Use events from Selenium to trigger autoscaling with Kedify and KEDA

Selenium is an open-source framework for automated web testing. It supports multiple browsers and platforms, allowing tests to be run in parallel across a distributed network of nodes.

It’s ideal for automated testing across various platforms and browsers. Integrated with KEDA, Selenium Grid can scale up or down dynamically based on the demand for testing resources, ensuring efficient and responsive testing environments.

Featured Use Cases

Scenario:

A software development team needs to ensure timely execution of automated tests in their CI/CD pipeline.

Selenium Scaler Usage:

Scale based on the number of queued test requests in Selenium Grid, ensuring browser nodes are available as demand varies.

KEDA Usage:

KEDA automatically scales the number of browser nodes based on the queued test requests, reducing wait times and improving feedback loops in the development cycle.

Scenario:

Web developers need to ensure their application works seamlessly across different browsers and versions.

Selenium Scaler Usage:

Scale jobs to test application compatibility across multiple browser configurations, triggered by development cycles.

KEDA Usage:

Utilizing KEDA, the system scales up browser nodes when compatibility tests are initiated, ensuring comprehensive coverage without manual resource management.

Scenario:

Testing interactive web applications such as games or financial trading platforms that require real-time user interaction.

Selenium Scaler Usage:

Scale testing nodes based on the queue of interactive test sessions, ensuring responsiveness and performance under user simulation.

KEDA Usage:

KEDA dynamically initiates browser nodes as interactive test sessions are queued, ensuring efficient resource allocation and test execution.
