s/w testing

Page: 1 of 3 Next > >

Software Testing is the process of testing the application or software developed by developers. Testers need to find the defaults in the software and report to developer and get corrected before releasing the software to the customer For more information logon to www.etestinghub.com I have found this site very interesting Many Thanks

Hi Friends... Somany friends asked me about What is Database testing. How we test that. What is Data migration testing. What we are trying to test in that. Now iwill tell about How to test stored procedure or stored procedure testing Test coverage criterion: each and every stored procedure must be tested at least once • Individual procedure tests • Verify the following things and compare them with design specification • Whether a stored procedure is installed in a database • Stored procedure name • Parameter names, Parameter types and the number of parameters Outputs: • When output is zero (zero row affected) • When some records are extracted • Output contains many records • What stored procedureis supposed to do • What a stored procedure not supposed to do • Write simple quaries to see if a stored procedure populates right data Parameters: • Check parameters if they are required • Call stored procedures with valid data • Call procedures with boundary data • Make each parameter invalid a time and run a procedure Return Values • Whether a stored procedure returns values • When a failure occurs, nonzero must be returned Error messages: • Make stored procedure fail and cause every error message to occur at least once • Find out any exception that doesn’t have a predefined error message Others: • Whether a stored procedure grants correct access privilege to a group/user • See if a stored procedure hits any trigger error ,index error and rule error • Look into a procedure code and make sure major branches are test covered Integration tests of procedure: • Group related stored procedures together. Call them in particular order • If there are many sequences to call a group of procedures, Find out equivalent classes and run tests to cover every class • Make invalid calling sequence and run a group of stored procedures. • Design several test sequences in which end users are likely to do business and do stress tests. If you have any queries then mail me. I will try to answer regarding database testing. In any domain. All the best

Ohh I think some of users confused with some terminology used in industry … I) Load test and stress test? Both are same??? One of the most common, but unfortunate misuse of terminology is treating "load testing" and "stress testing" as synonymous. The consequence of this ignorant semantic abuse is usually that the system is neither properly "load tested" nor subjected to a meaningful stress test. 1. Stress testing is subjecting a system to an unreasonable load while denying it the resources (e.g., RAM, disc, mips, interrupts,etc.) needed to process that load. The idea is to stress a system to the breaking point in order to find bugs that will make that break potentially harmful. The system is not expected to process the overload without adequate resources, but to behave (e.g., fail) in a decent manner (e.g., not corrupting or losing data). Bugs and failure modes discovered under stress testing may or may not be repaired depending on the application, the failure mode, consequences, etc. The load (incoming transaction stream) in stress testing is often deliberately distorted so as to force the system into resource depletion. 2. Load testing is subjecting a system to a statistically representative (usually) load. The two main reasons for using such loads is in support of software reliability testing and in performance testing. The term "load testing" by itself is too vague and imprecise to warrant use. For example, do you mean representative load," "overload," "high load," etc. In performance testing, load is varied from a minimum (zero) to the maximum level the system can sustain without running out of resources or having, transactions suffer (application-specific) excessive delay. 3. A third use of the term is as a test whose objective is to determine the maximum sustainable load the system can handle. In this usage, "load testing" is merely testing at the highest transaction arrival rate in performance testing II) Validation X Verification ? Validation ----------- 1) Am I building the right product 2) Determining if the system complies with the requirements and performs functions for which it is intended and meets the organization’s goals and user needs. It is traditional and is performed at the end of the project. 3) Am I accessing the right data (in terms of the data required to satisfy the requirement) 4) High level activity 5) Performed after a work product is produced against established criteria ensuring that the product integrates correctly into the environment 6) Determination of correctness of the final software product by a development project with respect to the user needs and requirements Verification ------------ 1) Am I building the product right 2) The review of interim work steps and interim deliverables during a project to ensure they are acceptable. To determine if the system is consistent, adheres to standards, uses reliable techniques and prudent practices, and performs the selected functions in the correct manner. 3) Am I accessing the data right (in the right place; in the right way). 4) Low level activity 5) Performed during development on key artifacts, like walkthroughs, reviews and inspections, mentor feedback, training, checklists and standards 6) Demonstration of consistency, completeness, and correctness of the software at each stage and between each stage of the development life cycle. I hope it helps … Thanks & Regards Ravi Kumar Tammineni

Hi Guys, what is diff. between CMMI and CMM levels? CMM :- this is applicable only for software industry. KPAs -18 CMMI : - This is applicable for software, out sourcing and all other industries. KPA - 25

Hi Guys, 1. what is the diff. between Client/server testing & web testing? Heavy Client vs. Browser The heavy, purpose-built clients used in client-server applications are difficult to reverse-engineer, so it was difficult for hackers to modify inputs to the server. Think about it: when you have a piece of software running on your PC, you have no way to alter the messages it sends to its server- the software has fixed buttons and widgets, with no way to access the underlying code and manipulate the commands its generates. Browsers, however, are very easy to manipulate. The source of the client-side code is available to anyone accessing the Web page, and easy to change. (Users can simply go to "View Source" under the "View" menu of Internet Explorer or other browsers, change the code, and then reload the page.) In fact, some hacker Web sites now even offer tools such as 'Web proxies' which automate this type of manipulation. 2. what is diff between 2-tier & 3-tier architecture? 2-tier is client/server and 3-tire(n tier) is webbased applications. 3. what is diff. between CMMI and CMM levels? will send it later. 4. what is diff between load and stress testing? Load Testing: testing an application under heavy loads, such as testing of a web site under a range of loads to determine at what point the system's response time degrades or fails. Stress Testing: - term often used interchangeably with 'load' and 'performance' testing. Also used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, input of large numerical values, large complex queries to a database system, etc 5. how to do verification and validation?and who will do? Verification :This is like Requirement phase when you prepare SFDs some has to review it...these kind of this...this is like static testing. Validation: This is like Unit,Integration and system testing this is done by Dev and Testers.this is like dynamic testing.(Physical execution of scripts ). if you have any qas regarding testing you can send those qa to vgangineni@gmail.com.
