software testing-5
Describe me the difference between validation and verification?
Verification: typically involves reviews and meetings to evaluate documents, plans, code, requirements, and specifications. This can be done with checklists, issues lists, walkthroughs, and inspection meetings.
Validation: typically involves actual testing and takes place after verifications are completed. The term 'IV & V' refers to Independent Verification and Validation
Is coding required in SQA robot?
Yes, to enhance the script for testing the business logic, and when we write the user define the functions.
What do you mean by “set up the test environment and provide full platform support?
We need to provide the following for setting up the environment
1) Required software
2) Required hardware
3) Required testing tools
4) Required test data
After providing these we need to provide support for any problems that occur during the testing process.
What are the two ways to copy a file in windows?
1) Using the copy menu item in the edit menu.
2) By dragging the file where ever you want to copy it like a floppy
If the functionality of an application had an inbuilt bug because of which the test script fails, would you automate the test?
No, we do the automation once the application is tested manually and it is stabilized. Automation is for regression testing.
What is the bug reporting tool used?
Rational ClearQuest
TestDirectror
PVCS Tracker
Did use SQA Manager?
Yes. For creating test plan and defect reporting/tracking.
You find a bug and the developer says “It’s not possible” what do u do?
I’ll discuss with him under what conditions (working environment) the bug was produced. I’ll provide him with more details and the snapshot of the bug.
How do you help developer to track the fault s in the software?
By providing him with details of the defects which include the environment, test data, steps followed etc… and helping him to reproduce the defect in his environment.
Were you able to meet deadlines?
Absolutely.
What is Polymorphism? Give example.
In object-oriented programming, polymorphism refers to a programming language's ability to process objects differently depending on their data type or class. More specifically, it is the ability to redefine methods for derived classes.
For example, given a base class shape, polymorphism enables the programmer to define different circumference methods for any number of derived classes, such as circles, rectangles and triangles.
No matter what shape an object is, applying the circumference method to it will return the correct results. Polymorphism is considered to be a requirement of any true object-oriented programming language (OOPL).
What are the different types of MRs?
MR for suggestions,
MR for defect reports,
MR for documentations changes
What is test Metrics?
Test metrics contains follwoing details:
• Total test
• Test run
• Test passed
• Test failed
• Tests deferred
• Test passed the first time
What is the use of Metrics?
Provide the accurate measurement of test coverage.
If you have shortage of time, how would you prioritize you testing?
Use risk analysis to determine where testing should be focused. Since it's rarely possible to test every possible aspect of an application, every possible combination of events, every dependency, or everything that could go wrong, risk analysis is appropriate to most software development projects. Considerations can include:
• Which functionality is most important to the project's intended purpose?
• Which functionality is most visible to the user?
• Which functionality has the largest safety impact?
• Which functionality has the largest financial impact on users?
• Which aspects of the application are most important to the customer?
• Which aspects of the application can be tested early in the development cycle?
• Which parts of the code are most complex, and thus most subject to errors?
• Which parts of the application were developed in rush or panic mode?
• Which aspects of similar/related previous projects caused problems?
• Which aspects of similar/related previous projects had large maintenance expenses?
• Which parts of the requirements and design are unclear or poorly thought out?
• What do the developers think are the highest-risk aspects of the application?
• What kinds of problems would cause the worst publicity?
• What kinds of problems would cause the most customer service complaints?
• What kinds of tests could easily cover multiple functionalities?
• Which tests will have the best high-risk-coverage to time-required ratio?
What is the impact of environment on the actual results of performance testing?
Environment plays an important role in the results and effectiveness of test, particularly in the area of performance testing. Some of the factors will be under our control, while others will not be. These may involve the DBMS, the operating system or the network. Some of the items that we cannot control unless you can secure a stand-alone environment (which will generally be unrealistic) are:
- Other traffic on the network
- Other process running on the server
- Other process running on the DBMS
What is stress testing, performance testing, Security testing, Recovery testing and volume testing.
Stress testing: Testing the system if it can handle peak usage period loads that result from large number of simultaneous users, transactions or devices. Monitoring should be performed for throughput and system stability.
Performance Testing: Testing the system whether the system functions are being performed in an acceptable timeframe under simultaneous user load. Timings for both read and update transactions should be gathered to determine whether. This should be done stand-alone and then in a multi-user environment to determine the transaction throughput.
Security Testing: Testing the system for its security from unauthorized use and unauthorized data access.
Recovery Testing: Testing a system to see how it responds to errors and abnormal conditions, such as system crash, loss of device, communications, or power.
Volume Testing: Testing to the system to determine if it can correctly process large volumes of data fed to the system. Systems can often respond unpredictably when large volume causes files to overflow and need extensions.
What criteria you will follow to assign severity and due date to the MR?
Defects (MR) are assigned severity as follows:
Critical: show stoppers (the system is unusable)
High: The system is very hard to use and some cases are prone to convert to critical issues if not taken care of.
Medium: The system functionality has a major bug but is not too critical but needs to be fixed in order for the AUT to go to production environment.
Low: cosmetic (GUI related)
What is user acceptance testing?
It is also called as Beta Testing. Once System Testing is done and the system seems stable to the developers and testers, system engineers usually invite the end users of the software to see if they like the software. If the users like the software the way it is then software will be delivered to the user. Otherwise necessary changes will be made to the software and software will pass through all phases of testing again.
What is manual testing and what is automated testing?
Manual testing involves testing of software application by manually performing the actions on the AUT based on test plans.
Automated testing involves testing of a software application by performing the actions on the AUT by using automated testing tool (such as WinRunner, LoadRunner) based on test plans
Verification: typically involves reviews and meetings to evaluate documents, plans, code, requirements, and specifications. This can be done with checklists, issues lists, walkthroughs, and inspection meetings.
