Model Based Testing


Since their advent, software testing tools have simplified the process of testing and enhanced its accuracy. From unit testing to end-to-end testing, with the assistance of these tools software testers are effectively verifying and validating the performance, functionality, reliability, etc., of the software. Automated tools have revolutionized the process of model based testing, which is an important testing technique that defines how a system behaves in response to an action.Therefore, discussed below are some important tools used by the team of testers to implement model based testing on the software/system under test (SUT).

What is Model Based Testing?

Before we move on to discuss the model based testing tools, it is important for us to understand the the meaning of model based testing. As stated above, model based testing is a technique, which is used by the team of testers to check the runtime behavior of a software under test (SUT) against the predictions made by a formal specification of model.

Model based testing is an effective approach for creating efficient test cases from the business requirements.With the assistance of this technique, software testers can enjoy numerous benefits, like:

  • Easily maintain test cases and test suites.
  • It improves test coverage and helps in cost reduction.
  • With the assistance of model based testing, the team can run multifarious tests on numerous machines.
  • It allows early defect detection as well as increase in defect count.
  • It is more beneficial than traditional software testing.
  • Allows team to automatically generate test cases from models.
