busted test specs read naturally without being too verbose. You can
even chain asserts and negations, such as assert.not.equals. Nest
blocks of tests with contextual descriptions using describe, and add
tags to blocks so you can run arbitrary groups of tests.
.
An extensible assert library allows you to extend and craft your own
assert functions specific to your case with method chaining. A modular
output library lets you add on your own output format, along with the
default pretty and plain terminal output, JSON with and without
streaming, and TAP-compatible output that allows you to run busted
specs within most CI servers. You can even register phrases for
internationaliation with custom or built-in language packs.
