+The majority of this document is targeting the Firefox developer that would like to understand TPS and/or write TPS tests. If you'd like to simply run TPS, see the [How to run TPS](#how-to-run-tps) section.
+
+## What is TPS
+TPS is a test automation framework for Firefox Sync. TPS takes in test configuration as JavaScript files defined in [a configuration file](#test-format) and runs all tests in sequence.
+
+Each TPS test is made of one or more [phases](#phases) that each have their own assertions and run in sequence. If **any** phase fails, then the test fails and the remaining phases are not run. However, other tests will still run.
+
+## Why TPS exists
+TPS runs against the real Mozilla Accounts server and Sync servers and thus is a good way to test Firefox Sync end-to-end without mocking the servers.
+
+## Architecture

+
+
+### Phases
+Each Phase is mapped to a Firefox profile, phases may re-use profiles if they are mapped to them, see [the phases object](#the-phases-object) for details on the mapping. All phases are signed in to the same Mozilla Account.
+#### Example
+For example, a simple test that defines two phases, one that uploads bookmarks and another that downloads them can be described as follows, see the section on [Test Format](#test-format) for details on the format of the tests.
+```js
+EnableEngines(["bookmarks"]); // Enables the bookmark engine across all profiles(phases) that this test runs
+
+/*
+ * The list of phases mapped to their corresponding profiles.  The object
+ * here must be in JSON format as it will get parsed by the Python
+ * testrunner. It is parsed by the YAML package, so it relatively flexible.
+ */
+var phases = {
+  phase1: "profile1",
+  phase2: "profile2",
+};
+
+// the initial list of bookmarks to add to the browser
+var bookmarksInitial = {
+  menu: [
+    { folder: "foldera" },
+    { folder: "folderb" },
+  ],
+
+  "menu/foldera": [{ uri: "http://www.cnn.com", title: "CNN" }], // One bookmark in menu/foldera pointing to CNN
+  "menu/folderb": [{ uri: "http://www.apple.com", title: "Apple"}], // One bookmark in menu/folderb pointing to apple
+};
+
+// Add bookmarks to profile1 and sync.
+Phase("phase1", [
+  [Bookmarks.add, bookmarksInitial],
+  [Bookmarks.verify, bookmarksInitial],
+  [Sync],
+  [Bookmarks.verify, bookmarksInitial],
+]);
+
+
+// Sync, then verify that bookmarks added by phase 1 are present.
+Phase("phase2", [
+  [Sync],
+  [Bookmarks.verify, bookmarksInitial],
+]);
+```
+
+### The TPS Extension
+When the Firefox profile representing the phase loads, it first installs an [extension](https://searchfox.org/mozilla-central/source/services/sync/tps/extensions/tps). The extension is what executes the tests by instructing Firefox and reading from Firefox to assert that Sync is working properly.
+
+The test files execute in the extension, and the [extension defines all the functions that the test files may use](https://searchfox.org/mozilla-central/source/services/sync/tps/extensions/tps/resource/tps.sys.mjs). For instance, in the above [example](#example) the `Phase` function is defined [here](https://searchfox.org/mozilla-central/rev/1f27a4022f9f1269d897526c1c892a57743e650c/services/sync/tps/extensions/tps/resource/tps.sys.mjs#1234)
+
+## Test Format
+### Test group configuration
+The tests are referenced by a `json` file that references all the tests TPS will run. By default TPS will run the configuration in [`services/sync/tests/tps/all_tests.json`](https://searchfox.org/mozilla-central/source/services/sync/tests/tps/all_tests.json).
+The test group configuration is a `json` object with one key named `tests` that is itself a `json` object. The `tests` object has a key for every test to run, and the key should be the name of the [test file](#test-files). The value for each test file is the empty object `{}` if the test should run, or
+`{"disabled": "Bug <BUG NUMBER>"}` where `<BUG NUMBER>` is a Bugzilla bug number referencing why the test was disabled.
+
+
+### Test Files
+#### The phases object
+Test Files are JavaScript files that will be run by the TPS extension once the Firefox profile is loaded. However, before that is done the TPS framework will load the first object defined in test file as `yaml`. In other words, for the following example:
+```js
+var phases = {
+    phase1: "profile1",
+    phase2: "profile2",
+    phase3: "profile1", // phase 1 and 3 reuse the same profile, "profile1"
+}
+
+// ... rest of the test file
+```
+The inside of the curly brackets will be parsed as yaml to identify the profiles that TPS will run and map each phase to a profile. In the example above, `phase1` and `phase3` reuse the same profile, but `phase2` uses it's own profile. The rest of the file is regular JavaScript that will be loaded in the [TPS Extension](#the-tps-extension).
+#### Test File Capabilities
+The TPS Extension exports a set of functions and objects that test files may use. See the [`tps.sys.mjs`](https://searchfox.org/mozilla-central/source/services/sync/tps/extensions/tps/resource/tps.sys.mjs) for up-to-date details, the following is the list of export capabilities as of April 10th, 2024:
+##### Enabling Sync Engines
+To enable sync engines, which you should do before executing a test that depends on an engine, use the `EnableEngines` function. The function takes an array of strings representing the engine names. Eg:
+```js
+EnableEngines(["bookmarks", "history"]);
+```
+##### Start a phase
+Phases are run on their assigned profiles profiles in the order they are declared in [the phases object](#the-phases-object). To define what a phase does use the `Phase` function that takes in a phase name as the first argument - **this should be the same name defined in the [phases object](#the-phases-object)** - and a 2D array of actions as a second argument. Each action array in the 2D is run in sequence. The inner array defines what the action is, and any arguments to that action. For example:
+```js
+Phase("phase1", [[Sync], [Bookmarks.add, bookmarkInitial]]);
+```
+
+Note that the example assumes that the phases object and `bookmarkInitial` are defined in test file.
+
+In the above example:
+- `"phase1"` is the name of the phase, which should match exactly the phase name as defined in [the phases object](#the-phases-object).
+- The 2D array passed as the second argument has:
+  - `[Sync]` as its first array which means that the phase will first Sync
+  - `[Bookmarks.add, bookmarkInitial]` as its second member which means that after the Sync, a Bookmarks.add operation will run, and it will add the `bookmarkInitial`.
+
+##### Actions
+Actions are run inside phases as arguments to the [`Phase`](#start-a-phase) function.
+###### General Actions
+There are few general actions that aren't tied to a data type:
+- `Sync`: Will trigger a sync
+- `Login`: Logs in to Mozilla Account. **You shouldn't need to do this in most cases as it is done automatically**
+- `WipeServer`: Will wipe all data from the server
+- `EnsureTracking`: Will wait until sync tracking has started. **You shouldn't need to do this in most cases**
+
+###### Data Type specific Actions
+
+Some actions are supported for individual data types. Those actions are triggered by using `<DataType>.<Action>`. The following is a list of all possible `<DataType>` values:

+
+## Writing new TPS tests
+To write new TPS tests follow the following instructions:
+1. Create a new `.js` file in `services/sync/tests/tps` named `test_<my_test_name>.js`
+2. Link to the file in the `services/sync/tests/tps/all_tests.json`
+3. Follow the format described in [Test Files](#test-files)
+4. Make sure to test the file by [running TPS](#how-to-run-tps)
+
+## How to run TPS
+### Installation
+TPS requires several packages to operate properly. To install TPS and
+required packages, use the create_venv.py script provided in the `testing/tps` directory:
+```sh
+python3 create_venv.py /path/to/create/virtualenv
+```
+
+This script will create a virtalenv and install TPS into it.
+
+You must then activate the virtualenv by executing:
+
+-  (mac/linux):
+```sh
+source /path/to/virtualenv/Scripts/activate
+```
+-  (win):
+```sh
+/path/to/virtualenv/Scripts/activate.bat
+```
+
+TPS can then be run by executing:
+```sh
+runtps --binary=/path/to/firefox
+```
+
+> Note: You can run the tps tests in headless mode by using `MOZ_HEADLESS=1`. This will make
+> your computer somewhat useable while the tests are running.
+
+When you are done with TPS, you can deactivate the virtualenv by executing
+`deactivate`
+
+### Configuration
+To edit the TPS configuration, do not edit config/config.json.in in the tree.
+Instead, edit config.json inside your virtualenv; it will be located at the
+top level of where you specified the virtualenv be created - eg, for the
+example above, it will be `/path/to/create/virtualenv/config.json`
+
+#### Setting Up Test Accounts
+
+##### Mozilla Accounts
+To create a test account for using the Mozilla Account authentication perform the
+following steps:
+
+> Note: Currently, the TPS tests rely on how restmail returns the verification code
+> You should use restmail or something very similar.
+> Gmail and other providers might give a `The request was blocked for security reasons`
+
+1. Go to the URL: http://restmail.net/mail/%account_prefix%@restmail.net
+  - Replace `%account_prefix%` with your own test name
+2. Go to https://accounts.firefox.com/signup?service=sync&context=fx_desktop_v1
+3. Sign in with the previous chosen email address and a password
+4. Go back to the Restmail URL, reload the page
+5. Search for the verification link and open that page
+
+Now you will be able to use this account for TPS. Note that these
+steps can be done in either a test profile or in a private browsing window - you
+might want to avoid doing that in a "real" profile that's already connected to
+Sync.
