Colortape: Tape/node-tap Test Output Colorizer

0.1.2 · abandoned · verified Sun Apr 19

Colortape is a command-line utility designed to add color to the test output of `tape` and `node-tap` JavaScript testing frameworks. It functions either as a direct wrapper for the test command, executing the test file and formatting its output, or by accepting the raw test output via a pipe. The package is currently at version 0.1.2, which was last published over seven years ago, indicating an abandoned status with no active development or maintenance. Its primary differentiator is its singular focus on colorizing output for these specific testing libraries, providing a simple, albeit unmaintained, solution for visual enhancement of test results without modifying the underlying test runners. Due to its abandonment, users should be aware of potential compatibility issues with newer Node.js versions or `tape`/`node-tap` releases, and the absence of security updates.

Common errors

```
sh: colortape: command not found
```
cause The `colortape` executable is not in your system's PATH, typically occurring when installed locally as a dev dependency but run globally.

fix If `colortape` is installed locally, run it via `npx colortape` or define an npm script in `package.json` (e.g., `"test": "colortape test/**/*.js"`) and run `npm test`. If you intend to use it globally, ensure it's installed with `npm install -g colortape`.
```
(No color output appears in the terminal)
```
cause Color output might be suppressed due to the terminal environment not supporting ANSI escape codes, or if the output is being redirected where colors are automatically stripped.

fix Ensure your terminal application is configured to support ANSI escape codes. If running in a CI/headless environment, check if `FORCE_COLOR=1` (a common environment variable for many colorizers) is needed, although `colortape` does not explicitly document support for it.

Warnings

breaking The `colortape` package is abandoned, with the last update over seven years ago. This means there will be no future bug fixes, security patches, or compatibility updates for newer Node.js versions, `tape`, or `node-tap`.
Fix: Consider using a more actively maintained test reporter or colorizer, or fork the project for self-maintenance. Evaluate project dependencies for potential security vulnerabilities that may arise from unmaintained software.
gotcha When using `colortape` via piping (`tape test.js | colortape`), the exit code of `colortape` itself will not reflect the success or failure of the `tape` tests. It will typically exit with `0` (success) if the piping operation itself was successful.
Fix: To correctly check the test outcome in a CI/scripting environment when piping, use `$PIPESTATUS` (in Bash/Zsh) or `$LASTEXITCODE` (in PowerShell) to inspect the exit code of the `tape` command. The recommended approach is to use `colortape` as a direct wrapper command (`colortape test.js`) which correctly propagates the `tape` exit code.
gotcha `colortape` is not officially supported on Windows environments, and its behavior or stability cannot be guaranteed, as indicated in the documentation.
Fix: Users on Windows may encounter unexpected issues. It's recommended to test thoroughly or use alternative solutions known to be compatible with Windows. Running in a Linux subsystem (WSL) might provide a more reliable experience for development.

Install

npm install colortape npm
yarn add colortape yarn
pnpm add colortape pnpm

Imports

colortape
wrong:
```
import colortape from 'colortape';
```
correct:
```
colortape test/foo.js
```
Colortape is a command-line interface (CLI) tool and does not expose a module API for programmatic import. It's intended to be run directly from the terminal or via npm scripts.
colortape CLI (piped)
wrong:
```
const colortape = require('colortape'); colortape.pipe(tapeOutput);
```
correct:
```
tape test/foo.js | colortape
```
While `colortape` can process piped input, it does so as a separate process. Attempting to `require` and programmatically pipe to it is not supported by the package's design.
colortape (internal utilities)
wrong:
```
import { colorizeOutput } from 'colortape';
```
correct:
```
N/A (no public API)
```
The `colortape` package does not export any named functions or objects for programmatic use. Its functionality is exclusively exposed through its command-line interface.

Quickstart

Demonstrates how to set up `tape` and `colortape`, write a basic test file, and then execute it using `colortape` as the wrapper command to display colorized test output via an npm script or direct CLI execution.

npm install --save-dev tape colortape

// --- test/basic.js ---
const test = require('tape');

test('simple synchronous test', function (t) {
  t.plan(1);
  t.ok(true, 'this assertion should pass');
});

test('another test', function (t) {
  t.plan(2);
  t.equal(1 + 1, 2, 'addition works');
  t.notOk(false, 'negation works');
});

test('failing test example', function (t) {
  t.plan(1);
  t.equal('hello', 'world', 'this assertion should fail');
});
// -------------------

// Add to your package.json scripts:
// "scripts": {
//   "test": "colortape test/basic.js"
// }

// Then run from your terminal:
// npm test

// Alternatively, run directly if installed globally or via npx:
// colortape test/basic.js
