Top 20 HP ALM Interview Questions
Hewlett Packard – Application Lifecycle Management (HP-ALM) is a tool developed by HP Enterprise to manage and track the development and testing of applications or software.
It handles various activities like requirement management, test planning, and test execution.
- HP ALM also covers different types of testing like performance testing, load testing etc., by using its corresponding tools.
- With this effective and great tool, even the stakeholder’s task is made easier and simple in viewing the application progress at any point of its development process.
- HP ALM has two interfaces, Server Side, and Client Side. Server side will be handled by Site Admin whereas Client Side is handled by ALM.
- HP ALM supports SQL commands with the help of Data Base engine.
- HP ALM does not directly interact with the application or software that is to be developed. It just gathers the information of the application like reports, graphs etc.
- We can import requirements, test cases, and defects into HP ALM from the system.
- HP ALM is accessible by Bas, customers, testing teams and development teams.
Few Uses of HP ALM:
1) HP ALM is used for planning and tracking of projects.
2) Through HP ALM we can share the libraries and can reuse them across the projects.
3) As HP ALM supports multi-environment so that it can be used across various mobile devices.
4) The traceability matrix of requirements and defects is real time in HP ALM. This helps the QA team to view the reports at any point of time.
5) With this HP ALM, testing and development teams keep track of requirements and manage them.

Q. #1) Define the HP ALM workflow?
Ans) ALM workflow includes
i) Release Specification
ii) Requirement Specification
iii) Test Planning
iv) Test Execution
v) Defect Tracking
Q. #2) Name the predefined groups of HP ALM?
Ans) The predefined groups of HP ALM are
ii) Project Manager
iii) QA Tester
iv) TD Admin
The permissions of these above groups cannot be changed at any cost. And also these group names cannot be renamed/edited. Neither these groups can be deleted from ALM.

Hence for this, we require release and cycle management.
Q4) How can you enter data through HP Sprinter?
A) Sprinter is used to entering test data into the application to be tested by matching the column names against the respective field names.
- Through this Sprinter, we can make the manual testing more effective and efficient.
- Multiple sets of data are directly inserted into the application at a stretch by matching the fields.
- First, select/decide the row that we need to insert and then click/tap on the “inject” icon. This directly inserts the data into the respective fields.
Q5) How can you use both HP QC 10.0 and HP ALM on a same machine or client?
A) At first, we have to install HP QC 10.0 and then have to install HP ALM on the same machine. Both the versions can be used simultaneously but should be in different instances of a browser.

A) A Dashboard gives a brief and quick view of the project status to the project managers or stakeholders.
Q10) How can we create automated test scripts or performance test scripts from ALM?
A) One cannot create automated test scripts or performance test scripts using ALM. For that, we need to use HP QTP/UFT for functional scripts and HP Load Runner for performance test scripts and create the scripts.
We should upload or save the above-created scripts into ALM and can execute, monitor, schedule and report the same.
Q11) Can we delete the default test configuration from HP ALM?
A) No, the default test configuration cannot be deleted. However, we can edit the same and can work on it.
Q12) How does the name “HP ALM” evolved from QC?
A) Earlier “Quality Center” was named as “Test Director” by Mercury Interactive.
