Introduction to Unit Testing

Unit testing verifies function behavior across edge cases, such as numbers, strings, booleans, and objects, and improves maintainability by catching regressions early.

Learn test driven development by writing unit tests before code, drive implementation with tests, handle edge cases, and gain a solid, efficient codebase with integrated tests.

Create a basic testing framework and an assert function to compare inputs and outputs, then write specs to test a pluralize function with various edge cases.

Integrate jasmine into the workflow to drive test-driven development, using a spec runner and jasmine framework to define pluralize tests with describe, it, and expect.

Define unit testing as testing the smallest piece of code in isolation, verifying outputs with automated inputs and expectations, and exploring test coverage and frameworks like Jasmine.

Adopt behavior-driven expect semantics with describe blocks to define code behavior, embrace duplication for isolation, and run unit suites on client or server with Mocha or Jasmine.

Explore how unit testing with Jasmine supports behavior-driven development, descriptive test outputs, modular code, set up and tear down, and continuous integration in development workflows.

Discover test driven development as an approach to building software, using the red green refactor cycle: write a failing unit test, make it pass, then refactor.
