test(common): extend existing tests for better coverage

[pengfeixx]

Add test cases for CSyntaxHighlighter, Settings, Utils, FindBar, JumpLineBar, LineBar and Tabbar.

Log: 扩充common和controls模块现有测试用例
Influence: 提升Settings、Utils、Tabbar等类的函数覆盖率

Summary by Sourcery

Extend unit test coverage for common utilities, settings, syntax highlighting, and controls components.

Tests:

• Add coverage for multiple Utils functions including DLL loading, hashing, library path resolution, share-dir checks, text wrapping, and floating message display.
• Expand Tabbar tests to cover navigation, tab visibility actions, context menu event filtering, size-mode change handling, and translation strings.
• Increase Settings tests to exercise the custom backend lifecycle, save-path configuration, widget-creation lambdas, and key-sequence handling dialog logic.
• Augment CSyntaxHighlighter tests to verify invalid-character highlighting configuration paths.
• Add FindBar tests for switching to the replace bar and retrieving the current search text.
• Add LineBar and JumpLineBar tests to cover size-mode change reactions and line-count management.

Reviewer's Guide

This PR extends unit test coverage for several common and controls components (Utils, Tabbar, Settings, CSyntaxHighlighter, FindBar, LineBar, JumpLineBar) by deleting obsolete commented‑out tests and adding new, executable tests that exercise previously uncovered branches, lambdas, and helper functions without changing production code.

File-Level Changes

Change	Details	Files
Expand Utils unit tests to cover previously untested helper functions and edge paths.	Remove legacy, commented-out tests for detectEncode, codecConfidenceForData, and isShareDirAndReadOnly to reduce noise. Add executable tests for loadCustomDLL, getStringMD5Hash, libPath, and isShareDirAndReadOnly that validate behavior without relying on stubs. Add multiple lineFeed tests to cover single-row, multi-row, and negative-row branches. Add sendFloatMessageFixedFont test that exercises DFloatingMessage creation and the internal count_if lambda over repeated calls.	tests/src/common/ut_utils.cpp
Increase Tabbar test coverage, focusing on navigation, context-menu lambdas, constructor connections, and translation paths.	Remove old commented-out tests for openFilesInWindow, addTabWithIndex, updateTab, previousTab, and eventFilter. Add previousTab test that exercises index decrement and wrap-around behavior. Add showTabs test that checks enabling/disabling of close-left/right actions based on current index and tab count. Add eventFilter test that stubs tabAt and QMenu::exec to build the tab context menu, verify actions, and trigger all connected lambdas. Add constructor lambda test by toggling DGuiApplicationHelper::sizeMode and ensuring Tabbar reacts without crashing. Add explicit tr() tests to exercise Q_OBJECT-generated translations for common strings.	tests/src/controls/ut_tabbar.cpp
Extend Settings-related tests to cover CustemBackend, Settings lifecycle, and UI-handler lambdas for several options.	Add CustemBackend test that constructs a backend with a temporary config file, writes with doSetOption, flushes with doSync, queries keys, and reads via getOption, then deletes the backend. Add round-trip tests for Settings::setSavePathId and getSavePathId. Add explicit Settings destructor test via new/delete to cover non-singleton destruction path. Add createSavingPathWgt test that obtains a real DSettingsOption, builds the widget, and triggers the option valueChanged lambda. Add createFontComBoBoxHandle test that builds a combo box for a DSettingsOption and triggers both the option valueChanged lambda and the comboBox currentTextChanged lambda. Introduce NoLoopDDialog subclass plus stubbing for Settings::createDialog and add createKeySequenceEditHandle test that emits KeySequenceEdit::editingFinished to exercise its lambda without running a nested event loop.	tests/src/common/ut_setting.cpp
Add CSyntaxHighlighter tests to exercise invalid-character highlighting toggles.	Extend fixture tests to call setInvalidCharHighlight(true) and verify m_bInvalidCharHighlight and m_bHighlight are set. Add a complementary test with setInvalidCharHighlight(false) to confirm flags are cleared appropriately.	tests/src/common/ut_csyntaxhighlighter.cpp
Improve FindBar coverage for switch-to-replace behavior and current search text retrieval.	Add handleSwitchToReplace test that connects to sigSwitchToReplaceBar, invokes the handler, and asserts the signal is emitted. Add getCurrentSearchText test that checks the default empty state and then sets text in m_editLine->lineEdit to verify correct retrieval.	tests/src/controls/ut_findbar.cpp
Extend LineBar and JumpLineBar tests to cover size-mode reaction and line-count tracking.	Add LineBar constructor lambda test that toggles DGuiApplicationHelper::sizeMode to exercise the connected sizeModeChanged handler. Add JumpLineBar getLineCount test that calls activeInput and verifies the stored line count via getLineCount.	tests/src/controls/ut_linebar.cpp tests/src/controls/ut_jumplinebar.cpp

★ 总体评分：90分

■ 【总体评价】

代码新增了大量单元测试以提升覆盖率，但存在少量复制粘贴错误和脚本健壮性问题。
逻辑基本正确且无安全漏洞，因重复宏定义和rm命令缺乏容错各扣5分。

■ 【详细分析】

• 1.语法逻辑（基本正确）✓

代码整体语法正确，能够正常编译。新增的测试用例逻辑清晰，如 ut_setting.cpp 中通过重写 DDialog::exec() 避免事件循环崩溃的设计很巧妙。但 test-prj-running.sh 中取消了 rm -r 命令的注释，如果目录不存在会导致脚本报错并可能中断执行。
潜在问题：test-prj-running.sh 中的 rm -r $builddir 在首次运行或目录被清理后再次运行时，会因为目录不存在而执行失败。
建议：将 rm -r 修改为 rm -rf 以增加脚本的健壮性。

• 2.代码质量（良好）✓

测试代码整体结构清晰，注释完整，命名规范。但在 ut_linebar.cpp 中，DGUI_USE_NAMESPACE 宏被连续定义了三次，这明显是复制粘贴引入的冗余代码。
潜在问题：ut_linebar.cpp 中存在重复的宏定义，影响代码整洁度。
建议：删除 ut_linebar.cpp 中多余的 DGUI_USE_NAMESPACE 宏，保留一个即可。

• 3.代码性能（无性能问题）✓

测试代码主要关注功能覆盖，不涉及高并发或复杂算法，性能表现良好。test-prj-running.sh 中的 make -j8 充分利用了多核编译，符合常规构建流程。
建议：无需特别优化。

• 4.代码安全（存在0个安全漏洞）✓

漏洞对比统计：新增漏洞 0 个，减少漏洞 0 个，持平 0 个
本次提交为单元测试和构建脚本的更新，未引入任何安全漏洞。虽然 test-prj-running.sh 中使用了 rm 命令，但由于操作的是固定的相对路径目录且在测试环境中运行，不构成安全威胁。

• 建议：无需修复。
