This statement is false because the CMMI does not have defined levels specifically for testing maturity. The CMMI model is more general and focuses on overall process improvement across various disciplines, including but not limited to testing. CMMI includes practices like verification and validation but does not specifically address a structured path to testing maturity, unlike TMMi, which defines specific levels for testing process maturity. Therefore, statement D is incorrect.
Reference:
The TMMi document clarifies that while CMMI includes testing-related process areas (such as verification and validation), it does not define testing maturity at various levels as TMMi does.
