NOTICE

Autometa is under construction. It is currently unstable, poorly documented and not production ready for most cases.

Check back soon.

The following libraries may be considered relatively stable, but may contain bugs or unclear errors

• Overloaded - Function and method overloads that are as pleasant to make as they are to use
• Bind Decorator - Binds the this keyword on a class method. Respectfully a fork of bind-decorator
• Status Codes - Object containing HTTP status codes and status messages, visible in the editor via as const

Autometa

Autometa is an early-development automation framework toolkit, which provides libraries to help automate the automation process on node with libraries to help bootstrap your node automation framework, for API or E2E testing.

Cucumber Runner

The Cucumber Runner lets you build and execute Cucumber style tests with alternative test runners. Currently supported are jest.

Initially inspired by jest-cucumber provides a customizable hybrid approach between cucumbers flat global steps and jest-cucumbers nested spec-like tests.

Dependency injection is supported to make initializing client classes needed to interface with your service or website simple and logic-free, with unique copies provided to each executing tests.

1import { Feature, Given, When, Then, Before } from "@autometa/runner";
2import { App } from "./my-app";
3import * as seedData from "./seed-data";
4
5Before("Seed the database", async ({ dbClient }: App) => {
6  await dbClient.seed(seedData);
7});
8Given("a user who wants to log in", () => {});
9When("a user submits their credentials", () => {});
10Then("a user sees their", () => {});
11
12// tests assembled automatically
13Feature("./my-feature.feature");

Steps can also be nested or groups to override higher level steps.

Dto Builder

Implementation of the Builder pattern that allows automatically generating builder classes from a DTO class prototype, with type-safe builder methods in place of DTO properties.

1import { dto, Builder } from '@autometa/dto-builder'
2export class UserDto {
3    id: number
4    username: string,
5    // default values, factories, dtos
6    @DTO.dto(AddressDto)
7    address: AddressDto
8    @DTO.date()
9    createdAt: Date
10}
11// or
12// avoid duplicating interface properties
13export class UserDto extends DTO<IUser> {}
14
15const UserDtoBuilder = Builder(UserDto);
16
17const user = new UserDtoBuilder().id(1).name('bob').build()
18
19// compilation error, 'first argument of "id" must be a number"
20 new UserDtoBuilder().id('1').name('bob').build()
21 // force it to pass a string
22 new UserDtoBuilder().id('1' as unknown as number).name('bob').build()
