From 3d45aae02633c94dc226d134683e1d84145ea186 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 20 Jan 2026 02:49:03 +0000 Subject: [PATCH 1/2] Improve project infrastructure: tests, docs, error handling, and architecture Major improvements to project quality and maintainability: Tests & Quality: - Add JUnit 5, Mockito, AssertJ test dependencies - Create comprehensive unit tests for DatabaseManager, DynamicTable, ItemBuilder - Add test configuration with proper reporting Documentation: - Create detailed dynamic-database.md guide with examples and best practices - Create comprehensive gui-conditions.md guide for GUI API - Add extensive JavaDoc to public API classes (DatabaseManager, DynamicDatabase) Error Handling: - Introduce exception hierarchy for better error diagnostics - Add DatabaseConnectionException for connection failures - Add QueryExecutionException with SQL context - Add EntityMappingException for ORM errors - Add ConfigurationException for config validation - Update all database code to use specific exceptions Architecture Improvements: - Refactor ItemBuilder to support dependency injection for ColorUtil - Extract HikariConfigBuilder from DatabaseManager for better separation - Add DatabaseMetrics class for connection pool monitoring - Maintain backward compatibility with default constructors This update significantly improves code quality, testability, documentation, and error handling without breaking existing functionality. --- build.gradle | 20 + docs/dynamic-database.md | 422 ++++++++++ docs/gui-conditions.md | 765 ++++++++++++++++++ .../api/database/ConfigurationException.java | 15 + .../nextlib/api/database/DatabaseClient.java | 8 +- .../database/DatabaseConnectionException.java | 19 + .../nextlib/api/database/DatabaseManager.java | 176 ++-- .../nextlib/api/database/DatabaseMetrics.java | 174 ++++ .../api/database/EntityMappingException.java | 28 + .../api/database/HikariConfigBuilder.java | 125 +++ .../api/database/QueryExecutionException.java | 23 + .../api/database/dynamic/DynamicDatabase.java | 83 +- .../api/database/dynamic/EntityMetadata.java | 9 +- .../chi2l3s/nextlib/api/item/ItemBuilder.java | 131 ++- .../api/database/DatabaseManagerTest.java | 180 +++++ .../database/dynamic/DynamicTableTest.java | 202 +++++ .../nextlib/api/item/ItemBuilderTest.java | 89 ++ 17 files changed, 2373 insertions(+), 96 deletions(-) create mode 100644 docs/dynamic-database.md create mode 100644 docs/gui-conditions.md create mode 100644 src/main/java/io/github/chi2l3s/nextlib/api/database/ConfigurationException.java create mode 100644 src/main/java/io/github/chi2l3s/nextlib/api/database/DatabaseConnectionException.java create mode 100644 src/main/java/io/github/chi2l3s/nextlib/api/database/DatabaseMetrics.java create mode 100644 src/main/java/io/github/chi2l3s/nextlib/api/database/EntityMappingException.java create mode 100644 src/main/java/io/github/chi2l3s/nextlib/api/database/HikariConfigBuilder.java create mode 100644 src/main/java/io/github/chi2l3s/nextlib/api/database/QueryExecutionException.java create mode 100644 src/test/java/io/github/chi2l3s/nextlib/api/database/DatabaseManagerTest.java create mode 100644 src/test/java/io/github/chi2l3s/nextlib/api/database/dynamic/DynamicTableTest.java create mode 100644 src/test/java/io/github/chi2l3s/nextlib/api/item/ItemBuilderTest.java diff --git a/build.gradle b/build.gradle index e1e9148..846cef8 100644 --- a/build.gradle +++ b/build.gradle @@ -25,6 +25,18 @@ dependencies { implementation 'org.yaml:snakeyaml:2.2' implementation 'com.squareup:javapoet:1.13.0' implementation 'com.zaxxer:HikariCP:7.0.2' + + // Testing dependencies + testImplementation 'org.junit.jupiter:junit-jupiter-api:5.10.1' + testImplementation 'org.junit.jupiter:junit-jupiter-params:5.10.1' + testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.10.1' + testImplementation 'org.mockito:mockito-core:5.8.0' + testImplementation 'org.mockito:mockito-junit-jupiter:5.8.0' + testImplementation 'org.assertj:assertj-core:3.25.1' + testImplementation 'com.h2database:h2:2.2.224' + testImplementation "com.destroystokyo.paper:paper-api:1.16.5-R0.1-SNAPSHOT" + testCompileOnly "org.projectlombok:lombok:1.18.34" + testAnnotationProcessor "org.projectlombok:lombok:1.18.34" } publishing { @@ -74,3 +86,11 @@ processResources { expand props } } + +test { + useJUnitPlatform() + testLogging { + events "passed", "skipped", "failed" + exceptionFormat "full" + } +} diff --git a/docs/dynamic-database.md b/docs/dynamic-database.md new file mode 100644 index 0000000..56069a3 --- /dev/null +++ b/docs/dynamic-database.md @@ -0,0 +1,422 @@ +# Динамическая база данных - Руководство + +## Обзор + +Модуль динамической базы данных NextLib предоставляет легковесную ORM-систему для работы с реляционными базами данных.
