Task2_Testing techniques

Boundary value analysis and equivalence partitioning both are test case design strategies in black box testing.
Boundary value analysis:
It’s widely recognized that input values at the extreme ends of input domain cause more errors in system. More application errors occur at the boundaries of input domain. ‘Boundary value analysis’ testing technique is used to identify errors at boundaries rather than finding those exist in center of input domain.
Boundary value analysis is a next part of Equivalence partitioning for designing test cases where test cases are selected at the edges of the equivalence classes.
Test cases for input box accepting numbers between 1 and 1000 using Boundary value analysis:
1) Test cases with test data exactly as the input boundaries of input domain i.e. values 1 and 1000 in our case.
2) Test data with values just below the extreme edges of input domains i.e. values 0 and 999.
3) Test data with values just above the extreme edges of input domain i.e. values 2 and 1001.
Boundary value analysis is often called as a part of stress and negative testing.

Decision table testing is a testing technique used to test systems for which the behavior is dependent on different combinations of input conditions. It is particularly useful in situations where the behavior of a system can be expressed as a set of rules, and different combinations of input conditions lead to different outcomes.

Use case testing is a type of software testing that focuses on validating the functionality of a system based on its use cases. A use case is a description of how a user interacts with a software application to accomplish a specific task. Use case testing ensures that the system behaves as expected in real-world scenarios, covering various actions and interactions that users might perform. Use case testing is beneficial for ensuring that the software meets user requirements and functions in a way that aligns with real-world usage. It often involves testing different paths through the system to cover various scenarios, including normal and alternative flows.

During LCSAJ testing, testers identify different linear code sequences and jumps and design test cases to exercise each of them. This helps in verifying that the program's control flow behaves as expected and that all parts of the code are executed. LCSAJ, or "Linear Code Sequence and Jump" testing, is a structural testing technique used in software testing. This technique focuses on testing the different linear sequences of code and the possible jumps within those sequences. It's particularly associated with path testing and helps ensure that each linear code sequence and jump within the program is exercised.
