Remove commented-out duplicate code in YGMeasureTest (#1927)

Summary: Remove three commented-out YGNodeSetMeasureFunc calls in tests/YGMeasureTest.cpp that are exact duplicates of the active calls on adjacent lines.

All three were introduced in commit fbd332d (2017-12-19) and left behind when the active lines were later updated by other authors. Each commented-out line sits directly next to its active duplicate:

Line 248 (commented) / line 249 (active)
Line 337 (commented) / line 336 (active)
Line 376 (commented) / line 377 (active)

Pull Request resolved: https://github.com/facebook/yoga/pull/1927

Test Plan:

No behavioral changes — only removes dead commented-out code
The active YGNodeSetMeasureFunc calls remain unchanged

Yoga

Yoga is an embeddable and performant flexbox layout engine with bindings for multiple languages.

Building

Yoga’s main implementation targets C++ 20 with accompanying build logic in CMake. A wrapper is provided to build the main library and run unit tests.

./unit_tests <Debug|Release>

While not required, this script will use ninja if it is installed for faster builds.

Yoga is additionally part of the vcpkg collection of ports maintained by Microsoft and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.

Adding Tests

Many of Yoga’s tests are automatically generated, using HTML fixtures describing node structure. These are rendered in Chrome to generate an expected layout result for the tree. New fixtures can be added to gentest/fixtures.

<div id="my_test" style="width: 100px; height: 100px; align-items: center;">
  <div style="width: 50px; height: 50px;"></div>
</div>

To generate new tests from added fixtures:

Ensure you have yarn classic installed.
Run yarn install to install dependencies for the test generator.
Run yarn gentest in the yoga directory.

Debugging

Yoga provides a VSCode “launch.json” configuration which allows debugging unit tests. Simply add your breakpoints, and run “Debug C++ Unit tests (lldb)” (or “Debug C++ Unit tests (vsdbg)” on Windows).
