The Unit Testing Techniques are mainly categorized into three parts which are Black box testing that involves testing of user interface along with input and output, White box testing that involves testing the functional behaviour of the software application and Gray box testing that is used to execute test suites, test methods, test cases and performing risk analysis.Ĭode coverage techniques used in Unit Testing are listed below:įor more in refer Unit Test Example: Mock Objects

The workflow of Unit Testing is 1) Create Test Cases 2) Review/Rework 3) Baseline 4) Execute Test Cases.

Depending on the severity of a failure, the framework may halt subsequent testing. Many frameworks will also automatically flag and report, in summary, these failed test cases.

During execution of the test cases, the framework logs failing test cases. Using an automation framework, the developer codes criteria into the test to verify the correctness of the code. A coder generally uses a UnitTest Framework to develop automated test cases.These dependencies can then be eliminated. Isolating the code helps in revealing unnecessary dependencies between the code being tested and other units or data spaces in the product. This is a more thorough unit testing practice that involves copy and paste of code to its own testing environment than its natural environment. A developer could also isolate the function to test it more rigorously.They would later comment out and finally remove the test code when the application is deployed. A developer writes a section of code in the application just to test the function.A manual approach to unit testing may employ a step-by-step instructional document.

Software Engineering does not favor one over the other but automation is preferred. Unit testing is commonly automated but may still be performed manually. Developers generally use UnitTest framework to develop automated test cases for unit testing. Developers can also isolate this function to test more rigorously which reveals unnecessary dependencies between function being tested and other units so the dependencies can be eliminated. In order to execute Unit Tests, developers write a section of code to test a specific function in software application.
