Error guessing is an ad hoc approach, based on intuition and experience, to identify tests that are considered likely to expose errors. The basic idea is to make a list of possible errors or error-prone situations and then develop tests based on the list. What are the most common error-prone situations we have seen before? Defects’ histories are useful. There is a high probability that defects that have been there in the past are the kind that are going to be there in the future. Some items to try are: · empty or null lists/strings · zero instances/occurrences · blanks or null characters in strings · negative numbers One of the studies done by Myers (1979) states that the probability of errors remaining in the program is proportional to the number of errors that have been found so far. This alone provides a rich source of focus for productive error guessing.
Manual testing is a type of software testing in which testers execute test cases without the use of automation tools or scripts. Instead, testers follow a series of predefined steps to verify that a software application or system functions correctly and meets its requirements. Manual testing is an essential part of the software testing process and is typically performed alongside automated testing, where applicable. Here are some key aspects of manual testing: Test Case Design : Testers create test cases based on the software's requirements, specifications, and design documents. These test cases outline the steps to be followed, the expected results, and any necessary preconditions. Test Execution: Testers manually execute the test cases by interacting with the software just like a user would. They input data, navigate through the user interface, and observe the system's behavior. Exploratory Testing: In addition to predefined test cases, manual testers often perform ex
