Running the Fuchsia unit tests locally

These instructions assume you have set $FUCHSIA_DIR to your Fuchsia checkout and $ENGINE_DIR to the src/ folder of your Engine checkout. For example for zsh, add these lines to your ~/.zprofile:

export FUCHSIA_DIR=~/fuchsia
export ENGINE_DIR=~/engine/src
  1. In a separate terminal, start a Fuchsia package server:
cd "$FUCHSIA_DIR"
fx serve
  1. Run the unit tests:
$ENGINE_DIR/flutter/tools/fuchsia/devshell/run_unit_tests.sh

  • Pass --unopt to turn off C++ compiler optimizations.

  • Pass --count N to do N test runs. Useful for testing for flakes.

  • Pass --goma to accelerate the build if you're a Googler.

  • Pass --package-filter to run a specific test package instead of all the test packages. For example:

    $ENGINE_DIR/flutter/tools/fuchsia/devshell/run_unit_tests.sh --package-filter flow_tests-0.far

  • Pass --gtest-filter to run specific tests from the test package instead of all the tests. For example:

    $ENGINE_DIR/flutter/tools/fuchsia/devshell/run_unit_tests.sh --package-filter flutter_runner_tests-0.far --gtest-filter "*FlatlandConnection*"
