Answer / anil kumar
Type of matrix depends upon the particulat project.In our
project(It's a Life Sciences Web based product)following
quality matrix we use:
(i) Defect Density: Number of defects found per kilo lines
of code(KLOC)
(ii)MTTR(Mean Time To Repair): Average time required to
repair a defect after it sis detected.
(iii)Defect Removal Efficiency(DRE): E/(E+D)
Where, E= Number of errors found before delivery of the
s/w to the end user
D= Number of defects found after delivery
Ideal value of DRE is 1 i.e. No defects are found in the
software but in reality D>0

basically metrics is nothing but an mathematical number
shows a relation ship between two numbres.in testing there
are two types of metircs.
1.process metrics
2.product metrics
process metric: a metric used to measure the cheracteristic
of the methods,technique, and tools employed in
developing,imlementing,and maintaining the software system.
product metric:metric used to measure the characteristic of
the documentation and code.
some of the test metrics are:
1.user paticipation
2.path tested=number os paths tested/total number of paths
3.test cost= test cost Vs total system cost
4.cost to locate defect=test cost/No: of defects located i
n the testing
5.test automation=cost of manul test effort/total test cost
thnx,
still any doubts mail me ok indu.

Answer / santosh kunta
Hi Uday,
Here what meant by metrics, You collect various data
related to your project you baseline your project status in
various activites.... like testcases execution, number of
tc's passed in a given cycle and so on...
Some of the metrics that you can collect is
Schedule variation : difference b/w planned and actual
completion of project
Effort Variation
Productivity
Testcases Passes in a project

Answer / vileen
Testing metrics is prepared to track the following
information for a perticular month/project/release, which
varies between project and company.
1.Pre-release defect density
2.Post release defect density
3.Individual defect detection
4.Test review
5.Defect removal efficiency
6.Test case effectiveness
7.Test specification productivity(includes scripting and
executing)
8.Schedule and effort variance
9.Test progress tracking
Metrics helps to track the above information in
figures/percentage.

Answer / prasoona
Hi Uday,
we prepare the metrics in the testing based on
the project requirement.Generally we prepare following
metrics in my project on monthly basis.
Test Case Design Efficiency
Defect Finding Rate
Defect Cycle Time
Test Coverage
Test Case Efficiency
Bad Fix Ratio
No of Defects resulted in scope change
Defect detection efficiency
TDCE (Total Defect Containment Effectiveness)
Let me know if u require any clarification

Answer / kathiravan
we are using traceability metric,
Usage--Mapping the requirement with test cases to check all
the requirement are satisfied.
| Is This Answer Correct ? | 6 Yes | 8 No |
Answer / swapnil ingole
hi i m swapnil uday,
Its a mapping document that maps defects with test cases
and test cases with functional specifications and
functional specifications with business requirements.In
order trace back the defects.....
is any doubts plz mail me
