jest-environment-serverless\n\nRun your [Serverless](https://serverless.com) tests using Jest, quickly and easily! This project exposes a [Lambda Wrapper](https://github.com/nordcloud/lambda-wrapper) to your tests in order to make it effortless and easy to test your lambdas.\n\nInstalling is as easy as:\n\n```shell\nnpm install serverless jest jest-environment-serverless\n```\n\n## Usage\n\nUpdate your Jest configuration to set the [testEnvironment](https://jestjs.io/docs/en/configuration#testenvironment-string) to `jest-environment-serverless`:\n\n_package.json_\n```json\n{\n  \"name\": \"my-project\",\n  \"scripts\": {\n    \"test\": \"jest\"\n  },\n  \"jest\": {\n    \"testEnvironment\": \"jest-environment-serverless\"\n  }\n}\n```\n\nUse Serverless in your tests:\n\n```javascript\ndescribe('Hello Lambda', () =\u003e {\n  let wrapper;\n\n  beforeAll(async () =\u003e {\n    wrapper = await LambdaWrapper.getWrapper('hello');\n  });\n\n  it('says hello', async () =\u003e {\n    const event = { name: 'Bob' };\n    const response = await wrapper.run(event);\n    expect(response).toHaveProperty('message', 'Hi Bob!');\n  });\n});\n```\n\nRun your tests:\n\n```shell\nnpm test\n```\n\n## API\n\n### `global.LambdaWrapper`\n\nThis global variable provides convenient access to the [lambda-wrapper](https://github.com/nordcloud/lambda-wrapper) module in order to simulate lambda executions for the given events and contexts, fully initialized with your `Serverless` configuration, providing a more accurate and thorough testing scenario than attempting to invoke and test your lambdas directly.\n\n#### `getWrapper()`\n\nWhen provided with a valid `Serverless` function name, `getWrapper` will return a configured, ready-to-run [lambda wrapper](https://github.com/nordcloud/lambda-wrapper).\n\nWith a simple `serverless.yml`\n```yaml\nservice: jest-test-suite\nprovider:\n  name: aws\n  runtime: nodejs8.10\n  region: us-east-1\n  environment:\n    STAGE: prod-stage-test\nfunctions:\n  hello:\n    handler: handler.hello\n    environment:\n      HELLO: \"world ${self:provider.region}\"\n```\n\nYou can obtain a reference to the `hello` lambda in order to simulate various conditions and assert the expected behaviors:\n\n```javascript\ndescribe('Hello Lambda', () =\u003e {\n  let wrapper;\n\n  beforeAll(async () =\u003e {\n    wrapper = await LambdaWrapper.getWrapper('hello');\n  });\n\n  it('says hello', async () =\u003e {\n    const event = { name: 'Bob' };\n    const response = await wrapper.run(event);\n    expect(response).toHaveProperty('message', 'Hi Bob!');\n  });\n});\n```\n\n### `global.ServerlessWrapper`\n\nThis global variable provides access to a number of properties that can be safely ignored in nearly all but the most challenging test scenarios. These are primarily used by the [LambdaWrapper](#global.LambdaWrapper) in order to discover the service and configuration for a given lambda during testing.\n\n#### `Serverless`\n\nThis provides direct access to the `Serverless` class.\n\n#### `rootDir`\n\nExposes the root directory used by `Serverless` to load the configuration and plugins from. By default, this value is set to the `cwd`.\n\n#### `serverless`\n\nThis provides direct access to the initialized `Serverless` instance in case it is needed to help assert or verify anything during testing. With this, you can access:\n- processed configuration\n- loaded services\n- loaded plugins\n- variables\n\nYou can also dynamically modify the configuration or services to assist while testing, without needing to manage multiple test projects or copying files to temporary directories.\n\n#### `getEnv()`\n\nExposes the environment variables for the function defined in your Serverless Configuration. For example:\n\nWith a simple `serverless.yml`\n```yaml\nservice: jest-test-suite\nprovider:\n  name: aws\n  runtime: nodejs8.10\n  region: us-east-1\n  environment:\n    STAGE: prod-stage-test\nfunctions:\n  hello:\n    handler: handler.hello\n    environment:\n      HELLO: \"world ${self:provider.region}\"\n```\n\nCalling `getEnv` would return:\n```javascript\n// This is the name of the lambda declared in the \"functions\" block in the\n// serverless.yml\nconst envVars = ServerlessWrapper.getEnv('hello');\nassert.deepEqual(envVars, { HELLO: 'world us-east-1' });\n```\n\n#### `setEnv()`\n\nUpdates `process.env` with the environment variables for the function defined in your Serverless Configuration. For example:\n\nWith a simple `serverless.yml`\n```yaml\nservice: jest-test-suite\nprovider:\n  name: aws\n  runtime: nodejs8.10\n  region: us-east-1\n  environment:\n    STAGE: prod-stage-test\nfunctions:\n  hello:\n    handler: handler.hello\n    environment:\n      HELLO: \"world ${self:provider.region}\"\n  goodbye:\n    handler: handler.goodbye\n    environment:\n      HELLO: \"cruel world\"\n      GOODBYE: \"world ${self:provider.region}\"\n```\n\nCalling `setEnv` would return:\n```javascript\n// All serverless env vars are initially loaded, but lambda env vars are\n// not prioritized and may override one another\nassert.deepEqual(process.env, {\n  ...\n  HELLO: 'cruel world',\n  GOODBYE: 'world us-east-1',\n  ...\n});\n// This is the name of the lambda declared in the \"functions\" block in the\n// serverless.yml\nconst envVars = ServerlessWrapper.setEnv('hello');\n\n// The \"hello\" lambda env vars have been loaded and take priority over all\n// others\nassert.deepEqual(process.env, {\n  ...\n  HELLO: 'world us-east-1',\n  GOODBYE: 'world us-east-1',\n  ...\n});\n```\n\n_Copyright (C) 2019 FireEye, Inc.
