no-missing-tests.md

Disallow files without a corresponding test file (square/no-missing-tests)

Ensuring that files have corresponding test files can be helpful towards improving test coverage.

Rule Details

This rule enforces that the specified files have corresponding test files.

Examples

Example entry in overrides in the .eslintrc.js configuration file used to enable this rule:

const config = {
  files: ['app/**/*.{js,ts}'],
  rules: {
    'square/no-missing-tests': [
      'error',
      [
        {
          filePath: `${__dirname}/app`,
          testPaths: [
            `${__dirname}/tests/integration`,
            `${__dirname}/tests/unit`,
          ],
        },
      ],
    ],
  },
};

Example implementation file and test file pair that would be enforced:

• app/components/my-component.js
• tests/unit/components/my-component-test.js

Migration

There's an autofixer in the rule implementation that can be uncommented as desired.

Configuration

• object[]
  • string -- filePath -- path to files that should have tests
  • string[] -- testPaths -- paths to possible test file locations to check
  • boolean -- hasTestSuffix -- whether the test files end in -test (default true)
