Quality Center Interview Questions with Answers

1. What is meant by test lab in Quality Centre?
Test lab is a part of Quality Centre where we can execute our test on different cycles creating test tree for each one of them. We need to add test to these test trees from the tests, which are placed under test plan in the project. Internally Quality Centre will refer to this test while running then in the test lab.
2. Can you map the defects directly to the requirements(Not through the test cases) in the Quality Centre?
In the following methods is most likely to used in this case:
  • Create your Req.Structure
  • Create the test case structure and the test cases
  • Map the test cases to the App.Req
  • Run and report bugs from your test cases in the test lab module.
The database structure in Quality Centre is mapping test cases to defects, only if you have created the bug from Application. test case may be we can update the mapping by using some code in the bug script module(from the customize project function), as per as i know, it is not possible to map defects directly to an requirements.
3. how do you run reports from Quality Centre.
This is how you do it
1. Open the Quality Centre project
2. Displays the requirements modules
3. Choose report
Analysis > reports > standard requirements report
4. Can we upload test cases from an excel sheet into Quality Centre?
Yes go to Add-In menu Quality Centre, find the excel add-In, and install it in your machine.
Now open excel, you can find the new menu option export to Quality Centre. Rest of the procedure is self explanatory.
5. Can we export the file from Quality Centre to excel sheet. If yes then how?
Requirement tab– Right click on main req/click on export/save as word, excel or other template. This would save all the child requirements
Test plan tab: Only individual test can be exported. no parent child export is possible. Select a test script, click on the design steps tab, right click anywhere on the open window. Click on export and save as.
Test lab tab: Select a child group. Click on execution grid if it is not selected. Right click anywhere. Default save option is excel. But can be saved in documents and other formats. Select all or selected option
Defects Tab: Right click anywhere on the window, export all or selected defects and save excel sheet or document.
