PROCESS ASSESSMENT PREPARATION
1 Do standards and guidelines exist that
clearly define the process?
2 Has the project submitted any request for
deviations or waivers to current standards or
guidelines?
4 Have entrance and exit criteria been
established for the process assessment?
5 Are processes documented and under
configuration control?
6 Was documentation required for the
implementation of this process made
available to the participants with ample time
to review and prepare?
7 Is there evidence that all
stakeholders/participants were involved in
the implementation of the process?
8 Have all parties involved in the
implementation of the assessed process
received training on the process?
9 Were there any constraints/limitations
associated with the implementation of the
process identified?
UNIT TEST CRITERIA\COMPLIANCE
10 Were the objectives of the unit test
established:
10a The strategies to be employed
10b The coverage requirements,
10c Reporting and analysis,
10d Close-out of anomalies?

11 Has the unit test been designed to be a
test that executes all of the code in the
unit?
Tip: Is there evidence that the unit
test executed every statement in the
unit, including all branches of
conditional statements?
12 Does the unit test satisfy the
requirement for full path coverage and
boundary value testing?
13 Is there sufficient documentation on
the unit test to make it clear what is
being tested and the general test
approach?
14 Has it been confirmed that anomalies
during unit test are software
anomalies, and not problems detected
for other reasons?
15 Have comments in the source code
been paired with comments in the unit
test code to verify that all conditional
branches have been tested and paths
have been covered?
16 Was each conditional branch in the unit
executed?
17 Were all operations that might cause
erroneous execution (i.e., divide by zero,
taking square root of negative number, etc.)
proved impossible?
18 Were all parameters and inputs to
subprograms tested with nominal
values and with values at the
extremes by the algorithm, compiler,
and CPU?
19 Were changes to the module source code
required to run unit test?
20 Is there documentation regarding the test
environment the unit was tested on?
21 Is the unit test repeatable, and will identical
results be produced?
22 Can the unit test be run automatically
without user interaction?

23 Have the data files used by the unit
test been treated as source code for the
purpose of Configuration
Management?
24 Do distinct elements of input vectors
and matrices have distinct values for
the purpose of catching indexing
errors?
25 Do inputs have distinct values?
(If input’s order to an operation matter, the
input’s should have distinct values to catch
order errors.)
POST ASSESSMENT ACTIVITIES
26 Are unit tests and test results stored in the
software development folders or other
artifact files?
27 At the conclusion of the assessment, is
an understanding reached between
development, test, system engineering,
QA, & CM on the validity and degree
of completeness of the Unit Test
process?
28 Did all designated parties concur in
the acceptability of the Unit Test
process (i.e., was there a legitimate
reason to deviate from the process)?
29 Have all artifacts been placed under
formal configuration control (e.g., unit
test results, unit test logs)?
30 Were Lessons Learned addressed and
captured?
