Entry and exit criterias are certain conditions that should be satisfied in order to enter or exit a specific project or cycle. In case of software testing, entry criteria defines the conditions to be satisfied in order for the testing to begin and exit criteria define the conditions that have to be satisfied in order to stop the testing. Both of these will be defined in the test plan. Once the entry and exit criteria are defined, approval should be obtained from the stakeholders if there is change in the defined conditions.
