It can refer to code coverage, which measures the percentage of code statements executed during testing, or functional coverage, which assesses the extent to which various features or scenarios have been tested. Common types of code coverage include statement coverage (measuring executed code lines), branch coverage (evaluating decision points), and path coverage (examining all possible execution paths). Comprehensive test coverage ensures that we have tested the software comprehensively and reduces the likelihood of hidden defects."
What to Look For: Seek candidates who can explain test coverage concepts clearly, mention different coverage metrics, and emphasize the importance of thorough testing.
How to Answer: Encourage candidates to explain their process for designing test cases using boundary value analysis, including identifying boundary values and creating test scenarios. Highlight the importance of edge cases.
Sample Answer: "When designing test cases using boundary value analysis, I start by identifying the boundary values for input parameters or conditions. For example, if a field accepts values from 1 to 100, the boundary values would be 1, 100, and the values just outside that range (0 and 101). I then create test scenarios that cover these boundary values, as well as typical values within the range. This approach helps uncover potential issues related to boundary conditions, such as off-by-one errors or validation problems."
What to Look For: Look for candidates who can describe a systematic approach to boundary value analysis, identify relevant boundary values, and demonstrate their understanding of the importance of testing edge cases.
