What is the purpose of statement coverage?
Statement Coverage is a metric that is used to measure and quantify the total number of statements that have been successfully executed in the source code. This metric is always presented as a percentage. When the coverage is 100%, it means that every statement has been executed once.
What is a statement coverage?
Statement coverage is a white box testing technique, which involves the execution of all the statements at least once in the source code. It is a metric, which is used to calculate and measure the number of statements in the source code which have been executed. This is purely a white box testing method.
Does statement coverage imply branch coverage?
“100% branch coverage implies 100% statement coverage” is correct. Below example, a = true will cover 100% of statements, but fails to test the branch where a division by zero fault is possible. Just because you cover every statement doesnt mean that you covered every branch the program could have taken.
How statement coverage is calculated?
To calculate statement coverage of the first scenario, take the total number of statements that is 7 and the number of used statements that is 6. But, we can see all the statements are covered in both scenario and we can consider that the overall statement coverage is 100%.
What is basic condition coverage?
Basic condition coverage means that every basic condition in the program is true in some test and false in some test, regardless of other conditions.
What is the main purpose of statement coverage?
The main purpose of Statement Coverage is to cover all the possible paths, lines and statements in source code. Statement coverage is used to derive scenario based upon the structure of the code under test.
How is statement coverage testing performed in development?
Statement Coverage Testing is an imperative testing method when it comes to the code validation process. It provides a healthier view on the depth of the code and the operations covered in the source code of the software application program. This step is typically performed by the development team, by using a testing tool, in most cases.
How to measure statement coverage in source code?
This methodology is a measure that tells if all possible executable statements of code in source code have been executed at least once. It is a method to ensure that each line of the source code is covered at least once by the tests. This might sound simple but caution needs to be exercised while measuring the Statement Coverage.
What does it mean when statement coverage is 100%?
Statement Coverage is a metric that is used to measure and quantify the total number of statements that have been successfully executed in the source code. This metric is always presented as a percentage. When the coverage is 100%, it means that every statement has been executed once.
