Traditionally, testing is done first at end of the design phase, however this is no longer the case. Testing, finding, and categorising bugs, as well as releasing the development changes into the product, carries a price tag. If the test/verification team discovers a high-severity issue at the end of the lifecycle, the costs may climb. Even if all of the issues are resolved, the release could be delayed. Shift-Left testing is done in isolation by the test/verification team and does not increase testing time, but it has demonstrated to be in sync with product development in some cases. In the context of a process, shifting-left refers to taking action early on. Shift-left testing refers to the practise of testing software earlier in the development cycle than is customary, or to the left in the delivery pipeline, as opposed to the traditional practise of testing software later in the development cycle. Shifting to a "shift left" strategy assumes that the software development team may find bugs faster if they test their code as it is being written, rather than waiting until the end of the project based on fuzzy. Before the code is available for testing, shift left testing encourages developers to write test cases. An agile software development strategy known as "shift left" stresses putting test cases in place early in the life cycle of a project rather than at the conclusion. It also means that automated tests will cover a larger portion of a project's planned functionality rather to just a small portion. The shift left testing adoption benefits the organization to reduce the development cost and time as the testing is done along with development to avoid delay in the process. This paper analyse the benefits of organizations who adopted shift left testing in the software development process. |
