perfetto: refactor test code to consolidate pattern

With several types of testing now present, a clear pattern has been
established in how test code for end to end tests should be written.
This pattern involves spinning up service and producer, setting up a
test-specific trace config and then defining an intricate set of
checkpoints and RunUntilCheckpoint calls.

All of this code is duplicated and this will only get worse as we add
more benchmarks and tests to the codebase. Moreover, the
complex-appearance of the code hides the true simplicity within.

Refactor all the duplicated code into a helper file and call the
functions in this class from the four other cases where they are used
(integration test, fuzzer, benchmark and CTS).

Perfetto - Performance instrumentation and logging for POSIX platforms

This project is meant to be built both as part of the Android tree and from a standalone checkout

For internal docs see this page

Supported platforms

Android is the platform targeted in the first milestones. Right now Linux desktop and OSX are maintained best-effort.

Contributing

This project uses Android AOSP Gerrit for code reviews and uses the Google C++ style. Currently targets -std=c++11.

You can use both git cl upload from Chromium depot tools or Android repo to upload patches.

git cl is quite convenient as it supports code auto-formatting via git cl format.

See https://source.android.com/source/contributing for more details about external contributions and CLA signing.

Build instructions

See docs/build_instructions.md

Running Perfetto

See docs/running_perfetto.md

Continuous integration

Continuous build and test coverage is available at perfetto-ci.appspot.com. Trybots: CLs uploaded to gerrit are automatically submitted to TravisCI within one minute and made available on the CI page above. The relevant code lives in the infra/ directory.

Run tests

On the host (Linux / OSX)

$ tools/ninja -C out/default (tracing_unittests | tracing_benchmarks)
$ out/default/tracing_unittests --gtest_help

On Android

Either connect a device in ADB mode or use the bundled emulator.

To start the emulator:
$ tools/run_android_emulator (arm | arm64) &

To run the tests (either on the emulator or physical device):
$ tools/run_android_test out/default tracing_unittests
