Code

Verified usage

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

plugin

✓ ['mock-imports', { redirects: [...] }] in .babelrc or babel.config.js

✗ require('babel-plugin-mock-imports')

The plugin is a Babel plugin and should be listed in Babel configuration, not directly required in code.

redirects

✓ pattern: '.(svg)$', location: 'path/to/mock'

✗ pattern: /.svg$/

Pattern is a string that will be passed to RegExp constructor, not a RegExp literal.

type definition

✓ No official type definitions; use @types/babel__core for general Babel types.

Plugin does not ship TypeScript types. For Babel config typing, use @types/babel__core.

Redirects all .svg imports to a mock component.

module.exports = { plugins: [ ['mock-imports', { redirects: [ { pattern: '.svg$', location: 'path/to/mocked/react/component' } ] }] ] };

Debug

Known issues

gotchaPattern strings are evaluated as RegExp; special characters must be escaped correctly.

fix

Escape regex special characters in pattern strings, or use strings that are safe for RegExp.

affects: >=0.0.1

gotchaPlugin replaces import source strings but does not transform default/namespace imports; ensure mock modules export the same interface.

fix

Ensure mock modules export the same symbols as the original modules.

affects: >=0.0.1
