Dynamic testing or dynamic analysis is a term used in software engineering to describe the testing of the dynamic behavior of code. That is, dynamic analysis refers to the examination of the physical response from the system to variables that are not constant and change with time. In dynamic testing the software must actually be compiled and run Actually Dynamic Testing involves working with the software, giving input values and checking if the output is as expected. These are the Validation activities. Unit Tests, Integration Tests, System Tests and Acceptance Tests are few of the Dynamic Testing methodologies. Dynamic testing means testing based on specific test cases by execution of the test object or running programs. Dynamic testing is used to test software through executing it. This is in contrast to Static testing .

Portal Software Testing Soak testing involves testing a system with a significant load extended over a significant period of time, to discover how the system behaves under sustained use. For example, in software testing , a system may behave exactly as expected when tested for 1 hour. However, when it is tested for 3 hours, problems such as memory leak s cause the system to fail or behave randomly. Soak tests are used primarily to check the reaction of a subject under test under a possible simulated environment for a given duration and for a given threshold. Observations made during the soak test are used to improve the characteristics of the subject under test further. In electronics, soak testing may involve testing a system up to or above its maximum ratings for a long period of time. Some companies may soak test a product for a period of many months, while also applying external stresses such as elevated temperatures.

Unreferenced date January 2007 Performance Testing covers a broad range of engineering or functional evaluations where a material, product, system, or person is not specified by detailed material or component specification s rather, emphasis is on the final measurable performance characteristics. Testing can be a qualitative or quantitative procedure. Performance testing can refer to the Educational assessment assessment of the performance of a human examinee. For example, a behind the wheel driving Test student assessment test is a performance test of whether a person is able to perform the functions of a competent driver of an automobile. In the computer industry, software performance testing is used to determine the speed or effectiveness of a computer, network, software program or device. This process can involve quantitative tests done in a lab, such as measuring the response time or the number of MIPS millions of instructions per second at which a system functions. Qualitative attributes such as reliability, scalability and interoperability may also be evaluated. Performance testing is often done in conjunction with stress testing .

Recovery testing is the forced failure of the software in a variety of ways to verify that recovery is properly performed. Recovery testing should not be confused with reliability testing , which tries to discover the specific point at which failure occurs.Recovery testing is basically done in order to check how fast and better the application can recover against any type of crash or hardware failure etc. Type or extent of recovery is specified in the requirement specifications. It is basically testing how well a system recovers from crashes, hardware failures, or other catastrophic problems Examples of recovery testing While an application is running, suddenly restart the computer, and afterwards check the validness of the application s data integrity. While an application is receiving data from a computer network network , unplug the connecting cable. After some time, plug the cable back in and analyze the application s ability to continue receiving data from the point at which the network connection disappeared.

portal Software Testing Unreferenced date June 2009 Notability date June 2009 Localization testing is a part of software testing process focused on internationalization and localization aspects of software . Localization is the process of adapting a globalized application to a particular culture locale. Localizing an application software application requires a basic understanding of the character sets typically used in modern software development and an understanding of the issues associated with them. Localization includes the translation of the application user interface and adapting graphics for a specific culture locale. The localization process can also include translating any help content associated with the application. Localization of business solutions requires that you implement the correct business processes and practices for a culture locale. Differences in how cultures locales conduct business are heavily shaped by governmental and regulatory requirements. Therefore, localization of business logic can be a massive task. Localization testing checks how well the build has been Localized into a particular target language. This test is based on the results of globalized testing where the functional support for that particular locale has already been verified. If the product is not globalized enough to support a given language, you probably will not try to localize it into that language in the first place You still have to check that the application you re shipping to a particular market really works and the following section shows you some of the general areas on which to focus when performing a localization test.

Modal testing is a form of vibration vibration testing of an object where the natural modal frequencies, modal masses, modal damping ratios and mode shapes of the object under test are determined. A modal test not only consists of an acquisition phase, but also of an analysis phase as well. The complete process is often referred to as a Modal Analysis or Experimental Modal Analysis. There are several ways to do modal testing. Impact Hammer modal testing and Shaker vibration tester modal testing are used. In both cases energy is supplied to the system with a known frequency content. Where structural resonances occur there will be an Amplifier amplification of the response, clearly seen in the response spectra. Using the response spectra and force spectra, a transfer function can be obtained. The transfer function or frequency response function FRF is often curve fitted to estimate the modal parameters however, there are many methods of modal parameter estimation and it is the study of much research. Image M1w1Layout.jpg frame center alt Layout of a modal testingsystem Sample layout of a modal testingsystem Impact Hammer Modal Testing An ideal impact to a structure is a perfect impulse, which has an infinitely small duration, causing a constant amplitude in the frequency domain this would result in all modes of vibration being excited with equal energy. The impact hammer test is designed to replicate this however, in reality a hammer strike cannot last for an infinitely small ... cell is attached to the end of the hammer to obtain a recording of the force.
