Percentage of testing covered at a given time is known as Coverage status. It helps in tracking project status.

They saved automatically when the users clicks on "END RUN" in the Test Lab.

Using QTP add-in in Quality Center we can use QTP as an automation tool.

The interfaces of QC are:

Site Admin
Quality Center

Test instance is required to run the test case in the lab. We can't directly test case in the lab, instead we need to run test instance of that test case.

Quality Center is a test management tool which supports various phases of software development life cycle whereas BugZilla is Defect Management tool only.

The dashboard analysis has two components.

Analysis View which contain analysis tree.
Dashboard View which contains dashboard tree.

Quality center is the advanced version of Test Director. It has more features than Test Director.

We determine the risk category for each assessment requirement under the analysis requirement, It has two factors:

Business Criticality
Failure Probability.

When a Quality Center Project is created we have to store and manage the data generated and collected by Quality Center. Each and every project is supported by a database that is used to store project information. The following database applications are used to store and manage Quality Center information:

☛ Oracle 9.2.0.6 Standard/Enterprise Edition
☛ Oracle 10.2.0.3
☛ Microsoft SQL Server 2005 (SP2).

Quality Center live analyses graph provides a visual overview of all tests within a folder in test plan tree.

Yes, Quality center comes with two kinds of licenses:

☛ Quality Center for Windows.
☛ Quality Center for UNIX.

The users group determines the privileges that the user has within a project.

There is difference in switching between two projects in Quality Center 9.0 and above and in other versions.

QC 9.0:- Select Tools then Change Projects and Select Project.

Other versions: Log-off and log-in again.

Following types of tabs are available:
☛ 1. Requirement: Helps in tracking the customer requirements.
☛ 2. Test plan: Helps in designing the test cases and to store the test scripts.
☛ 3. Test lab: Helps in executing the test cases and track the results.
☛ 4. Defect: Helps in logging a defect and to track the logged defects.

We can map the requirements with test cases in QC:

1. In the requirements tab select coverage view.
2. Select requirement by clicking on parent/child or grandchild.
3. On right hand side another window will appear. It has two tabs:
(a) Tests coverage
(b) Details
Test coverage tab will be selected by default or you click on it.
4. Click on select tests button a new window will appear on right hand side and you will see a list of all tests. You can select any test case you want to map with your requirements.

Roles & responsibilities of QC Admin are:

☛ Project Creation
☛ Managing users and their authentication.
☛ Performance monitoring.
☛ Data backup etc.

Reports and graphs can be generated any time and in each and every phase with QC module during the testing process by using default or customize settings like requirement, test plan, test lab or defect module. We can also get summary and progress reports.

A file can be exported from any of the following tab in excel or word format.

☛ Requirement tab:
Right click on main Requirement
Click on export
Save as word, excel or other template.

☛ Test plan tab:
Select a test script.
Click on the design steps tab.
Right click anywhere in the window
Click on export and save as.Note: Only individual test can be exported. No parent child export is possible.

☛ Test lab tab:
Select a child group.
Click on execution grid.
Right click and save in excel or other format.

☛ Defects Tab:
Right click anywhere in the window.
Export all or selected defects.
Save them in excel sheet or any other format.

Following are the steps to use Quality Center in real time project.

☛ Complete the preparation of test cases.
☛ Export the test cases into Quality Center and Load them in the test plan module
☛ Move the test cases from test plan tab to the test lab module.
☛ Execute the test cases and check for the results
☛ If we got any defects and raise the defects in the defect module.

There are 5 phases: Specify releases, Specify requirements, Plan tests, Execute tests, Track defects.

When we delete a folder or test from the test plan tree there are two ways. We can delete only folder or we can delete that folder, its sub folder and test also. When we delete only folder, all the tests under it moved to the unattached folder in the test plan tree.

Test lab is a functionality of Quality center using which we execute tests. We create test trees and add tests to those trees and placed them under test plan in a project. These tests then needs to imported in the Test lab module where Quality center executes them.

Matching Defects helps us to find and eliminate duplicate or similar defects in project. There are two methods to search of similar defects.

☛ Finding similar Defects which compare a selected defect with all other existing defects in project.
☛ Finding similar Text which compares a specific test string against all other existing defects in project.

Assessment requirement represents requirements that are children of analysis requirement and at lower level in tree hierarchy.
