Testing Selenium WebDriver Integration in Capybara

This test suite validates the Selenium WebDriver integration with Capybara, focusing on driver initialization and error handling. It ensures proper browser instantiation and verifies failure scenarios for robust testing implementations.

Test Coverage Overview

The test coverage focuses on the fundamental Selenium WebDriver initialization within Capybara’s driver implementation. It validates browser instance creation and deliberately triggers a failure condition to verify proper error handling.

Browser initialization testing
Driver configuration validation
Error state verification
Environment-specific browser selection

Implementation Analysis

The testing approach employs RSpec’s describe and it blocks to structure the Selenium driver tests. It utilizes environment variables for browser configuration flexibility and implements explicit failure scenarios to validate error handling behavior.
