+# WebKitGTK MiniBrowser
+
+
+To be able to run tests with the WebKitGTK MiniBrowser you need the
+following packages installed:
+
+* Fedora: `webkit2gtk3-devel`
+* Debian or Ubuntu: `webkit2gtk-driver`
+
+
+The WebKitGTK MiniBrowser is not installed on the default binary path.
+The `wpt` script will try to automatically locate it, but if you need
+to run it manually you can find it on any of this paths:
+
+* Fedora: `/usr/libexec/webkit2gtk-4.0/MiniBrowser`
+* Debian or Ubuntu: `/usr/lib/x86_64-linux-gnu/webkit2gtk-4.0/MiniBrowser`
+  * Note: if the machine architecture is not `x86_64`, then it will be located
+    inside:
+    `/usr/lib/${TRIPLET}/webkit2gtk-4.0/MiniBrowser`
+    where `TRIPLET=$(gcc -dumpmachine)`
+
+
+Known issues:
+
+* On a docker container WebKitWebDriver fails to listen on localhost,
+because the docker container doesn't provide an IPv6 localhost address.
+To workaround this issue, manually tell it to only listen on IPv4 localhost
+by passing this parameter to wpt run: `--webdriver-arg=--host=127.0.0.1`
+Example:
+```bash
+./wpt run --webdriver-arg=--host=127.0.0.1 webkitgtk_minibrowser TESTS
+```
