COMPATIBILITY TESTING:
DESSS does Compatibility Testing to ensure compatibility of an application or web site with different browsers, OS, and hardware platforms. Compatibility testing is non-functional software tests and testing done on the application to verify the application's compatibility with the computing environment. Compatibility testing can be performed manually or can be driven by an automated functional or regression test suite.
The below are Computing environment which may contain some or all of the below mentioned elements:
    * Computer environment may contain all or some of the below.
    * Hardware Platform (HP / IBM etc.)
    * Peripherals of compatibility
    * Operating systems
    * Backwards compatibility.
    * Carrier compatibility
    * Hardware type or configuration
    * Varies Compilers
    * Database
    * Web server and networking
    * Browser compatibility

CONFORMANCE TESTING:
Conformance testing / type testing is type of testing to ensure whether a system meets some specified standard. Conformance testing is frequently executed by external organizations to recommend greater guarantees of compliance. This testing helps to product developer to advertise as being certified by that external organization as compliance with the standard.

FUNCTIONAL TESTING:
Validating an application or web site conforms to its specifications and correctly performs all its required 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; etc testing can be performed on an automated or manual basis using black box or white box methodologies.

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

PERFORMANCE TESTING:
Performance testing is a sub testing of Performance engineering and also serves multiple purposes. It demonstrates that the system meets performance criteria.
DESSS does Load, Stress & Performance testing, for Website, Application and Server.
Performance testing can also serve for reliability, scalability and resource usage.
Performance testing to compare two systems to find which performs better. Or it can measure what parts of the system or workload cause the system to perform slowly.
In the diagnostic case, developers use tools such as profilers to measure what parts of a device or software contribute most to the bad performance
Finally, a performance defect is identified, the higher the cost of remediation. This is fact in the case of functional testing, but even more so with performance testing, due to the end-to-end nature of its scope.
Our experts handle Stress, load, volume, scalability, Rational, Mercury, Compuware and more
DESSS does Testing and software development for mobile & complex applications.
DESSS has High quality, dedicated, flexible; QA teams both offshore/onsite.
We can create your performance tests and explain the final results.

REGRESSION TESTING:
The scope of regression testing is identical to functional Testing.
Regression testing does repeatable validation of each new release of a product or Web site.
Regressopm testing confirms that no new Quality problem was introduced during the maintenance process. And also confirms that defects have been corrected.

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 desired result. Often Stress Testing is performed using the same process as Performance Testing but employing a very high level of simulated load.

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.
