Test Coverage Matrix

What is Test Coverage Matrix? What is Traceability matrix? whats is the difference between the two?

The test coverage is documented as simple matrix called as test coverage matrix. In this test coverage matrix the test implementation and operations are mentioned in column and the test cases are mentioned in row. It is a very good technique for test coverage. Traceability matrix is used in a software development process and is sued with high level requirements which correlate two base lined documents.

The answer was very useful but could you give a example of test coverage matrix. Also it would be nice if you could throw highlight on at what stages of software development life cycle the test coverage matrix and traceability matrix gets applied

hi,

traceability matix serves in mapping the test cases to the requirements. It serves as a checklist wherein all the requirements (of srs) are listed and the test cases covering the corresponding requirement is listed against each requirement. Every company may have their own template for rtm, but they serve the same purpose as described above.

Test coverage matrix, on the hand, is also a checklist which ensures that the functionality of the given screen(unit) is checked in all possible combinations (positive and negative) which have not been covered in test cases. Test coverage matrix is usually prepared for a screen having large number of controls(textboxes, dropdowns, buttons etc) usually, test coverage matrix is prepared in a spread sheet having all the controls (textboxes, dropdowns, buttons etc) in the columns and then all possible entries in those fields in the rows with an ''yes'' or ''no'' in the rows against the controls listed in the columns. For example, consider a ''login'' screen wherein we have ''username'' and ''password" textfields.

While preparing test coverage matrix, the first column will be ''s.no'' and the second will be ''username" and ''password" will be the third field followed by ''ok'' and ''cancel'' button. Then, in the first row for s.no 1, enter ''yes'' for both ''user name'' and ''password'' columns, ''yes'' implying that a value is entered in that field. In the second row, enter ''yes'' and ''no'' and in the third row, ''no'' and 'yes'' and so on.

The complexity increases with the number of controls in the screen. Each of the row is considered as one condition and executed while testing. This is how we prepare test coverage matrix. (this is a black box testing technique). Hope i have made sense. Cheers

[QUOTE=nehalshah;2279]Really a very interesting and useful discussion going on. I learnt a lot from this discussion.[/QUOTE]

the explination for traceabality matrics is correct. but it also includes all software development actvities include coding, design, etc but when come to test coverage matrics it only depends on how the testing is done on perticular madule in all the aspect, means different types of testing like functinal , system( performance, compatabality etc)

Hello all the discussion is really interesting. But it would be great if we could add all the types of matrix involved in Testing process so that we all could get knowledge shared about all the matrix. Could anyone initiate this. Since I am not aware of the matrix I am not initiating. Someone could take the lead.

What is exactly Horizontal traceability matrix, vertical traceability matrix and bidirectional traceability matrix?

hi

Bidirectional is backward and forward tracebility.


Forward tracebility starts from requirements, then the design and code


Backward tracebility means the opposite or rather you can say reverse direction.We see that end product has met requirements or not!

:D

Hi Nalini,

Geekinterview discussed about this Topic already.Here is the link you can refer to [url]http://www.geekinterview.com/talk/375-test-coverage-matrix.html[/url]

what are the field available in traceability matrix can any body explain with details

how we will do traceability matrix ? who will do the traceability matrix

Thanks,

tracability matrix is nothing but mapping between system requirements and test cases. it is used to check whether all the functionalities are covered or not.

It is written by testers.

s.no,tcd no,bdd no,fpd, something like this but its not complete..

A method used to validate the compliance of a process or product with the requirements for that process or product. The requirements are each listed in a row of the matrix and the columns of the matrix are used to identify how and where each requirement has been addressed.

Explain each in detail.

Metrics are measurements. Measurements are inevitable in order to have project estimates(such as cost, time, man hours..)
Basically there are two types of metrics from what i know.
1. Process related metrics
2. Product related metrics

What is Metrix and types of metrix

The purpose of traceability matrix is to ensure that mapping in between requirements of the customer and test cases designed by testengineers.

It is prepared by QA/TTL.

By using this matrics we can find out
1. whether all testcases are completed w.r.t requirements
2. How many test cases are passed How many testcases are failed
3. How many defects are fixed and how mnay are yet to be fixed when any of the testcases are failed

So that this matrix consists of coloumns from BRD to until defects are resolved that means BRD, FRS, Testcase ID, Test cases description, test cases P/F, defect ID, defect description, Defect closed/fixed/resolved.

Thanks to all the memebers.

Can any one kindly put a table format of that matrix. so that we can understand it in a better way.

Thanks in advance.

hi,
my self raghavendra i am having a dought regarding how to handle change in image by using qtp

I need to ask about Coverage Matrix on details please; as i need example "How to do the coverage" maybe by using excel sheet ???? anyone can help by giving me an example on some templete plz??? as soon as possible

Lara:

As i know these things as i can imagine how? but i need to know does it go (acoverage matrix) for all functions at the system?? or it covers format of some softwares?
do you have an example?
can you?
thank u

what is test coverage matrix? what is traceability matrix? whats is the difference between the two?

Test coverage matrix and traceability matrix represents the same. In the Test Coverge matrix we will identify that all the funtionalities represented in the requirement documents are covered and converted into the test cases. In the traceability matrix we will compare the test cases generated against the requirements, in order to validate that all the scenarios and functionalities mentioned in the requirement documents are converted into test cases. The template for the traceability matrix will be having the "Requirement ID, Name of the Test cases generated, severity of the test case (complex, simple or medium), the Build or version number, and the associated defects after the execution of the test cases"
