Validating HTML Entity Transformation in uni-app Compiler Tests

This test suite validates the handling of HTML entities in the uni-app compiler’s transformation process. It ensures proper preservation and processing of special characters and spacing entities during component compilation.

Test Coverage Overview

The test suite focuses on entity preservation during compilation, specifically targeting HTML special characters and spacing entities.

Key areas covered include:

HTML special characters (<, >)
Spacing entities ( , , , )
Text component transformation

Implementation Analysis

The testing approach utilizes Jest’s describe/test pattern with custom assertion utilities. The implementation verifies entity handling within text components, ensuring the compiler maintains entity integrity during transformation.

Technical patterns include:

Custom assert utility integration
Template string comparison
Context object validation

Technical Details

Testing infrastructure includes:

Jest test framework
Custom testUtils assertion library
TypeScript implementation
Compiler transformation hooks
Entity preservation validation

Best Practices Demonstrated

The test implementation showcases strong testing practices through isolated component testing and explicit expected outputs. Notable practices include:

Explicit entity enumeration
Isolated transformation testing
Clear input/output validation
Context object verification
