Q1: What does the term “software testing” means?
A1: Software testing, actually, is a process used for verification and validation of designed software. It helps us to identify whether the software under test is bug free, Complete and up to demand of the customer or not. It is used to evaluate the Software for quality related issues.
Q2: Name some basic software testing methods?
A2: There are two basic methods or approaches of software testing
1. White box testing
2. Black box testing
Q3: What is white box testing?
A3: In white box testing the tester has access to all internal features of code or algorithms.
Q4: What is black box testing?
A4: In black box testing the tester has no knowledge of internal features of code and therefore the code is just like a black box for tester.
Q5: What do you mean by software quality?
A5: Quality software is one which is free of bugs, meets the customer demands, within the budget specified, easily maintainable and is user friendly.
Q6: What do you mean by software inspection?
A6: In software inspection the entire code of software is examined word by word for any errors, usually a checklist is used for checking any possible errors.
Q7: What do you mean by software verification and validation?
A7: Verification is a process to check whether the software or application built is right. Validation is a process to check whether the right software or application is built that is according to requirements of customer.
Q8: What is manual testing?
A8: In manual testing the software under test is tested manually by the tester. In this procedure a tester acts like an end user and explores entire features of the software to test whether it is free of bugs and complete in all manners according to needs of customers. Tester uses a written test procedure or plan for checking any possible errors.
Q9: What is a test plan?
A9: A test plan is a written document containing detailed information about all testing steps and procedures. It actually provides the testers a testing strategy in order to get a good quality and bug free software.
Q10: What is a test case?
A10: Test case is a sequence of steps carried out in order to check certain specified functionality or feature of the application or software under test. Test case actually contains some set of inputs to test the behavior of software and compare obtained results with expected results.
Q11: Name several stages of manual testing?
A11: There are several stages involved in manual testing. These are listed below:-
1. Unit testing
2. Integration testing
3. System testing
4. User acceptance testing
Q12: What is unit testing?
A12: Unit testing is the initial stage of testing in which testing is done by the code developer himself or sometimes a peer carries out unit testing by the help of white box testing technique.
Q13: What is integration testing?
A13: Integration testing is the second stage of manual testing procedure, usually integration testing is done by using black box technique but sometimes a combination of black box and white box techniques is used.
Q14: What is system testing?
A14: In this stage of manual testing the entire functions of software are tested in detail to verify that whether it meets the requirements or not.
Q15: What is user acceptance testing?
A15: This is the last stage of manual testing procedure. User acceptance testing is carried out to ensure whether customer will be satisfied with the product or not. Designed product is compared with customer’s requirements to carry out this test.
every anser are correct..it gives very suitable anser
its goooddddd
