Load Testing Definition: Load testing is the process of placing demand on a application server or device and measuring its response time. The term load testing is applied in different ways in the professional software testing community. Load testing broadly refers to the practice of mocking up the anticipated usage of a software program by simulating multiple End users accessing the application under test at the same time. Since such, this testing is most applicable for multi-user systems, frequently one built using a client/server...

Conformance testing is a validation to ascertain whether a system meets some defined standard. To assist in that, several test procedures and test setups have been built up, either by the standard’s maintainers or external constitutions, mainly for testing conformance to standards. Conformance testing is frequently conducted by external organizations, sometimes the standards body itself, to give greater guarantees of compliance. Products validated in such a manner are then promoted as being certified from that outside organization...

Compatibility testing, part of software non-functional system tests, is testing performed on the application program to evaluate the application’s compatibility with the computing environment. Your client base uses a wide variety of OSs, browsers, databases, servers, clients, and hardware. Dissimilar versions, configurations, display resolutions, and web connect speeds altogether can impact the behaviour of your software and bring in costly and blocking bugs. Computing environment might comprise some or all of the below cited elements: •...

Black Box Testing is testing without any knowledge of the inner workings of the item being tested.  E.g., when black box testing is used to software engineering, the tester would only know the “valid” inputs and what the desired outputs should be, but not how the program in reality comes at those outputs.  It’s because of this that black box testing can be considered validation with reference to the specifications, no additional knowledge of the application under test is necessary.  Because this reason, the tester...

What is Alpha Testing? It is the first validation of newly built up hardware or software in a testing environment setting. Once the 1st cycle of bugs has been fixed, the software enters beta test with real users. For custom software, the customer may be invited into the vendor’s facilities for an alpha test to ascertain the customer’s requirements have been understood properly by the developer. The alpha build of the software is the build to the internal software testers, i.e., people different from the coders, sometimes to...

Why Data base testing is needed? •  To check if the data has been inserted/Deleted/Modified in the database •  Validate the Database integrity in the database •  Check the performance of the database and design the database to improve performance •  Check the database privileges for different users •  Check if the data displayed in the front end is same as that of the back end. •  Check for Data loss •  Check the Database Flags •  Database Tuning •  Check for Data security that is Encryption and Decryption...

Smoke Testing Concept – Smoke Testing Smoke testing is fundamentally related to concept of ‘project control’ where deviations of the actual project outputs are compared with desired outputs. The parameters used in project control include time, cost and performance. In projects where time is a constraint, project outputs should be assessed regularly and herein comes the functional role of smoke testing. It is therefore very commonly used while developing software so called “shrinkwrapped”. Smoke Testing – Procedure...

Data warehousing and mining provide the tools to bring data out of the silos and put it to use. Traditionally, enterprise data has been kept in information silos that are physically separate from other data repositories and serve specialized functions. Enterprise-wide reporting was difficult at best, requiring multiple data extracts and reformulation. All this data manipulation extracted a high cost in terms of accuracy and timeliness. Fortunately, the technology sector has anted up new data warehousing and mining tools to provide assistance. ...

Tag: Data Warehouse, Data Mart, Data Mining, and Decision Support A ‘data warehouse’ is a repository of an organization’s electronically stored data. Data warehouses are designed to facilitate reporting and analysis. Data Warehouse Software Testing  is not that different than any other testing project. The basic system analysis and testing process still applies. Let’s review a few of these steps and how they fit within a data warehouse context. ...

In today’s information society, an explosive growth of electronic information has been noticed. Many industrial sectors like banking, power, bio-informatics, operate huge data warehouses for collecting many different types of relevant information. This necessarily involves handling voluminous data. Data mining is the technique to do that. ...
