License key

Do you need to test Fleet Premium features locally?

Use the --dev_license flag to use the default development license key.

For example:

./build/fleet serve --dev --dev_license

Simulated hosts

It can be helpful to quickly populate the UI with simulated hosts when developing or testing features that require host information.

Check out /tools/osquery directory instructions for starting up simulated hosts in your development environment.

Test suite

You must install the golangci-lint command to run make test[-go] or make lint[-go], using:

go install[email protected]

Make sure it is available in your PATH. To execute the basic unit and integration tests, run the following from the root of the repository:


Go unit tests

To run all Go unit tests, run the following:


Go linters

To run all Go linters and static analyzers, run the following:

make lint-go

Javascript unit tests

To run all JS unit tests, run the following:

make test-js


yarn test

Javascript linters

To run all JS linters and static analyzers, run the following:

make lint-js


yarn lint

MySQL tests

To run MySQL integration tests, set environment variables as follows:

MYSQL_TEST=1 make test-go

Email tests

To run email related integration tests using MailHog set environment as follows:

MAIL_TEST=1 make test-go

Network tests

A few tests require network access as they make requests to external hosts. Given that the network is unreliable and may not be available. Those hosts may also be unavailable so these tests are skipped by default. They are opt-in via the NETWORK_TEST environment variable. To run them:

NETWORK_TEST=1 make test-go

Viewing test coverage

When you run make test or make test-go from the root of the repository, a test coverage report is generated at the root of the repo in a filed named coverage.txt

To explore a test coverage report on a line-by-line basis in the browser, run the following:

go tool cover -html=coverage.txt

To view test a test coverage report in a terminal, run the following:

go tool cover -func=coverage.txt

End-to-end tests

E2E tests are run using Docker and Cypress.

E2E tests are constantly evolving, and running them or examining CI results is the best way to understand what they cover, but at a high level, they cover:

  1. Setup
  2. Log in/out flows
  3. Host page Add hosts Label flows
  4. Query flows
  5. Policy flows
  6. Schedule flows scheduling packs
  7. Permissions Admin Observer (global and team) Maintainer
  8. Organizational Settings Settings adjustments Users


Make sure dependencies are up to date and to build the Fleet binaries locally.

For Fleet Free tests:

make e2e-reset-db
make e2e-serve-free

For Fleet Premium tests:

make e2e-reset-db
make e2e-serve-premium

This will start a local Fleet server connected to the E2E database. Leave this server running for the duration of end-to-end testing.

make e2e-setup

This will initialize the E2E instance with a user.

Run tests

Tests can be run in interactive mode or from the command line.


For Fleet Free tests:

yarn e2e-browser:free

For Fleet Premium tests:

yarn e2e-browser:premium

Use the graphical UI controls to run and view tests.

Command line

For Fleet Free tests:

yarn e2e-cli:free

For Fleet Premium tests:

yarn e2e-cli:premium

Tests will run automatically, and results are reported to the shell.

Test hosts

The Fleet repo includes tools to start testing osquery hosts. Please see the documentation in /tools/osquery for more information.


Manually testing email with MailHog

To intercept sent emails while running a Fleet development environment, first, as an Admin in the Fleet UI, navigate to the Organization settings.

Then, in the "SMTP options" section, enter any email address in the "Sender address" field, set the "SMTP server" to localhost on port 1025, and set "Authentication type" to None. Note that you may use any active or inactive sender address.

Visit localhost:8025 to view MailHog's admin interface displaying all emails sent using the simulated mail server.

Development database management

In the course of development (particularly when crafting database migrations), it may be useful to backup, restore, and reset the MySQL database. This can be achieved with the following commands:


make db-backup

The database dump is stored in backup.sql.gz.


make db-restore

Note that a "restore" will replace the state of the development database with the state from the backup.


make db-reset

MySQL shell

Connect to the MySQL shell to view and interact directly with the contents of the development database.

To connect via Docker:

docker-compose exec mysql mysql -uroot -ptoor -Dfleet

Redis REPL

Connect to the redis-cli in REPL mode to view and interact directly with the contents stored in Redis.

docker-compose exec redis redis-cli

Testing SSO

Fleet's docker-compose file includes a SAML identity provider (IdP) for testing SAML-based SSO locally.


Configure SSO on the Organization Settings page with the following:

Identity Provider Name: SimpleSAML
Entity ID: https://localhost:8080
Issuer URI: http://localhost:8080/simplesaml/saml2/idp/SSOService.php
Metadata URL: http://localhost:9080/simplesaml/saml2/idp/metadata.php

The identity provider is configured with two users:

Username: sso_user
Email: [email protected]
Password: user123#

Username: sso_user2
Email: [email protected]
Password: user123#

Use the Fleet UI to invite one of these users with the associated email. Be sure the "Enable single sign-on" box is checked for that user. Now, after accepting the invitation, you should be able to log in as that user by clicking "Sign on with SimpleSAML" on the login page.

To add additional users, modify tools/saml/users.php and restart the simplesaml container.

Testing Kinesis Logging

Tip: Install AwsLocal to ease interaction with LocalStack. Alternatively, you can use the aws client and use --endpoint-url=http://localhost:4566 on all invocations.

The following guide assumes you have server dependencies running:

docker-compose up
# (Starts LocalStack with kinesis enabled.)

First, create one stream for "status" logs and one for "result" logs (see for more information around the two types of logs):

$ awslocal kinesis create-stream --stream-name "sample_status" --shard-count 1
$ awslocal kinesis create-stream --stream-name "sample_result" --shard-count 1
$ awslocal kinesis list-streams
    "StreamNames": [

Use the following configuration to run Fleet:


Here's a sample command for running fleet serve:

make fleet && FLEET_OSQUERY_RESULT_LOG_PLUGIN=kinesis FLEET_OSQUERY_STATUS_LOG_PLUGIN=kinesis FLEET_KINESIS_REGION=us-east-1 FLEET_KINESIS_ENDPOINT_URL=http://localhost:4566 FLEET_KINESIS_ACCESS_KEY_ID=default FLEET_KINESIS_SECRET_ACCESS_KEY=default FLEET_KINESIS_STATUS_STREAM=sample_status FLEET_KINESIS_RESULT_STREAM=sample_result ./build/fleet serve --dev --dev_license --logging_debug

Fleet will now be relaying "status" and "result" logs from osquery agents to the LocalStack's kinesis.

Let's work on inspecting "status" logs received by Kinesis ("status" logs are easier to verify, to generate "result" logs so you need to configure "schedule queries").

Get "status" logging stream shard ID:

$ awslocal kinesis list-shards --stream-name sample_status

    "Shards": [
            "ShardId": "shardId-000000000000",
            "HashKeyRange": {
                "StartingHashKey": "0",
                "EndingHashKey": "340282366920938463463374607431768211455"
            "SequenceNumberRange": {
                "StartingSequenceNumber": "49627262640659126499334026974892685537161954570981605378"

Get the shard-iterator for the status logging stream:

awslocal kinesis get-shard-iterator --shard-id shardId-000000000000 --shard-iterator-type TRIM_HORIZON --stream-name sample_status

    "ShardIterator": "AAAAAAAAAAERtiUrWGI0sq99TtpKnmDu6haj/80llVpP80D4A5XSUBFqWqcUvlwWPsTAiGin/pDYt0qJ683PeuSFP0gkNISIkGZVcW3cLvTYtERGh2QYVv+TrAlCs6cMpNvPuW0LwILTJDFlwWXdkcRaFMjtFUwikuOmWX7N4hIJA+1VsTx4A0kHfcDxHkjYi1WDe+8VMfYau+fB1XTEJx9AerfxdTBm"

Finally, you can use the above ShardIterator to get "status" log records:

awslocal kinesis get-records --shard-iterator AAAAAAAAAAERtiUrWGI0sq99TtpKnmDu6haj/80llVpP80D4A5XSUBFqWqcUvlwWPsTAiGin/pDYt0qJ683PeuSFP0gkNISIkGZVcW3cLvTYtERGh2QYVv+TrAlCs6cMpNvPuW0LwILTJDFlwWXdkcRaFMjtFUwikuOmWX7N4hIJA+1VsTx4A0kHfcDxHkjYi1WDe+8VMfYau+fB1XTEJx9AerfxdTBm

Testing pre-built installers

Pre-built installers are kept in a blob storage like AWS S3. As part of your your local development there's a MinIO instance running on http://localhost:9000. To test the pre-built installers functionality locally:

  1. Build the installers you want using fleetctl package. Be sure to include the --insecure flag for local testing.
  2. Use the installerstore tool to upload them to your MinIO instance.
  3. Configure your fleet server setting FLEET_PACKAGING_GLOBAL_ENROLL_SECRET to match your global enroll secret.
  4. Set FLEET_SERVER_SANDBOX_ENABLED=1, as the endpoint to retrieve the installer is only available in the sandbox.

Be sure to replace the FLEET_PACKAGING_GLOBAL_ENROLL_SECRET value above with the global enroll secret from the fleetctl package command used to build the installers.

MinIO also offers a web interface at http://localhost:9001. Credentials are minio / minio123!.


You can configure the server to record and report trace data using OpenTelemetry or Elastic APM and use a tracing system like Jaeger to consume this data and inspect the traces locally.

Please refer to tools/telemetry for instructions.
