Question

____testing reduces the combination of values for variables to be tested without compromising the quality

Answer 1

Answer:

quality testing reduces the combination of values for variables to be tested without compromising the quality

Answer 2

Orthogonal Array Testing

Orthogonal Array Testing reduces the combination of values for variables to be tested without compromising the quality.

• Orthogonal Array Testing (OAT) is a software testing method that builds test cases using orthogonal arrays. When a system is being tested with a lot of data input, the statistical testing approach is extremely helpful. By matching and combining the inputs and evaluating the system with comparably fewer test cases for time savings, orthogonal array testing helps to maximise test coverage.
• The number of passengers, ticket number, seat numbers, and train numbers, for instance, must all be checked when a railway ticket needs to be confirmed. Testing each element or input one at a time is laborious. When the QA engineer performs testing and incorporates additional inputs, it is more effective. We can employ the Orthogonal Array testing approach in these circumstances.
• Due to the intricacy of the code, it is now difficult to offer a high-quality software solution to the customer.
• The traditional approach uses test suites, which contain test cases built from every possible combination of input values and prerequisites. Therefore, it is necessary to cover n test scenarios.
• But in reality, there are additional processes like documentation, suggestions, and user input that must be taken into account while in the testing phase, thus the testers won't have the leisure to execute all the test cases to find the flaws.
• Therefore, the test managers sought to provide maximum test coverage with the least amount of work by optimising the quantity and quality of the test cases.
