+# WPT Test Certificates
+
+The web-platform-tests project maintains a set of SSL certificates to allow
+contributors to execute tests requiring HTTPS locally.
+
+## Trusting Root CA
+
+To prevent browser SSL warnings when running HTTPS tests locally, the
+web-platform-tests Root CA file `cacert.pem` in the `tools/certs/` directory
+must be added as a trusted certificate in your OS/browser.
+
+For Firefox, go to about:preferences and search for "certificates".
+
+For browsers that use the Certificate Authorities of the underlying OS, such as
+Chrome and Safari, you need to adjust the OS. For macOS, go to Keychain Access
+and add the certificate under **login**.
+
+**NOTE**: The CA should not be installed in any browser profile used
+outside of tests, since it may be used to generate fake
+certificates. For browsers that use the OS certificate store, tests
+should therefore not be run manually outside a dedicated OS instance
+(e.g. a VM). To avoid this problem when running tests in Chrome or
+Firefox, use `wpt run`, which disables certificate checks and therefore
+doesn't require the root CA to be trusted.
+
+## Regenerating certificates
+
+If you wish to generate new certificates for any reason, it's possible to use
+OpenSSL when starting the server, or starting a test run, by providing the
+`--ssl-type=openssl` argument to the `wpt serve` or `wpt run` commands.
+
+If you installed OpenSSL in such a way that running `openssl` at a
+command line doesn't work, you also need to adjust the path to the
+OpenSSL binary. This can be done by adding a section to `config.json`
+like:
+
+```
+"ssl": {"openssl": {"binary": "/path/to/openssl"}}
+```
+
+On Windows using OpenSSL typically requires installing an OpenSSL distribution.
+[Shining Light](https://slproweb.com/products/Win32OpenSSL.html)
+provide a convenient installer that is known to work, but requires a
+little extra setup, i.e.:
+
+Run the installer for Win32_OpenSSL_v1.1.0b (30MB). During installation,
+change the default location for where to Copy OpenSSL Dlls from the
+System directory to the /bin directory.
+
+After installation, ensure that the path to OpenSSL (typically,
+this will be `C:\OpenSSL-Win32\bin`) is in your `%Path%`
+[Environment Variable](http://www.computerhope.com/issues/ch000549.htm).
+If you forget to do this part, you will most likely see a 'File Not Found'
+error when you start wptserve.
+
+Finally, set the path value in the server configuration file to the
+default OpenSSL configuration file location. To do this, create a file
+called `config.json`.  Then add the OpenSSL configuration below,
+ensuring that the key `ssl/openssl/base_conf_path` has a value that is
+the path to the OpenSSL config file (typically this will be
+`C:\\OpenSSL-Win32\\bin\\openssl.cfg`):
+
+```
+{
+  "ssl": {
+    "type": "openssl",
+    "encrypt_after_connect": false,
+    "openssl": {
+      "openssl_binary": "openssl",
+      "base_path: "_certs",
+      "force_regenerate": false,
+      "base_conf_path": "C:\\OpenSSL-Win32\\bin\\openssl.cfg"
+    },
+  },
+}
+```
+
+### Regenerating the pregenerated certificates
+
+From the root, run `./wpt serve --config tools/certs/config.json` and terminate
+it after it has started up.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+        # In the case where we don't have a full set of runs, the expected behaviour

+        # and more best-effort

+        #   have. In cases where it does match, record the new results
+        # * Where all the new results match, update the right hand side of that

+"""Runner for web-platform-tests
+
+The runner has several design goals:
+
+* Tests should run with no modification from upstream.
+
+* Tests should be regarded as "untrusted" so that errors, timeouts and even
+  crashes in the tests can be handled without failing the entire test run.
+
+* For performance tests can be run in multiple browsers in parallel.
+
+The upstream repository has the facility for creating a test manifest in JSON
+format. This manifest is used directly to determine which tests exist. Local
+metadata files are used to store the expected test results.

+    Records for each developer resource load that the DevTools front-end issues
+    (e.g. to load a source map) several enum values encoding which load method
+    was used, whether a fallback was used (and why), and whether the method
+    succeeded or not.
+
+    Some explanations to make sense of the enum values:
+
+    LoadsThroughPage = LoadThroughPageViaTarget + LoadThroughPageViaFrame
+    SuccessfulLoadsThroughPage = LoadsThroughPage - LoadThroughPageFailure
+
+    LoadThroughPageFallback is the number of loads that can in principle be
+    loaded through the page, but had to use the fallback because either loading
+    through the page failed (LoadThroughPageFailure), or there was insufficient
+    information to dispatch the load through the page; the number of such loads
+    can be computed as LoadThroughPageFallback - LoadThroughPageFailure.
+
+    The number of loads not eligible for loading through the page can be
+    computed as FallbackPerOverride + FallbackPerProtocol, where
+    FallbackPerOverride indicates loads where the DevTools user disabled loading
+    through the page via an override, and FallbackPerProtocol indicates loads
+    where DevTools could not load the resource via the page due to the
+    resource's protocol scheme.
+
+    The total number of loads that used the fallback can be computed as
+    LoadThroughPageFallback + FallbackPerOverride + FallbackPerProtocol. Adding
+    SuccessfulLoadsThroughPage to that number gives the total number of loads.
