What are some effective test case design techniques?

There are several effective test case design techniques, including equivalence partitioning, boundary value analysis, and decision table testing. Would you like to know more about any specific technique?

Can you explain equivalence partitioning?

Equivalence partitioning is a technique that divides input data into valid and invalid partitions. This helps in reducing the number of test cases while ensuring coverage. For example, if a field accepts values from 1 to 100, you can create partitions for values less than 1, between 1 and 100, and greater than 100.

What about boundary value analysis?

Boundary value analysis focuses on testing at the boundaries between partitions. It’s based on the idea that errors often occur at the edges of input ranges. For the previous example, you would test values like 0, 1, 100, and 101.

Are there any other techniques I should know about?

Yes, other techniques include state transition testing, use case testing, and exploratory testing. Each has its own strengths depending on the application.
