  1. Ensure that testing of changes is undertaken in accordance with the testing plan. Ensure that the testing is designed and conducted by a test group independent from the development team. Consider the extent to which business process owners and end users are involved in the test group. Ensure that testing is conducted only within the test environment.
  2. Ensure that the tests and anticipated outcomes are in accordance with the defined success criteria set out in the testing plan.
  3. Consider using clearly defined test instructions (scripts) to implement the tests. Ensure that the independent test group assesses and approves each test script to confirm that it adequately addresses test success criteria set out in the test plan. Consider using scripts to verify the extent to which the system meets security requirements. Consider the appropriate balance between automated scripted tests and interactive user testing.
  4. Undertake tests of security in accordance with the test plan. Measure the extent of security weaknesses or loopholes. Consider the effect of security incidents since construction of the test plan. Consider the effect on access and boundary controls.
  5. Undertake tests of system and application performance in accordance with the test plan. Consider a range of performance metrics (e.g., end-user response times and database management system update performance).
  6. When undertaking testing, ensure that the fallback and rollback elements of the test plan have been addressed.
  7. Identify, log and classify (e.g., minor, significant and mission-critical) errors during testing. Ensure that an audit trail of test results is available. Communicate results of testing to stakeholders in accordance with the test plan to facilitate bug fixing and further quality enhancement.
