A system and method for improving integration testing in a cloud computing environment includes collecting one or more input parameters associated with each of one or more products, deployed in cloud computing environment, from one or more external resources and test management systems. The input parameters include one or more defect parameters, user requirements, test parameters or performance parameters associated with the product. The integration testing improvement system determines one or more failure issues associated with the product and analyzes the behavior of the product over a predetermined time period to identify a failure pattern associated with the product. Each of the determined failure issues is mapped with the identified failure pattern to detect one or more critical scenarios in each of the products. Later the critical scenarios are automated by executing associated test scripts thereby improving the integration testing in the cloud computing environment.
