JUnit is a test automation framework for the Java programming language.JUnit is often used for unit testing, and is one of the xUnit frameworks.. JUnit is linked as a JAR at compile-time.
Combines F# Quotation decompilation, evaluation, and incremental reduction implementations to allow test assertions to be written as plain, statically checked quoted expressions which produce step-by-step failure messages. Integrates configuration-free with all exception-based unit testing frameworks including xUnit.net, NUnit, and MbUnit.
In computer software testing, a test assertion is an expression which encapsulates some testable logic specified about a target under test. The expression is formally presented as an assertion, along with some form of identifier, to help testers and engineers ensure that tests of the target relate properly and clearly to the corresponding specified statements about the target.
Tests can be written without using a framework to exercise the code under test using assertions, exception handling, and other control flow mechanisms to verify behavior and report failure. Some note that testing without a framework is valuable since there is a barrier to entry for the adoption of a framework; that having some tests is better ...
Assertions are often enabled during development and disabled during final testing and on release to the customer. Not checking assertions avoids the cost of evaluating the assertions while (assuming the assertions are free of side effects) still producing the same result under normal conditions. Under abnormal conditions, disabling assertion ...
Test development: test procedures, test scenarios, test cases, test datasets, test scripts to use in testing software. Test execution: testers execute the software based on the plans and test documents then report any errors found to the development team. This part could be complex when running tests with a lack of programming knowledge.
The Iowa State JML tools provide an assertion checking compiler jmlc which converts JML annotations into runtime assertions, a documentation generator jmldoc which produces Javadoc documentation augmented with extra information from JML annotations, and a unit test generator jmlunit which generates JUnit test code from JML annotations.
This approach uses a single method of the Assert class for all assertions, passing a Constraint object that specifies the test to be performed. This constraint-based model is now used internally by NUnit for all assertions. The methods of the classic approach have been re-implemented on top of this new model. [citation needed]
