Add comprehensive test coverage for uncovered utility, protocol, and codec classes

[Copilot]

Generated test suites for 7 previously untested classes, adding 164 test methods with full coverage of public APIs, edge cases, and concurrency scenarios.

Classes Covered

• ByteUtils (53 tests): Byte conversions, array operations, bit manipulation, encoding/decoding with null/empty/overflow edge cases
• JsonRpcRequest (31 tests): Request construction, thread-safe ID generation, equality/hash contracts, generic type support
• TopicTools (34 tests): Event topic encoding for integers, booleans, addresses, strings, bytes; validation and multi-crypto support
• SystemInformation (20 tests): JVM properties, system information, cryptographic curve detection
• ThreadPoolService (13 tests): Lifecycle management, concurrent execution, shutdown behavior, rejection policies
• LinuxSecureRandom (9 tests): Platform-aware testing with graceful skips on non-Linux systems
• SecureRandomUtils (4 tests): Secure random generation, Android detection, singleton consistency

Test Characteristics

All tests use JUnit 4 + Mockito with @Before initialization, covering:

• Normal flow and exception paths
• Boundary values (min/max, empty, null)
• Concurrent execution where applicable
• Platform-specific behavior

Example test pattern:

@Before
public void setUp() {
    cryptoSuite = new CryptoSuite(CryptoType.ECDSA_TYPE);
    topicTools = new TopicTools(cryptoSuite);
}

@Test
public void testIntegerToTopicWithZero() {
    String result = topicTools.integerToTopic(BigInteger.ZERO);
    Assert.assertEquals(66, result.length());
    Assert.assertTrue(result.matches("0x0{64}"));
}

@Test(expected = IllegalArgumentException.class)
public void testByteNToTopicWithTooLargeArray() {
    topicTools.byteNToTopic(new byte[33]);
}

All 164 tests pass. CodeQL reports 0 vulnerabilities.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• invalid.host.name.xyz
  • Triggering command: /usr/lib/jvm/temurin-11-jdk-amd64/bin/java -Dorg.gradle.native=false -javaagent:build/tmp/expandedArchives/org.jacoco.agent-0.8.6.jar_a26f6511a7813217be4cd6439d66563b/jacocoagent.jar=destfile=build/jacoco/test.exec,append=true,inclnolocationclasses=false,dumponexit=true,output=file,jmx=false @/tmp/gradle-worker-classpath11154634470715769919txt -Xmx512m -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -ea worker.org.gradle.process.internal.worker.GradleWorkerMain 'Gradle Test Executor 1' (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

分析当前类以及当前package的测试覆盖率，为未覆盖的方法生成测试用例，要求： 1. 使用 JUnit和Mockito 2. 覆盖所有公共方法 3. 包含正常流程、异常情况和边界值测试 4. 使用 @beforeeach 初始化测试数据

CONVERSATION SUMMARY

TITLE: Generate Test Cases for Uncovered Methods in Current Class/Package

USER INTENT: The user wants to analyze test coverage for the current class and package, then generate test cases for uncovered methods using JUnit and Mockito.

TASK DESCRIPTION:

• Analyze test coverage for the current class and its package
• Generate comprehensive test cases for methods that lack coverage
• Requirements include:
  • Use JUnit and Mockito frameworks
  • Cover all public methods
  • Include normal flow, exception cases, and boundary value tests
  • Use @beforeeach for test data initialization

EXISTING:

• No conversation history or existing implementation details provided
• The task appears to be at the initial request stage

PENDING:

• Identify the target class/package for coverage analysis
• Analyze current test coverage metrics
• Identify uncovered public methods
• Generate test cases with:
  • Normal/happy path scenarios
  • Exception handling tests
  • Boundary value tests
  • Proper use of Mockito for mocking dependencies
  • @beforeeach setup methods for test data initialization

CODE STATE:

• No specific files or code have been referenced yet
• Awaiting identification of target class/package

RELEVANT CODE/DOCUMENTATION SNIPPETS:
None provided in the conversation.

OTHER NOTES:

• The request is in Chinese but clearly specifies technical requirements
• This appears to be a test-driven development or code quality improvement task
• The user expects comprehensive test coverage following best practices
• Standard JUnit 5 and Mockito conventions should be followed
