eslint-plugin-no-snapshot-testing

library1.0.61jsnpmunverified

An ESLint plugin (v1.0.61) that enforces a rule disallowing snapshot testing in Jest. It prevents calls to `toMatchSnapshot` and `toMatchInlineSnapshot`, offering an auto-fix to remove them. This package is a niche utility for teams that ban snapshot testing. It has a simple setup, only one rule, and is dependency-light. No known major alternative exists with identical focus.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

plugin (default)

✓ plugins: ['no-snapshot-testing']

✗ plugins: ['eslint-plugin-no-snapshot-testing']

ESLint expects short plugin name; the 'eslint-plugin-' prefix is omitted.

rule (no-snapshot-testing/no-snapshot-testing)

✓ rules: { 'no-snapshot-testing/no-snapshot-testing': 'error' }

✗ rules: { 'no-snapshot-testing/no-snapshot': 'error' }

The rule name is 'no-snapshot-testing', not a shorter variant.

rule options

✓ rules: { 'no-snapshot-testing/no-snapshot-testing': ['error', { ... }] }

✗ rules: { 'no-snapshot-testing/no-snapshot-testing': ['error', { ... }] }

No official options documented; plugin is simple.

Shows ESLint config enabling the plugin and rule, and an example of a flagged snapshot call.

// .eslintrc.js module.exports = { plugins: ['no-snapshot-testing'], rules: { 'no-snapshot-testing/no-snapshot-testing': 'error', }, }; // test.js const x = 1; expect(x).toMatchSnapshot(); // ESLint error + fix removes this line

Debug

Known issues

gotchaThe rule name is repetitive: 'no-snapshot-testing/no-snapshot-testing'.

fix

Use exactly as documented; no alternative rule name exists.

affects: >=1.0.0

gotchaOnly disallows Jest snapshot matchers; not other snapshot-like patterns (e.g., manual file snapshots).

fix

Extend rule or use additional ESLint configurations if needed.

affects: >=1.0.0

gotchaAuto-fix removes the entire `expect(...).toMatchSnapshot()` line; may remove other chained matchers if on same line.

fix

Ensure snapshot call is on its own line before auto-fix.

affects: >=1.0.0

gotchaNo support for custom matchers that wrap snapshot testing.

fix

Plugin is intentionally limited; consider custom ESLint rules for advanced cases.

affects: >=1.0.0

Errors

Common errors & fixes

ESLint couldn't find the plugin "eslint-plugin-no-snapshot-testing".

Plugin not installed or ESLint cannot resolve it.

fix

Run `npm install eslint-plugin-no-snapshot-testing --save-dev` and check node_modules.

Rule "no-snapshot-testing/no-snapshot-testing" is not defined.

Plugin not listed in 'plugins' array or misspelled.

fix

Add 'no-snapshot-testing' to plugins in .eslintrc.

Cannot read property 'rule' of undefined

Invalid plugin configuration: using 'rules' with wrong format.

fix

Ensure plugins array contains 'no-snapshot-testing' and rules object key is 'no-snapshot-testing/no-snapshot-testing'.
