Assertions

An assertion is the heart of a test. It states a fact that must be true. If it is, the test continues. If not, busted records a failure with a helpful message.

busted uses the luassert library, accessed through the global assert table.

assert.are.equal checks equality with the == operator. The first argument is the expected value, the second is the actual value.

This works for numbers, strings, and booleans, but for tables it compares identity, not contents.
