fuchsia.web
- Fuchsia WebEngine and Runners
This directory contains code related to the
fuchsia.web
FIDL API.
Specifically, it contains the implementation of Fuchsia WebEngine and code
related to it, including the Runners that use it. Code in this
directory must not be used outside it and its subdirectories.
General information about Chromium on Fuchsia is here.
[TOC]
Code organization
Each of the following subdirectories contain code for a specific Fuchsia service:
./common
contains code shared by both WebEngine and Runners../runners
contains implementations of Fuchsiasys.runner
../runners/cast
Enables the Fuchsia system to launch Cast applications.
./shell
contains WebEngineShell, a simple wrapper for launching URLs in WebEngine from the command line../webengine
contains the WebEngine implementation. WebEngine is an implementation offuchsia.web
that enables Fuchsia Components to render web content using Chrome's Content layer../webinstance_host
contains code for WebEngine clients to directly instantiate a WebInstance Component (web_instance.cm
) using the WebEngine package.
Test code
There are 3 major types of tests within this directory:
- Unit tests: Exercise a single class in isolation, allowing full control over the external environment of this class.
- Browser tests: Spawn a full browser process and its child processes. The test code is run inside the browser process, allowing for full access to the browser code - but not other processes.
- Integration tests: Exercise the published FIDL API of a Fuchsia Component. For
instance,
//fuchsia_web/webengine:web_engine_integration_tests
make use of the//fuchsia_web/webengine:web_engine
component. The test code runs in a separate process in a separate Fuchsia Component, allowing only access to the published API of the component under test.
Integration tests are more resource-intensive than browser tests, which are in turn more expensive than unit tests. Therefore, when writing new tests, it is preferred to write unit tests over browser tests over integration tests.
As a general rule, test-only code should live in the same directory as the code
under test with an explicit file name, either fake_*
, test_*
,
*_unittest.cc
, *_ browsertest.cc
or *_integration_test.cc
.
Test code that is shared across Components should live in a dedicated ``test
directory. For example, the //fuchsia_web/webengine/test
directory, which
contains code shared by all browser tests, and
//fuchsia_web/common/test
, which contains code shared by tests for both
WebEngine and Runners.
