5.What is a Quality Center Project?
A QC project is a customizable repository for the testing effort. It contains tests, test sets, execution records, defect reports and other test documentation.
6.What data sources (databases) does QC use to store and manage data?
A QC project can be stored and managed using the following data sources.
7.How does u create a project in QC?
Use the Project Administration Utility to create a QC project
8.How does u control the access to a QC project?
As a QC Admin, you can specify the users and the privileges each user will have. Privileges can also be set for groups.
9.What is a Table in QC project?
A table in QC project stores records of information about your test plan. It is part of a database.
10.How many built-in tables does QC have? What are they?
There are 6 tables accessible to the user via QC's Customize Project interface.
They are as follows:
-Test Step Table
-Test Set Table
11.What is a User-Defined field? How many can u create?
A User-Defined field is a column in a QC table activated by the user to hold project specific information. You can create unto 99 user-defined fields in a QC project
12.What are the benefits of User-defined fields?
-Store project-specific information that may be inappropriate for built-in fields
-More ways to filter and sort project information
-More ways to customize graphs and reports.
13.What are the currently supported user defined field types?
14.Where are the user-defined fields added?
The user-defined fields are added to the Test Plan tab under "Other Information"
15.How do u launch winRunner ?
Test Script tab under Test Plan module lets u
-see any WinRunner code that exists for a test
-launch WinRunner with this script loaded.
16.How do u link requirements with a test?
We link requirements to a particular test using Requirements coverage tab.
17.What is a Test Plan Tree?
The Test Plan tree is a branching structure that allows you to organize
Your entire test plan visually.
18.What are the benefits of a test plan tree?
-Visually organize your tests
-Use different criteria for groups of tests
-Insert Placeholders where needed
-Testing can start before all tests are created while keeping the plan orderly.
19.Why limit access to a Quality Center project?
You can enhance project security by assigning access privileges to all users.
20.What are Test Requirements?
Test Requirements refer to objectives or conditions that must be satisfied during testing
21.What are the categories of test requirements?
-Business Requirements->High-Level objectives of the customer requesting the product
-User requirements->Describe tasks the user must be able to accomplish with the product.
->Tasks captured in use cases or scenario descriptions.
-functional requirements->documented in a software requirements specification (SRS)
->Define the application's software functionality to enable users to
accomplish their tasks.
22.How do u check which tests are linked to a specific requirement?
Coverage View is used to check which tests are linked to a specific requirement.
Use this view to find untested requirements.
23.What does document view show?
document view displays columns for all requirements.
24.How do u customize requirements traa?
Open the "select columns" dialog to customize the requirements tree
25.What is an automated test?
An automated test is a recorded script of user actions that is played back on an application to verify correct functionality.
26.Can u use QC for automation?
Yes. QC integrates with WinRunner which is a testing tool that enables you to create and playback automated tests.
27.What are the 2 ways of adding automated tests?
-save a WR test to a Quality Center project.
-Convert a manual test to an automated one.
28.What is the importance of connecting a test case to test requirements?
-to see if all the requirements are covered.
-to map a test case associated with its requirements.
29.What are the types of graphs and reports in QC?
Progress graphs are available for all tables.
Summary graphs are available for all tables.
Test lab has additional graphs
-cross test set progress
-cross test set summary
Defects table also has Age graphs
30.What are Progress Graphs?
Progress Graphs display specified information over a period of time.
Each testing phase has a progress graph
Requirements Phase -Data grouped by fields in the REQUIREMENT table.
Planning Phase -Data from TEST table
Execution Phase -Data from RUN table
Defects Phase -Data from DEFECT table
31.What are Summary Graphs?
Summary graphs show the accumulated value of specified data in the
Quality Center project. Each testing phase has a summary graph
User may select 2 fields for grouping- graph for each field, grouped by field
32.Why use a filter?
Filters allow you to restrict the scope of data displayed in the
graph, report or grid according to criteria that you specify.
When a filter is applied, only those records that meet the filter
Conditions are displayed. Filters are available for Graphs, Reports and Grids.
33.When would you generate project documents using the standard Reports?
Feature and when would you use the Document Generator?
We use standard Reports
-to view quick reports,
-to filter/sort and customize the fields,
-and to save it to a Web page file (.htm)
We use Document Generator
-for high customization involving index, tables & attachments
-to save and edit in MS Word format (.doc)
-to choose between snapshot and Full report.
34.What icon indicates whether a test has steps?
A footprint next to the manual and automated icons indicates whether a test has steps.
35.What is a Test Set?
A Test Set is a group of tests selected from the database to achieve a
36.What is a Host Machine?
A host is a computer connected to a network, serving the project database, Which is able to execute automated tests.
37.What is a Scheduler?
The Scheduler is a QC feature that allows timed execution of automated tests. You can specify the date and time when a test will be run. This is useful for running large no. of tests unattended, such as overnight.
38.How does u open a Scheduler?
Goto-> Execution Flow tab. Right click a test to be scheduled and select "Test Run Schedule" from the pop-up menu.
39.Why use QC to track defects?
Maintains a centralized database
Standardize defect reporting
Prevent duplicate defects
Attach supporting information easily
Analyze defect data using reports and graphs.
40.How to prevent logging of duplicate defects?
Search the defect table for similar defects before entering a new one.
Use the "Find Similar" option to compare new defect and all other defects by:
Description and R&D comments.
