Which one of the following is a typical entry criteria for testing?

A typical entry criterion for testing is the availability of testable requirements. Testable requirements

provide a basis for designing and executing test cases. Without clear and testable requirements, it is

challenging to determine what needs to be tested and to create effective test cases. Entry criteria

ensure that the necessary preconditions are met before testing begins, which helps in conducting

efficient and effective testing.
