+# Running Tests with real USB connected devices for the new about:debugging
+
+This document explains how to test with real USB connected devices.
+
+## Tests overview
+
+The tests that use a real device are located in `devtools/client/aboutdebugging/test/browser/`and the name of tests starts with `browser_aboutdebugging_real`. These are normal mochitest, but we need to setup the environment before starting tests.
+
+## Setup environment
+### Real device side
+1. Enable USB debugging on your device
+2. Launch Firefox
+3. Enable USB debugging on your Firefox
+4. Connect to your PC via USB
+
+You can refer to https://firefox-source-docs.mozilla.org/devtools-user/about_colon_debugging/index.html#connecting-to-a-remote-device
+
+### PC side
+Setup the real device information to evaluate the validity in tests.
+
+1. Copy a sample file which is located at `devtools/client/aboutdebugging/test/browser/real/usb-runtimes-sample.json` and rename it for example to `devtools/client/aboutdebugging/test/browser/real/local-usb-runtimes.json`.
+2. Edit the file.
+
+   This is a JSON file like below, write your real device information in here. This example indicates that there should be one USB device and should be displayed `Pixel 2` as device name and `Firefox Nightly` as short name on the sidebar of about:debugging. Regarding the other information, please see `Detail of config file` section of this document.
+
+```
+[
+  {
+    "sidebarInfo": {
+      "deviceName": "Pixel 2",
+      "shortName": "Firefox Nightly"
+    },
+    ...
+  },
+  ...
+]
+```
+
+## Test
+Normally, although we do test `./mach mochitest <path>`, to load the real device information created, specify the path as `USB_RUNTIME` environment variable, then do test.
+For example, if the name of the saved file is `devtools/client/aboutdebugging/test/browser/real/local-usb-runtimes.json`, run all real device test with a command like the one below:
+
+```
+USB_RUNTIMES=devtools/client/aboutdebugging/test/browser/real/local-usb-runtimes.json ./mach mochitest devtools/client/aboutdebugging/test/browser/browser_aboutdebugging_real
+```
+
+If there is no `USB_RUNTIMES` environment variable, the tests will not run. This is also to avoid to run on try-server and so on.
+
+## Detail of config file
+
+```
+[
+  {
+    "sidebarInfo": {
+      "deviceName": "Pixel 2", // This should display as device name on the sidebar.
+      "shortName": "Firefox Nightly" // This should display as short name on the sidebar.
+    },
+    "runtimeDetails": {
+      "info": {
+        "name": "Mozilla Nightly", // This should display on the runtime info of runtime page.
+        "version": "64.0a1" // This should display on the runtime info of runtime page.
+      }
+    }
+  }
+  // Of course, you can append additional USB devices. Some tests can do with multiple devices.
