HP ALM Interview Questions and Answers
 

1) What is ALM?
 

HP ALM (Application Life Cycle Management) is a test management tool under a proprietary license.
We can access ALM/ Quality Center over the internet or intranet, via a Web browser. It involves interrelated steps such as defining release, developing requirement, designing and execution of tests, monitoring and reporting defects. QC 8.0 is the starting version and currently QC or ALM 12.0 is the latest version.

2) What are the benefits of using ALM / Quality Center?

 
•    Quality center is one of the best test management tools in the market. It has a lot of features and can be accessed through an IE browser.
•    It has a different set of modules and we can create releases, requirement and its traceability, test plan, test lab, logging defects in defect modules.
•    Different groups can be created like the BA’s, Developers and testers and it acts as a centralized point of control.
•    Defect assignment can be easily done in QC and in turn QC itself can generate emails to intimate the responsible person assigned to a particular activity.
•    QC provides various customization filters which can be used for creating reports and graphs.
•    QC can be integrated with QTP and HP Load Runner and HP Performance Center
•    QC supports virtual environments like Citrix XenApp 6.0, VMware ESX 5.0 and ESXi 5.0 (SP3).

3) What are the modules of Quality Center?
 

The Quality Center modules are:
•    Management Module: This module includes following sub modules:
•    Release module: Enable us to define release and cycles for the application management process.
•    Libraries module: Enables us to define libraries to track changes in project, reuse entities in project, or share entities across multiple projects.
•    Requirement Module: Helps us to manage requirements. This includes defining what we are testing, defining requirement topics and items, also analyzing requirements.
•    Test Plan: Enable us to develop and manage test in a hierarchical tree-structure. Tests can be linked to requirement and defects.
•    Test Resources: Enables us to manage test resources in a hierarchical tree structure. Tests resources can be associated with tests.
•    Test lab: Enables us to run tests and analyze the results.
•    Defect Module: Helps us to report defects, determine, repair priorities and reopen defects.
•    Dashboard: Helps to create graphs, reports and excel reports.

4) What is the difference between TestDirector and Quality Center?
 

Quality Center is upgraded version of TestDirector built by the same vendor Mercury (Now acquired by HP).
TestDierector Version 8.2 onwards is known as Quality Center. Quality Center is has enhanced Security/Test management /Defect management features when compared to TestDierector.

5) What is meant by test lab in Quality Center?
 

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.

6) 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.

•    Ease of Tracking: Using Advanced Reporting & Graphs provided by QC, Managers can determine various metrics useful in project tracking and monitoring.

39) How to use Quality Center in real time project?
 

After completing the test cases, we do:
•    Export the test cases into Quality Center.
•    The test cases will be loaded in the test plan module.
•    When execution is started. We move the test cases from test plan tab to the test lab module
•    In test lab, we execute the test cases and put as pass or fail or incomplete. We generate the graph in the test lab for daily report and sent to the specific user.
•    If we got any defects and raise the defects in the defect module. When raising the defects, attach the defects with the screen shot.

40) How to map the requirements with test cases in Quality Center?
 

For mapping the requirement with test cases we do:
•    In requirements tab select coverage view
•    Select requirement by clicking on parent/child or grandchild
