What are advanced coverage techniques in software testing?

Advanced coverage techniques in software testing include methods like mutation testing, boundary value analysis, and decision table testing. These techniques help ensure that your tests cover a wide range of scenarios and edge cases.

Can you explain mutation testing in more detail?

Sure! Mutation testing involves making small changes to your code (mutations) and then running your tests to see if they catch the changes. If your tests fail, it indicates that they are effective; if they pass, it suggests that your tests may need improvement.

What is boundary value analysis?

Boundary value analysis focuses on testing the boundaries between partitions of input values. It helps identify errors at the edges of input ranges, which are often where bugs occur.

How does decision table testing work?

Decision table testing uses a table to represent combinations of inputs and their corresponding outputs. It helps ensure that all possible scenarios are tested, especially in complex business logic.

Are there any tools that can help with these techniques?

Yes, there are several tools available for these techniques, such as PIT for mutation testing, and tools like JUnit and TestNG that can assist with boundary value analysis and decision table testing.
