1. What is bidirectional traceability?
Bidirectional traceability needs to be implemented both forward and backward (i.e., from requirements to end products and from end product back to requirements).
When the requirements are managed well, traceability can be established from the source requirement to its lower level requirements and from the lower level requirements back to their source. Such bidirectional traceability helps determine that all source requirements have been completely addressed and that all lower level requirements can be traced to a valid source.
2. What is the maximum length of the test case we can write?
We can't say exactly test case length, it depending on functionality.
3. What is internationalization Testing?
Software Internationalization is process of developing software products independent from cultural norms, language or other specific attributes of a market
4. What does black-box testing mean at the unit, integration, and system levels?
Tests for each software requirement using
Equivalence Class Partitioning, Boundary Value Testing, and more
Test cases for system software requirements using the Trace Matrix, Cross-functional Testing, Decision Tables, and more
Test cases for system integration for configurations, manual operations, etc.
New: when tester reports a defect
Open: when developer accepts that it is a bug or if the developer rejects the defect, then the status is turned into "Rejected"
Fixed: when developer make changes to the code to rectify the bug...
Closed/Reopen: when tester tests it again. If the expected result shown up, it is turned into "Closed" and if the problem persists again, it's "Reopen".
6. Smoke test? Do you use any automation tool for smoke testing?
Testing the application whether it's performing its basic functionality properly or not, so that the test team can go ahead with the application. Definitely can use.
7. When a bug is found, what is the first action?
Report it in bug tracking tool.
8. Advantages of automation over manual testing?
Time saving, resource and money
9. For Web Applications what type of tests are you going to do?
Web-based applications present new challenges, these challenges include:
- Short release cycles;
- Constantly Changing Technology;
- Possible huge number of users during initial website launch;
- Inability to control the user's running environment;
- 24-hour availability of the web site.
The quality of a website must be evident from the Onset. Any difficulty whether in response time, accuracy of information, or ease of use-will compel the user to click to a competitor's site. Such problems translate into lost of users, lost sales, and poor company image.
To overcome these types of problems, use the following techniques:
1. Functionality Testing
Functionality testing involves making Sure the features that most affect user interactions work properly. These include:
· forms
· searches
· pop-up windows
· shopping carts
· online payments
2. Usability Testing
Many users have low tolerance for anything that is difficult to use or that does not work. A user's first impression of the site is important, and many websites have become cluttered with an increasing number of features. For general-use websites frustrated users can easily click over a competitor's site.
Usability testing involves following main steps
· identify the website's purpose;
· identify the indented users ;
· define tests and conduct the usability testing
· analyze the acquired information
3. Navigation Testing
Good Navigation is an essential part of a website, especially those that are complex and provide a lot of information. Assessing navigation is a major part of usability Testing.
4. Forms Testing
Websites that use forms need tests to ensure that each field works properly and that the forms posts all data as intended by the designer.
5. Page Content Testing
Each web page must be tested for correct content from the user perspective for correct content from the user perspective. These tests fall into two categories: ensuring that each component functions correctly and ensuring that the content of each is correct.
6. Configuration and Compatibility testing
A key challenge for web applications is ensuring that the user sees a web page as the designer intended. The user can select different browser software and browser options, use different network software and on-line service, and run other concurrent applications. We execute the application under every browser/platform combination to ensure the web sites work properly under various environments.
7. Reliability and Availability Testing
A key requirement o a website is that it Be available whenever the user requests it, after 24-hours a day, every day. The number of users accessing web site simultaneously may also affect the site's availability.
8. Performance Testing
Performance Testing, which evaluates System performance under normal and heavy usage, is crucial to success of any web application. A system that takes for long to respond may frustrate the user who can then quickly move to a competitor's site. Given enough time, every page request will eventually be delivered. Performance testing seeks to ensure that the website server responds to browser requests within defined parameters.
9. Load Testing
The purpose of Load testing is to model real world experiences, typically by generating many simultaneous users accessing the website. We use automation tools to increases the ability to conduct a valid load test, because it emulates thousand of users by sending simultaneous requests to the application or the server.
10. Stress Testing
Stress Testing consists of subjecting the system to varying and maximum loads to evaluate the resulting performance. We use automated test tools to simulate loads on website and execute the tests continuously for several hours or days.
11. Security Testing
Security is a primary concern when communicating and conducting business- especially sensitive and business- critical transactions - over the internet. The user wants assurance that personal and financial information is secure. Finding the vulnerabilities in an application that would grant an unauthorized user access to the system is important.
10. What is Testing environment in your company, means how testing process start?
Testing process is going as follows:
Quality assurance unit
Quality assurance manager
Test lead
Test engineer
A simple flow between the end user and the system. It contains pre conditions, post conditions, normal flows and exceptions. It is done by Team Lead/Test Lead/Tester.
12. How you are breaking down the project among team members?
It can be depend on these following cases----
1) Number of modules
2) Number of team members
3) Complexity of the Project
4) Time Duration of the project
5) Team member's experience etc......
The place where the developers put their development modules, which are accessed by the testers to test the functionality.
14. What are the differences between these three words Error, Defect and Bug?
Error: The deviation from the required logic, syntax or standards/ethics is called as error.
There are three types of error. They are:
Syntax error (This is due to deviation from the syntax of the language what supposed to follow).
Logical error (This is due to deviation from the logic of the program what supposed to follow)
Execution error (This is generally happens when you are executing the same program, that time you get it.)
Defect: When an error found by the test engineer (testing department) then it is called defect
Bug: if the defect is agreed by the developer then it converts into bug, which has to fix by the developer or post pond to next version.
1. Start both clocks
2. When 7 min clock complete, turn it so that it restarts.
3. When 9 min clock finish, turn 7 min clocks (It has 2 mints only).
4. When 7 min clock finishes, 11 min complete.
16. What are the technical reviews?
For each document, it should be reviewed. Technical Review in the sense, for each screen, developer will write a Technical Specification. It should be reviewed by developer and tester. There are functional specification review, unit test case review and code review etc.
E- Entry Criteria
T- Task
V- Validation
X- Exit Criteria
ENTRY CRITERIA: Input with 'condition' attached.
e.g. Approved SRS document is the entry criteria for the design phase.
TASK: Procedures.
e.g. Preparation of HLD, LLD etc.
VALIDATION: Building quality & Verification activities
e.g. Technical reviews
EXIT CRITERIA: Output with 'condition' attached.
e.g Approved design document
It is important to follow ETVX concept for all phases in SDLC.
18. If the client identified some bugs to whom did he reported?
He will report to the Project Manager. Project Manager will arrange a meeting with all the leads (Dev. Manager, Test Lead and Requirement Manager) then raise a Change Request and then, identify which all the screens are going to be impacted by the bug. They will take the code and correct it and send it to the Testing Team.
19. At what phase tester role starts?
In SDLC after complition of FRS document the test lead prepare the use case document and test plan document, then the tester role is start.
20. Actually how many positive and negetive testcases will write for a module?
That depends on the module and complexity of logic. For every test case, we can identify +ve and -ve points. Based on the criteria, we will write the test cases, If it is crucial process or screen. We should check the screen,in all the boundary conditions.
If you take one screen, let's say, it has got 50 Test conditions, out of which, I have identified 5 defects which are failed. I should give the description defect, severity and defect classfication. All the defects will be considered.
Defect Classification are:
GRP : Graphical Representation
LOG : Logical Error
DSN : Design Error
STD : Standard Error
TST : Wrong Test case
TYP : Typographical Error (Cosmotic Error)

23. What are cookies? Tell me the advantage and disadvantage of cookies?
Cookies are messages that web servers pass to your web browser when you visit Internet sites. Your browser stores each message in a small file. When you request another page from the server, your browser sends the cookie back to the server. These files typically contain information about your visit to the web page, as well as any information you've volunteered, such as your name and interests. Cookies are most commonly used to track web site activity. When you visit some sites, the server gives you a cookie that acts as your identification card. Upon each return visit to that site, your browser passes that cookie back to the server. In this way, a web server can gather information about which web pages are used the most, and which pages are gathering the most repeat hits. Only the web site that creates the cookie can read it. Additionally, web servers can only use information that you provide or choices that you make while visiting the web site as content in cookies. Accepting a cookie does not give a server access to your computer or any of your personal information. Servers can only read cookies that they have set, so other servers do not have access to your information. Also, it is not possible to execute code from a cookie, and not possible to use a cookie to deliver a virus.
24. What is stub? Explain in testing point of view?
Stub is a dummy program or component, the code is not ready for testing, it's used for testing...that means, in a project if there are 4 modules and last is remaining and there is no time then we will use dummy program to complete that fourth module and we will run whole 4 modules also. The dummy program is also known as stub.
25. Define Brain Stromming and Cause Effect Graphing?
BS:
A learning technique involving open group discussion intended to expand the range of available ideas
OR
A meeting to generate creative ideas. At PEPSI Advertising, daily, weekly and bi-monthly brainstorming sessions are held by various work groups within the firm. Our monthly I-Power brainstorming meeting is attended by the entire agency staff.
OR
Brainstorming is a highly structured process to help generate ideas. It is based on the principle that you cannot generate and evaluate ideas at the same time. To use brainstorming, you must first gain agreement from the group to try brainstorming for a fixed interval (eg six minutes).
CEG:
A testing technique that aids in selecting, in a systematic way, a high-yield set of test cases that logically relates causes to effects to produce test cases. It has a beneficial side effect in pointing out incompleteness and ambiguities in specifications.
