Can you achieve 100% path coverage?
The percentage of paths that have been exercised by a test suite. 100% path coverage implies 100% LCSAJ coverage. LCSAJ stands for Linear Code Sequence and Jump. In this the test case is executed in such a way that every path is executed at least once.
What are the required test cases to obtain 100% statement coverage?
There are two major types of White box testing techniques: Statement coverage testing and branch coverage testing. To achieve 100% statement coverage we need to check only one test case here. We ensure that A value is greater than B for input values like A=14 and B=11.
What is the minimum number of test cases that can be used to achieve 100% branch coverage?
You need to find out the shortest number of paths following which all the nodes will be covered. As you seen in diagram below in one path we can cover all statements. So 1 test case is enough to achieve 100% statement coverage.
How do you calculate test coverage in testing?
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%.
Does 100% path coverage imply 100% branch coverage?
For a test set to achieve 100% branch coverage, every branching point in the code must have been taken in each direction, at least once. The archetypical example, showing that 100% statement coverage does not imply 100% branch coverage, was already given by Alexey Frunze.
What is statement coverage with example?
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.
What is path testing with example?
In path testing method, the control flow graph of a program is designed to find a set of linearly independent paths of execution. It give complete branch coverage but achieves that without covering all possible paths of the control flow graph. McCabe’s Cyclomatic Complexity is used in path testing.
How many test cases are required for if condition?
According to the above methodology, an adequate white-box testing strategy for this function should have at least 4 test cases. The condition coverage testing strategy above, with four test cases which exercise all of the logic path conditions, is consistent with this path coverage testing methodology.
