9.0.2 (2021-06-06)

Bug Fixes

9.0.1 (2021-05-28)

Bug Fixes

9.0.0 (2021-05-27)

Bug Fixes

Features

Performance Improvements

  • compiler: reuse cacheFS from jest to reduce file system reading (#679) (f5d9d4b)
  • config: set skipLibCheck: true if not defined in tsconfig (#678) (0df3ce1)

BREAKING CHANGES

  • Drop support for Angular < 9.0, see https://angular.io/guide/releases#support-policy-and-schedule.
  • Drop support for Node.js version 10 since it becomes EOL on 2021-04-30. Required Node version now is >=12.13.0.
  • Require Jest 27.
  • Users who are using import 'jest-preset-angular' should change to import 'jest-preset-angular/setup-jest'
  • transformers: The AST transformers InlineFilesTransformer and StripStylesTransformer are REMOVED and default jest-preset-angular uses AST transformers from @angular/compiler-cli and @ngtools/webpack. One should remove the old transformers from the jest config.
  • compiler: jest-preset-angular now switches to default to use its own transformer which wraps around ts-jest to transform codes.

Users who are currently doing in jest config

// jest.config.js
module.exports = {
    // [...]
    transform: {
      '^.+\\.(ts|js|html)$': 'ts-jest',
    },
}

should change to

// jest.config.js
module.exports = {
    // [...]
    transform: {
      '^.+\\.(ts|js|html)$': 'jest-preset-angular',
    },
}
  • serializers:: snapshot serializer paths have been changed:
    • 'jest-preset-angular/build/AngularNoNgAttributesSnapshotSerializer.js' is changed to 'jest-preset-angular/build/serializers/no-ng-attributes.
    • 'jest-preset-angular/build/AngularSnapshotSerializer.js' is changed to 'jest-preset-angular/build/serializers/ng-snapshot.
    • 'jest-preset-angular/build/HTMLCommentSerializer.js' is changed to 'jest-preset-angular/build/serializers/html-comment.
  • When generating a new project from Angular CLI, by default the tsconfig.json doesn't contain any path mappings hence removing moduleNameMapper from preset will make sure that the preset works in pair with tsconfig.json. Ones who are relying on the value of moduleNameMapper from the preset should create their own moduleNameMapper config manually or via ts-jest util https://kulshekhar.github.io/ts-jest/docs/getting-started/paths-mapping.

If you wish to reuse the old configuration of moduleNameMapper, you can put this into your Jest config

moduleNameMapper: {
  '^src/(.*)$': '<rootDir>/src/$1',
  '^app/(.*)$': '<rootDir>/src/app/$1',
  '^assets/(.*)$': '<rootDir>/src/assets/$1',
  '^environments/(.*)$': '<rootDir>/src/environments/$1',
}
  • By default, if skipLibCheck is not defined in tsconfig, jest-preset-angular will set it to true. If one wants to have it as false, one can set explicitly in tsconfig.
  • compiler: jest-preset-angular now switches to default to use its own transformer which wraps around ts-jest to transform codes.

Users who are currently doing in jest config

// jest.config.js
module.exports = {
    // [...]
    transform: {
      '^.+\\.(ts|js|html)$': 'ts-jest',
    },
}

should change to

// jest.config.js
module.exports = {
    // [...]
    transform: {
      '^.+\\.(ts|js|html)$': 'jest-preset-angular',
    },
}

9.0.0-next.13 (2021-04-18)

BREAKING CHANGES

  • Drop support for Node.js version 10 since it becomes EOL on 2021-04-30. To support Angular 12, Node.js 12.13+ or 14.15+ is required.

9.0.0-next.12 (2021-03-31)

Bug Fixes

9.0.0-next.11 (2021-03-21)

Features

  • config: load zone ESM when running jest in ESM mode (#892) (e03ec19), closes #751

BREAKING CHANGES

8.4.0 (2021-03-04)

Features

DEPRECATIONS

  • Import serializer via 'jest-preset-angular/build/AngularNoNgAttributesSnapshotSerializer.js' is deprecated in favor of 'jest-preset-angular/build/serializers/no-ng-attributes'
  • Import serializer via 'jest-preset-angular/build/AngularSnapshotSerializer.js' is deprecated in favor of 'jest-preset-angular/build/serializers/ng-snapshot'
  • Import serializer via 'jest-preset-angular/build/HTMLCommentSerializer.js' is deprecated in favor of 'jest-preset-angular/build/serializers/html-comment'
  • Import setup file via import 'jest-preset-angular' is deprecated in favor of import 'jest-preset-angular/setup-jest'

9.0.0-next.8 (2021-02-12)

Features

  • compiler: use constructor downlevel ctor transformer for isolatedModules: true (#792) (00c71ce)
  • presets: add type definition for presets entry point (#801) (e4ff0c0)

9.0.0-next.6 (2021-01-14)

Features

  • compiler: support ESM for isolatedModules: false (#721) (a2166f8)
  • compiler: use replace-resources for isolatedModules: true (#717) (76c25d2)
  • presets: add ESM preset (#723) (b0073b0)

9.0.0-next.5 (2021-01-06)

Features

  • compiler: use replace-resources transformer from Angular (#708) (1b20c19)
  • utils: add es2015 to ngcc script's properties (#701) (a13070b)

BREAKING CHANGES

  • isolatedModules: true will use inline-files and strip-styles transformers as default transformers.
  • isolatedModules: false will use replace-resources transformer from @ngtools/webpack (besides the existing downlevel-ctor transformer). This will make jest-preset-angular become closer to what Angular CLI does with Karma + Jasmine.
  • For users who migrate from v8.3.2 to 9.0.0, any references to 'jest-preset-angular/build/InlineFilesTransformer' and 'jest-preset-angular/build/StripStylesTransformer' should be removed from jest config.
  • For users who migrate from 9.0.0-next.4, any references to jest-preset-angular/build/transformers/inline-files and jest-preset-angular/build/transformers/inline-files should be removed from jest config.

  • config: switch to tsconfig for jest-preset.js

9.0.0-next.0 (2020-10-18)

Chore

BREAKING CHANGES

We are working on Ivy compatibility for this preset. This requires introducing a different Jest transformer than the default one from ts-jest. To get updates on this work, please subscribe to #409

  • Users who are using import 'jest-preset-angular' should change to import 'jest-preset-angular/setup-jest'
  • Drop support for Angular < 8.0, see https://angular.io/guide/releases#support-policy-and-schedule
  • transformers: The AST transformers InlineFilesTransformer and StripStylesTransformer are REMOVED and default jest-preset-angular uses AST transformers from @angular/compiler-cli. One should remove the old transformers from the jest config.
  • serializers: One is using all jest-preset-angular snapshot serializers should change jest config to have:
// jest.config.js
const jestPresetAngularSerializers = require('jest-preset-angular/build/serializers')

module.exports = {
     // [...]
     snapshotSerializers: jestPresetAngularSerializers,
}

One is using one of jest-preset-angular snapshot serializers should change jest config to have:

// jest.config.js
module.exports = {
     // [...]
     snapshotSerializers: [
          'jest-preset-angular/build/serializers/html-comment'
     ]
}

or

// package.json
{
      // [...]
     "jest": {
           snapshotSerializers: [
                "jest-preset-angular/build/serializers/html-comment"
           ]
      }

Bug Fixes

8.0.0 (2019-10-21)

Features

  • breaking: Refine ast-transformer behavior: only transform styles-assignments inside @Component (#261) and TypeScript v2.9 createStringLiteral is polyfilled if an older version is used (#272).
  • breaking: Restructure project with src and build folder (#307).
  • breaking: Support tsconfig.spec.json in root folder by default (#309).

BREAKING CHANGES

  • If the astTransformers are referenced in a custom jest config, [ 'jest-preset-angular/build/InlineFilesTransformer', 'jest-preset-angular/build/StripStylesTransformer'] have to be set instead.
  • Serializers, transformers and setupJest have to be referenced from the jest-preset-angular/build/-folder in a custom config. Existing references have to be aligned.
  • If your tsconfig.spec.json is located in src, move it to your root folder and adjust the referenced files and paths inside, or align your jest configuration as discussed in the README.md.
  • In an Angular 8 project or higher, core-js should no longer be a dependency declared in package.json, unless it's imported manually in the code.

  • If the global value of the configuration was overridden, adjust
    • The option "__TRANSFORM_HTML__": true is not required anymore. Instead the "stringifyContentPathRegex": "\\.html$" should be used inside the ts-jest-configuration.
    • Change the assignment identifier from tsConfigFile to tsConfig.
    • Add the astTransformers: [require.resolve('jest-preset-angular/InlineHtmlStripStylesTransformer')] so Jest can work with templateUrl-assignments in Component decorators.
  • If transform was overridden, remove the entry pointing at preprocessor.js and add "^.+\\.(ts|js|html)$": "ts-jest" to the transform-object.
  • If in doubt, check the configuration example in jest-preset.json.
