Hypothesis is a property-based testing library that automates test data generation based on properties or invariants defined by the developers and testers. In property-based testing, instead of specifying individual test cases, developers define general properties that the code should satisfy. Hypothesis...
Experimental model checker for testing concurrent programs. DSCheck explores interleavings of a user-provided program and helps ensure that its invariants are maintained regardless of scheduling decisions. Contents Motivation Get DSCheck Usage Development ...
The Mapping Study process revealed that five umbrella testing techniques have been developed to alleviate the oracle problem — N-version Testing, Metamorphic Testing, Assertions, Machine Learning, and Statistical Hypothesis Testing. Thus, our synthesis focuses on these techniques. The research community ...
The way to implement unit tests is using the unit testing library JUnit, which provides annotations, assertions and test executors, to annotate test cases, express invariants, execute test cases and generate reports of the results. In the following we briefly show how to express the properties ...
Testing invariants against sampled data Defining test criteria The runtime system Integration with ASDF Inheritance-based test methods Deprecated forms This document is the manual and users' guide to the 4.1.(x) series of the NST test framework, last updated for 4.1.0. NST is a unit test syst...
All of the invariants are checked after that, and they all pass.It’s important to drive the point home that the variance in action sequences that the test can generate is immense, depending on how fast-check is configured. This is the main value proposition of property-based testing! In...
Effective use of unit test frameworks and assertion libraries (JUnit,Truth,pytest,GoogleTest, etc.)serves two important purposes. Firstly, the more precisely we express the invariants we are testing, the more informative and lessbrittleour tests will be. Secondly, when those invariants don’t hold...
– is simulation testing. We just create 10’000 simulated players – and run them against the QA instance of our Server, keeping an eye on it to see whether everything makes sense (there are no assertions or crashes, database invariants still stand after we finish simulation, and so on)...
Debug assertions are used extensively. In debug build, if exception with "logical error" code (implies a bug) is being thrown, the program is terminated prematurely. It allows to use exceptions in release build but make it an assertion in debug build. ...
think in terms of broad invariants instead of case-based reasoning. There are a few classes of unit tests that are awkward with assertions, but I’ve never been limited by that. In the end, keeping the checks in the delivered code makes a difference only in the quality of your customer ...
