+# End-To-End (e2e) Test for APM UI
+
+## Ingest static data into Elasticsearch via APM Server
+
+1. Start Elasticsearch and APM Server, using [apm-integration-testing](https://github.com/elastic/apm-integration-testing):
+
+```shell
+$ git clone https://github.com/elastic/apm-integration-testing.git
+$ cd apm-integration-testing
+./scripts/compose.py start master --no-kibana --no-xpack-secure
+```
+
+2. Download [static data file](https://storage.googleapis.com/apm-ui-e2e-static-data/events.json)
+
+```shell
+$ cd x-pack/legacy/plugins/apm/e2e/cypress/ingest-data
+$ curl https://storage.googleapis.com/apm-ui-e2e-static-data/events.json --output events.json
+```
+
+3. Post to APM Server
+
+```shell
+$ cd x-pack/legacy/plugins/apm/e2e/cypress/ingest-data
+$ node replay.js --server-url http://localhost:8200 --secret-token abcd --events ./events.json
+```
+>This process will take a few minutes to ingest all data
+
+4. Start Kibana
+
+```shell
+$ yarn kbn bootstrap
+$ yarn start --no-base-path --csp.strict=false
+```
+
+> Content Security Policy (CSP) Settings: Your Kibana instance must have the `csp.strict: false`.
+
+## How to run the tests
+
+_Note: Run the following commands from `kibana/x-pack/legacy/plugins/apm/e2e/cypress`._
+
+### Interactive mode
+
+```
+yarn cypress open
+```
+
+### Headless mode
+
+```
+yarn cypress run
+```
+
+## Reproducing CI builds
+
+>This process is very slow compared to the local development described above. Consider that the CI must install and configure the build tools and create a Docker image for the project to run tests in a consistent manner.
+
+The Jenkins CI uses a shell script to prepare Kibana:
+
+```shell
+# Prepare and run Kibana locally
+$ x-pack/legacy/plugins/apm/e2e/ci/prepare-kibana.sh
+# Build Docker image for Kibana
+$ docker build --tag cypress --build-arg NODE_VERSION=$(cat .node-version) x-pack/legacy/plugins/apm/e2e/ci 
+# Run Docker image
+$ docker run --rm -t --user "$(id -u):$(id -g)" \
+    -v `pwd`:/app --network="host" \
+    --name cypress cypress
+```
