Testing nodejs apps

Testing nodejs apps

• 1.
  Test, test, test… lookingfor a great guy to test node.js applications
• 2.
  What am Ilooking for? • It should be easy! • Browser support • Integrate with CI • Born async
• 3.
  Nodeunit • Pros – Simple and easy to learn – Sandbox feature, great to test client-side code • Cons – Missing high level assertions – Do not allow groups inside groups – Force to call done() for testcases and callback() for setup/teardown every time;
• 4.
  Vows • Pros – BDD Style (clean and meaningful syntax) – Extends the node assertions – The tests could be nested or parallelized – Great output when the test fail. – Play nice with coffee script • Cons – Topic; Batches; Context can drive you crazy when begging – No built-in spies – Do not have browser support
• 5.
  Mocha • Pros – Different DSLs “interfaces” (TDD, BDD, Expect, qUnit) – Browser support – Highlight slow tests – String diff support – Async tests: You don’t need to call “done” every time like nodeunit does. – before[Each](); after[Each](); could be async as well – Play nice with coffee script – Fun reports • Cons – Do not paralyze tests (I’m not sure it’s a bad thing, cuz it can cause false positive)
• 6.
  Jasmine-node • Pros – Long time on the market – Excellent browser support (fixtures and etc) • Cons – WaitFor, although the jasmine-node brings an alternative. – It’s not maintained for the same jasmine team/pivotal
• 7.
  Buster • Pros – Hybrid, node and browser testing. – Shipped with xUnit and BDD style – jsTestDriver like to run client-side tests – It’s doesn’t comes with spies but plays nice with Sinon.JS (created by the same guy. Tks Christian J.) – Clear roadmap • Cons – Beta =/. It might brake your tests before becomes stable.
• 8.
  Misc. • Assertions – Should.js – Expect.js – Chaijs • Spies – Sinon.js • Utils – Async.js • Running client-side tests from your terminal – Envjs; Phantonjs; Jsdom – jsTestDriver
