The following is a context diagram for the payroll system just described:Ī context diagram very clearly shows the context of a certain system with all the other entities that relate to it. Context diagrams are excellent diagrams that showcase all of these relationships in an easy to understand way. might work on their own, but enterprise application often interfaces with many other applications.įor example: A payroll system might interact with accounting application, time-sheets system for employee hours and the HR portal for employee details. Simple Applications such a calculator, notepad, etc.

Software systems rarely function as independent units. This is such a beneficial tool to create meaningful test cases and end to end acceptance tests.įor a much more comprehensive explanation and real-world usage, check out => State Transition Testing Technique for Testing Complex Applications #3) Context diagrams:

The three yellow lines are 3 end-to-end cases which when tested, will cover the most critical and most used areas of the application. Once, the ST diagram is created, you can use it to easily identify the end to end test scenarios and end-user transactions, as follows: So we normally don’t create an ST diagram for visual transitions (you can if you want to, but it is not as often used), we do it for state transitions of the core business entity. So, there might be many different visual page by page transitions but the ticket itself is in the state of being made.

of travelers- adults, children, and seniors. The first part, making the ticket, could involve navigating the system through a few pages: Please note that state transition diagrams are usually business entity-centric and not visual page by page navigation-centric.įor example: The core business entity in our case is the ticket itself that is created through the application. It is pretty sstraightforward and easy to comprehend. Look at a state transition diagram for a ticketing system. Simple, isn’t it? Let’s take on something a little more complex. This can be shown in the form of a diagram or a table. So, the state that a light bulb can be at a given point of time is ON or OFF and the event/action causing it to transition from one state to another is the flipping of the switch. State transition tables or diagrams are great analysis tools when you are looking at complex systems that undergo a lot of changes from one state to another.įor those beginners out there who are thinking, ‘what is state transition?’- Think of a light bulb that is controlled by a switch.

Correlation between Cyclometric Complexity & Code Coverage while doing White box testing.Need more information on how to use the control flow chart and Cyclomatic Complexity? Therefore, the Cyclomatic Complexity of that piece of code is 7-7+2= 2. Simply create a control flow chart as shown below and use this formula:Ĭyclomatic Complexity: = Number of connections or Lines – Number of Nodes + 2įrom the diagram, the number of nodes are 7 and connections are 7. Let’s learn how to calculate Cyclomatic Complexity it for the following program through a control flow chart. One of the uses of knowing the Cyclomatic Complexity is that it helps us understand the extent of unit testing to be done in order to achieve complete coverage (more information and links below).įlow chart is a go-to method to arrive at this measure. Here are two ways we testers use flow charts:Ī) Flow charts for control flow and statistical analysis:Ĭyclomatic Complexity is a metric that helps us measure how complex a particular software program is. It helps with remembering, understanding and serves as a quick reference.Īlso read => How to Write Complex Business Logic Test Scenarios Using Decision Table Technique To understand a process or flow of control through a flow chart is super simple. The most commonly used symbols and their meanings in a flow chart are:įor complete information on flow chart shapes, check out Flowchart Symbols. The testers will usually find the flow charts in the test plan, test strategy, requirements artifacts (BRD, FRD, etc.) or other process documents. It allows for decisions, branches, loops etc., making it a perfect tool for documentation and understanding. They use specific symbols for each task/type of action that is carried out within the process. Flow charts are best for process illustrations.
