Validating Android Unit Test Framework Implementation in PaddleOCR

This test suite demonstrates basic unit testing capabilities for the PaddleOCR Android demo application. It includes a fundamental JUnit test case that validates basic arithmetic operations, serving as a template for more complex OCR-related tests.

Test Coverage Overview

The test coverage currently focuses on basic arithmetic validation as a proof-of-concept. While minimal, it establishes the testing infrastructure for the Android OCR implementation.

Basic arithmetic operation testing
JUnit assertion framework usage
Local development machine execution verification

Implementation Analysis

The testing approach utilizes JUnit 4 framework for Android unit testing. The implementation demonstrates a straightforward test method structure with the @Test annotation and assertEquals assertion pattern.

Standard JUnit test class structure
Single method test case implementation
Basic assertion usage for equality checking

Technical Details

Testing infrastructure includes:

JUnit 4 testing framework
Android testing tools integration
Local development machine test execution environment
Standard Android project test directory structure

Best Practices Demonstrated

The test implementation showcases fundamental unit testing practices in an Android context. While simple, it establishes a foundation for more comprehensive OCR testing.

Clear test method naming conventions
Standard test class organization
Basic assertion pattern implementation
Test documentation inclusion
