'ava' is not recognized as an internal or external command - When testing compatibility

[litehacker]

Describe the bug Following the installation and testing process leads to the error:

'ava' is not recognized as an internal or external command,

To Reproduce Followed the installation process after creating clean node.

package.json

{
  "name": "backend",
  "version": "0.0.1",
  "description": "Uses `pdfreader` [package](https://www.npmjs.com/package/pdfreader)",
  "main": "index.js",
  "scripts": {
    "start:dev": "nodemon",
    "test": "echo \"Error: no test specified\" && exit 1",
    "build": "rimraf ./build && tsc",
    "start": "npm run build && node build/index.js"
  },
  "author": "Giorgi Gvimradze",
  "license": "ISC",
  "devDependencies": {
    "@tsconfig/node14": "^1.0.1",
    "@types/node": "^14.18.20",
    "nodemon": "^2.0.16",
    "rimraf": "^3.0.2",
    "ts-node": "^10.8.0",
    "typescript": "^4.7.2"
  },
  "dependencies": {
    "pdfreader": "^2.0.0"
  }
}

Expected behavior I expect it to pass the test. since it's required node v 14, I got it.

Screenshots, outputs, or logs

Hi!

Indeed, the testing instructions are incorrect. ava is a development dependency of pdfreader, so it's not installed when you add pdfreader as a dependency of your own project.

Can you try running them with the command npx ava (instead of just ava) and tell me if it works, please?

Hello. I tested with npx ava but only got × Couldn’t find any files to test. Same result when I do npm install inside the "node_modules/pdfreader" folder.

• Windows 10
• Node 16.10.0
• npm 7.24.0

Even if you run npx ava from the pdfreader directory?

Yes. Tried npx ava insdie "node_modules/pdfreader". Same result.

Just realised there is no "test" folder inside "node_modules/pdfreader", because its listed in ".npmignore" to reduce package size.

Good catch! That makes sense, as test files are not needed by projects that rely on pdfreader as a dependency.

If you need to run pdfreader's tests, you need to git clone https://github.com/adrienjoly/npm-pdfreader.git.
