1. A processor implemented method to perform a set of performance tests on an application in a continuous deployment pipeline, the method comprising: identifying, with a decision engine executed by a processor, a set of code changes between a baseline build and a new build, the baseline build and the new build being two distinct builds in a performance test environment; obtaining, with a test engine executed by the processor, a baseline test result by executing a set of customized test scripts on the baseline build in the performance test environment, the baseline build including a first code base that successfully completed the set of performance tests in the continuous deployment pipeline; testing, with the test engine executed by the processor, the new build by executing the set of customized test scripts on the new build in the performance test environment to obtain a new test result, the new build including a second code base being tested in the continuous deployment pipeline; and determining, with a decision engine executed by the processor, a performance value by comparing the baseline test result and the new test result.
