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.
xUnit is a label used for an automated testing software framework that shares significant structure and functionality that is traceable to a common progenitor SUnit. The SUnit framework was ported to Java by Kent Beck and Erich Gamma as JUnit which gained wide popularity.
The Java source code (or "src") can be found under the src/main/java directory, and the test files can be found under the src/test/java directory. [11] Maven can be used for any Java Project. [10] It uses the Project Object Model (POM), which is an XML-based approach to configuring the build steps for the project. [10]
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.
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 ...
The location (in memory) of the code for handling an exception need not be located within (or even near) the region of memory where the rest of the function's code is stored. So if an exception is thrown then a performance hit – roughly comparable to a function call [24] – may occur if the necessary exception handling code needs to be ...
try { % code that might throw an exception } catch SomeError: { % code that handles this exception } catch SomeOtherError: { % code that handles this exception } finally % optional block { % This code will always get executed } New exceptions may be created using the new_exception function, e.g.,
It supports testing Smalltalk code via test code also written in Smalltalk. SUnit was adapted for Java as JUnit which was notably popular. Subsequently, adaptations were created for many other languages; many also popular. Frameworks with similar design are labeled xUnit.
