Abstract

Methods and systems are presented for testing software applications in a production-like environment that simulates real-world failures of production environments. A production environment has production applications and databases configured to process user requests from users for conducting transactions with a service provider. A testing system provides an intermediate interface that enables a software application operating in the test environment to access at least one of a production application or a production database. The intermediate interface can be configured based on different failure configurations to simulate production component failures in the production environment. Failure injection and randomized failure modes can be employed, including for network-related failures (latency, dropped packets, connections, etc.) that might occur in the production environment.

Claims20

Dependent claims

A system, comprising:

a processor;
and
a non-transitory computer-readable medium having stored thereon instructions that are executable to cause the system to perform operations comprising:
receiving an indication of a transaction request, the indication received in a testing environment configured based on one or more failure configurations to simulate one or more failure modes applicable to a production environment;
generating a copy of the transaction request;
transmitting the transaction request to the production environment for processing, wherein a first transaction processing engine within the production environment is configured to process the transaction request by accessing one or more production database nodes that are in the production environment;
transmitting the copy of the transaction request to the testing environment for processing, wherein a second transaction processing engine within the testing environment is configured to process the copy of the transaction request by accessing the one or more production database nodes according to the one or more failure configurations;
determining a result of the second transaction processing engine attempting to process the copy of the transaction request;
and
storing the result, wherein the result includes information relating to a status of the second transaction processing engine within the testing environment.

A non-transitory computer-readable medium having stored thereon instructions that are executable by a computer system to cause the computer system to perform operations comprising:

receiving an indication of a transaction request, the indication received in a testing environment configured based on one or more failure configurations to simulate one or more failure modes applicable to a production environment;
transmitting the transaction request to the production environment for processing, wherein a first transaction processing engine within the production environment is configured to process the transaction request by accessing one or more production database nodes that are in the production environment;
transmitting a copy of the transaction request to the testing environment for processing, wherein a second transaction processing engine within the testing environment is configured to process the copy of the transaction request by accessing the one or more production database nodes according to the one or more failure configurations;
determining a result of the second transaction processing engine attempting to process the copy of the transaction request;
and
storing the result, wherein the result includes information relating to a status of the second transaction processing engine within the testing environment.

3 more elements

A method, comprising:

receiving, at a computer system, an indication of a transaction request, the indication received in a testing environment configured based on one or more failure configurations to simulate one or more failure modes applicable to a production environment;
transmitting the transaction request to the production environment for processing, wherein a first transaction processing engine within the production environment is configured to process the transaction request by accessing one or more production database nodes that are in the production environment;
transmitting a copy of the transaction request to the testing environment for processing, wherein a second transaction processing engine within the testing environment is configured to process the copy of the transaction request by accessing the one or more production database nodes according to the one or more failure configurations;
determining a result of the second transaction processing engine attempting to process the copy of the transaction request;
and
storing the result, wherein the result includes information relating to a status of the second transaction processing engine within the testing environment.
