tape-watcher

Inspired by tape-watch, since that was the fastest solution I could find to run tape tests in watch mode, but I got annoyed by the memory leak warnings it was throwing and also thought I could make the experience a bit more fun.

Features

• Runs tape tests after modifications, while keeping the require cache for node_module files, saving on startup time
• Only reports details for failing tests
• Prints a meaningful stack trace for runtime exceptions
• A watchdog lets you know if you forgot about t.end(), the process doesn't just hangs up waiting for it
• Provides an interactive terminal that lets you set how you want to see your result during runtime

Usage

From command line if installed globally:

tape-watcher 'src/**.spec.js'

Or install locally as a dev dependency and add it to package json scripts:

"tdd": "tape-watcher src/**.spec.js"

Commands during run:

Type in the letters while the watch mode is active and press enter. A new run will be triggered with the changed option taking effect.

• d: toggle showing actual and expected or their colored diff
• i: toggle printing values with or without and indentation
• 1 to 9: set objectPrintDepth for printing
• r: manually trigger the re-run of all the tests (not needed if watch is working well)
• q: quit, exit process (same as hitting ctrl + c)

Install

npm i tape-watcher --save-dev
