The statement "Test suite coverage can be increased without the need for refactoring" is accurate because test suite coverage refers to the extent to which the test cases cover the software under test. This coverage can be enhanced by adding new tests that address areas not previously covered, without necessarily modifying the existing test structures or setups. Refactoring is often related to improving the internal design of the tests for better maintainability or performance but does not inherently affect the coverage directly .

Reliability testing is the process of checking whether the software consistently performs according to its specifications. For a commercial system with a critical internet-based user interface, ensuring that the application can handle connection failures without abnormal terminations is essential. Reliability testing would include testing the system's ability to recover from failures and continue operating, which directly addresses the risk identified.

Once existing test cases have been identified for refactoring, the next step is typically to make changes to the internal structure of these tests to improve their maintainability. This involves revising the code or scripts to make them cleaner, more efficient, and easier to understand, which helps in maintaining them over time as the software evolves. This process may also involve updating test data or dependencies to ensure that the tests remain robust and reliable .
