Q7. What Is Matching Defects?

  • 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.

Q8. Explain Version Control.

Version Control helps us to keep track of changes made to entities in our project including requirements. In this we can create and manage QC entities while maintaining previous version of those entities in requirements. To make changes in an entity in a version control enabled project, first we have to check out the entity. When we check out an entity, QC locks the entity, preventing other users from overwriting any changes we make. The checked out version of the entity is not visible to the other user.

We can check out an entity in the following ways:

  • Checking Out Entities Automatically
  • Checking Out Entities Manually

Q9. What Is Risk Category?

4.Rectify errors if Any.

Q11. Can We Convert Or Generate Test From The Requirements?

Yes we can convert and also generate test case from the requirements. There are two methods we can use to generate tests from the requirements:

  • Convert Requirement to test: convert requirement to test in a specified subject in the test plan tree. We can convert selected requirement or all requirements in the requirements tree.
  • Generate a test from requirements: convert requirement to a test in a specified subject in the test plan tree and a specified test set in the Test Lab modules. This method enables us to quickly run a test when analyzing our requirements.

Q12. How Does You Control The Access To A Qc Project?

We need to specify the users and the privileges for each user.

Q13. What Is Unattached Folder In Test Plan?

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.

Q14. Explain Linking Defect To Test In Quality Control?

Defects can be linked to test in the defect grid. It helps to run the tests based on the status of the defect. Defects can be linked to other entities as well such as requirements. Linking can be direct or indirect. If the defect link is with entity then QC adds a direct link and if the link is with run step then QC adds an indirect link to its run, test instance, test set and test.

Q44. What Is The Purpose Of Creating Child Requirement In Td /qc?

By Creating Child requirements to the main requirement you can evaluate the sub requirements related to the main requirements. You can link test sets and defects to the sub-requirements. This helps in 100% test coverage and its analysis.

Q45. What Is Test Set Notification, And When We Need It?

To inform any specific user we use test set notification if case of any failure.

Q46. What Are The Benefits Of Requirement Traceability?

Requirement Traceability defines a relationship between two or more requirements. When analyzing the impact of a change proposed in specific requirements, the traceability links indicate the other requirements in the requirements tree; we can establish traceability between the requirements. Using this tab in the Requirement Details view, you can add traceability link to and from selected requirement. Trace from links indicates requirements that affect a selected requirement.

Trace to links indicates requirements that are affected by a selected requirement. When a requirement change QC alerts the affected requirements this can be seen by all users. QC sends email notification to the authors of the affected requirements.

Q47. What Is Meant By Instance?

A Test Case imported from Test Plan module to Test Lab module is called an Instance of that test case. It is possible to have multiple instances of the same Test Case in the Test Lab Module.

Q48. Explain Linking Defect To Test In Quality Control.

We can link a test in our test plan to a specific defect in the Defect Grid. This is useful, for example, when a new test is created specifically for a known defect. By creating a linking, we can determine if the test should be run based on the status of the defect. We can also link the defect to other entities, such as requirements.

A defect can be linked directly or indirectly to an entity. When we add a defect link to an entity, QC adds a direct link to this entity and indirect link to other related entities. When we link a defect to run step, it adds an indirect link to its run, test instance, test set and test. If the same test is covered by a requirement, an indirect link is also added to the requirement, but indirect linkage is one directional flow.

Q49. Is 'not Covered' And 'not Run' Status The Same?

Not Covered status means all those requirements for which the test cases are not written whereas Not Run status means all those requirements for which test cases are written but are not run.

Q50. What Are The Interfaces Of Quality Center?

The interfaces of QC are:

  • Site Admin
