Images Compatibility Testing

Compatibility testing:

      Compatibility testing is a type of software testing used to ensure compatibility of the system/application/website built with various other objects such as other web browsers, hardware platforms, users (in case if it’s very specific type of requirement, such as a user who speaks and can read only a particular language), operating systems etc. This type of testing helps find out how well a system performs in a particular environment that includes hardware, network, operating system and other software etc.

      It tests whether the application or the software product built is compatible with the hardware, operating system, database or other system software or not.

It is a type of non-functional testing.

Compatibility testing, part of software non-functional tests, is testing conducted on the application to evaluate the application's compatibility with the computing environment.

Images Boundary Value Analysis

Boundary value analysis:

Boundary value analysis (BVA) is based on testing at the boundaries between partitions.

     

      ‘Boundary value analysis’ testing technique is used to identify errors at boundaries rather than finding those exist in center of input domain.

     

      Boundary value analysis is a next part of Equivalence partitioning for designing test cases where test cases are selected at the edges of the equivalence classes.

Example:

As an example, consider a printer that has an input option of the number of copies to be made, from 1 to 99. To apply boundary value analysis, we will take the minimum and maximum (boundary) values from the valid partition (1 and 99 in this case) together with the first or last value respectively in each of the invalid partitions adjacent to the valid partition (0 and 100 in this case). In this example we would have three equivalence partitioning tests (one from each of the three partitions) and four boundary value tests.
