- [Instructor] Like testing frameworks,…there are multiple options…for third party assertion libraries.…We're going to take a brief look at four assertion libraries…that work with any test framework.…We'll start with Assert, then Chai,…code, and finally should.js.…I'll discuss each library's features,…then give a code example.…Assert is Node.js's built-in test driven…development assertion library using the assert style.…It's simple, but completely functional.…
Assert includes 14 different assertions…to cover basic comparisons.…However, Assert does not support language chaining.…Assert does not have any external dependencies,…which makes sense as it's part of Node.…As an example of this TDD style…you can assert that the values actual…are equal to the expected.…Chai from chaijs.com is a behavior driven development…and test driven development assertion library.…Chai supports multiple assertion styles,…including the assert TDD style,…along with the BDD styles should and expect.…
Chai can be used with both Node.js and for browser testing.…
