Web Testing Infrastructure

Testing support for IREE's web platform port:

• Scripts to build tests with CMake/Emscripten
• HTML/JS for displaying individual tests and test suites
• Scripting to parse the list of tests provided by ctest into the format expected by the HTML/JS test suite runner

Quickstart

1. Install IREE's host tools (e.g. by building the install target with CMake)
2. Install the Emscripten SDK by following these directions
3. Initialize your Emscripten environment (e.g. run emsdk_env.bat)
4. From this directory, run bash ./build_sample.sh [path to install] && bash ./serve_sample.sh
5. Open the localhost address linked in the script output

Implementation Details

• Our tests (and benchmarks) generate binary files that when executed run tests then return an exit code
• When compiling for the web using Emscripten, each binary target produces a .js and a .wasm file
• Running an Emscripten-produced binary on a webpage requires just defining the Module object and importing the .js
• The test-runner.html webpage runs an individual test, based on URL parameters
• ctest --show-only=json-v1 outputs a JSON file enumerating all tests and their properties (working directory, required files, arguments, etc.). The parse_test_list.py script parses this file into a list of HTML elements linking to the test runner webpage with properties set
• The index_template.html webpage absorbs that list of hyperlinks and runs them in an <iframe>
