IFT Client Tests

This is the repository for a test suite for clients which claim to conform to the W3C Incremental Font Transfer specification, developed by the W3C Web Fonts working group.

Setup

This repository pulls in a copy of the specification to check test coverage via git submodules, so you will need to run:

git submodule init
git submodule update

To initialize the repository.

Test Coverage Reports

Run

make all

To generate test and test plan coverage reports (test-coverage-report.txt and test-plan-coverage-report.txt) that specify which specification client conformance statements are not covered.

Generate Client Tests

The test cases here are generated by the Python scripts in the generators directory.

• ClientTestCaseGenerator.py

The scripts are dependent on the following package:

• FontTools https://github.com/behdad/fonttools

To compile a particular test suite, simply run the relevant script:

>>> python ClientTestCaseGenerator.py

To generate the subsetted fonts files needed for these tests, you can run the following command:

For the fallback font:

>>>python makeSubsettedFont.py fallback

(this will generate a font file that substitutes the p glyph with fail and the f glyph with pass)

For the font that will be used as the source for the IFT:

>>>python makeSubsettedFont.py IFT

(this will generate a font file that substitutes the f glyph with fail and the p glyph with pass)

The fallback font can be used as-is and the IFT source font can be used with the IFT encoder (https://github.com/w3c/ift-encoder) to create an IFT font that is then modified by the conformance test generator scripts.
