+# jest-validate
+
+Generic configuration validation tool that helps you with warnings, errors and deprecation messages as well as showing users examples of correct configuration.
+
+```bash
+npm install --save jest-validate
+```
+
+## Usage
+
+```js
+import {validate} from 'jest-validate';
+
+validate(config, validationOptions); // => {hasDeprecationWarnings: boolean, isValid: boolean}
+```
+
+Where `ValidationOptions` are:
+
+```ts
+type ValidationOptions = {
+  comment?: string;
+  condition?: (option: unknown, validOption: unknown) => boolean;
+  deprecate?: (
+    config: Record<string, unknown>,
+    option: string,
+    deprecatedOptions: DeprecatedOptions,
+    options: ValidationOptions,
+  ) => boolean;
+  deprecatedConfig?: DeprecatedOptions;
+  error?: (
+    option: string,
+    received: unknown,
+    defaultValue: unknown,
+    options: ValidationOptions,
+    path?: Array<string>,
+  ) => void;
+  exampleConfig: Record<string, unknown>;
+  recursive?: boolean;
+  recursiveBlacklist?: Array<string>;
+  recursiveDenylist?: Array<string>;
+  title?: Title;
+  unknown?: (
+    config: Record<string, unknown>,
+    exampleConfig: Record<string, unknown>,
+    option: string,
+    options: ValidationOptions,
+    path?: Array<string>,
+  ) => void;
+};
+
+type Title = {
+  deprecation?: string;
+  error?: string;
+  warning?: string;
+};
+```
+
+`exampleConfig` is the only option required.
+
+## API
+
+By default `jest-validate` will print generic warning and error messages. You can however customize this behavior by providing `options: ValidationOptions` object as a second argument:
+
+Almost anything can be overwritten to suite your needs.
+
+### Options
+
+- `recursiveDenylist` – optional array of string keyPaths that should be excluded from deep (recursive) validation.
+- `comment` – optional string to be rendered below error/warning message.
+- `condition` – an optional function with validation condition.
+- `deprecate`, `error`, `unknown` – optional functions responsible for displaying warning and error messages.
+- `deprecatedConfig` – optional object with deprecated config keys.
+- `exampleConfig` – the only **required** option with configuration against which you'd like to test.
+- `recursive` - optional boolean determining whether recursively compare `exampleConfig` to `config` (default: `true`).
+- `title` – optional object of titles for errors and messages.
+
+You will find examples of `condition`, `deprecate`, `error`, `unknown`, and `deprecatedConfig` inside source of this repository, named respectively.
+
+## exampleConfig syntax
+
+`exampleConfig` should be an object with key/value pairs that contain an example of a valid value for each key. A configuration value is considered valid when:
+
+- it matches the JavaScript type of the example value, e.g. `string`, `number`, `array`, `boolean`, `function`, or `object`
+- it is `null` or `undefined`
+- it matches the Javascript type of any of arguments passed to `MultipleValidOptions(...)`
+
+The last condition is a special syntax that allows validating where more than one type is permissible; see example below. It's acceptable to have multiple values of the same type in the example, so you can also use this syntax to provide more than one example. When a validation failure occurs, the error message will show all other values in the array as examples.
+
+## Examples
+
+Minimal example:
+
+```js
+validate(config, {exampleConfig});
+```
+
+Example with slight modifications:
+
+```js
+validate(config, {
+  comment: '  Documentation: http://custom-docs.com',
+  deprecatedConfig,
+  exampleConfig,
+  title: {
+    deprecation: 'Custom Deprecation',
+    // leaving 'error' and 'warning' as default
+  },
+});
+```
+
+This will output:
+
+#### Warning:
+
+```bash
+● Validation Warning:
+
+  Unknown option transformx with value "<rootDir>/node_modules/babel-jest" was found.
+  This is either a typing error or a user mistake. Fixing it will remove this message.
+
+  Documentation: http://custom-docs.com
+```
+
+#### Error:
+
+```bash
+● Validation Error:
+
+  Option transform must be of type:
+    object
+  but instead received:
+    string
+
+  Example:
+  {
+    "transform": {
+      "\\.js$": "<rootDir>/preprocessor.js"
+    }
+  }
+
+  Documentation: http://custom-docs.com
+```
+
+## Example validating multiple types
+
+```js
+import {multipleValidOptions} from 'jest-validate';
+
+validate(config, {
+  // `bar` will accept either a string or a number
+  bar: multipleValidOptions('string is ok', 2),
+});
+```
+
+#### Error:
+
+```bash
+● Validation Error:
+
+  Option foo must be of type:
+    string or number
+  but instead received:
+    array
+
+  Example:
+  {
+    "bar": "string is ok"
+  }
+
+  or
+
+  {
+    "bar": 2
+  }
+
+  Documentation: http://custom-docs.com
+```
+
+#### Deprecation
+
+Based on `deprecatedConfig` object with proper deprecation messages. Note custom title:
+
+```bash
+Custom Deprecation:
+
+  Option scriptPreprocessor was replaced by transform, which support multiple preprocessors.
+
+  Jest now treats your current configuration as:
+  {
+    "transform": {".*": "xxx"}
+  }
+
+  Please update your configuration.
+
+  Documentation: http://custom-docs.com
+```
+
+## Example validating CLI arguments
+
+```js
+import {validate} from 'jest-validate';
+
+validateCLIOptions(argv, {...allowedOptions, deprecatedOptions});
+```
+
+If `argv` contains a deprecated option that is not specified in `allowedOptions`, `validateCLIOptions` will throw an error with the message specified in the `deprecatedOptions` config:
+
+```bash
+● collectCoverageOnlyFrom:
+
+  Option "collectCoverageOnlyFrom" was replaced by "collectCoverageFrom"
+
+  CLI Options Documentation: https://jestjs.io/docs/en/cli.html
+```
+
+If the deprecation option is still listed in the `allowedOptions` config, then `validateCLIOptions` will print the warning without throwing an error.

+# ansi-styles
+
+> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="screenshot.svg" width="900">
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 256/truecolor
+// NOTE: When converting from truecolor to 256 colors, the original color
+//       may be degraded to fit the new color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(`${style.color.ansi256(style.rgbToAnsi256(199, 20, 250))}Hello World${style.color.close}`)
+console.log(`${style.color.ansi16m(...style.hexToRgb('#abcdef'))}Hello World${style.color.close}`)
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `overline` *Supported on VTE-based terminals, the GNOME terminal, mintty, and Git Bash.*
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` allows converting between various color formats and ANSI escapes, with support for 256 and 16 million colors.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `ansi256`
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi256(style.rgbToAnsi256(100, 200, 15)); // RGB to 256 color ansi foreground code
+style.bgColor.ansi256(style.hexToAnsi256('#C0FFEE')); // HEX to 256 color ansi foreground code
+
+style.color.ansi16m(100, 200, 15); // RGB to 16 million color foreground code
+style.bgColor.ansi16m(...style.hexToRgb('#C0FFEE')); // Hex (RGB) to 16 million color foreground code
+```

+> Convert a dash/dot/underscore/space separated string to camelCase or PascalCase: `foo-bar` → `fooBar`
+
+Correctly handles Unicode strings.
+
+If you use this on untrusted user input, don't forget to limit the length to something reasonable.
+
+## Install
+
+```
+$ npm install camelcase
+```
+
+*If you need to support Firefox < 78, stay on version 5 as version 6 uses regex features not available in Firefox < 78.*
+
+## Usage
+
+```js
+const camelCase = require('camelcase');
+
+camelCase('foo-bar');
+//=> 'fooBar'
+
+camelCase('foo_bar');
+//=> 'fooBar'
+
+camelCase('Foo-Bar');
+//=> 'fooBar'
+
+camelCase('розовый_пушистый_единорог');
+//=> 'розовыйПушистыйЕдинорог'
+
+camelCase('Foo-Bar', {pascalCase: true});
+//=> 'FooBar'
+
+camelCase('--foo.bar', {pascalCase: false});
+//=> 'fooBar'
+
+camelCase('Foo-BAR', {preserveConsecutiveUppercase: true});
+//=> 'fooBAR'
+
+camelCase('fooBAR', {pascalCase: true, preserveConsecutiveUppercase: true}));
+//=> 'FooBAR'
+
+camelCase('foo bar');
+//=> 'fooBar'
+
+console.log(process.argv[3]);
+//=> '--foo-bar'
+camelCase(process.argv[3]);
+//=> 'fooBar'
+
+camelCase(['foo', 'bar']);
+//=> 'fooBar'
+
+camelCase(['__foo__', '--bar'], {pascalCase: true});
+//=> 'FooBar'
+
+camelCase(['foo', 'BAR'], {pascalCase: true, preserveConsecutiveUppercase: true})
+//=> 'FooBAR'
+
+camelCase('lorem-ipsum', {locale: 'en-US'});
+//=> 'loremIpsum'
+```
+
+## API
+
+### camelCase(input, options?)
+
+#### input
+
+Type: `string | string[]`
+
+String to convert to camel case.
+
+#### options
+
+Type: `object`
+
+##### pascalCase
+
+Type: `boolean`\
+Default: `false`
+
+Uppercase the first character: `foo-bar` → `FooBar`
+
+##### preserveConsecutiveUppercase
+
+Type: `boolean`\
+Default: `false`
+
+Preserve the consecutive uppercase characters: `foo-BAR` → `FooBAR`.
+
+##### locale
+
+Type: `false | string | string[]`\
+Default: The host environment’s current locale.
+
+The locale parameter indicates the locale to be used to convert to upper/lower case according to any locale-specific case mappings. If multiple locales are given in an array, the best available locale is used.
+
+```js
+const camelCase = require('camelcase');
+
+camelCase('lorem-ipsum', {locale: 'en-US'});
+//=> 'loremIpsum'
+
+camelCase('lorem-ipsum', {locale: 'tr-TR'});
+//=> 'loremİpsum'
+
+camelCase('lorem-ipsum', {locale: ['en-US', 'en-GB']});
+//=> 'loremIpsum'
+
+camelCase('lorem-ipsum', {locale: ['tr', 'TR', 'tr-TR']});
+//=> 'loremİpsum'
+```
+
+Setting `locale: false` ignores the platform locale and uses the [Unicode Default Case Conversion](https://unicode-org.github.io/icu/userguide/transforms/casemappings.html#simple-single-character-case-mapping) algorithm:
+
+```js
+const camelCase = require('camelcase');
+
+// On a platform with 'tr-TR'
+
+camelCase('lorem-ipsum');
+//=> 'loremİpsum'
+
+camelCase('lorem-ipsum', {locale: false});
+//=> 'loremIpsum'
+```

+
+## Usage with plugins
+
+The `pretty-format` package provides some built-in plugins, including:
+
+- `ReactElement` for elements from `react`
+- `ReactTestComponent` for test objects from `react-test-renderer`
+
+```js
+// CommonJS
+const React = require('react');
+const renderer = require('react-test-renderer');
+const {format: prettyFormat, plugins} = require('pretty-format');
+
+const {ReactElement, ReactTestComponent} = plugins;
+```
+
+```js
+// ES2015 modules and destructuring assignment
+import React from 'react';
+import renderer from 'react-test-renderer';
+import {plugins, format as prettyFormat} from 'pretty-format';
+
+const {ReactElement, ReactTestComponent} = plugins;
+```
+
+```js
+const onClick = () => {};
+const element = React.createElement('button', {onClick}, 'Hello World');
+
+const formatted1 = prettyFormat(element, {
+  plugins: [ReactElement],
+  printFunctionName: false,
+});
+const formatted2 = prettyFormat(renderer.create(element).toJSON(), {
+  plugins: [ReactTestComponent],
+  printFunctionName: false,
+});
+/*
+<button
+  onClick=[Function]
+>
+  Hello World
+</button>
+*/
+```
+
+## Usage in Jest
+
+For snapshot tests, Jest uses `pretty-format` with options that include some of its built-in plugins. For this purpose, plugins are also known as **snapshot serializers**.
+
+To serialize application-specific data types, you can add modules to `devDependencies` of a project, and then:
+
+In an **individual** test file, you can add a module as follows. It precedes any modules from Jest configuration.
+
+```js
+import serializer from 'my-serializer-module';
+expect.addSnapshotSerializer(serializer);
+
+// tests which have `expect(value).toMatchSnapshot()` assertions
+```
+
+For **all** test files, you can specify modules in Jest configuration. They precede built-in plugins for React, HTML, and Immutable.js data types. For example, in a `package.json` file:
+
+```json
+{
+  "jest": {
+    "snapshotSerializers": ["my-serializer-module"]
+  }
+}
+```
+
+## Writing plugins
+
+A plugin is a JavaScript object.
+
+If `options` has a `plugins` array: for the first plugin whose `test(val)` method returns a truthy value, then `prettyFormat(val, options)` returns the result from either:
+
+- `serialize(val, …)` method of the **improved** interface (available in **version 21** or later)
+- `print(val, …)` method of the **original** interface (if plugin does not have `serialize` method)
+
+### test
+
+Write `test` so it can receive `val` argument of any type. To serialize **objects** which have certain properties, then a guarded expression like `val != null && …` or more concise `val && …` prevents the following errors:
+
+- `TypeError: Cannot read property 'whatever' of null`
+- `TypeError: Cannot read property 'whatever' of undefined`
+
+For example, `test` method of built-in `ReactElement` plugin:
+
+```js
+const elementSymbol = Symbol.for('react.element');
+const test = val => val && val.$$typeof === elementSymbol;
+```
+
+Pay attention to efficiency in `test` because `pretty-format` calls it often.
+
+### serialize
+
+The **improved** interface is available in **version 21** or later.
+
+Write `serialize` to return a string, given the arguments:
+
+- `val` which “passed the test”
+- unchanging `config` object: derived from `options`
+- current `indentation` string: concatenate to `indent` from `config`
+- current `depth` number: compare to `maxDepth` from `config`
+- current `refs` array: find circular references in objects
+- `printer` callback function: serialize children
+
+### config

+### Example of serialize and test
+
+This plugin is a pattern you can apply to serialize composite data types. Side note: `pretty-format` does not need a plugin to serialize arrays.
+
+```js
+// We reused more code when we factored out a function for child items
+// that is independent of depth, name, and enclosing punctuation (see below).
+const SEPARATOR = ',';
+function serializeItems(items, config, indentation, depth, refs, printer) {
+  if (items.length === 0) {
+    return '';
+  }
+  const indentationItems = indentation + config.indent;
+  return (
+    config.spacingOuter +
+    items
+      .map(
+        item =>
+          indentationItems +
+          printer(item, config, indentationItems, depth, refs), // callback
+      )
+      .join(SEPARATOR + config.spacingInner) +
+    (config.min ? '' : SEPARATOR) + // following the last item
+    config.spacingOuter +
+    indentation
+  );
+}
+
+const plugin = {
+  test(val) {
+    return Array.isArray(val);
+  },
+  serialize(array, config, indentation, depth, refs, printer) {
+    const name = array.constructor.name;
+    return ++depth > config.maxDepth
+      ? `[${name}]`
+      : `${config.min ? '' : `${name} `}[${serializeItems(
+          array,
+          config,
+          indentation,
+          depth,
+          refs,
+          printer,
+        )}]`;
+  },
+};
+```
+
+```js
+const val = {
+  filter: 'completed',
+  items: [
+    {
+      text: 'Write test',
+      completed: true,
+    },
+    {
+      text: 'Write serialize',
+      completed: true,
+    },
+  ],
+};
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+  "filter": "completed",
+  "items": Array [
+    Object {
+      "completed": true,
+      "text": "Write test",
+    },
+    Object {
+      "completed": true,
+      "text": "Write serialize",
+    },
+  ],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    indent: 4,
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+    "filter": "completed",
+    "items": Array [
+        Object {
+            "completed": true,
+            "text": "Write test",
+        },
+        Object {
+            "completed": true,
+            "text": "Write serialize",
+        },
+    ],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    maxDepth: 1,
+    plugins: [plugin],
+  }),
+);
+/*
+Object {
+  "filter": "completed",
+  "items": [Array],
+}
+*/
+```
+
+```js
+console.log(
+  prettyFormat(val, {
+    min: true,
+    plugins: [plugin],
+  }),
+);
+/*
+{"filter": "completed", "items": [{"completed": true, "text": "Write test"}, {"completed": true, "text": "Write serialize"}]}
+*/
+```
+
+### print
+
+The **original** interface is adequate for plugins:
+
+- that **do not** depend on options other than `highlight` or `min`
+- that **do not** depend on `depth` or `refs` in recursive traversal, and
+- if values either
+  - do **not** require indentation, or
+  - do **not** occur as children of JavaScript data structures (for example, array)
+
+Write `print` to return a string, given the arguments:
+
+- `val` which “passed the test”
+- current `printer(valChild)` callback function: serialize children
+- current `indenter(lines)` callback function: indent lines at the next level
+- unchanging `config` object: derived from `options`
+- unchanging `colors` object: derived from `options`
+
+The 3 properties of `config` are `min` in `options` and:
+
+- `spacing` and `edgeSpacing` are **newline** if `min` is `false`
+- `spacing` is **space** and `edgeSpacing` is **empty string** if `min` is `true`
+
+Each property of `colors` corresponds to a property of `theme` in `options`:
+
+- the key is the same (for example, `tag`)
+- the value in `colors` is a object with `open` and `close` properties whose values are escape codes from [ansi-styles](https://github.com/chalk/ansi-styles) for the color value in `theme` (for example, `'cyan'`)
+
+### Example of print and test
+
+This plugin prints functions with the **number of named arguments** excluding rest argument.
+
+```js
+const plugin = {
+  print(val) {
+    return `[Function ${val.name || 'anonymous'} ${val.length}]`;
+  },
+  test(val) {
+    return typeof val === 'function';
+  },
+};
+```
+
+```js
+const val = {
+  onClick(event) {},
+  render() {},
+};
+
+prettyFormat(val, {
+  plugins: [plugin],
+});
+/*
+Object {
+  "onClick": [Function onClick 1],
+  "render": [Function render 0],
+}
+*/
+
+prettyFormat(val);
+/*
+Object {
+  "onClick": [Function onClick],
+  "render": [Function render],
+}
+*/
+```
+
+This plugin **ignores** the `printFunctionName` option. That limitation of the original `print` interface is a reason to use the improved `serialize` interface, described above.
+
+```js
+prettyFormat(val, {
+  plugins: [pluginOld],
+  printFunctionName: false,
+});
+/*
+Object {
+  "onClick": [Function onClick 1],
+  "render": [Function render 0],
+}
+*/
+
+prettyFormat(val, {
+  printFunctionName: false,
+});
+/*
+Object {
+  "onClick": [Function],
+  "render": [Function],
+}
+*/
+```
