+# Jest Tests for devtools/client/accessibility
+
+## About
+
+DevTools React components can be tested using [jest](https://jestjs.io/). Jest allows to test our UI components in isolation and complement our end to end mochitests.
+
+## Run locally
+
+We use yarn for dependency management. To run the tests locally:
+```
+  cd devtools/client/accessibility/test/node
+  yarn && yarn test
+```
+
+## Run on try
+
+The tests run on try on linux64 platforms. The complete name of try job is `devtools-tests`. In treeherder, they will show up as `node(devtools)`.
+
+Adding the tests to a try push depends on the try selector you are using.
+- try fuzzy: look for the job named `source-test-node-devtools-tests`
+
+The configuration file for try can be found at `taskcluster/ci/source-test/node.yml`
