Like other tasks, testing has to follow a priority list to ensure everything happens in a set hierarchy. It has to start with finding the objective of the test process and end with the execution summary or report. Moreover, every task in between also has to follow a priority list so that the results are as expected. If we have to list the testing tasks based on the priorities, the list should go as follows: Prepare a test plan based on the project scope and objectives. Refer to the requirement sheet that client shared and consider the resource availability to plan the strategy to ensure a successful test process. Make sure you cover all the major and minor functionalities with the data you need for the testing process. Assigning roles and responsibilities to the test team members, considering their abilities and the tasks to be completed. It is a crucial aspect of planning the process as it determines success. The next priority is to execute the test based on the plans you created in the first step and ensure everything happens in a similar way. It is essential to follow the standards set by the project manager to move toward success. When the project is in the execution phase, you should also focus on defect reporting and keep track of the progress. If required, create reports for your reference or for someone working with you on the test process. Once all the tests are complete, you can proceed to create the test summary reports and submit them to the concerned teams. It is the priority list, top to bottom, which a test engineer should follow to ensure everything happens as desired and you get the required results. You can add a few steps based on the project you are working on and fit them into your priority list, but the basic idea remains the same.
