kandi X-RAY | QuickTheories Summary

QuickTheories is a Java library typically used in Testing applications. QuickTheories has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. However QuickTheories has 6 bugs. You can download it from GitHub.

Traditional unit testing is performed by specifying a series of concrete examples and asserting on the outputs/behaviour of the unit under test. Property based testing moves away from concrete examples and instead checks that certain properties hold true for all possible inputs. It does this by automatically generating a random sample of valid inputs from the possible values. This can be a good way to uncover bad assumptions made by you and your code. If the word "random" is making you feel a little nervous, don't worry QuickTheories provides ways to keep your tests repeatable.

Using the java library QuickTheories, is there a builtin way to create a generator from a list of values?

Something like:

pick seems exactly what you need.

From the javadoc:

public Gen pick(java.util.List ts)

Generates a value by randomly picking one from the supplied. When shrinking, values earlier in the list will be considered "smaller".

Vulnerabilities

No vulnerabilities reported

Install QuickTheories

Add the QuickTheories jar to your build (see the badge at the top of the page for the maven coordinates of the latest version). You can run QuickTheories from JUnit, TestNG or any other test framework. Here we are using JUnit. The static import org.quicktheories.QuickTheory.qt provides access to the QuickTheories DSL. The static import org.quicktheories.generators.SourceDSL.* provides access to a DSL that allows valid inputs to be defined. This property looks pretty simple, it just checks that adding two integers always produces a number greater than 0. This couldn't possibly fail could it? That would mean math was broken. If we run this test we get something like :-. The falsified theory has highlighted something that we forgot. Math works just fine, but in Java integers can overflow.
