What is the difference between verification and validation?

Correct Answer: The QA testing process that was followed in my last company where I worked was like this: First of all the Business Requirement Document was prepared as per the client?s requirement (with the muck-up screen shots) Then on the basis of the requirement document, Test Strategy, Test Plans and Test Cases were written in sequential order Once the Build is made and deployed to the different testing environments where different types of testing were performed to check whether there are any defects

Correct Answer: Basically Load, Stress and Performance Testing are the same However, Load testing is the test to check the users? response time of number of users of any one scenario of the application whereas Performance Testing is the test to check the user response time for multiple scenario of the same application

Correct Answer: Use case is nothing but the functional specification document in which all the customer requirements are documented Test case is a document which tells wat to test, steps to test and expected and actual results

Correct Answer: Walkthrogh: Very informal type of review or testing method Done by peers, so its called peer review Inspection: very technical type of review or testing method, done by the highly technically sound people

Correct Answer: Exploratory testing: means testing an application without a test plan and test script In exploring testing test explore the application on the basis on his knowledge The tester has no knowledge about the application previously He explores the application like an end user and try to use it While using the application his main motive is to find the bugs which are in the application Specification-driven testing: means to test the functionality of software according to the user requirements In this, tester inputs multiple data and monitors the outputs from, the test object In this testing tester evaluate the showstopper bugs which break the major functionality of the application This type of testing requires test plan and test

Correct Answer: Test scenarios are derived from requirement documents We follow each and every functionality (called business rules) mentioned in the requirement document One functionality can have multiple business rules For example, let us say in there is one requirement called ?Login? This ?Login? may have various scenarios For example, one scenario is, enter the right User ID and wrong password The system should display an error message Another scenario would be to enter wrong User ID and right Password The system should display an error message The third scenario could be to enter the right User Name and right Password The system should allow the user to get into the system This is how the test cases are derived from the requirement documents or from the Use Cases

Correct Answer: Regression test cases are also based on the requirement documents They are written more into detail and with every release (build), the testers need to do regression testing The criteria for regression testing are; there should be no major defects while we do our smoke test and functional testing

Correct Answer: For both client server and web based applications, the testing is the same except one thing: We test web based applications in different browsers, for example, Internet Explorer (will test in different versions like IE 50, IE 60, IE 70), Firefox, Safari (for Mac) and so on where as for client server, we don?t need to test in the browsers

Correct Answer: Similar to system testing, the *macro* end of the test scale is testing a complete application in a situation that mimics real world use, such as interacting with a database, using network communication, or interacting with other hardware, application, or system

Correct Answer: Security/penetration testing is testing how well the system is protected against unauthorized internal or external access, or willful damage This type of testing usually requires sophisticated testing techniques
