1、11.What is testing?Finding defects in a controlled mannerDetecting the level of quality of the test objectDemonstrating the gap between specifications and the actual productDemonstrating that the end product functions as called for in the requirements2.what is software testing?Software testing： is t
2、he process of executing software in a controlled manner , in order to answer the question “ Does the software behave as specified?”Software testing is often used in association with the terms verification and validation.3.Why do we test?Provide confidence in the systemValidate software qualityIdenti

4、he following items software:1).Bug：After coding and compiling well find the mismatch between expected and actual result.A software bug is the common term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or ca
5、uses it to behave in unintended ways.2).Debugging ：is an activity which supports testing but cannot replace testing.3).Defect：The software defect is present in the software, among the undesirable or unacceptable deviation4).Error：its a mistake in programmer.E.g. when we compile a programmer in C lan
6、guage there we can see the number of errors and warning. Software error refers to the software cycle do not want to appear or unacceptable human errorDefect: Is an error found AFTER the application goes into production Bug: Is an error found BEFORE the application goes into production 6.What are the
7、 Levels of testingUnit Testing Software integration testing System testing Acceptance testing White Box: They know coding knowledgeBlack Box: They dont no coding knowledge 7.Compare verification and validationVerification: Verification is the checking or testing of items, including software for conf
8、ormance and consistency with an associated specification1). It is a Quality improvement process. 2)It is involve with the reviewing and evaluating the process. 3). It is conducted by QA team. 4). Verification is Correctness. 5). Are we producing the product right? Validation: Validation is the proce
9、ss of checking that what has beenspecified is what the user actually wanted.1). it is ensures the functionality. 2). It is conducted by development team with the help from QC team. 3). Validation is Truth. 4). Validation is the following process of verification. 5). Are we producing the right produc
10、t? 8.draw the software testing life cycle diagram.(p36)9.Test plan A test plan states what the items to be tested are , at what level they will be tested, what sequence they are to be tested in , how the test strategy will be applied to the testing of each item and describe the test environment. Som
11、e of the test plan documents are Acceptance test plan,System test planIntegration test planUnit test plan10.write a few points about test plan?The testing process of software should also require good plan. Test plan document is the most important document that brings in a process oriented approach.
12、The test plan is a mandatory document. You cant test without one. For simple, straight-forward projects the plan doesnt have to be elaborate but it must address certain items. As identified by the “American National Standards 2Institute and Institute for Electrical and Electronic Engineers Standard
13、829/1983 for Software Test Documentation”, the following components should be covered in a software test plan.11.write sample test case method.12.Write the importance of software testing.The economies of ALL developed nations are dependent on softwareMore and more systems are software controlledMore
14、 and more businesses depend on software for their success13.Why do software testing?“To find the bugs!” is the instinctive response and many people, developers and programmers included, think that thats what debugging during development and code reviews is for, so formal testing is redundant at best
15、. But a “bug” is really a problem in the code; software testing is focused on finding defects in the final product.14.Define the following items:1).Black box testing：Black-box tests in the test, the procedure can not be opened as a black box, in the process without considering the internal structure
16、 and internal features of the case, the test in the test program interface Branch2).White box testing: is also called Structural or Glass box testing.involves looking at the structure of the code. When you know the internal structure of a product, tests can be conducted to ensure that the internal operations performed according to the specification. 3).Unit testing: in which each unit( basic component) of the software is tested to verify that t
