Abstract: Systems and methods for shift-left testing are disclosed. In one embodiment, a method may include an automation pipeline: receiving code for shift-left testing; testing the code with unit tests; testing a plurality of components of the code with component tests; testing the code with contract tests; testing the code with integration tests; deploying the code to an end-to-end testing environment and testing the code with end-to-end automation tests; scanning the code for security vulnerabilities; deploying the code to an end-to-end testing environment and performing production validation testing on the code; and deploying the code to a production environment.
