+Getting ready to start.
+
+Before you start to hack on Observatory, follow the [instructions][build_sdk] to
+have a working environment in which you are able to build and test the Dart SDK.
+
+## Run existing tests
+Before hacking Observatory let's run the existing Observatory tests.
+We suggest to run all the test in __debug__ mode.
+
+First build the sdk in debug mode
+```
+$ ./tools/build.py --mode debug create_sdk
+```
+
+From the root of the sdk repository run:
+```
+$ ./tools/test.py -mdebug service
+```
+
+## Serve Observatory
+Observatory is built as part of building the sdk. Previously, it was recommended
+to run the Observatory using `pub serve` to avoid having to rebuild the sdk for
+each change to Observatory. However, `pub serve` was deprecated as part of the
+transition to Dart 2.0.
+
+[Issue #35678](https://github.com/dart-lang/sdk/issues/35678)
+tracks changes required to allow for `package:build_runner` to run Observatory
+without having to rebuild the sdk after each change.
+
+## Connect to a VM
+Start a Dart VM with the ``--observe`` flag (as explained in the
+[get started guide][observatory_get_started]) and connect your Observatory
+instance to that VM.
+
+Example script (file name ```clock.dart```):
+```dart
+import 'dart:async' show Timer, Duration;
+
+main() {
+ bool tick = true;
+ new Timer.periodic(const Duration(seconds: 1), (Timer t) {
+ print(tick ? 'tick' : 'tock');
+ tick = !tick;
+ });
+}
+```
+Start the script:
+```
+$ dart --disable-service-origin-check --observe clock.dart
+```
+
+## Code Reviews
+The development workflow of Dart (and Observatory) is based on code reviews.
+
+Follow the code review [instructions][code_review] to be able to successfully
+submit your code.
+
+The main reviewers for Observatory related CLs are:
+ - asiva
+ - bkonyi
+ - rmacnak
+
+## Write a new service test
+All the service tests are located in the ```tests/service``` folder.
+Test file names follow the convention ```<description>_test.dart```
+(e.g. ```a_brief_description_test.dart```).
+
+The test is generally structured in the following way.
+```dart
+import 'package:test/test.dart';
+
+main() {
+ // Some code that you need to test.
+ var a = 1 + 2;
+
+ // Some assertions to check the results.
+ expect(a, equal(3));
+}
+```
+See the official [test library][test_library] instructions;
+
+The ```test_helper.dart``` file expose some functions that allow to run a part
+of the code into another __VM__.
+
+To test synchronous operations:
+```dart
+import 'test_helper.dart';
+
+code() {
+ // Write the code you want to be execute into another VM.
+}
+
+var tests = [
+ // A series of tests that you want to run against the above code.
+ (Isolate isolate) async {
+ await isolate.reload();
+ // Use the isolate to communicate to the VM.
+ }
+];
+
+main(args) => runIsolateTestsSynchronous(args,
+ tests,
+ testeeConcurrent: code);
+```
+
+In order to test asynchronous operations:
+```dart
+import 'test_helper.dart';
+
+code() async {
+ // Write the asynchronous code you want to be execute into another VM.
+}
+
+var tests = [
+ // A series of tests that you want to run against the above code.
+ (Isolate isolate) async {
+ await isolate.reload();
+ // Use the isolate to communicate to the VM.
+ }
+];
+
+main(args) async => runIsolateTests(args,
+ tests,
+ testeeConcurrent: code);
+```
+
+Both ```runIsolateTests``` and ```runIsolateTestsSynchronous``` have the
+following named parameters:
+ - __testeeBefore__ (void()) a function that is going to be executed before
+the test
+ - __testeeConcurrent__ (void()) test that is going to be executed
+ - __pause_on_start__ (bool, default: false) pause the Isolate before the first
+instruction
+ - __pause_on_exit__ (bool, default: false) pause the Isolate after the last
+instruction
+ - __pause_on_unhandled_exceptions__ (bool, default: false) pause the Isolate at
+an unhandled exception
+ - __trace_service__ (bool, default: false) trace VM service requests
+ - __trace_compiler__ (bool, default: false) trace compiler operations
+ - __verbose_vm__ (bool, default: false) verbose logging
+
+
+Some common and reusable test are available from ```service_test_common.dart```:
+ - hasPausedFor
+ - hasStoppedAtBreakpoint
+ - hasStoppedWithUnhandledException
+ - hasStoppedAtExit
+ - hasPausedAtStartcode_review
+and utility functions:
+ - subscribeToStream
+ - cancelStreamSubscription
+ - asyncStepOver
+ - setBreakpointAtLine
+ - resumeIsolate
+ - resumeAndAwaitEvent
+ - resumeIsolateAndAwaitEvent
+ - stepOver
+ - getClassFromRootLib
+ - rootLibraryFieldValue
+
