Software Testing Interview Questions and Answers



Software Testing
Q1). What is the MAIN benefit of designing tests early in the life cycle?
Ans: It helps prevent defects from being introduced into the code.
Q2). What is risk-based testing?
Ans: Risk-based Testing is the term used for an approach to creating a test strategy that is based on prioritizing tests by risk. The basis of the approach is a detailed risk analysis and prioritizing of risks by risk level. Tests to address each risk are then specified, starting with the highest risk first.
Q3). A wholesaler sells printer cartridges. The minimum order quantity is 5. There is a 20% discount for orders of 100 or more printer cartridges. You have been asked to prepare test cases using various values for the number of printer cartridges ordered. Which of the following groups contain three test inputs that would be generated using Boundary Value Analysis?
Ans: 4, 5, 99
Q4). What is the KEY difference between preventative and reactive approaches to testing?
Ans: Preventative tests are designed early; reactive tests are designed after the software has been produced.
Q5). What is the purpose of exit criteria?
Ans: The purpose of exit criteria is to define when a test level is completed.
Q6). What determines the level of risk?
Ans: The likelihood of an adverse event and the impact of the event determine the level of risk.
Q7). When is used Decision table testing?
Ans: Decision table testing is used for testing systems for which the specification takes the form of rules or cause-effect combinations. In a decision table the inputs are listed in a column, with the outputs in the same column but below the inputs. The remainder of the table explores combinations of inputs to define the outputs produced.

Q8). What is the MAIN objective when reviewing a software deliverable?
Ans: To identify defects in any software work product.
Q9). Which of the following defines the expected results of a test? Test case specification or test design specification.
Ans: Test case specification defines the expected results of a test.
Q10). What is the benefit of test independence?
Ans: It avoids author bias in defining effective tests.

1.What kind of network performance parameters can you expect when you launch instances in cluster placement group? The network performance depends on the instance type and network performance specification, if launched in a placement group you can expect up to 10 Gbps in a single-flow, 20 Gbps in multiflow i.e full duplex Network traffic outside the placement group will be limited to 5 Gbps(full duplex). 2.To deploy a 4 node cluster of Hadoop in  AWS  which instance type can be used? First let’s understand what actually happens in a Hadoop cluster, the Hadoop cluster follows a master slave concept. The master machine processes all the data, slave machines store the data and act as data nodes. Since all the storage happens at the slave, a higher capacity hard disk would be recommended and since master does all the processing, a higher RAM and a much better CPU is required. Therefore, you can select the configuration of your machine depending on your workload. For e.g. – In th

C Interview Questions

WHAT ARE DIFFERENT TECHNIQUES FOR MAKING HASH FUNCTION? Techniques for making hash function. •  Truncation Method This is the simplest method for computing address from a key.In this method we take only a part of the key as address. •  Midsquare Method In this method the key is squared and some digits from the middle of this square are taken as address. •  Folding Method In this technique, the key is divided into different part where the length of each part is same as that of the required address, except possibly the last part. •  Division Method (Modulo-Division) In Modulo-Division method the key is divided by the table size and the remainder is taken as the address of the hash table. –>Let the table size is n then H (k) =k mod n Master C and Data Structure, in  this C and Data Structure  certification training. WHAT ARE THE ISSUES THAT HAMPER THE EFFICIENCY IN SORTING A FILE? The issues are: Length of time required by the programmer in coding a particular sorting
