nodejs-test

Options for package.json script configured tests.

Your preferred test runner is configured via the package.json#scripts.test field.

The only expectation from pants is that the test script can accept a variadic number of path arguments, relative to the package.json, and that any configuration files are file dependencies to the package_json.

Simple example:

Consider a directory-layout:

├── BUILD
├── src/
│   ├── BUILD
│   ├── test/
│   │   ├── BUILD
│   │   └── index.test.js
│   └── index.js
└── package.json

where package.json contains

package.json
{
    ...
    "scripts": {
        "test": "mocha"
    },
    "devDependencies: {
        ...
    }
}

Executing pants test src/test/index.test.js will cause the equivalent of mocha src/test/index.test.js to run.

Basic options​

skip​

--[no-]nodejs-test-skip
PANTS_NODEJS_TEST_SKIP

If true, don't use Node.js tests when running pants test.

Advanced options​

PANTS_NODEJS_TEST_COVERAGE_OUTPUT_DIR

coverage_output_dir = <str>
default: {distdir}/coverage/js/{target_spec}

Path to write the NodeJS coverage reports to. Must be relative to the build root.

Replacements:

  • {distdir} is replaced with the Pants distdir.
