Integration tests

Integration tests are written against client-facing FIDL services exposed by Modular. They make use of the Modular Test Harness.

Writing a new test

The easiest way to get started is to make a copy of an existing test. Be sure to:

1. Add an entry in BUILD.gn to build the new test executable()
2. Create a .cmx meta file in meta/
3. Add both the executable binary to the test_package() declaration in BUILD.gn

Running tests

Run the following commands to build & run your tests:

fx set core.x64 --with //src/modular/tests
fx build

NOTE: You only need to run fx set once.

Running all tests

fx run-test modular_integration_tests

Running one test

Add the following to the above command:

-- --gtest_filter="{ClassName}.{TestName}"
