Action
1. Review Spec. &
highlight the
problem from
test of view.
2. Plan the test
schedule, test
resource &
finish the
System Test
Plan
3. Base on STP to
create Test
Design Spec.
4. Base on TDS to
create Test
Case Spec.
5. Generate Test Case
Excel file.
6. Submit Project
PTS database.

sharing
database.
8. Test Case Training.
1. Run Test Case &
fill in the
result.
2. Bug review.
3. Generate Auto Test
Script.
1. Analysis the
“Random”/
“Once” issue;
try to find out
rules.
2. Identify the root
cause of issues.
3. Clarify discussion
issues.
4. Modify the test
case.
1.Go through all the
items in final
test case
database.
2. Field Trial
1. Field Test
2. Analysis End-User
Report issue.
3. Verify the Delta
version after
MP.
4. Execute the Auto
Test Script to
cover the lack
of resource.
1. Review the Not
Suitable Test
Case.
2. Review the Not
Available Test
Case.
3. Check the coverage
of Test Plan
which is based
on Customer/
Field/ End-
User Report.
4. Modify the
standard Test
Plan.
5. Plan the test
training.
