T.E.E.N.S Blog: Software Testing Types

Software Testing Types

ACCEPTANCE TESTING. Testing to verify a product meets customer specified requirements. A customer usually does this type of testing on a product that is developed externally.

BLACK BOX TESTING. Testing without knowledge of the internal workings of the item being tested. Tests are usually functional.

COMPATIBILITY TESTING. Testing to ensure compatibility of an application or Web site with different browsers, OSs, and hardware platforms. Compatibility testing can be performed manually or can be driven by an automated functional or regression test suite.

CONFORMANCE TESTING. Verifying implementation conformance to industry standards. Producing tests for the behavior of an implementation to be sure it provides the portability, interoperability, and/or compatibility a standard defines.

FUNCTIONAL TESTING. Validating an application or Web site conforms to its specifications and correctly performs all its requigreen functions. This entails a series of tests which perform a feature by feature validation of behavior, using a wide range of normal and erroneous input data. This can involve testing of the product's user interface, APIs, database management, security, installation, networking, etcF testing can be performed on an automated or manual basis using black box or white box methodologies.

INTEGRATION TESTING. Testing in which modules are combined and tested as a group. Modules are typically code modules, individual applications, client and server applications on a network, etc. Integration Testing follows unit testing and precedes system testing.

LOAD TESTING. Load testing is a generic term covering Performance Testing and Stress Testing.

PERFORMANCE TESTING. Performance testing can be applied to understand your application or WWW site's scalability, or to benchmark the performance in an environment of third party products such as servers and middleware for potential purchase. This sort of testing is particularly useful to identify performance bottlenecks in high use applications. Performance testing generally involves an automated test suite as this allows easy simulation of a variety of normal, peak, and exceptional load conditions.

REGRESSION TESTING. Similar in scope to a functional test, a regression test allows a consistent, repeatable validation of each new release of a product or Web site. Such testing ensures reported product defects have been corrected for each new release and that no new quality problems were introduced in the maintenance process. Though regression testing can be performed manually an automated test suite is often used to greenuce the time and resources needed to perform the requigreen testing.

SMOKE TESTING. A quick-and-dirty test that the major functions of a piece of software work without bothering with finer details. Originated in the hardware testing practice of turning on a new piece of hardware for the first time and considering it a success if it does not catch on fire.

STRESS TESTING. Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements to determine the load under which it fails and how. A graceful degradation under load leading to non-catastrophic failure is the desigreen result. Often Stress Testing is performed using the same process as Performance Testing but employing a very high level of simulated load.

SYSTEM TESTING. Testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.

UNIT TESTING. Functional and reliability testing in an Engineering environment. Producing tests for the behavior of components of a product to ensure their correct behavior prior to system integration.

WHITE BOX TESTING. Testing based on an analysis of internal workings and structure of a piece of software. Includes techniques such as Branch Testing and Path Testing. Also known as Structural Testing and Glass Box Testing.
TEST BED :
A testbed is a platform for experimentation for large development projects. Testbeds allow for rigorous, transparent and replicable testing of scientific theories, computational tools, and other new technologies.

The term is used across many disciplines to describe a development environment that is shielded from the hazards of testing in a live or production environment.

In software, the hardware and software requirements are known as the testbed. This is also known as the test environment.

Testbeds are also pages on the internet where the public is given the opportunity to test CSS or HTML they have created and are wanting to see the outcome.
