What's new in Midje 1.5

A tutorial introduction

A tutorial introduction (and sales pitch) for clojure.test users

Concept index

Many of the examples in the following pages (and some others besides) can be found in the tests-as-documentation directory.

The core

• Facts: Midje's equivalent of a test
• Checkables: Midje's equivalent of an assertion
• Checkers: Prepackaged functions that perform common checks
  • Simple checkers
  • Checking sequential collections
  • Checking maps and records
  • Checking sets
  • Combining checkers to create new ones
• Repl tools: A quick introduction
• Lein-midje basics: Checking facts, both batch and incrementally (autotest)

Bending Midje to your will

• Using metadata to filter facts
• Print levels: Control verbosity
• Configuration files: Control everything
• Colorizing: Highlight failing and future facts
• Customizing reporting: Making Midje speak such that your continuous build server (for example) understands
• Production mode: Preventing Midje code from being compiled into production code

Beyond the basics

• Setup and teardown
• Future facts: "Commenting out" facts in a way that prevents you from forgetting about them
• Tabular facts: Shorthand for checking multiple sets of values
• Chatty checkers: Checkers that explain more about a failure
• Testing private functions
• More about lein-midje

Top-down development

• The idea
• A video introduction
• Describing one checkable's prerequisites
  • Variant prerequisite arrows
  • Prerequisites and protocols: Extra work is required to override protocol functions in facts
  • Using private functions in prerequisites
• Establishing fact-wide prerequisites

Integration

• Midje-mode: Emacs mode for using Midje with a REPL
• clojure-jump-to-file: Jump to a line of Clojure code from any Emacs buffer (usually a shell buffer)
• Cascalog support

Videos

• An introduction to Midje for clojure.test users
• An example showing [top-down testing]] using [[metaconstants]] ([alternate download)
• An Emacs minor mode for Midje
• Emacs code to jump to a particular location in a Clojure file

Miscellany

• Why is it called "Midje"?
• Syntax errors that will not be fixed
• Collection checkers and strings
• AOT-compiling metaconstants: It should usually work, but here's what to do if it doesn't
• Partial prerequisites: Undescribed function calls can go to the real function
• Defining checkers for use in prerequisites
• Mixing facts and source code
• Metaconstants as partial packets of values
• Caching: Checking memoization and caching
• Background: Now-discouraged forms that combine setup/teardown with fact-wide prerequisites
  • How to use for setup and teardown
  • How to use for fact-wide prerequisites

Reference

• Extended equality
• Syntax and a little semantics
  • Checkable arrows
  • Variant prerequisite arrows
• Lein midje
• Working in the repl
  • Repl tools
  • The compendium: Working with loaded facts
  • Autotesting: Tracking file changes and reloading facts
