Fast and efficient continuous integration test system for large scale services

A proxy layer management system for testing a component in a software system, the system comprising:

• one or more processing devices and one or more storage devices storing instructions that, when executed by the one or more processing devices, causes the one or more processing device to:
• establish a target test environment which includes multiple components that interact with each other via proxy layers;
• add a test component having functionality that corresponds to a specific target component in the target test environment;
• configure the proxy layers associated with the specific target component to route traffic intended for the specific target component to the test component, and receive traffic from the test component;
• execute one or more tests in the target test environment on the test component;
• and
• route traffic, via the proxy layers, between the test component and one or more components of the target test environment instead of the specific target component.
