 There are two test suites associated with Mapbox GL JS

+Verify correctness and consistency of [mapbox-gl-js](https://github.com/mapbox/mapbox-gl-js) and
+[mapbox-gl-native](https://github.com/mapbox/mapbox-gl-native) rendering.
+
+## Organization
+
+Tests are contained in a directory tree, generally organized by [style specification](https://github.com/mapbox/mapbox-gl-style-spec)
+property: `background-color`, `line-width`, etc., with a second level of directories below that for individual tests.
+
+Within a leaf directory is a `style.json` file, which contains the minimal style needed for the given test case. The style can specify the map size, center, bearing, and pitch, and additional test metadata. The expected output for a given test case is in `expected.png`, e.g. [`tests/background-color/constant/expected.png`](https://github.com/mapbox/mapbox-gl-js/blob/master/test/integration/render-tests/background-color/constant/expected.png).
+
+Supporting files -- glyphs, sprites, and tiles -- live in their own respective subdirectories at the top level. The test
+harness sets up the environment such that requests for these resources are directed to the correct location.
+
+The contents of vector tile fixtures can be read using the [`vt2geojson`](https://github.com/mapbox/vt2geojson) tool
+
+## Running tests
+
+Run `npm run test-suite` in mapbox-gl-js or mapbox-gl-native. To view the results graphically, run:
+
+```
+open ./test/integration/render-tests/index.html
+```
+or
+```
+open ./test/integration/query-tests/index.html
+```
+
+When run via Travis, the test artifacts are uploaded to S3 as a permanent record of results. Near the
+end of the Travis output is a link to the result, for example:
+
+http://mapbox.s3.amazonaws.com/mapbox-gl-native/tests/5952.10/index.html
+
+## Writing new tests
+
+Expected results are always generated with the **js** implementation. This is merely for consistency and does not
+imply that in the event of a rendering discrepancy, the js implementation is always correct.
+
+```

+
+### Reading Vector Tile Fixtures
+
+Install `vt2geojson`, a command line utility which turns vector tiles into geojson, and `harp`, a simple file server.
+
+```
+npm install -g vt2geojson harp
+```
+
+Start a static file server
+```
+harp server .
+```
+
+Read the contents of an entire vector tile
+
+```
+vt2geojson -z 14 -y 8803 -x 5374 http://localhost:9000/tiles/14-8803-5374.mvt
+```
+
+Read the contents of a particular layer in a vector tile
+
+```
+vt2geojson --layer poi_label -z 14 -y 8803 -x 5374 http://localhost:9000/tiles/14-8803-5374.mvt
