+# govim integration tests
+
+Files in this directory configure Cloud Build to run [govim] integration tests
+against a gopls binary built from source.
+
+## Running on GCP
+
+To run these integration tests in Cloud Build, use the following steps. Here
+we assume that `$PROJECT_ID` is a valid GCP project and `$BUCKET` is a cloud
+storage bucket owned by that project.
+
+- `cd` to the root directory of the tools project.
+- (at least once per GCP project) Build the test harness:
+```
+$ gcloud builds submit \
+ --project="${PROJECT_ID}" \
+ --config=gopls/integration/govim/cloudbuild.harness.yaml
+```
+- Run the integration tests:
+```
+$ gcloud builds submit \
+ --project="${PROJECT_ID}" \
+ --config=gopls/integration/govim/cloudbuild.yaml \
+ --substitutions=_RESULT_BUCKET="${BUCKET}"
+```
+
+## Fetching Artifacts
+
+Assuming the artifacts bucket is world readable, you can fetch integration from
+GCS. They are located at:
+
+- logs: `https://storage.googleapis.com/${BUCKET}/log-${EVALUATION_ID}.txt`
+- artifact tarball: `https://storage.googleapis.com/${BUCKET}/govim/${EVALUATION_ID}/artifacts.tar.gz`
+
+The `artifacts.go` command can be used to fetch both artifacts using an
+evaluation id.
+
+## Running locally
+
+Run `gopls/integration/govim/run_local.sh`. This may take a while the first
+time it is run, as it will require building the test harness. This script
+accepts two flags to modify its behavior:
+
+**--sudo**: run docker with `sudo`
+**--short**: run `go test -short`
