QA Consulting Companies: Fault-Based Testing

Process of estimating the probability of revealing errors, which is called a fault-based testing, cannot be described formally since it mainly requires intuitive approach. The fundamental idea of using this method is to list all possible faults and events/issues/situations where they may occur, and then write tests based on the list.

QA consulting companies provide comprehensive QA and testing advisory services!Now it is possible for you to obtain exhaustive information about how to enrich the quality of software under development.  

Fault/failure/error is the difference between an expected, observed, real, preassigned and theoretically correct values.  

By troubleshooting time, errors fall into the three categories:

  • structural spelling errors occurring while the code is being punched;
  • compiler errors resulting from code errors;
  • run-time errors that arise in executing the program and compiler (or operating system, virtual DOS machine) identifies that the operator is attempting to perform invalid and impossible workflow action.

In theoretical computer technology, program errors are classified by degree to which logic is violated:

  • syntax errors are committed through violation of spelling or punctuation norms while writing sentences, phrases, formulations; because of data provided by the operators, etc., namely these are grammar rule violations in the language;
  • semantic errors result from violation of precedence of the operators, function parameters and use of formulations;
  • pragmatic (logical errors occur due wrong logic of the algorithm, violation of computing intelligence and so on. These errors are the most complicated and they are quite difficult to identify.

Qa testing company is able to ensure error-free software releases so that to meet and even exceed expectations of your customers.

Typical groups of errors:

  • Address error is an error occurring due to incorrect data address.
  • Input-output error occurs during the exchange of data between storage devices, external devices.  
  • Calculation error occurs when performing arithmetical operations (for example, diverse data, zero divide and others).
  • Interface error is a program error caused by the difference in the characteristics of actual and formal parameters (as a rule, it is a semantic error detected by a compiler but it can be also a logic error arising during runtime)

When it comes to error detection, most software companies prefer to use independent testing services as it is a reliable, safe, unbiased and cost-effective way to improve the quality of IT products.
