Emulating LaunchDarkly Downtime

This topic covers strategies for emulating LaunchDarkly downtime in your tests.

Use Case

Validate that your application behaves correctly when LaunchDarkly is unavailable. The goal of these tests is to ensure:

• The application does not block indefinitely for initialization
• Fallback values are updated and well maintained

Methods

• Playwright

Relay Proxy

If SDKs connect through the Relay Proxy, read Emulating Relay Proxy issues for how to test when the proxy is down or when LaunchDarkly is unreachable upstream of the proxy.
