Conformance testing

Conformance Testing is taken into account as a software testing technique to confirm that the software complies with the standards and regulations as defined by IEEE, W3C or could also be ETSI. The goal of conformance testing is to make a decision how system under test satisfies the individual requirements of a specific standard. Conformance Testing is also named as compliance testing.

It may include:

  • Performance
  • Functions
  • Robustness
  • Interoperability
  • Behaviour system

Why we do conformance testing?

  • To verify for the system’s requirements fulfill.
  • To verify whether the system documentation is complete with needful.
  • To verify the event, design and evaluation because the specifications.

What is to be tested?

  • The standards from which the implementation takes place.
  • The purpose of the system which is developed.
  • Scope of specifications
  • Specification objectives.
  • The conformance testing is started by the management with total assurance about the team and their understanding of standards, specifications and procedures.

How to perform conformance testing?

When we got to verify the system’s overall consistency, completeness and correctness with reference to the required specifications, at that moment of conformance testing are performed.

There are many methodologies for performing it, not very different for the event lifecycle stages like

  • Analysing all the possible requirements specifications
  • By preparing a Test plan.
  • Preparing a test cases and its purpose.
  • Creating a Documentation for preparing the test designs.

We always need to specialise in some aspects of specifications like subsets which are generally of three types such as ‘Profile’, ’Level’  and  ‘Modules’

Profile is a may be subset of specifications which incorporates system’s functionality which satisfies requirements and dedicated to particular group of users.

Levels are nested subset of specifications where level1 indicates the core specifications and level2 indicates level1+ additional/new functionalities.

Modules are collection of significantly correlated standards and specification.

A conformance or compliance testing is required to form sure efficiency, performance and to avoid the longer term risks for any software applications. An effective conformance testing includes

  • Analyzing standards and specifications
  • Selecting test tools and Test case.
  • Designing the test procedures
  • We have checked the required validations.
  • We have adapted relevant testing policies and certifications.

Advantages 

  1. It assures proper implementation of specifications
  2. It assures portability and also interoperability.
  3. It provides appropriate utilisation of standards.
  4. It makes a possible to make sure that interfaces and functions also are working.
  5. It also helps to identify the areas that are conformed to those which are not to be conformed like syntax and semantics.

Disadvantages

  1. To perform the testing for conformance efficiently it first has to recognise the class of system which needs to be tested along with the suitable methodology.
  2. Categorising specifications which into profiles, levels and modules.
  3. Predefining the values
  4. Designing the extensions, options and approaches which run the testing process successfully.

Conformance testing critical view are

  • Testing the methodology which are best suited
  • Selecting the test tool which will automate the testing process.
  • By clear understanding of conformance testing which shows only non-conformance testing instead of conformance.
  • It considers about policies and regulation.
