How can I avoid "No test specified" errors in npm?

Question

I'm using [email protected] on Mac High Sierra. I want to run tests that were setup in this Stratum client project. I have run npm install successfully. But when I try and run individual tests, I get the error:

no test specified

What gives? I am in the root project directory and the tests are in my "test" folder. Here is what happens:

localhost:stratum-client-master davea$ npm install
up to date in 0.381s
localhost:stratum-client-master davea$ npm test test/callbacks.js

> [email protected] test /Users/davea/Documents/workspace/stratum-client-master
> echo "Error: no test specified" && exit 1 "test/callbacks.js"

Error: no test specified
sh: line 0: exit: too many arguments
npm ERR! Test failed.  See above for more details.

Answer 1

Try replacing

"scripts": {
  "test": "mocha"
},

in your package.json.

I get mocha not found error now – Hanna

'mocha' is not recognized as an internal or external command, – Moorwort

Mocha needs to be installed first before use, thus please run the below command npm i mocha or refer to this doc npmjs.com/package/mocha – Cilurzo

Answer 2

You're outputting exactly what the package.json file was told to output. Take a peek under scripts.

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1",
  "int-test": "mocha --require babel-core/register --recursive test"
},

Try int-test, the other command in there.

Update: The package link has changed to the following and mocha should be the default test suite. You can run the other script with npm run bump-version; the original script above can be run with npm run int-test.

"scripts": {
  "test": "mocha --recursive test",
  "bump-version": "npm version patch"
},

I did try "npm int-test" as their documentaiton recommended but got the error "Usage: npm <command> ... Did you mean one of these? test install-test" so tthen I migrated to what I had above. – Ninnyhammer

In order to run a command in the script tag, you must specify the run subcommand. npm run int-test. npm test is just a short-hand for npm run test. It might be a good idea to replace the test command with the int-test so that you can run npm test. – Bighead

Answer 3

You didn't specify which testing framework you're using such as Jest or Mocha.

In case of Jest, add this in your package.json:

"scripts" : { 
    "test" : "jest" 
 }

In the case of mocha refer to @Divyeshpal's answer.

Answer 4

The error can be for "exit 1"

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
},

Change it to this:

"scripts": {
  "test": "echo \"No test specified\""
},

This change works because exit 1 creates an error.

Answer 5

if you are using Jest and enzyme for unit testing and you have a jest.config.json config file, you can update your package.json under scripts to the following:

"scripts":{    
  "test": "jest --config=./jest.config.json --coverage",
}

Answer 6

The error can be for "exit 1"

"scripts": {
  "test": "echo \"Error: no test specified\" && exit 1"
},

Change it to this:

"scripts": {
  "test": "echo \"No test specified\""
},

This change worked for me because exit 1 created the error.

Simple, maybe not the best practice, but it worked for me, thank you! – Shanell

find and make changes in your package.json

add this on your packages.json file:

"scripts":{
    "test": "mocha --ui tdd tests/callbacks.js",
}
