Consider the statements regarding testing given below.Testing can be used to find all the errors in code. Testing can be used to show that a piece of software is fully correct. Testing can be used to find real errors in code. The purpose of testing is not to show correctness of software but toshow errors.Which of the following is true about the above-given statements? All the statements above are correct. The first and second statements are correct. The third and fourth statements are correct. Only the fourth statement is correct.

Question 2The purpose of software testing is to show that1 pointthe software has no defects (bugs).the program code is well structured.the software has a good architecture.the software is of good quality.the software has defects (bugs).

Choose the correct option according to the given statements.Statement 1: Unit testing focuses verification effort on the smallest unit of software design.Statement 2: In general unit testing is done by software developer. Statement 3: Unit testing comes under white box testing.Statement 4: Unit testing comes under black box testing.a)Only statement 1 and 2 are correctb)Only statement 4 is correctc)Statement 1, 2, 3, are correctd) Only statement 3 is correct

Which of the following statements correctly describes the difference between testing anddebugging?a) Testing identifies the source of defects; debugging analyzes the defects and proposesprevention activitiesb) Dynamic testing shows failures caused by defects; debugging eliminates the defects, whichare the source of failuresc) Testing removes faults; but debugging removes defects that cause the faultsd) Dynamic testing prevents the causes of failures; debugging removes the failures

Which of the following statements is a valid objective for testing?a) The test should start as late as possible so that development had enough time to create agood productb) To validate whether the test object works as expected by the users and other stakeholdersc) To prove that all possible defects are identifiedd) To prove that any remaining defects will not cause any failures
