To begin using Shortest, first install it as a development dependency in your project. You can choose your preferred package manager: npm, pnpm, or yarn. For example, using npm, you would run "npm install --save-dev shortest". Once installed, configure Shortest by creating a "shortest.config.ts" file in your project root. This configuration file is crucial for defining your testing environment. Within "shortest.config.ts", you must specify a "baseURL" for your application, the "testDir" where your test files will reside, and an "AnthropicAPIKey" for leveraging the AI capabilities. Ensure your Anthropic API key is securely managed, ideally through environment variables. For tests requiring GitHub authentication, Shortest supports two-factor authentication (2FA). To set this up, you'll need to obtain your OTP secret from GitHub. This secret should then be added to your environment variables, allowing Shortest to securely log in and interact with GitHub-protected resources during test execution. After configuration, you can start writing your tests in plain English within the specified test directory. Shortest's AI will interpret these natural language descriptions to automate browser interactions. The framework is built on Playwright, ensuring robust and reliable test execution. During test runs, Shortest automatically captures screenshots, storing them in a ".shortest/" directory. It is highly recommended to add this directory to your project's ".gitignore" file to prevent committing transient test artifacts. Additionally, Shortest offers lifecycle hooks for setting up and tearing down test environments, providing granular control over your test suite. Callback functions are also supported for custom assertions and advanced logic, enhancing the flexibility of your tests.
