Dear Libreoffice community,
I'm Manish Bera, working on the *"Improve Word Processor Test Coverage"*
project this summer under the mentorship of Jonathan Clark. The project
focuses on improving test coverage of Writer's legacy layout engine (
*sw/source/core*) using *lcov metrics* and *parseLayoutDump() assertions*.
Accomplishments
-
Set up a *dual-repo workflow*: MSVC on Windows for test development and
a lightweight GCC build in WSL2 (--enable-gcov, --disable-gui,
--without-java) for fast lcov coverage analysis.
-
Generated baseline *lcov reports* for entire sw/source/core/
-
Analyzed txtdrop.cxx and identified multiple untested code paths.
-
Added new CppUnit tests covering:
-
lcl_IsDropFlyInter Drop Caps/Fly frame intersection handling.
-
SwTextFrame::GetDropLen logic for *ASIAN* and *COMPLEX* scripts.
-
Vertical text Drop Caps layout calculations.
-
Submitted a patch, increasing the coverage of txtdrop.cxx to almost all
of testable lines and increasing the coverage to 10%.
Next Week
-
Review the first patch during my sync with my mentor.
-
Use lcov reports to identify the next high-value untested areas in core/text
and core/txtnode
Thank you!
Best regards,
Manish Bera
