There are generally four recognized phases of the software testing life cycle: planning and control analysis and design implementation and execution and closure. Each stage is important in its own right but the key to a successful testing program is to ensure that adequate time and resources are allocated to each stage. In the first stage planning and control are crucial to setting the tone for the entire project. It's important to establish realistic goals and objectives for the testing effort as well as clear lines of responsibility and communication. This phase also includes identifying any risks that could impact the project such as changes in technology or personnel. The second stage of analysis and design is where the real work of testing begins. In this phase, testers analyze the requirements for the project and design test cases that will exercise all aspects of the system. It's important to remember that not all tests need to be automated; sometimes manual testing can be more effective.

The third stage is implementation and execution

The software testing life cycle is the process that software testing follows to ensure that newly developed software meets all requirements and does not contain any bugs.

The cycle begins with the planning stage in which testers determine what needs to be tested and how it will be done. This is followed by the development stage in which tests are created and run. After the tests have been run results are analyzed to determine whether the software meets all requirements. Finally, the cycle ends with reporting in which testers report their findings to stakeholders.

The software testing life cycle is the process followed to test an application or system. It involves the following steps:

1. Planning and Requirements: In this phase, the objectives of the testing process are defined and a test plan is created.

2 Design: In this phase test cases are designed based on the requirements and objectives defined in the previous stage.

3 Execution: In this stage, the actual testing is carried out according to the plan and test cases designed in the previous stage.

4 Reporting and Documentation: In this final stage results of the testing process are documented and reported.
