JMETER:
jMeter is an Open Source testing software. It is 100% pure Java application for load and performance testing. jMeter is designed to cover categories of tests like load, functional, performance, regression, etc., and it requires JDK 5 or higher. This tutorial will give you great understanding on jMeter framework needed to test an enterprise level application to deliver it with robustness and reliability.

Cyclomatic complexity
Cyclomatic complexity is a source code complexity measurement that is being correlated to a number of coding errors. It is calculated by developing a Control Flow Graph of the code that measures the number of linearly-independent paths through a program module.

Lower the Program’s cyclomatic complexity, lower the risk to modify and easier to understand. It can be represented using the below formula:
Cyclomatic complexity = E – N + 2*P
where,
E = number of edges in the flow graph.
N = number of nodes in the flow graph.
P = number of nodes that have exit points
Test Cases:
A TEST CASE is a set of conditions or variables under which a tester will determine whether a system under test satisfies requirements or works correctly.
The process of developing test cases can also help find problems in the requirements or design of an application.
