¿Cómo se asegura de que la cobertura de su prueba sea buena?

How do you make sure that your test coverage is good?

How Do You Ensure Test Coverage Is Good?

1. Create a comprehensive testing strategy.
2. Create a checklist for all of the testing activities.
3. Prioritize critical areas of the application.
4. Create a list of all requirements for the application.
5. Write down the risks inherent to the application.
6. Leverage test automation.

Test coverage is defined as a technique which determines whether our test cases are actually covering the application code and how much code is exercised when we run those test cases. If there are 10 requirements and 100 tests created and if 90 tests are executed then test coverage is 90%.

1. One of the steps into achieving the 100% coverage rule is to start with a better design. E.g. many times setter and getters are considered trivial to test and thereby causing people to skip testing them and thus lowering the coverage.
2. Agreed, the best way to improve coverage is to write less code.

Condition coverage checks if both the outcomes(“true” or false”) of every condition have been exercised. The outcome of the decision point is only relevant for checking the conditions. It requires two test cases per condition for two outcomes.

To calculate the code coverage percentage, simply use the following formula: Code Coverage Percentage = (Number of lines of code executed by a testing algorithm/Total number of lines of code in a system component) * 100.

The Problem with 100% Actual Code Coverage Actual code coverage is the percentage of lines of code that are executed during an automated test run. Because 100% code coverage does not mean that there are no more bugs in the code. And because people would write useless tests to reach that 100%.
