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 --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*"
