api-test-lib

Overview

This framework is designed to automate API testing for multiple services, including GAP, SLB, SBS, and TimedBidding. It utilizes Playwright for creating requests and MySQL2 for querying the ViewCache Database.

Features

- Multi-Service Support: Tests can be written for GAP, SLB, SBS, and TimedBidding services.
- Playwright Integration: Leverages Playwright for robust and reliable API request handling.
- MySQL2 Database Queries: Utilizes MySQL2 to query the ViewCache Database for data validation.
- Modular Structure: Organized into separate folders for configurations, fixtures, resources, services, tests, and utilities.
- Fixture-Based Service Initialization: Services are initialized using Playwright fixtures, simplifying test setup and ensuring consistent environments.

Setup Instructions

1. Clone the Repository:
`bash
git clone git@github.com:globalauctionplatform/api-test-lib.git
`

2. Install Dependencies:
Navigate into the cloned directory and install required packages:
`bash
npm install
`

3. Configure Environment Variables:
- Copy the .env.example file to create a .env file:
`bash
cp .env.example .env
`
- Update the .env file with your actual environment variables (e.g., database credentials, service endpoints).

4. Run Tests:
Execute tests using the following command:
`bash
npm run test
`

Framework Architecture

$3

This structure organizes the framework into logical components:
1. The root directory handles configuration and project metadata.
2. fixtures/, resources/, and utils/: Provide reusable components like test data, payloads, utilities, and models.
3. services/: Encapsulates service-specific logic and endpoint definitions, as well as SQL query utility..
4. tests/: Contains test cases organized by feature or service.

$3

- .env: Contains environment-specific variables, such as API keys, base URLs, and database credentials. This file should not be committed to version control.
- .env.example: A template for .env that lists all required environment variables without sensitive values.
- api.config.ts: Configuration file for the API testing framework. It may include setup details like base URLs, authentication tokens, and global configurations.
- package.json: Defines dependencies, scripts, and metadata for the project.
- package-lock.json: Locks the dependency tree to ensure consistent installations across environments.
- README.md: Documentation for the framework, including setup instructions, usage examples, and file structure.

$3

- fixtures.ts: Contains reusable test data or setup logic like service classes that can be injected into the test scenarios.

$3

Contains JSON files with payloads used in API requests, for instance:
- auctionPayload.json: Sample payload for auction-related operations.

$3

Contains service classes and endpoint definitions:
- gap/
- AuctionApprovalEndpoint.ts: Defines methods for interacting with the auction approval endpoint (e.g., approving auctions).
- BidderRegistrationEndpoint.ts: Contains methods for bidder registration operations.
- GapService.ts: Initializes the GAP service and provides access to its endpoints.
- QueryHelper.ts: A utility file that likely contains helper functions for querying data or performing common tasks across services.
- slb/
- AuctionEndpoint.ts: Contains methods for auction-related operations in SLB (e.g., creating auctions).

$3

Contains test cases organized by feature or service:
- api/
- api.spec.ts: Covers end-to-end scenarios for SBSv2

$3

Utility functions and helpers used across the framework:
- DateUtils.ts: Provides utility functions for handling dates and times (e.g., formatting, calculating durations).
- DBConnector.ts: Handles database connections and queries using MySQL2.
- models/:
- Contains TypeScript models representing data structures used in requests or responses:
- AuctionApprovalData.ts: Model for auction approval data.

$3

Services encapsulate configuration and expose endpoints. Example structure:
`typescript
class FooService {
private baseUrl: string;
private headers: Record;
private apiContext: APIRequestContext;

public auctionApprovalEndpoint: AuctionApprovalEndpoint;
public bidderRegistrationEndpoint: BidderRegistrationEndpoint;

constructor(baseUrl: string, apiKey: string) {
this.baseUrl = baseUrl;
this.headers = {
'Authorization': Bearer ${apiKey},
'Content-Type': 'application/json'
};

this.apiContext = await request.newContext({
baseURL: this.baseUrl,
extraHTTPHeaders: this.headers
});

this.auctionApprovalEndpoint = new AuctionApprovalEndpoint(this.apiContext);
this.bidderRegistrationEndpoint = new BidderRegistrationEndpoint(this.apiContext);
}
}
`

$3

Endpoint classes contain specific API operations:
`typescript
class AuctionApprovalEndpoint {
constructor(private apiContext: APIRequestContext) {}

async createCustomer(payload: CustomerPayload): Promise {
return this.apiContext.post('/v1/auctions/approvals', {
data: payload
});
}
}
`

$3

Tests are located in the tests/ directory. Services like gapService and slbService are initialized using Playwright fixtures, allowing you to use them directly in tests without manual setup.

$3

`typescript
test.only('Create auction Standard QA Environment', async ({ slbService, gapService }) => {
// Use services here
const createAuctionResponse = await slbService.auctionEndpoint.createAuction(AuctionCreationData.fromAuctionDuration(3, 'hour'));
const atgAuctionId = await createAuctionResponse.auctionDetails.atgAuctionId;
expect(atgAuctionId).toBeTruthy();
});
`

$3

1. Separation of Concerns:
- Services handle configuration
- Endpoints focus on specific API operations
2. Reusability: Endpoint methods can be reused across test scenarios
3. Type Safety: Strong typing for both payloads and responses
4. Centralized Configuration: Base URL and headers managed in one place

$3

1. Add a new service folder in services/, like foo/
2. Create the service class following the FooService pattern
3. Create corresponding endpoints in services/foo/
4. Add the corresponding service entry in the fixtures/fixtures.ts
5. Add the reference to the service Fixture in every scenario that needs it for test files in tests//
6. Enjoy!

#### utils/DBConnector.ts
This module is responsible for configuring and managing the database connection. It provides a method to execute SQL queries:

- query(sql: string, params?: any[]): Executes a SQL query with optional parameters. This method is used throughout the framework to interact with the database.

#### utils/QueryHelper.ts
This utility class provides methods to query the database with retry logic for handling transient errors:

- retryOperation(operation: () => Promise): A private method that retries a given asynchronous operation up to MAX_RETRIES times with a delay of RETRY_DELAY_MS between attempts.
- getAuctionRecord(atgAuctionId: any): An example method that uses the retry logic to fetch an auction record from the database. This method is static and can be used across the framework.

#### Usage Example
`typescript
import { QueryHelper } from './utils/QueryHelper';

// Fetch an auction record with retry logic
const auctionRecord = await QueryHelper.getAuctionRecord('foo');
