Dynamic redirection of network traffic within a system under test
Redirecting network traffic within a system under test (SUT) can include receiving, within a proxy included within the SUT, a request sent from an upstream component that is directed to a downstream component, wherein the upstream component is configured to direct communications through the proxy. Within the proxy, the request can be redirected from the downstream component to a simulation component according to a routing rule within the proxy using a processor. A response can be received, within the proxy, from the simulation component and sent to the upstream component.
1. A system comprising:
a processor configured to initiate executable operations comprising:
receiving, within a proxy included within a system under test, a request sent from an upstream component that is directed to a downstream component, wherein the upstream component is configured to direct communications through the proxy;
within the proxy, redirecting the request from the downstream component to a simulation component according to a routing rule within the proxy;
receiving, within the proxy, a response from the simulation component; and
sending the response to the upstream component, wherein
the redirecting the request from the upstream component to the simulation component comprises:
determining that the request matches the routing rule, wherein the routing rule specifies the simulation component as a destination; and
sending the request to the simulation component, wherein determining that the request matches the routing rule comprises:
comparing originating information of the request with the routing rule.
2. The system of claim 1 , wherein determining that the request matches the routing rule comprises:
comparing destination information of the request with the routing rule.
3. The system of claim 1 , wherein determining that the request matches the routing rule comprises:
comparing a time stamp of the request with a time range specified by the routing rule.
4. The system of claim 1 , wherein determining that the request matches the routing rule comprises:
comparing at least a portion of a header of the request with the routing rule.
5. The system of claim 1 , wherein the processor is further configured to initiate an executable operation comprising:
publishing the routing rule within the system under test for implementation within the proxy.
6. The system of claim 5 , wherein the routing rule is published by the simulation component.
7. The system of claim 5 , wherein the processor is further configured to initiate an executable operation comprising:
responsive to the simulation component stopping operation, purging the routing rule from the proxy.
8. A computer program product, comprising:
a computer readable storage medium having computer readable program code embodied therewith that, when executed, configures a processor to perform executable operations comprising:
receiving, within a proxy included within a system under test, a request sent from an upstream component that is directed to a downstream component, wherein the upstream component is configured to direct communications through the proxy;
within the proxy, redirecting the request from the downstream component to a simulation component according to a routing rule within the proxy;
receiving, within the proxy, a response from the simulation component; and
sending the response to the upstream component, wherein
the redirecting the request from the upstream component to a simulation component comprises:
determining that the request matches the routing rule, wherein the routing rule specifies the simulation component as a destination; and
sending the request to the simulation component, wherein determining that the request matches the routing rule comprises:
comparing originating information of the request with the routing rule.
9. The computer program product of claim 8 , wherein determining that the request matches the routing rule comprises:
comparing destination information of the request with the routing rule.
10. The computer program product of claim 8 , wherein determining that the request matches the routing rule comprises:
comparing a time stamp of the request with a time range specified by the routing rule.
11. The computer program product of claim 8 , wherein determining that the request matches the routing rule comprises:
comparing at least a portion of a header of the request with the routing rule.
12. The computer program product of claim 8 , wherein the computer readable storage medium has further computer readable program code embodied therewith that, when executed, configures the processor to perform an executable operation comprising:
publishing the routing rule within the system under test for implementation within the proxy.
13. The computer program product of claim 12 , wherein the routing rule is published by the simulation component.
14. The computer program product of claim 12 , wherein the computer readable storage medium has further computer readable program code embodied therewith that, when executed, configures the processor to perform an executable operation comprising:
responsive to the test session conducted with the system under test ending, automatically purging the rule from the proxy.
