whenever you send an HTTP POST request from the front end to a Node.js toBeDefined(); }); }); We will add more tests to make this fully cover all the methods defined within the ProductService. Writing a test for the ‘create’ and ‘get’ products methods. and wrote the tests for its business logic. Conclusion.

Today there was an interesting discussion between Kent Beck , Martin Fowler , and David Heinemeier Hansson on the nature and use of Test-Driven Development (TDD), where one writes tests first and then writes code. It’s possible to minimize this point and say it’s only relevant to debugging or testing.

Test-Driven Development. Technically, you can refactor at any time, but unless your IDE has provably-safe refactorings, it’s best to do it when you have a good suite of tests that are all passing.

Continuous Integration. Finally, continuous integration will prevent painful merge conflicts and keep everyone’s code in sync. For example, when making changes to a service, don’t say, “We need to change SuperMailClient. Test-Driven Development. Test-Driven Development.

Testing and Continuous Integration. In JavaScript, you can get around this with an immutability library; for example, Immutable.js , Lodash , or Ramda. For example, say that the return type of a function should be a prime number. In this example, we create a definition that is equal to an unevaluated function call.
