    60. What distinguishes exploratory testing from adhoc testing?

    Ans:

    Exploratory testing and ad-hoc testing share similarities but are distinct in their approaches. Exploratory testing is a structured, simultaneous learning and testing process where testers design and execute tests dynamically based on their understanding of the system. Testers create and update test cases on the fly, exploring the application while systematically evaluating its functionality. Ad-hoc testing, on the other hand, is more unplanned and lacks structure, often performed without predefined test cases.

    61.How does comprehend data-driven testing?

    Ans:

    Using the table or spreadsheet to hold test data, data-driven testing is a method of software testing. With the data-driven testing, testers can create single test script that can execute tests on all the test data from a table and anticipate that test results will be delivered in a same table. might also hear a data-driven testing referred to as a table-driven testing or parameterized testing.

    62. Distinguish Between Severity and Priority?

    Ans:

    Severity: The degree to which specific flaw can affect software is known as its severity. The parameter of “severity” describes how defect affects the software’s functionality.
