Traditional CMMI or waterfall development model
The traditional CMMI or waterfall development model is a linear approach to software development that involves a sequential process of planning, design, implementation, testing, and maintenance. In this model, testing is typically performed at the end of the development process, after the software system has been fully implemented.
In the testing process for traditional CMMI or waterfall development model, the testing activities typically follow these steps:
Requirements analysis: This involves reviewing the software requirements and identifying the testing requirements.
Test planning: This involves defining the objectives, scope, and resources required for the testing effort. A test plan is created that outlines the testing strategy, test scenarios, and test cases.
Test design: This involves creating test scenarios and test cases based on the test plan. The test cases may be designed for functional testing, performance testing, security testing, or other types of testing.
Test execution: This involves running the test cases and documenting the results. The test execution may be performed manually or with the help of automated testing tools.
Defect reporting: This involves documenting and reporting any defects or issues that are identified during the testing process.
Defect tracking: This involves tracking the progress of defect resolution and ensuring that all defects are addressed before the software system is released.
Test closure: This involves documenting the results of the testing process and evaluating the overall effectiveness of the testing effort. Lessons learned may be identified and used to improve future testing efforts.
The traditional CMMI or waterfall development model has some limitations when it comes to testing. Testing is typically performed at the end of the development process, which can lead to delays in identifying and addressing defects. Additionally, the linear nature of the development process can make it difficult to respond to changes in requirements or unexpected issues that arise during development. Despite these limitations, the traditional CMMI or waterfall development model is still widely used in software development today. It can be particularly useful in situations where the requirements are well-defined and stable, and where there is a need for strict control over the development process.
