+# jest-validate
+
+Generic configuration validation tool that helps you with warnings, errors and deprecation messages as well as showing users examples of correct configuration.
+
+```
+npm install --save jest-validate
+```
+
+## Usage
+
+```js
+import {validate} from 'jest-validate';
+
+validate(
+  config: Object,
+  options: ValidationOptions,
+); // => {hasDeprecationWarnings: boolean, isValid: boolean}
+```
+
+Where `ValidationOptions` are:
+```js
+type ValidationOptions = {
+  comment?: string,
+  condition?: (option: any, validOption: any) => boolean,
+  deprecate?: (
+    config: Object,
+    option: string,
+    deprecatedOptions: Object,
+    options: ValidationOptions
+  ) => true,
+  deprecatedConfig?: {[key: string]: Function},
+  error?: (
+    option: string,
+    received: any,
+    defaultValue: any,
+    options: ValidationOptions,
+  ) => void,
+  exampleConfig: Object,
+  title?: Title,
+  unknown?: (
+    config: Object,
+    exampleConfig: Object,
+    option: string,
+    options: ValidationOptions
+  ) => 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
+
+* `comment` – optional string to be rendered bellow 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.
+* `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.
+
+## Examples
+
+Minimal example:
+
+```js
+validate(config, {exampleConfig});
+```
+
+Example with slight modifications:
+
+```js
+validate(config, {
+  comment: '  Documentation: http://custom-docs.com',
+  exampleConfig,
+  deprecatedConfig,
+  title: {
+    deprecation: 'Custom Deprecation',
+    // leaving 'error' and 'warning' as default
+  }
+});
+```
+
+This will output:
+
+#### Warning:
+
+```
+● 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:
+
+```
+● Validation Error:
+
+  Option transform must be of type:
+    object
+  but instead received:
+    string
+
+  Example:
+  {
+    "transform": {"^.+\\.js$": "<rootDir>/preprocessor.js"}
+  }
+
+  Documentation: http://custom-docs.com
+```
+
+#### Deprecation
+Based on `deprecatedConfig` object with proper deprecation messages. Note custom title:
+
+```
+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.
+
