Testing Continue Tag Error Handling in Shopify/liquid

This test suite validates the behavior of Liquid’s continue tag implementation in isolation. It specifically focuses on edge case handling when the continue tag is used outside of expected block contexts.

Test Coverage Overview

The test suite examines the error handling capabilities of Liquid’s continue tag implementation.

Key areas covered:

Edge case testing for continue tag usage outside block contexts
Verification of graceful error handling
Empty string output validation

Implementation Analysis

The testing approach utilizes Minitest framework to verify continue tag behavior in isolation. The test implements a straightforward pattern of setting up test conditions with empty assigns, defining markup with a continue tag, and asserting the expected empty string output.

Technical implementation details:

Uses assert_template_result for verification
Implements isolated tag testing methodology
Focuses on single-case validation

Technical Details

Testing infrastructure includes:

Minitest as the testing framework
Liquid module inclusion for template processing
Custom test helper utilities
Template result assertion methods

Best Practices Demonstrated

The test demonstrates several quality testing practices including isolation of test cases, clear test naming conventions, and explicit expected result definition. The code organization follows Ruby testing conventions with proper setup and assertion structure.

Notable practices:

Clear test method naming
Isolated test case design
Explicit variable declarations
Single responsibility principle in test cases
